Re: [Xen-users] XenU installs

Thanks Mark,

i tend to use Ubuntu for my dom0, but i want to try and virtualise as
many non-windows OSs as possible. ;)
i tried the following config:

kernel = "/boot/vmlinuz-FC6-install"
extra = "selinux=0 reiserfs"
memory = 128
name = "andre_test_01"
cpus = "1"
vif = [ 'bridge=xenbr0' ]
disk = [ 'file:/xendisks/andre_test.img,sda1,w',
'file:/xendisks/andre_test_swap.img,sda2,w' ]
root = "/dev/sda ro"
ramdisk = "/boot/initrd-FC6-install"
builder = 'linux'

but the FC installer couldn't find the "SCSI" disks.
i then changed the config to:

disk = [ 'file:/xendisks/andre_test.img,hda1,w',
'file:/xendisks/andre_test_swap.img,hda2,w' ]
root="/dev/hda1"

but the installer saw the images as different disks and not
partitions, so then i changed to:

disk = [ 'file:/xendisks/andre_test.img,hda,w',
'file:/xendisks/andre_test_swap.img,hdb,w' ]
root="/dev/hda"

the installer then made it through to installing the RPMs .... and then it died.
am i doing this correctly?
