Re: [libvirt-users] [libvirt] libvirt external disk-only snapshot will pause the VM?
Thanks very much Eric! This is exactly what I guessed, I just wondering
where I could find this piece of code and control the the pause time of
guest, while the snapshot being taken? thanks !
Best,
Yuanzhen

The guest will temporarily pause, but the time that it remains paused
will be a fraction of a second. In practice, it is no longer than the
time that the guest is paused when doing live migration.
