Xen users - Jan 2006 - Guest is not able to mount root device

Hello!

I use Xen3 and Linux 2.6.15 from mercurial. I followed the steps in

   http://tx.downloads.xensource.com/downloads/docs/user

to install it.

Now I''ve the problem that after I issue

   cd /etc/xen; xm create ts (*)

the following error is raised:

--------------------------------------------------------------------------------
[9:52] klapperwachstum:xen# xm create ts
Using config file "ts".
Error: Device 0 (vif) could not be connected. Hotplug scripts not working.
--------------------------------------------------------------------------------

Now I list the VMs and see that it is paused:

--------------------------------------------------------------------------------
[9:52] klapperwachstum:xen# xm list
Name                              ID Mem(MiB) VCPUs State  Time(s)
Domain-0                           0       63     1 r-----  3011.4
ts                                34       64     1 --p---     0.0
--------------------------------------------------------------------------------

I connect to the domain using "xm console ts" and issue
"xm unpause ts" on another console (**).

The xend logs can be found at (***), the dmesg output and
config of the domain0 at (****) and the two .configs I tried
for the guest at (*****).

Do you have any hint for me, what I am doing wrong? The hotplug
package is installed on the host and I do not understand
how the "vif" network device problem relates to the root device
not found message (from guest console).

Oh, btw, "xm create -c ts" does not open a console.

Sincerly,

Nico

Btw, I found a difference to a xen2 patched kernel: The other
kernel hast messages about a xen block driver in its dmesg.

The 2.6.15 kernel I use does not have those messages.

Is the new kernel/patch more silent or is it missing?

Nico
