[Xen-users] pv-grub installation problem

[Aastha Mehta <aasthakm@xxxxxxxxx>]

Hello,

I am trying to install pv-grub for my guest domains and I am facing
some troubles with that. I followed the steps as provided on the wiki
- http://wiki.xen.org/wiki/PvGrub, or more like
http://backdrift.org/xen-pvgrub-howto

I tried to manually install the kernel packages in guest -
linux-headers-3.13.5-031305-generic_3.13.5-031305.201402221823_amd64.deb
linux-headers-3.13.5-031305_3.13.5-031305.201402221823_all.deb
linux-image-3.13.5-031305-generic_3.13.5-031305.201402221823_amd64.deb

sudo dpkg -i linux-header-*deb linux-image-*deb

and I get the following output:

(Reading database ... 24775 files and directories currently installed.)

There is no /boot/grub/device.map file. Also, I manually tried to
install grub on /dev/xvda2, but it gives me similar messages:
root@u3:~# grub-install --boot-directory=/ /dev/xvda2
/usr/sbin/grub-probe: warn: disk does not exist, so falling back to
partition device /dev/xvda2.
/usr/sbin/grub-setup: warn: disk does not exist, so falling back to
partition device /dev/xvda2.
/usr/sbin/grub-setup: error: cannot guess the root device. Specify the
option `--root-device'.
root@u3:~# mount
/dev/xvda2 on / type ext3 (rw,noatime,nodiratime,errors=remount-ro)

Clearly, the MBR is not properly set up. So, of course when I try to
boot the guest domain I get the "grubdom>" prompt, and I am not able
to boot.

Can somebody let me know what is going wrong and how I can fix it?

Thanks,
Aastha
