Hello! I have rhv 4.4.2 and NFS storage type for HE Domain Storage. I updated to 4.4.4 by guide (https://www.ovirt.org/documentation/upgrade_guide/#Updating_a_self-hosted_en...) and reboot Hosted Engine VM. After this VM is not booting. Connected to console I see next error: BdsDxe: failed to load Boot0001 "UEFI Misc Device"... After "Press any key" I got BIOS screen, go to Device Manager -> Drive Health Manager I see nothing. I suggest that something happened with VM config. Check /etc/ovirt-hosted-engine/hosted-engine.conf All looks correctly (I checked UUID to Domain Storage and etc.) Check /var/run/ovirt-hosted-engine-ha/vm.conf. After encoding base64 I found something like this: <source file="/rhev/data-center/0000-0000-0000-0000-0000/6916940d-b21b-4739-9d6b-4f7ff9e72a9e/images/9a17d31d-30f8-480d-a106-2fa7f0d48c40/a817c10b-0366-4c05-b512-e6beb8308b5d All path is correct only zero after data-center/. I changed it to real path, decode to base64 and try to start VM with hosted-engine --vm-start --vm-conf=PATH_TO_NEW_FILE. Nothing. I see similar error. Could someone help me in this case?
