Helo Nir,
No I do not have libvirt logs enabled.
I restored the vm from the snapshot and retried. It did boot but at the same time it did
not merge again when I tried it. On the other hand when I cloned it and tried to recreate
the situation the image did merge.
Is it possible that the image is corrupted for any reason beyond live merge failure,so the
merge fails regardles?
This is a production vm so I cannot play a lot with it :-(
I should probably clone it give the clone to production and see if this continues to
happen.
Thank you for your help. I ll let you know if I can find out anything new.
