Xen project Mailing List

Hi all,

I have a similar issue like this one. I hope you guys can help me sort it out.

My system is gentoo with UEFI, and my partition layout is:

EFI partition/

Â gentoo/

Â Â grubx64.efi # for grub

Â Â xen-4.4.1.efiÂ

Â Â xen.cfg

Â Â kernel-gentoo

/ # root for the rest of my system

I ran "efibootmgr -c -l 'gentoo\xen-4.4.1.efi' -L Xen" and reboot the system. During the boot, the screen display something I think is related to Xen, then it turns blank, no disk activity at all. Looks like halted.

My xen.cfg looks like this:

[global]

default=xen

[xen]

options=console=vga

kernel=kernel-gentoo root=....

# i am not using an initramfs file

Thanks,

Xi Shen

Sorry, my mistake, I saw the mention of grub in the next para and my
pattern matching system went off ;-)

Great!
