    to bad the kvm restructure didn't come through. we'd have this in a separate file ;)

>             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.
