When configuring a pre-setup primary storage we can enter the name-label of the storage that is going to be used by ACS and is already set up in the host. The problem is that we can use any String of characters there, and this String does not need to be a UUID. When listing volumes from a primary storage that has such conditions, the list will return all of the volumes in the cloud because the “API framework” will ignore that value as it is not a UUID type.
This introduces a new global setting `vm.configdrive.primarypool.enabled` to toggle creation/hosting of config drive iso files on primary storage, the default will be false causing them to be hosted on secondary storage. The current support is limited from hypervisor resource side and in current implementation limited to `KVM` only. The next big change is that config drive is created at a temporary location by management server and shipped to either KVM or SSVM agent via cmd-answer pattern, the data of which is not logged in logs. This saves us from adding genisoimage dependency on cloudstack-agent pkg.
The APIs to reset ssh public key, password and user-data (via update VM API) requires that VM should be shutdown. Therefore, in the refactoring I removed the case of updation of existing ISO. If there are objections I'll re-put the strategy to detach+attach new config iso as a way of updation. In the refactored implementation, the folder name is changed to lower-cased configdrive. And during VM start, migration or shutdown/removal if primary storage is enable for use, the KVM agent will handle cleanup tasks otherwise SSVM agent will handle them.

* Primary Storage count for an account does not decrease when a Data Disk is deleted
When a data disk is created and not attached in a running VM, the "deleteVolume" will not decrement the count for used primary storage in the VMs accounting information. The property that is not being decremented is called "primarystoragetotal"; this information can be retrieved via "listAccounts" API method.
Steps to reproduce this issue:
1 - Create an account, deploy a VM in it
2 - Check the primary storage count for the account with listAccounts API
3 - Create a data disk
4 - Check the primary storage count for the account with listAccounts API
5 - Delete the Data disk
6 - Check the primary storage count for the account with listAccounts API - It is the same as before deleting the data disk (it should not be the same as the value in step 2!)

* CLOUDSTACK-9184: Fixes#2631 VMware dvs portgroup autogrowth
This deprecates the vmware.ports.per.dvportgroup global setting.
The vSphere Auto Expand feature (introduced in vSphere 5.0) will take
care of dynamically increasing/decreasing the dvPorts when running out
of distributed ports . But in case of vSphere 4.1/4.0 (If used), as this
feature is not there, the new default value (=> 8) have an impact in the
existing deployments. Action item for vSphere 4.1/4.0: Admin should
modify the global configuration setting "vmware.ports.per.dvportgroup"
from 8 to any number based on their environment because the proposal
default value of 8 would be very less without auto expand feature in
general. The current default value of 256 may not need immediate
modification after deployment, but 8 would be very less which means
admin need to update immediately after upgrade.

ACS is accounting the resources properly when deploying VMs with custom service offerings. However, there are other methods (such as updateResourceCount) that do not execute the resource accounting properly, and these methods update the resource count for an account in the database. Therefore, if a user deploys VMs with custom service offerings, and later this user calls the “updateResourceCount” method, it (the method) will only account for VMs with normal service offerings, and update this as the number of resources used by the account. This will result in a smaller number of resources to be accounted for the given account than the real used value. The problem becomes worse because if the user starts to delete these VMs, it is possible to reach negative values of resources allocated (breaking all of the resource limiting for accounts). This is a very serious attack vector for public cloud providers!

