@Pilow Does disk show up after you do the snapshot? If it is able to do the snapshot there is a high chance it can boot up. So try booting up (and check for disk) and shut it down and do the snapshot at that time if the disk show up. It helps to boot up on the old v5 commit and check from that side too if you have both copy before the commit update. Yep I can confirm that snapshot doesn't always work. But using the older v5 that used to work before the update does get it showing up on the newer v5 commit if I go through whole snapshot, revert, etc. one of those case work.

@wilsonqanda Yes, BIOS as well, assuming I am remembering right haha. If you just pick whatever is closest and go with it I doubt you'll run into issues, if you do just make a post here and I'm sure someone will be willing to help out or work on a new template or something.

@wilsonqanda Downgrading the EKD2 package fix it for now, as posted: yum downgrade edk2-20180522git4b8552d-1.5.1.xcpng8.3

@olivierlambert Thanks I see that clarifies things. Took me a while to realize that this is to change the management xcp-ng connection to the network and not the VMs.
