Could you also post the output of "xenstore-ls -fp | grep target"
please.

You should have a directory /sys/devices/system/xen_memory/xen_memory0.
Please could you post the contents of each of the files in there. In
particular target*, *retry_count and info/*.

It might also be interesting to see the result of "xl debug-keys q"
followed by "xl dmesg".

Does "xl mem-set 0 4051" make the messages stop? If not what about using
4050?

If you try and balloon up to 4096 (with xl mem-set) does the amount of
memory in xl list change?