CloudStack SSO (using security.singlesignon.key) does not work anymore with CloudStack 4.11, since commit 9988c26, which introduced a regression due to a refactoring: every API request that is not "validated" generates the same error (401 - Unauthorized) and invalidates the session.
However, CloudStack UI executes a call to listConfigurations in method bypassLoginCheck. A non-admin user does not have the permissions to execute this request, which causes an error 401:
{"listconfigurationsresponse":{"uuidList":[],"errorcode":401,"errortext":"unable to verify user credentials and/or request signature"}}
The session (already created by SSO) is then invalidated and the user cannot access to CloudStack UI (error "Session Expired").
Before 9988c26 (up to CloudStack 4.10), an error 432 was returned (and ignored):
{"errorresponse":{"uuidList":[],"errorcode":432,"cserrorcode":9999,"errortext":"The user is not allowed to request the API command or the API command does not exist"}}
Even if the call to listConfigurations was removed, another call to listIdps also lead to an error 401 for user accounts if the SAML plugin is not enabled.
This pull request aims to fix the SSO issue, by restoring errors 432 (instead of 401 + invalidate session) for commands not available. However, if an API command is explicitly denied using ACLs or if the session key is incorrect, it still generates an error 401 and invalidates the session.
This extends securing of KVM hosts to securing of libvirt on KVM
host as well for TLS enabled live VM migration. To simplify implementation
securing of host implies that both host and libvirtd processes are
secured with management server's CA plugin issued certificates.
Based on whether keystore and certificates files are available at
/etc/cloudstack/agent, the KVM agent determines whether to use TLS or
TCP based uris for live VM migration. It is also enforced that a secured
host will allow live VM migration to/from other secured host, and an
unsecured hosts will allow live VM migration to/from other unsecured
host only.
Post upgrade the KVM agent on startup will expose its security state
(secured detail is sent as true or false) to the managements server that
gets saved in host_details for the host. This host detail can be accesed
via the listHosts response, and in the UI unsecured KVM hosts will show
up with the host state of ‘unsecured’. Further, a button has been added
that allows admins to provision/renew certificates to KVM hosts and can
be used to secure any unsecured KVM host.
The `cloudstack-setup-agent` was modified to accept a new flag `-s`
which will reconfigure libvirtd with following settings:
listen_tcp=0
listen_tls=1
tcp_port="16509"
tls_port="16514"
auth_tcp="none"
auth_tls="none"
key_file = "/etc/pki/libvirt/private/serverkey.pem"
cert_file = "/etc/pki/libvirt/servercert.pem"
ca_file = "/etc/pki/CA/cacert.pem"
For a connected KVM host agent, when the certificate are
renewed/provisioned a background task is scheduled that waits until all
of the agent tasks finish after which libvirt process is restarted and
finally the agent is restarted via AgentShell.
There are no API or DB changes.

The new CA framework introduced basic support for comma-separated
list of management servers for agent, which makes an external LB
unnecessary.
This extends that feature to implement LB sorting algorithms that
sorts the management server list before they are sent to the agents.
This adds a central intelligence in the management server and adds
additional enhancements to Agent class to be algorithm aware and
have a background mechanism to check/fallback to preferred management
server (assumed as the first in the list). This is support for any
indirect agent such as the KVM, CPVM and SSVM agent, and would
provide support for management server host migration during upgrade
(when instead of in-place, new hosts are used to setup new mgmt server).
This FR introduces two new global settings:
- `indirect.agent.lb.algorithm`: The algorithm for the indirect agent LB.
- `indirect.agent.lb.check.interval`: The preferred host check interval
for the agent's background task that checks and switches to agent's
preferred host.
The indirect.agent.lb.algorithm supports following algorithm options:
- static: use the list as provided.
- roundrobin: evenly spreads hosts across management servers based on
host's id.
- shuffle: (pseudo) randomly sorts the list (not recommended for production).
Any changes to the global settings - `indirect.agent.lb.algorithm` and
`host` does not require restarting of the mangement server(s) and the
agents. A message bus based system dynamically reacts to change in these
global settings and propagates them to all connected agents.
Comma-separated management server list is propagated to agents on
following cases:
- Addition of a host (including ssvm, cpvm systevms).
- Connection or reconnection by the agents to a management server.
- After admin changes the 'host' and/or the
'indirect.agent.lb.algorithm' global settings.
On the agent side, the 'host' setting is saved in its properties file as:
`host=<comma separated addresses>@<algorithm name>`.
First the agent connects to the management server and sends its current
management server list, which is compared by the management server and
in case of failure a new/update list is sent for the agent to persist.
From the agent's perspective, the first address in the propagated list
will be considered the preferred host. A new background task can be
activated by configuring the `indirect.agent.lb.check.interval` which is
a cluster level global setting from CloudStack and admins can also
override this by configuring the 'host.lb.check.interval' in the
`agent.properties` file.
Every time agent gets a ms-host list and the algorithm, the host specific
background check interval is also sent and it dynamically reconfigures
the background task without need to restart agents.
Note: The 'static' and 'roundrobin' algorithms, strictly checks for the
order as expected by them, however, the 'shuffle' algorithm just checks
for content and not the order of the comma separate ms host addresses.

