Xen users - Sep 2005 - Domain creation error: ''No such file or directory''

All,

I''m using the latest Xen-unstable on a Debian 3.1 system.  I am able to
create a single domain alright with the following command:

xm create  name="vnode20" kernel="/boot/vmlinuz-2.6-xenU"
memory=128
disk=''file:/root/xen/run/vnode20_deb3.1_1.img,sda1,w''
disk=''file:/root/xen/run/vnode20_swap32.swp,sda2,w''
root="/dev/sda1 rw"
restart="onreboot"

But any attempt to create a subsequent domains fails with the error:

xm create  name="vnode21" kernel="/boot/vmlinuz-2.6-xenU"
memory=128
disk=''file:/root/xen/run/vnode21_deb3.1_1.img,sda1,w''
disk=''file:/root/xen/run/vnode21_swap32.swp,sda2,w''
root="/dev/sda1 rw"
restart="onreboot"
Using config file "/etc/xen/xmdefconfig".
Error: Error creating domain: (2, ''No such file or directory'')

(Note that /etc/xen/xmdefconfig is blank as I want to grab all the
parameters from the command line)

Has anyone seen this or know what could be causing the problem?

TIA.

Mike

Yes, this has been observed in several places and would seem to be a
genuine bug.

I am seeing this problem on my attempt at creating the first guest
domain on a PAE enabled SLES 9 SP2 box with 4GB of RAM. I am not seeing
it, however, on other boxes with less memory, PAE enabled and
disabled.

Hmm... it seems that decreasing dom0''s memory semi-fixed the problem. 
I
was able to create 4 domains instead of just 1 when I put dom0_mem=128M
as a xen boot parameter.  I still got the error message upon trying to
create my 5th domain though.
