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

Hi All Back in August there was a report of these errors popping up in dmesg, and as far as I can tell it's still unresolved even in the latest kernel.

Hi, I am sending this e-mail once again because it probably has been lost in abyss of Xen-devel/LKLM list. Here is the second version of memory hotplug support for Xen guests patch. This one cleanly applies to git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git repository, xen/memory-hotplug head. Changes: - /sys/devices/system/memory/probe interface has been removed;

Hi Konrad, Today i tried linuses tree of today (last commit is 4c4d285ad5665bfbd983b95fde8d7a477d24a361). It boots dom0 fine, but it fails to start any domU with: "Error: Failed to query current memory allocation of dom0." With my previous 3.1.5 kernel everything is fine, nothing else changed in config in between. dmesg and xm dmesg attached -- Sander Dom0 shows: total
