Subject: [Qemu-devel] VM stops responding, 100% CPU, switching to monitor fails
Date: Tue, 03 Feb 2009 13:10:08 +0000	[thread overview]
Message-ID: <1233666609.5644.12.camel@ecrins.fosdick.home.net> (raw)

I am currently experiencing an issue where the guest VM stops
responding, attempting to switch to the monitor does not do anything
either and the host CPU usage shows as 100% system.

So far the only solution I have found is to kill the qemu process.  A
normal SIGTERM signal seems to be sufficient.

This is with kernel 2.6.28.2, kqmeu 1.3.0~pre11 and qemu 0.9.1.

Do you have any tips on what I can do to get to the bottom of this?

I am thinking as the CPU usage is all system time that there maybe an
infinite loop running within kqemu though I would not know if the loop
was in code that is part of kqemu itself or the guest OS.  If the guest
had got stuck in an infinite loop though I would have hoped the monitor
would still work.

Regards,
Steve.
