tl;dr : Is it possible to dump the memory of a live VM and then use that memory with a copy of the same VM.



I have a running VM for which I did virsh save myvm which created a file.
With this file, I can easily do virsh restore file to have the VM immediately ready with RAM loaded.



Now, I'd like to make copies of this VM. I use qemu-img create -f qcow2 -b myvm.qcow2 newvm.qcow2 (use myvm.qcow2 as a backing file).
For this new VM, I'd also like to already load the memory, skipping the boot step of the VM.



I tried to virsh restore newvm --xml newvm.xml where newvm contains a new uuid and points to the newvm.qcow2, however libvirt does not allow this: unsupported configuration: Target domain uuid xx does not match source yy
