Yeah, some other folks have suggested that too, but it looks like you need kernel version 2.6.18-199 or higher to run iotop, and CentOS 5.5 only has 2.6.18-192 or something... Guess I need to wait for the kernel to be updated there if I want to use iotop, which sounds like a very cool utility. -erich On Jan 5, 2011, at 1:35 PM, Javier Guerra Giraldez <javier@xxxxxxxxxxx> wrote: > On Tue, Jan 4, 2011 at 11:19 AM, Erich Weiler <bitscrubber@xxxxxxxxx> wrote: >> Thanks for replying! I was able to figure it out - it was not the fault of KVM. One of the guests was running ganglia gmetad which was updating 30,000+ rrd files every 15 seconds (thus generating load via disk I/O), I didn't spot that until shutting down the VMs one by one until I found the offending one. It was just a needle in a haystack. ;) > > i use iotop to check which VM is hitting the disk > > -- > Javier -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
