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
