[Xen-users] Xen UEFI how to install and configure

["AR (aka AleiPhoenix)" <aleiphoenix@xxxxxxxxx>]

Hi, all

I'm new to xen recently. I've managed to install the xen on a BIOS machine, and boot into xen dom0, setup a domU guest, all goes well.

So I decided to turn my desktop into a xen server. It's running on UEFI.

The machine runs on Gentoo Linux with kernel 3.11.0.

I'm using xen-4.2.2 , it's built with efi USE FLAG , and install the xen-4.2.2.efi into /usr/lib64/efi/xen-4.2.2.efi.

My EFI partition is located in /boot/efi , the GRUB2 efi is located in /boot/efi/EFI/GRUB2/grub.efi.

I've tried putting xen-4.2.2.efi to /boot/efi/EFI/gentoo/xen-4.2.2.efi . with the xen-4.2.2.cfg in the same directory.

Added a efi boot entry with `efibootmgr --create --gpt --disk /dev/sda --part 1 --write-signature --label "XEN" --loader "\\EFI\\gentoo\\xen-4.2.2.efi"`.

But it failed to boot (black screen, then the machine tried the next boot entry, grub2 menu showed up.)

the xen-4.2.2.cfg looks like

[global]

default = gentoo

[gentoo]

options=console=vga loglvl=all

kernel=vmlinuz-3.11.0-gentoo

ramdisk=initrd-3.11.0-gentoo

kernel and ramdisk file just located in /boot

The docs didn't help much.

http://xenbits.xen.org/docs/unstable/misc/efi.html

So...

Where should I put the xen-4.2.2.efi and the corresponding config file into ? How should I configure the efibootmgr ?

Thanks.
