Public bug reported:

I installed Gutsy on a server (it was desktop Kubuntu). Updated all
packages using apt-get. Then installed xen using apt-get. I had a
Windows HVM up and running in a very short amount of time. I tried
copying a large database (~60gigs) to the Windows domU. After about 30
gigs transfered, the entire system locked up. No error messages to be
seen. I tried it again and the system locked up after transferring ~16
gigs. I tried this transfer several different ways.

- Database files located on remote linux box, exported drive using aoe
and handed the drive off to Windows domU using config file. Drive showed
up as expected and transfer started but crashed after several 10 gigs.

- Database files shared on remote Windows server. Windows domU accessed
remote server via smb and transfered database over network. Failed after
several 10 gigs.

- Database files on IDE drive connected to dom0 via USB-IDE adapter.
Handed off to domU using config file. Drive showed as expected, but
transfer cause dom0 lockup.

It seems like others have had this problem as well as discussed in the
xen-users mailing list (http://lists.xensource.com/archives/html/xen-
users/2008-04/msg00319.html)

I would like to help out in any way possible as I would like to continue
to use Ubuntu. I do not know where to begin or how I can help to get
more information. Please let me know what other information I may be
able to provide to help solve this problem.

Thanks,

Dan
