Hi,
Could I do this with snapshots? I suspect not since I see virDomainSnapshotRedefinePrep() calling
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'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 task, I would like to save (and distribute) the domain state, so that I just restore from memory.
However, I can't seems to change the UUID or the name of a domain once it is saved.
Nor do I seem able to rename a domain while it is running.
I can obviously duplicate both the disks and the file to which I saved the domain state using "virsh save".
But I seem unable to rename before I restore.. Any ideas?
virDomainDefCheckABIStability which raises the error here:
Out of curiosity does anyone know what horrors might befall me if I were to remove the lines protecting against name and UUID changes? Then compile my own libvirt...
The comment in the code says name can be changed, but I'm guessing I would have to change the UUID too. Does anyone see how that would create issues? I'm not sure how libvirt uses the UUID internally.
