Backup KVM guest machine config? (the right way)
 

What is the right way to backup kvm guest machine config?
Should it that be over: virsh dumpxml [GuestMachne] > GuestMachne.xml (while the vm is up and running)

OR

copy following from kvm hypervisor (once GuestMachne is down)
/etc/libvirt/qemu/[GuestMachne].xml

OR it does not matter (both are OK/contains this same content)?

I get the feeling that the xml could be copied at any stage. Guess I'd have to test that.

Not a lot going on with the config file. Most machines are not that technical. I guess if you have a number of mac addresses and unique stuff that will mean you'd want to save it.

virsh dumpxml and virsh edit work in all circumstances. Poking around in system files always carries the risk that files might be at unexpected locations.
