AW: [Xen-users] Problems creating hvm guest after dom0 reboot

["Daniel Schmitz" <xen@xxxxxxxxxxxxxxxxxxx>]

Hi, 

does nobody has an idea? Or is everything correct and xen does strange
things? Maybe a restart of xen can help?

I even tried to start a hvm minimal guest, build with the example
configuration resulting in the same problem.

Greetings Daniel

Betreff: [Xen-users] Problems creating hvm guest after dom0 reboot

Hi,

I have some trouble to create hvm machines. Xen just tell me that the domain
creation failed:

# xm create /etc/xen/xenwin2008
Using config file "/etc/xen/xenwin2008".
Error: Creating domain failed: name=xenwin2008

The last time i had this error there was some trouble with ne vif line, but
the configuration worked perfectly until I had to restart my system (and
change the netmask of the eth0 interface from 255.255.255.248 to 240. But
that should not be a problem for xen?).

here is my configuration:

import os, re
arch = os.uname()[4]
if re.search('64', arch):
    arch_libdir = 'lib64'
else:
    arch_libdir = 'lib'

kernel = "/usr/lib/xen-3.2-1/boot/hvmloader"
builder='hvm'
memory = 1600
extid=0
stdvga=0

# Should be at least 2KB per MB of domain memory, plus a few MB per vcpu.
shadow_memory = 8
name = "xenwin2008"
vif = [ 'type=ioemu, bridge=eth0' ]
acpi = 1
apic = 1
disk = [ 'file:/.../xenwin2008.img,hda,w',
'file:/some.win.2k8.iso,hdc:cdrom,r' ]

device_model = '/usr/' + arch_libdir + '/xen-3.2-1/bin/qemu-dm'

boot="dc"
vnc=1
vnclisten = 'aaa.aaa.aaa.aaa'
vncunused=0
vncpasswd='somepasswort'


the files /usr/lib/xen-3.2-1/boot/hvmloader and
usr/lib64/xen-3.2-1/bin/qemu-dm are present.

I think the network settings are ok:
# brctl show
bridge name     bridge id               STP enabled     interfaces
eth0            8000.00304863b6a2       no              peth0

and here is the output of the xend logfile:

I'm looking forward to your suggestions.
