Create multiple domains from single saved domain state (is UUID/name fixed?)
Hi,
I would like to save a running domain (ie. disk + memory) and be able to
restore it multiple times creating duplicates of the orignal domain all
starting from the same state.
Use case:
I'm building a task-processing system for use in a CI flow.
I want to run multiple VMs in parallel using the same image (always
starting from the same state).
And to avoid needlessly booting between each

Re: Create multiple domains from single saved domain state (is UUID/name fixed?)
...es wants is to use virt-builder, it could cause some
problems if you started all of them. What Michael wants is:
virsh save running_domain saved-image-file.img
virsh save-image-edit saved-image-file.img
Hope that helped,
Martin

Re: Create multiple domains from single saved domain state (is UUID/name fixed?)
...here last week. You could find it by searching
for this topic in the mailing list archives: "Clone VM with saved state".
That being said I'd be very glad if you could update here when you find a
complete solution.

Agree, but is that possible with libvirt?
If you do that (restore a previously running image with a different MAC

Yeah, probably I wouldn't change the MAC address. As I want to attach the
VMs to different networks.
I rely on the IP being in a different subnet to identify the VM in

Re: Create multiple domains from single saved domain state (is UUID/name fixed?)
Fair enough :)
I just wanted to make sure it wasn't supported... I'm probably better off
using QEMU directly. I totally understand that libvirt makes some sane
decisions that makes sense for data center management.
I'm not sure why it couldn't be done. But honestly hacking libvirt to
violate a core invariant is probably asking for trouble :)
