I see virt-manager can make snapshots if qcow2 is used. I also see a save button.Suppose I want to save a machine, is it ok to do save and maybe at reboot (of host, not guest) I can resume the machine?Or I have to make a snapshot?
With virt-manager can I save a guest then reboot the host
virt manager
The managed save option of virt-manager pauses the guest and dumps its memory (and CPU state) to a save file. The corresponding start reloads the guest so that it can continue on from where it left off.This works with Linux-based guests but I can say that empirically it does not work with Windows-based guests (they don't successfully restart).virsh managedsave {guest}...virsh start {guest}
