[Xen-users] cant start more that one hvm domU on amd64 debian etch dom0


After having run successfully for some time on Debian AMD64 Edge and its
3.0.3-1 xen software on HP 385 DL computer paravirtualized domU's i  am
trying out to run also HVM domU's. It seems one HVM domU starts up and
runs all right but starting the second one bails out with such errors

bash# xm create /etc/xen/domU-hvm-2.sxp
Using config file "/etc/xen/domU-hvm-2.sxp".
Error: Device 768 (vbd) could not be connected. Backend device not found.


domid: 80
qemu: the number of cpus is 1
shared page at pfn:3ffff, mfn: 1ef810
buffered io page at pfn:3fffd, mfn: 1ef812
False I/O request ... in-service already: 0, pvalid: 0, port: 0, data:
0, count: 0, size: 0

My domU configuration files differ in location of images, mac address
and name

kernel = "/usr/lib/xen-3.0.3-1/boot/hvmloader"
builder = 'hvm'
device_model = '/usr/lib/xen-3.0.3-1/bin/qemu-dm'
memory  = '1024'
vcpus = '1'
vif = [ 'mac=00:16:3E:3A:9E:7A, type=ioemu, bridge=xenbr2' ]
disk = [ 'file:/data/domains/domU-hvm-2/disk.img,ioemu:hda,w' ]

Though computer has 2 x dual core cpu's i read it is adviced on debian
etch to configure one cpu into dom0 to make system more stable. In fact
it was unstable and this trick fixed it all right.

If you could shed some light on that issue i am not able to boot second
HVM domU it will be great!
