I have a (32-bit) Windows XP guest installed, and if I start kvm-82
(from the Debian packages) on a 2.6.29-rc1 kernel (running 64-bit on an
AMD host), the guest boots but soon dies with messages along the lines
of:
lsi_scsi: error: Unimplemented message 0x0c
lsi_scsi: error: Reselect with pending DMA
scsi-disk: Tag 0x0 already in use
scsi-disk: Unsupported command length, command f0
lsi_scsi: error: Unimplemented message 0x0c
lsi_scsi: error: Reselect with pending DMA
scsi-disk: Unsupported command length, command f0
lsi_scsi: error: Reselect with pending DMA
scsi-disk: Bad buffer tag 0x0
Is this a known problem?

Can you reproduce with the kvm release rather than debian packages? I've
not seen this string of errors before.

Indeed, it appears the Debian package's security/CVE-2007-5730.patch
patch causes the failure; the patch seems to be identical to
http://cvs.fedora.redhat.com/viewvc/devel/kvm/kvm-62-block-rw-range-check.patch?revision=1.7&view=markup
I haven't tried to debug what the issue is yet.
