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@host ~]# cat /sys/devices/system/xen_memory/xen_memory0/info/current_kb
1048532
[root@host ~]# cat /sys/devices/system/xen_memory/xen_memory0/target_kb
1048576
 
Any ideas?
