seems like another regression of libvitxml
(In reply to Tomas Jelinek from comment #3) > seems like another regression of libvitxml Yes. The Vdsm side should be fixed now with https://gerrit.ovirt.org/#/c/81610/ . The bug is that Vdsm doesn't do the hugepages preparation in the new engine XML flow; the cleanup stage should be OK. To fix this BZ, we need to make sure that Engine works well: it should 1. send the custom properties encoded in the domain metadata (same values as before, let's just put them in the metadata) 2. do the same additions to the domain XML that Vdsm used to. CC Arik to make sure he's aware
Vdsm patch merged, but Engine needs to send the custom properties in the domain XML metadata, once that is done we can move to MODIFIED.
Engine side is merged as well
regression caused by domain xml. Doesn't need doc string.
