[Xen-devel] Linux mainstream balloon driver fails to grow memory= -> maxmem=

[Dan Magenheimer <dan.magenheimer@xxxxxxxxxx>]

Hi Jeremy --

Vasiliy discovered (and I confirmed) that the mainstream
Linux balloon driver won't balloon above the initial
memory with which the Linux guest was launched.  E.g.
a 2.6.34 guest launched with these in vm.cfg:

memory=1024
maxmem=1536

displays properly in xentop, but changing target_kb
in /sys/devices/system/xen_memory/xen_memory0
doesn't "take" for any value greater than 1024*1024.

We tested with 2.6.34 but it even fails in RHEL6 Beta2.

Is this a known problem/bug (or maybe a feature)?

Thanks,
Dan
