In general, a good idea and would be useful for flushing out disk IO and
doing clean shutdown of VRs and vms. There are some outstanding issues, but the
feature is nice.
I've not tested this, I suppose @wido would have tested this for
Debian/Ubuntu based kvm hosts, we'll also need testing efforts on centos6 and 7
based kvm hosts.
> 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.
