* kvm/security_group: Make Security Group Python 3 compatible
This script only runs on the KVM Hypervisors and these all support
Python 3.
As Python 2 is deprecated at the end of 2019 we need to fix these
scripts to work under Python 3.
CentOS 7, 8 and Ubuntu 16.04 and 18.04 all have Python 3 installed
by default.
Ubuntu 20.04 will no longer have Python 2 installed and therefor
this script needs to be modified to work with Python 3.

Ubuntu 14.04 will go EOL in April 2019. With a new CloudStack
release close to that date we can drop support for this Ubuntu
version and the master branch of CloudStack.
Ubuntu 16.04 (Xenial) and 18.04 (Bionic) both have systemd and
more recent Java versions which make it easier to run the CloudStack
KVM Agent on them.
In addition libvirt and Qemu are more up to date with features
which allow VMs to run better.
Yet to be implemented features in KVM can also leverage the newer
version of Qemu and libvirt without the need of taking older
version of them into account.

This adds and allows Ubuntu 18.04 to be used as KVM host. In addition,
on the UI when hypervisor version key is missing, this adds and display
the host os and version detail which is useful to show the KVM host
os and version.
When cache mode 'none' is used for empty cdrom drives, systemvms
and guest VMs fail to start on newer libvirtd such as Ubuntu bionic.
The fix is ensure that cachemode is not declared when drives are empty
upon starting of the VM. Similar issue logged at redhat here:
https://bugzilla.redhat.com/show_bug.cgi?id=1342999
The workaround is to ensure that we don't configure cachemode for
cdrom devices at all. This also fixes live VM migration issue.

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.

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 introduces a new certificate authority framework that allows
pluggable CA provider implementations to handle certificate operations
around issuance, revocation and propagation. The framework injects
itself to `NioServer` to handle agent connections securely. The
framework adds assumptions in `NioClient` that a keystore if available
with known name `cloud.jks` will be used for SSL negotiations and
handshake.
This includes a default 'root' CA provider plugin which creates its own
self-signed root certificate authority on first run and uses it for
issuance and provisioning of certificate to CloudStack agents such as
the KVM, CPVM and SSVM agents and also for the management server for
peer clustering.
Additional changes and notes:
- Comma separate list of management server IPs can be set to the 'host'
global setting. Newly provisioned agents (KVM/CPVM/SSVM etc) will get
radomized comma separated list to which they will attempt connection
or reconnection in provided order. This removes need of a TCP LB on
port 8250 (default) of the management server(s).
- All fresh deployment will enforce two-way SSL authentication where
connecting agents will be required to present certificates issued
by the 'root' CA plugin.
- Existing environment on upgrade will continue to use one-way SSL
authentication and connecting agents will not be required to present
certificates.
- A script `keystore-setup` is responsible for initial keystore setup
and CSR generation on the agent/hosts.
- A script `keystore-cert-import` is responsible for import provided
certificate payload to the java keystore file.
- Agent security (keystore, certificates etc) are setup initially using
SSH, and later provisioning is handled via an existing agent connection
using command-answers. The supported clients and agents are limited to
CPVM, SSVM, and KVM agents, and clustered management server (peering).
- Certificate revocation does not revoke an existing agent-mgmt server
connection, however rejects a revoked certificate used during SSL
handshake.
- Older `cloudstackmanagement.keystore` is deprecated and will no longer
be used by mgmt server(s) for SSL negotiations and handshake. New
keystores will be named `cloud.jks`, any additional SSL certificates
should not be imported in it for use with tomcat etc. The `cloud.jks`
keystore is stricly used for agent-server communications.
- Management server keystore are validated and renewed on start up only,
the validity of them are same as the CA certificates.
New APIs:
- listCaProviders: lists all available CA provider plugins
- listCaCertificate: lists the CA certificate(s)
- issueCertificate: issues X509 client certificate with/without a CSR
- provisionCertificate: provisions certificate to a host
- revokeCertificate: revokes a client certificate using its serial
Global settings for the CA framework:
- ca.framework.provider.plugin: The configured CA provider plugin
- ca.framework.cert.keysize: The key size for certificate generation
- ca.framework.cert.signature.algorithm: The certificate signature algorithm
- ca.framework.cert.validity.period: Certificate validity in days
- ca.framework.cert.automatic.renewal: Certificate auto-renewal setting
- ca.framework.background.task.delay: CA background task delay/interval
- ca.framework.cert.expiry.alert.period: Days to check and alert expiring certificates
Global settings for the default 'root' CA provider:
- ca.plugin.root.private.key: (hidden/encrypted) CA private key
- ca.plugin.root.public.key: (hidden/encrypted) CA public key
- ca.plugin.root.ca.certificate: (hidden/encrypted) CA certificate
- ca.plugin.root.issuer.dn: The CA issue distinguished name
- ca.plugin.root.auth.strictness: Are clients required to present certificates

Since libvirt 1.2.2 libvirt will properly create volumes
using RBD format 2.
We can use libvirt to creates the volumes which strips a bit of
code from the CloudStack Agent's responsbility.
RBD format 2 is already used by all volumes created by CloudStack.
This format is the most recent format of RBD and is still actively
being developed.
This removes the support for Ubuntu 12.04 as that does not have the
proper libvirt version available.

This commit implements basic Security Grouping for KVM in
Basic Networking.
It does not implement full Security Grouping yet, but it does:
- Prevent IP-Address source spoofing
- Allow DHCPv6 clients, but disallow DHCPv6 servers
- Disallow Instances to send out Router Advertisements
The Security Grouping allows ICMPv6 packets as described by RFC4890
as they are essential for IPv6 connectivity.
Following RFC4890 it allows:
- Router Solicitations
- Router Advertisements (incoming only)
- Neighbor Advertisements
- Neighbor Solicitations
- Packet Too Big
- Time Exceeded
- Destination Unreachable
- Parameter Problem
- Echo Request
ICMPv6 is a essential part of IPv6, without it connectivity will break or be very
unreliable.
For now it allows any UDP and TCP packet to be send in to the Instance which
effectively opens up the firewall completely.
Future commits will implement Security Grouping further which allows controlling UDP and TCP
ports for IPv6 like can be done with IPv4.
Regardless of the egress filtering (which can't be done yet) it will always allow outbound DNS
to port 53 over UDP or TCP.
