Hi Robert,
I've only been using xen in FC5 for a few days and haven't had time to
play around much so I'm not familiar with the new scripts. I created my
config files manually and just copied the domU's across along with the
kernel image.
My DomU's are file based because they do little IO and I find them
easier to manage this way. I did convert one to LVM just to check it
worked, and if I ever need the IO performance I'll take this route.
In case it helps, my domU xen configs look like (I've got two bridged
nics setup):
kernel ="/boot/vmlinuz-2.6.12.6-xen3_12.1_fc4"
memory = 128
name = "xendev"
vcpus = 2
vif = [ 'mac=FE:FD:25:63:74:49,bridge=xenbr0',
'mac=FE:FD:3D:49:28:26,bridge=xenbr1' ]
disk = ['file:/xenimages/xendev.img,sda1,w']
root = "/dev/sda1"
extra = "ro selinux=0 3"
Matt.
