To be honest, this code was written by me about two years ago , which is
not used for now. I created the PR because you guys can judge this code are
useful or not. I have no comments if we revert some of the commits (or even
all).
1. for the default port, if most of you agree, I will revert the related
commits.
2. I agree. I did not remove it in the commits. However, I change the
'vmName'.vport as the first virtio port, because cloud-early-config get the
publickey and boot args from /dev/vport0p1.
3. rom my point of view, python is easy for testing, the data send/receive
are already implemented. If you want to replace it with Java, that's very good.
for now, python works fine in my testing, I even use it for guest agent command
testing. btw, do you want replace patachviasocket.pl with java ? I replace it
with the python script in the PR.
> 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.
