Hello List!

I have crated my configration file (suse_xen.cfg) for creating a Xen Guest

kernel='/boot/vmlinuz-xen'
ramdisk='/boot/initrd-xen'
name='suse'
builder='linux'
memory=1024
maxmem=1024
root='/dev/xvda1'
disk=['phy:/dev/VolGroup00/suse_xen,xvda,w']
vfb=['type=vnc,vncdisplay=1,vnclisten=127.0.0.1']
on_shutdown='destroy'
on_reboot='destroy'
on_crash='destroy'
vcpus=1

Then I do

xm create -c suse_xen.cfg

although my Guest does not totally start.

I look for messages and have many errors like this

"(XEN) mm.c:645:d1 Non-privileged (1) attempt to map I/O space 00000000"

Can please someone say what I am not doing well?

Those messages are generally deemed harmless, and can (for the most part) be
safely ignored.
