Hi, Tried to install Buster on Xen HVM + OVMF. Installation completed successfully, but unable to boot (Windows HVM guest has no boot problem). Re-install Buster with BIOS and boot succeeded. OVMF boot NOT supported on Debian ? I hope someone could point me in the right direction. Best regards, John Mok

I have never used Xen but I use Qemu/KVM via virtmanager on a Debian 10 host. I have installed several UEFI (OVMF) booting guest OSes, including Debian with no particular problem. The problem of your Debian guest not booting could be caused by the Debian installer not being run in UEFI mode, the media upon Debian is to be installed being not GPT type, the mandatory EFI partition being absent, the GRUB bootloader being not installed or incorrectly set-up, and so on... Debian installation guide (UEFI and general): https://www.debian.org/releases/stable/amd64/ch03s06.en.html#UEFI https://www.debian.org/releases/stable/amd64/index.en.html There is an OVMF page on the Xen wiki, detailing setup and troubleshooting: https://wiki.xenproject.org/wiki/OVMF

Hi didier, Thanks for prompt reply. I installed Debian Buster with UEFI boot on my ThinkPad P52 successfully without any boot problem. I think it is related to Xen HVM + OVMF. Anyone has an idea what went wrong ? Thanks.

Hello, did you use the "bios='ovmf'" option in the xl.cfg file of your Debian Xen guest? By default, even if OVMF is installed/present on your OS host, Xen uses Seabios, not OVMF (so legacy Bios instead of true UEFI). This could explain why Microsoft Windows runs without problem as your Xen guest: Win10 can run either on UEFI or a Legacy Bios.

Hi Didier, Yes, I set BIOS='ovmf', and the Debian installation showed UEFI installer.
