[one-users] Cannot start VM with XEN

[anthony garnier]

Hi,

I've just installed openebula  and I can't create a VM.
I use Xen hypervisor 3.1.2

Frontend : one
CentOS 5.5 64bits

Node in cluster : node01
CentOS 5.5 64bits for Dom0
Debian lenny i386 for DomU

I can directly create a fully running Debian VM with xm cmd but when I use 
 # onevm create debian.one

# onevm list 
 ID     USER     NAME    STAT       CPU     MEM        HOSTNAME        TIME
 17     root        debian     fail             0        0K             node01          00 00:01:04


content of debian.one : 

NAME   = debian
CPU    = 1
MEMORY = 512

    OS     = [
       kernel   = "/boot/vmlinuz-2.6.26-2-686-bigmem",
       initrd   = "/boot/initrd.img-2.6.26-2-686-bigmem",
       root     = "xvda1" ]
#OS = [BOOTLOADER  = /usr/bin/pygrub]

    DISK   = [
       source   = "/opt/nebula/repo/debian.img",
       target   = "xvda1",
       readonly = "no",
       driver   = "file:"       ] # already tried to change into tap:aio

    DISK   = [
       type     = "swap",
       size     = 1024,
       target   = "xvda2"]

NIC    = [ NETWORK = network ]

This is the file when I create a VM manualy with xm on node01
name = "test-debian-install"
uuid = "ecc46d0d-95f2-8b0b-fe92-94f3391d58a5"
maxmem = 1024
memory = 1024
vcpus = 1
bootloader = "/usr/bin/pygrub"
on_poweroff = "destroy"
on_reboot = "restart"
on_crash = "restart"
disk = [ "tap:aio:/var/lib/xen/images/test-debian.img,xvda,w" ]
vif = [ "mac=00:16:36:68:56:ef,bridge=xenbr0,script=vif-bridge" ]



Does someone have a clue ?
