On actual testing, I could see that kvmheartbeat.sh script fails on NFS
server failure and stops the agent only. Any HA VMs could be launched
in different hosts, and recovery of NFS server could lead to a state
where a HA enabled VM runs on two hosts and can potentially cause
disk corruptions. In most cases, VM disk corruption will be worse than
VM downtime. I've kept the sleep interval between check/rounds but
reduced it to 10s. The change in behaviour was introduced in #2722.

Prevents errors while migrating VM from ISO:
Test 1: Deploy VM from ISO -> Live migrate VM to another host -> ERROR
Test 2: Register ISO using Direct Download on KVM -> Deploy VM from ISO -> Live migrate VM to another host -> ERROR
- Prevent NullPointerException migrating VM from ISO
- Prevent mount secondary storage on ISO direct downloads on KVM
This tries to provide a threshold based fix for #2873 where swappinness of VR is not used until last resort. By limiting swappiness unless actually needed, the VR system degradation can be avoided for most cases. The other change is around not starting baremetal-vr by default on all VRs, according to the spec https://cwiki.apache.org/confluence/display/CLOUDSTACK/Baremetal+Advanced+Networking+Support only vmware VRs need to run it and that too only as the last step of the setup/completion, so we don't need to run it all the time.

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.

* 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!

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.

There is a race condition in the monitoring of the migration process on KVM. If the monitor wakes up in the tight window after the migration succeeds, but before the migration thread terminates, the monitor will get a LibvirtException “Domain not found: no domain with matching uuid” when checking on the migration status. This in turn causes CloudStack to sync the VM state to stop, in which it issues a defensive StopCommand to ensure it is correctly synced.
Fix: Prevent LibvirtException: "Domain not found" caused by the call to dm.getInfo()
When user creates a snapshot (manual or recurring), snapshot remains on
the primary storage, even if the snapshot is transferred successfully to
secondary storage. This is causing issues because XenServer can only hold
a limited number of snapshots in its VDI chain, preventing the user from
creating new snapshots after some time, when too many old snapshots are
present on the primary storage.
The documentation of Libvirt specifies the requirement of using an XML namespace,
when having metadata in the Domain XML. The Nuage extenstion metadata was not
adhering to this specification, and the lastest Libvirt version ignores it in that case.

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.
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.
The first PR(#1176) intended to solve #CLOUDSTACK-9025 was only tackling the problem for CloudStack deployments that use single hypervisor types (restricted to XenServer). Additionally, the lack of information regarding that solution (poor documentation, test cases and description in PRs and Jira ticket) led the code to be removed in #1124 after a long discussion and analysis in #1056. That piece of code seemed logicless (and it was!). It would receive a hostId and then change that hostId for other hostId of the zone without doing any check; it was not even checking the hypervisor and storage in which the host was plugged into.
The problem reported in #CLOUDSTACK-9025 is caused by partial snapshots that are taken in XenServer. This means, we do not take a complete snapshot, but a partial one that contains only the modified data. This requires rebuilding the VHD hierarchy when creating a template out of the snapshot. The point is that the first hostId received is not a hostId, but a system VM ID(SSVM). That is why the code in #1176 fixed the problem for some deployment scenarios, but would cause problems for scenarios where we have multiple hypervisors in the same zone. We need to execute the creation of the VHD that represents the template in the hypervisor, so the VHD chain can be built using the parent links.
This commit changes the method com.cloud.hypervisor.XenServerGuru.getCommandHostDelegation(long, Command). From now on we replace the hostId that is intended to execute the “copy command” that will create the VHD of the template according to some conditions that were already in place. The idea is that starting with XenServer 6.2.0 hotFix ESP1004 we need to execute the command in the hypervisor host and not from the SSVM. Moreover, the method was improved making it readable and understandable; it was also created test cases assuring that from XenServer 6.2.0 hotFix ESP1004 and upward versions we change the hostId that will be used to execute the “copy command”.
Furthermore, we are not selecting a random host from a zone anymore. A new method was introduced in the HostDao called “findHostConnectedToSnapshotStoragePoolToExecuteCommand”, using this method we look for a host that is in the cluster that is using the storage pool where the volume from which the Snaphost is taken of. By doing this, we guarantee that the host that is connected to the primary storage where all of the snapshots parent VHDs are stored is used to create the template.
Consider using Disabled hosts when no Enabled hosts are found
This also closes#2317
* Cleanup and Improve NetUtils
This class had many unused methods, inconsistent names and redundant code.
This commit cleans up code, renames a few methods and constants.
The global/account setting 'api.allowed.source.cidr.list' is set
to 0.0.0.0/0,::/0 by default preserve the current behavior and thus
allow API calls for accounts from all IPv4 and IPv6 subnets.
Users can set it to a comma-separated list of IPv4/IPv6 subnets to
restrict API calls for Admin accounts to certain parts of their network(s).
This is to improve Security. Should an attacker steal the Access/Secret key
of an account he/she still needs to be in a subnet from where accounts are
allowed to perform API calls.
This is a good security measure for APIs which are connected to the public internet.
