Problem starting Windows 11 EE

Hi, I configured a W11EE VM using virt-manager and joined it to my work domain. Everything was fine for a while. Later when I tried to reboot, I got the "Preparing Automatic Repair" message and when I selected "Startup Repair", I got the error "Startup repair couldn't repair your PC". I then went to command prompt, started 'diskpart' and ran "list disk" and got the error "there are no fixed disks to show". I have tried re-installing several times - it always ends up in this state. A few details of my system: host OS: OpenSUSE 15.5 libvirt version: 9.0.0-150500.4.3 virtio drivers: https://fedorapeople.org/groups/virt/virtio-win/direct-downloads/archive-... Disk device type: virtio bitlocker is enabled in VM I am able to configure and use W11-professional without joining my work domain. The above problem isn't seen there. I booted the broken VM using my linux rescue disk image and examined the partition table. Everything seems to be proper. But windows isn't able to find the disk as I explained above. Can anybody provide any pointers for troubleshooting this ? Thanks, -Rahul
