I hope this in the right list, but I was wondering if someone could help me
with a VM I have that has lately started having problems. It had been
running for years without problems. It's possible an update is causing this,
but I can't say.

The VM is running CentOS 5.8 and after a time, the machine begins to slow
down. Things like pings or running commands lag. If I reboot the VM, it runs
normally for at least a few hours, but it eventually slows again.

I've tried changing the VM's virtio devices to standard devices like IDE and
e1000, but it makes no difference. Currently its running virtio.

Top shows that nothing is taking up significant cpu time, but even running
top takes several seconds for it to open. The system is slow now, but top
shows:

Any ideas what to look for? Any information I can provide?

Thanks
