Re: [Xen-devel] Failure to setup Xen 3.4.1 Dom0 on top of Ubuntu 9.10 Server HVM DomU ( 2.6.30.2 xenified kernel)

[Boris Derzhavets <bderzhavets@xxxxxxxxx>]

  I've got same problems after setup Xen 3.4.1 Xen Dom0 ( with 2.6.31-rc5 pvops) on
top of Ubuntu 9.10 Server,had been installed on bare metal.

   It appears to be known issue with Grub2 when loading Xen host and came up
already on Debian Lenny.

 In case of Ubuntu 9.10 Server Xen host loading started and dropped to grub prompt
after gave up waiting for root device.

menuentry "Xen 3.4.1 Ubuntu 9.10"  {
set root (hd0,1)
multiboot (hd0,1)/xen-3.4.gz
module    (hd0,1)/vmlinuz-2.6.30.2 root=/dev/sda2 ro console=tty0
module    (hd0,1)/initrd-2..6.30.2.img
}

generated via /etc/grub.d/40_custom editing and running update-grub

Directive "root=UUID=...." switched off via editing /etc/default/grub and update-grub
run.
Seems to be Grub2's  multiboot implementation issue.
Grub2 breaks backward compatibility in meantime per my opinion.
Please, advise if i am wrong about that.

Karmic Server HVM DomU setup at Xen 3.4.1 Dom0 F11 via virt-install.
Attempt to build Xen from source and xenified kernel succeeded..
Before creating Grub 2 entry for Xen Host directive "root=UUID=.."  switched off by editing /etc/default/grub and update-grub run.

Manually created entry /boot/grub/grib.cfg as advised for Debian (Grub 2)
 
 Xen 3.4.1 Ubuntu 9.10 {
multiboot (hd0,1)/xen-3.4.gz
module    (hd0,1)/vmlinuz-2.6.30.2 root=/dev/sda2 ro console=tty0
module    (hd0,1)/initrd-2.6.30.2.img
}

Failure when waiting for /dev/sda2 and dropping to grub prompt

HVM itself loads fine.

Boris.
