[one-users] OpenNebula 3.4 + Xen 3.4.4 + CentOS 5.8

One thing I noticed is the device_model definition - I'm not sure how to configure this in the one templates. Next it would be network. In the custom configs I've avoided the network config at this point (I don't seem to have that option in OpenNebula).
The enclosed config boots the CentOS LiveCD and a simple xvda image.
Here is an example of the local domain config:
# cat xen1.example.com.conf
import os, re
arch = os.uname()[4]
kernel = "/usr/lib/xen/boot/hvmloader"
builder='hvm'
memory = 512
shadow_memory = 8
name = "xen1.example.com"
vif = [ 'type=ioemu, bridge=eth0' ]
disk = [ 'file:/home/xen1.example.com.img,xvda,w', 'file:/home/CentOS-6.2-x86_64-LiveCD.iso,xvdc:cdrom,r' ]
device_model = '/usr/lib64/xen/bin/qemu-dm'
boot="dc"
sdl=0
vnc=1
vnclisten="0.0.0.0"
vncconsole=1
vncpasswd='howtoforge'
stdvga=0
serial='pty'
usbdevice='tablet'
on_poweroff = 'destroy'
on_reboot = 'restart'
on_crash = 'restart'
Thanks,
Marshall

Hi,
If you are successfully deploying the VMs directly, What are the differences between the domain configuration file you are using and that generated by OpenNebula (deployment.0)?
Cheers
Ruben
