--------------------------------------
Summary: 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
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.

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.
