CLOUDSTACK-8715: Add channel to Instances for 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
* Fetching Network information
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
This commit does not add any communication methods through API-calls, it
merely
adds the channel to the Instances and installs the Guest Agent in the SSVMs.
