Question

I’m using a UEC Cloud (with kvm)

• Can I restore an image, in a VM, without booting it? (like freezing the image and then restarting the image on that exact tick while skipping the whole booting)
• Is that what ‘Snapshot’ is?

If it’s possible, then what are the general steps to do it?

Answer 1

I think that virsh save and virsh restore are the commands you are looking for.
Virsh is a part of libvirt, an abstraction layer that can talk to different virtualization solutions like kvm and xen.

I don’t know how these two commands are implemented.
