Xen users - Mar 2007 - Q: domU booting problem: "XENBUS: Device with no driver"

Hi All,

I''m using SLES10SP1-b4 with kernel v2.6.16.37 and Xen v3.0.4. During
boot of a domU I see these messages:

...
XENBUS: Device with no driver: device/vbd/2049
XENBUS: Device with no driver: device/vbd/2050
XENBUS: Device with no driver: device/vif/0
XENBUS: Device with no driver: device/console/0
IP-Config: Device `eth0'' not found.
...

When I try to connect to the VM''s console with "xm console
<ID>" I only see the kernel boot messages, but not the messages
"init" produces. Although things improved after I manually load the
xennet driver in the domU''s /etc/modules.conf - at least the domU
configures eth0 with the xxx.yyy.zzz.191 address - , I still cannot connect to
the VM via network.

Just to make sure, my VM config is this:
# grep -v ^# /etc/xen/vm/xmsles | grep -v ''^ *$''
kernel  = "/boot/vmlinuz-2.6.16.37-0.23-xen"
ramdisk = "/boot/initrd-2.6.16.37-0.23-xen"
memory  = 512
name    = "xmsles"
builder = "linux"
vif     = [ ''mac=00:16:3e:08:a8:2e'', ]
disk    = [
''phy:vm/vm1,sda1,w'',''phy:vm/vm1swap,sda2,w''
]
root    = "/dev/sda1 ro"
dhcp    = "off"
netmask = "255.255.255.0"
gateway = "xxx.yyy.zzz.1"
ip      = " xxx.yyy.zzz.191"
extra   = "linuxrc=trace"

Btw: the initrd image does contain the xennet and xenblk modules.

So the question is: How to make these "Device with no driver" messages
disappear?
Thanks for your help.

Regards,
Gábor

Although running opensuse 10.2, I experienced a similar problem earlier 
this week. I could solve it by compiling xennet into the kernel instead 
of compiling it as a module and inserting it into the initrd.

See thread "[Xen-users] Installing a domU on NFS" from March, 8th.
