Xen users - Jan 2014 - Using XEN 4.1 to run Windows 7 DOMU on SERVER1, replicated the HVM to SERVER2 using DRBD. Win7 DOMU doesn't boot in SERVER2 after replication

Hi All,

I'm new to XEN and using XEN 4.1 on UBUNTU to run Win7 guest.

I've 2 Servers(both UBUNTU 12), where Server1 is configured with full Win7
guest installation on a partition(It works fine).

Now as i use DRBD to replicate this partition into Server2 system and try
to boot the Win7 DOMU from harddisk, I get below mentioned error -
Windows failed to start. A recent hardware or software change might be the
cause. to fix the problem:
1. Insert your Windows installation disc and restart your computer.
2. Choose your language settings, and then click "Next."
3. Click "Repair your computer."

Status : 0xc000000e
Info: The boot selection failed because a required device is inaccessible.

Find the below the XEN and DRBD configuration file

As the partitions created in both servers are by gparted and the start and
end address of the same are different. But the over all size of the
partitions for guest are same ie, 30 GB

Can anyone help me with booting the Win7 in Server2?


Thanks in advance
