libvirt: post virt-clone, unchanged values in resulting XML file from original XML file

Hey guys,

I just cloned a simple VM with this command:

Code:

virt-clone --original linax2-new --name linax1-new --file /scratch/vm/linax1.img

This created a new linax1.img and linax1.xml file. However inspecting the linax1.xml file reveals this "channel" under devices:

Code:

    <channel type='unix'>
      <source mode='bind' path='/var/lib/libvirt/qemu/channel/target/domain-linax2-new/org.qemu.guest_agent.0'/>
      <target type='virtio' name='org.qemu.guest_agent.0'/>
      <address type='virtio-serial' controller='0' bus='0' port='1'/>
    </channel>

It makes direct reference to the original domain it was cloned from (linax2-new). Is this okay? Can it be changed? *Should* it be changed?

This refers to the Guest Agent installed on your source VM.
libvirt Wiki states:

Quote:

Libvirt does not guarantee any support of direct use of the guest agent.

This means that virt-clone doesn't handle this option. You need to adjust these settings manually.
