Subject: xm sched-credit2 - changing weight of dom0 freezes machine
Date: Mon, 28 Mar 2011 00:30:08 -0700 [thread overview]
Message-ID: <4D903900.1020401@nuclearfallout.net> (raw)
In testing credit2, I have observed that changing the weight of dom0
freezes a machine on RELEASE-4.1.0. Executing this command immediately
causes a freeze, for instance:
xm sched-credit2 -d 0 -w 256
This is with the latest stable-2.6.32 (2.6.32.35-gdf3a556). I haven't
tested with credit2 previously, so I don't know how long this problem
has existed.
I also saw a different freeze event after starting up 20 or so domains
on one machine. There were no messages in the xend.log or
/var/log/messages after the freeze -- the machine just stopped
responding, as it does when trying to change the dom0 weight. How can I
effectively debug this if I see it happen again?
