Hello there,
I take external disk-only snapshot, but deleted the snapshot by mistaken.
Is there anyway to reboot the system from backing file instead of
reinstalled the system again? thanks!
Best,
Yuanzhen

Are you using libvirt? If so, this question is better asked on
libvirt-users@redhat.com; but the short answer is modify your domain XML
to point to the backing file names, then reboot. If not, then modify
your qemu command line to point to the backing files.

yes, I found the way, we can reboot from original virtual disk via pick
boot from existing disk img.
Best,
