Hi Marco.
>disk = [
'file:/home/kpanic/xen-images/centos.img,sdb1,w','file:/home/kpanic/xen-images/centos-swap.img,sdb1,w'
]
It looks like both the centos.img and the centos-swap.img are being
exported as sdb1.
Here is an example of config parameters for a file backed domain.
name="bob"
memory = 128
kernel = "/boot/vmlinuz-2.6.11-xenU"
disk =
['file:/home/bob/centos.img,sda1,w','file:/home/bob/centos-swap.img,sda2,w']
root = "/dev/sda1 ro"

hi,
I followed http://mark.foster.cc/wiki/index.php/Centos-4_on_Xen and
populated the image with centos' packages downloaded from the net.
my config file in /etc/xen is centos, so /etc/xen/centos contains:
kernel = "/boot/vmlinuz-2.6.11-xenU"
memory = 96
name = "centos"
dhcp = "dhcp"
disk = [
'file:/home/kpanic/xen-images/centos.img,sdb1,w','file:/home/kpanic/xen-images/centos-swap.img,sdb1,w'
]
# or if you use LVM
# disk = [ 'phy:/dev/vg01/vol01,sdb1,w','phy:/dev/vg01/vol02,sdb2,w' ]
root = "/dev/sdb1 ro"
but when I try to:
# xm create -c centos
I obtain:
Using config file "/etc/xen/centos".
