Title:
Hi,
Thought I'd mention that I'm having this problem too. The kernel logs are
flooded with this error:
ubuntu kernel: [129626.648070] xen:balloon: reserve_additional_memory:
add_memory() failed: -17
I'm running XEN on a dedicated i5 PC with Jaunty with up to date packages.
I haven't installed
