My /var/log/messages log is being flooded with kernel messages showing the following messages

Aug  1 11:22:52 host43 kernel: System RAM resource 48000000 - 4fffffff cannot be added
Aug  1 11:22:52 host43 kernel: xen_balloon: reserve_additional_memory: add_memory() failed: –17

Doing a search I found a thread from xen-devel that talks a bit about it.  I’m not sure if this is related to the same issue or if that issue was ever fixed.  When I cat current_kb and target_kb the values don’t match, they are just barely off.  I have not tried setting them to match yet.


[root at host ~]# cat /sys/devices/system/xen_memory/xen_memory0/info/current_kb
[root at host ~]# cat /sys/devices/system/xen_memory/xen_memory0/target_kb

Any ideas?
