Re: [Xen-users] How to boot xen with EUFI?

[Xi Shen <davidshen84@xxxxxxxxx>]

I have managed to get my dom0 started with grub+uefi support. But my dom0 does not have access to efivars, and it is said I have to boot with xen.efi to be able to have this feature.

Thanks,

David

Hi,

I have Linux 3.17 kernel, and xen 4.4.2 build with EFI support. I followed some guide online to configure the xen.cfg file, but I can not get my xen boot.

After I boot my computer, the screen shows something about xen, then turns black.

I was wondering if I need to configure my ESP as well. But I could not find any references.

I actually just set this up yesterday, whilst working on rebuilding one of my workstations and wanting to play with EFI.

The approach I took involved using gummiboot as the EFI boot loader; I mounted my ESP on /boot, installed gummiboot on the ESP, as well as the linux kernel, initramfs, xen.efi and xen.cfg. I then created a simple entry so that gummiboot would load the xen.efi package on bootup. That was pretty much it - on reboot I got the hypervisor startup messages, before it moved over to dom0 booting up. This was on Arch Linux running the 3.17.1 kernel and the latest xen AUR package i'd been working on. I had also tried rEFInd as a boot loader, but was having issues with it and the UEFI firmware on the motherboard (ASUS Sabertooth 990FX rev 1.0 )
