Hi all again,

I try other kernel and the problem continues.

My DomU.cfg:
name='ubuntu10.04'
memory=512
vcpus=2
disk=[
'tap2:tapdisk:aio:/PATH/ubuntu10.04/hda,hda,w',
'tap2:tapdisk:aio:/PATH/ubuntu10.04/xvda,xvda,w',
]
boot='c'
on_reboot='restart'
on_shutdown='destroy'
on_crash='destroy'

With the old kernel, 2.6.32.24, with pvdrivers (used this patch:
http://blog.alex.org.uk/tag/xen/ ) this VM boot OK.

I try kernels 2.6.36.1 and 2.6.37-rc4, and the problem continues:
blkfront: xvda: barriers enabled (tag)
 xvda: xvda1
vbd vbd-51712: 16 xlvbd_add at /local/domain/0/backend/vbd/470/51712

Build the new kernel does not seem to be able to view all disk partitions in
xvda disk (I have / on xvda1 and swap on xvda2) with raw disks (sparse). I
try vhd disks and problem continues. These disks contains the partition
table. The xen-blkfront have a problem with the disks right?

Could someone give me some more help?

Cheers,
Roberto Scudeller
