CLOUDSTACK-8715: Add VirtIO channel to all Instances for the Qemu Guest
Agent
This commit adds a additional VirtIO channel with the name
'org.qemu.guest_agent.0'
to all Instances.
With the Qemu Guest Agent the Hypervisor gains more control over the
Instance if
these tools are present inside the Instance, for example:
* Power control
* Flushing filesystems
In the future this should allow safer snapshots on KVM since we can
instruct the
Instance to flush the filesystems prior to snapshotting the disk.
More information: http://wiki.qemu.org/Features/QAPI/GuestAgent
Keep in mind that on Ubuntu AppArmor still needs to be disabled since the
default
AppArmor profile doesn't allow libvirt to write into /var/lib/libvirt/qemu

[Guest Agent] fix UI bugs
----
> Add support for qemu-guest-agent to libvirt provider
> ----------------------------------------------------
>
> Key: CLOUDSTACK-8715
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-8715
> Project: CloudStack
> Issue Type: New Feature
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: KVM
> Reporter: Sten Spans
> Assignee: Wido den Hollander
> Labels: kvm, libvirt, qemu, systemvm
> Fix For: Future
>
>
> The qemu guest agent is a newer part of qemu/kvm/libvirt which exposes quite
> a lot of useful functionality, which can only be provided by having an agent
> on the VM. This includes things like freezing/thawing filesystems (for
> backups), reading files on the guest, listing interfaces / ip addresses, etc.
> This feature has been requested by users, but is currently not implemented.
> http://users.cloudstack.apache.narkive.com/3TTmy3zj/enabling-qemu-guest-agent
> The first change needed is to add the following to the XML generated for KVM
> virtual machines,:
> <channel type='unix'>
> <source mode='bind'/>
> <target type='virtio' name='org.qemu.guest_agent.0'/>
> </channel>
> This provides the communication channel between libvirt and the agent on the
> host. All in all a pretty simple change to LibvirtComputingResource.java /
> LibvirtVMDef.java
> Secondly the qemu-guest-agent package needs to be added to the systemvm
> template.
