I tried to setup Xen by the instruction released on the site of my hoster.
I installed Xen, completed RAID setup as it is told in the instruction. Rebooted and succesfully connected to Xen from XenCenter. Then I created a volume for ISO and added some images to it. Up to this point everything was OK. But then I rebooted again - and it didn't boot! The boot from disk doesn't start because it can't find bootloader.
I checked with mdadm status of raid - all partition are active.
How can I fix it?
