@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.
