[Xen-devel] Problems booting VM using unified Xen kernel

["David F. Barrera" <dfbp@xxxxxxxxxx>]

I am having trouble booting a guest domain using the unified Xen kernel (it
works fine when using the XenU kernel). Whenever I try to create the domain, I 
get
the following message: 

bl2-1:/tmp/xen # xm create -c vm1.cfg
Using config file "vm1.cfg".
Error: (9, 'Bad file descriptor')


---------------------------------
The build was done using 'make world' and 'make install', and there were no
build errors:

Xen version 3.0-unstable (root@xxxxxxxxxxxxxxxxxx 
<mailto:root@xxxxxxxxxxxxxxxxxx>) (gcc version 3.3.3 (SuSE
Linux)) Wed May  3 14:23:44 CDT 2006

'strace' shows that files are missing:

----------------------------------------

domU config file:

kernel = "/boot/vmlinuz-2.6-xen"
# Optional ramdisk.
ramdisk = "/boot/initrd-2.6.16-xen"
# The domain build function. Default is 'linux'.
builder='linux'
# Initial memory allocation (in megabytes) for the new domain.
memory = 256
# A name for your domain. All domains must have different names.
name = "vm1"
disk = [ 'phy:sdb3,0813,w','phy:sdb2,0812,w' ]
# Set if you want dhcp to allocate the IP address.
# vif = [ 'mac= AA:00:00:47:CB:34, bridge=xen-br0' ]
vif = [ '' ]
# Set root device.
root = "/dev/sdb3 ro"
