Subject: VMs crashing - Ubuntu 8.04, KVM84, libvirt 0.6.1
Date: Fri, 22 Jan 2010 11:26:14 +0000 (GMT)	[thread overview]
Message-ID: <141202443.974971264159574685.JavaMail.root@mail.thehumanjourney.net> (raw)

Hello list, 

I am using Ubuntu 8.04 with the kvm84 and libvirt 0.6.1 backports. I am experiencing regular crashes of my Vms - well, more like  "freezes" than actual crashes. This is how it looks like: http://waste.mandragor.org/kvmcpu/munin.html

* The VM keeps running
* The number of LOC IRQs goes down to 0, as well as the number of context switches
* The number of processes gradually grows
* The weird thing: some processes that were running before the crash keep running, but won't be able to fork (as you can see the munin-node continues to work)

This is bothering me a lot and I have absolutely no idea how to fix it or work around it. 
Has this been experienced by anyone else, and/or fixed in a later version of KVM?
