[Xen-devel] Anyone using whole disks in domU?

[Jeremy Katz <katzj@xxxxxxxxxx>]

Anyone using whole disks in a domU?  When trying to do so here, I'm
getting a hang when doing the partition check and before I spend too
much longer staring at things, I'm wondering if anyone else has even
tried recently.  It looks like we're stuck waiting on something from
xenbus, but I'm not seeing it at this point before a holiday weekend.

Thanks to sysrq-t being available...
