> 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.
