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.
