Hello,
I have a 64 bit dom0 with RHEL5

I have a 32 bit domU para virtualized

I want to bring it on my new dom0

so I installed a non xen kernel on the domU
and I copyed the image file on hte dom0

I changed the /etc/xen/myhost accordingly

but when I start the domain it hangs and nothing happens

here is

/etc/xen/sympa5_3_2

name = "sympa5_3_2"
builder = "hvm"
memory = "1024"
disk = [ 'file:/xen/domU/sympa5_3_2,hda,w', ]
vif = [ 'mac=00:16:3e:3f:a9:f5, bridge=xenbr1', ]
vfb = ["type=vnc,vncunused=1"]
uuid = "ffc68565-354a-32da-7302-72a1bd5ff1af"
device_model = "/usr/lib/xen/bin/qemu-dm"
kernel = "/usr/lib/xen/boot/hvmloader"
vcpus=1
on_reboot   = 'restart'
on_crash    = 'restart'


I Also took a qemu-dm and used it insted of the default one which is 64bit

[root@xenserver2 xen]# xm create /etc/xen/sympa5_3_2 -c
Using config file "/etc/xen/sympa5_3_2".


nothing happens:
[root@xenserver2 ~]# xm list
Name                                      ID Mem(MiB) VCPUs State   Time(s)
Domain-0                                   0     2976     4 r-----    605.2
sympa5_3_2                                10     1030     1 --p---      0.0

[root@xenserver2 ~]# xm unpause sympa5_3_2

[root@xenserver2 ~]# xm list
Name                                      ID Mem(MiB) VCPUs State   Time(s)
Domain-0                                   0     2976     4 r-----    605.5
sympa5_3_2                                10     1030     1 ------      0.0

bit nothing happens.

para virtualized on my new 64 bit xen fully virtualized dom0 ?

thanks a lot

Rick
