Subject: Linux mainstream balloon driver fails to grow memory= -> maxmem=
Date: Mon, 23 Aug 2010 16:49:26 -0700 (PDT) [thread overview]
Message-ID: <a8aa7cb8-1f20-44ec-a6d5-72e991b0bb6f@default> (raw)
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