During storage expunge domain resource statistics for primary storage space resource counter is not updated for domain. This leads to the situation when domain resource statistics for primary storage is overfilled (statistics only increase but not decrease).
Global scheduled task resourcecount.check.interval > 0 provides a workaround but not fixes the problem truly because when accounts inside domains use primary_storage allocation/deallocation intensively it leads to service block of operation.
NB: Unable to implement marvin tests because it (marvin) places in database weird primary storage volume size of 100 when creating VM from template. It might be a sign of opening a new issue for that bug.
CloudStack volumes and templates are one single virtual disk in case of XenServer/XCP and KVM hypervisors since the files used for templates and volumes are virtual disks (VHD, QCOW2). However, VMware volumes and templates are in OVA format, which are archives that can contain a complete VM including multiple VMDKs and other files such as ISOs. And currently, Cloudstack only supports Template creation based on OVA files containing a single disk. If a user creates a template from a OVA file containing more than 1 disk and launches an instance using this template, only the first disk is attached to the new instance and other disks are ignored.
Similarly with uploaded volumes, attaching an uploaded volume that contains multiple disks to a VM will result in only one VMDK to being attached to the VM.
FS: https://cwiki.apache.org/confluence/display/CLOUDSTACK/Support+OVA+files+containing+multiple+disks
This behavior needs to be improved in VMWare to support OVA files with multiple disks for both uploaded volumes and templates. i.e. If a user creates a template from a OVA file containing more than 1 disk and launches an instance using this template, the first disk should be attached to the new instance as the ROOT disk and volumes should be created based on other VMDK disks in the OVA file and should be attached to the instance.

This feature allows using templates and ISOs avoiding secondary storage as intermediate cache on KVM. The virtual machine deployment process is enhanced to supported bypassed registered templates and ISOs, delegating the work of downloading them to primary storage to the KVM agent instead of the SSVM agent.
Template and ISO registration:
- When hypervisor is KVM, a checkbox is displayed with 'Direct Download' label.
- API methods registerTemplate and registerISO are both extended with this new parameter directdownload.
- On template or ISO registration, no download job is sent to SSVM agent, CloudStack would only persist an entry on template_store_ref indicating that template or ISO has been marked as 'Direct Download' (bypassing Secondary Storage). These entries are persisted as:
template_id = Template or ISO id on vm_template table
store_id NULL
download_state = BYPASSED
state = Ready
(Note: these entries allow users to deploy virtual machine from registered templates or ISOs)
- An URL validation command is sent to a random KVM host to check if template/ISO location can be reached. Metalink are also supported by this feature. In case of a metalink, it is fetched and URL check is performed on each of its URLs.
- Checksum should be provided as indicated on #2246: {ALGORITHM}CHKSUMHASH
- After template or ISO is registered, it would be displayed in the UI
Virtual machine deployment:
When a 'Direct Download' template is selected for deployment, CloudStack would delegate template downloading to destination storage pool via destination host by a new pluggable download manager.
Download manager would handle template downloading depending on URL protocol. In case of HTTP, request headers can be set by the user via vm_template_details. Those details should be persisted as:
Key: HTTP_HEADER
Value: HEADERNAME:HEADERVALUE
In case of HTTPS, a new API method is added uploadTemplateDirectDownloadCertificate to allow user importing a client certificate into all KVM hosts' keystore before deployment.
After template or ISO is downloaded to primary storage, usual entry would be persisted on template_spool_ref indicating the mapping between template/ISO and storage pool.
Steps to reproduce issue
Deploy a VM
Take snapshot of the root volume
Delete the snapshot
Before the garbage collector has run, shutdown the VM and assign the VM to other user.
When garage collector executes NPE shows in the logs.
This happens when the root disk size is overridden. The primary storage limit check should be performed based on overridden size instead of template size. Enabled root disk resize tests to run on simulator as well.
This feature allow admins to dedicate a range of public IP addresses to the SSVM and CPVM, such that they can be subject to specific external firewall rules. The option to dedicate a public IP range to the System VMs (SSVM & CPVM) is added to the createVlanIpRange API method and the UI.
Solution:
Global setting 'system.vm.public.ip.reservation.mode.strictness' is added to determine if the use of the system VM reservation is strict (when true) or preferred (false), false by default.
When a range has been dedicated to System VMs, CloudStack should apply IPs from that range to
the public interfaces of the CPVM and the SSVM depending on global setting's value:
If the global setting is set to false: then CloudStack will use any unused and unreserved public IP
addresses for system VMs only when the pool of reserved IPs has been exhausted
If the global setting is set to true: then CloudStack will fail to deploy the system VM when the pool
of reserved IPs has been exhausted, citing the lack of available IPs.
UI Changes
Under Infrastructure -> Zone -> Physical Network -> Public -> IP Ranges, button 'Account' label is refactored to 'Set reservation'.
When that button is clicked, dialog displayed is also refactored, including a new checkbox 'System VMs' which indicates if range should be dedicated for CPVM and SSVM, and a note indicating its usage.
When clicking on button for any created range, UI dialog displayed indicates whether IP range is dedicated for system vms or not.
