Hi, all. I currently operates several VMs on cockpit-machines, and I want to move those VMs to oVirt. When I tried oVirt 4.5 last month, installation failed and I tried oVirt 4.3.10, it works. I moved several qcow2 disks on hyper-converged gluster and I attached them on VMs and some disks boot and operate well, but some cannot boot due to XFS issues - https://access.redhat.com/solutions/4582401. So, I installed newest ovirt-engine on CentOS 8 Stream. I installed ovirt-node via ovirt-node-ng-installer-4.5.0-2022051313.el8.iso. I applied vdsm-gluster-cli patch manually on ovirt nodes, that does not applied on ovirt-ng iso. https://github.com/oVirt/vdsm/commit/2da10debcea0b9f2e235dc18c2d567e6aa42.... Then, I encountered the following boot error when I launched several VMs that worked on cockpit-machines and oVirt 4.3.10. BdsDxe: failed to load Boot0001 "UEFI Misc Device" from PciRoot (0x0)/Pci(0x2,0x3)/Pci(0x0,0x0): Not Found BdsDxe: No bootable option or device was found BdsDxe: Press any key to enter the Boot Manager Menu. Is there any patch that I should apply? Best Regards Minseok Jang. ---- PS. FIY, I leave my current status.
