[Xen-users] xen 3.0.3

["Fong Vang" <sudoyang@xxxxxxxxx>]

I have several systems running Xen 3.0.2 on Fedora Core 5.

Today, I started playing with Xen 3.0.3 also on FC5.  dom0 starts up
fine without any problem.  However, I cannot create any domU's (domU =
CentOS 4.4).  This is the error being reported:


[root@xenmgt ~]# xm create -c meta
Using config file "/etc/xen/meta".
Error: Device 0 (vtpm) could not be connected. Backend device not found.




this is in xend-debug.log:

THe config file:

kernel = "/boot/xenkernel"
ramdisk = "/boot/xeninitrd"
memory = 512
name = "meta"
vif = [ 'mac=00:16:3e:00:14:12, bridge=xenbr0' ]
disk = [ 'phy:xenvg/metaroot,sda2,w', 'phy:xenvg/metausr,sda3,w',
'phy:xenvg/metavar,sda4,w', 'phy:xenvg/metaswap,sda5,w' ]
vtpm = [ 'instance=1,backend=0' ]
root = "/dev/sda2 ro"
extra = "3"


Any idea what's wrong.

thanks for any help.
