Re: [Xen-users] Xen must be on a 2Mb boundary

Hello,

I see "All files are in the same
sub directory of the ESP."

https://wiki.xenproject.org/wiki/Xen_EFI

As noted above, you might try with efibootmgr to make a menu entry in the EFI bios. I think this is a simpler approach than chain loading via grub.

Are you using the Xen rpms from distro, or did you build from source? I have a spec and SRPM from xen-4.7 & fc25 that should work with xen-4.8, but have not done that particular build yet.

My grub2 stanza is:

menuentry "Xen EFI" --class os {
    insmod part_gpt
    insmod search_fs_uuid
    insmod chain
    set root='hd0,gpt8'
    chainloader (hd0,gpt8)/EFI/fedora/xen-4.8.0.efi
}

and my xen.cfg is:

default=fedora
chain=grub.cfg

I've tried xen.cfg w/o the extra kernel 4.x stanzas. All files are in the same
sub directory of the ESP.

Anybody have any ideas? Thx.
