           Summary: Major corruption of Windows HVM disks - Xen 3.4
           Product: Xen
           Version: 3.0.4
          Platform: x86-64
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: HVM
        AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
        ReportedBy: adam.wilbraham@xxxxxxxxxxxxxxxx


I've come back into work after the weekend and noticed that all (3) of our
Windows HVMs have had massive issues with corruption of the hard disks. These
have all been running rock solid on Xen 3.2.1 for the past 9 months or so but I
upgraded their host to Xen 3.4 last week.

I noticed on Friday morning that all 3 had randomly rebooted on Thursday
evening but tried not to think too much of it.  Unfortunately as I say I have
come in this morning and they are all in various states of disrepair.

One VM is claiming ntloader.exe is not on the disk (presumably with a number of
other files), the other had crashed so I started it back up, it ran checkdsk
before running through lots of corrupt and missing files, rebooting and is now
BSODing on boot and the third boots but  has an event log full of SQL Server
errors talking about file corruption. As such I'm having to restore all three
from backups which is not ideal.

Has anyone experienced anything similar to this? Is it likely to be a problem
with qemu rather than Xen? Either way, I am left with no choice than to roll
back to a previous version of Xen as I cannot risk this happening again.
