(solved) Sluggish KVM machine - kjournald is 90+% CPU
*** EDIT *** Never mind - turns out turning on DMA really helps
Actually, I wonder why DMA wasn't automatically enabled? All of my debian/KVM machines have DMA as off....
Hi all,
Just a shot in the dark, but i have a debian KVM machine on my proxmox server running JIRA with a postgres backend and after a few days the machine gets really slow and kjournald is eating >90% CPU every few seconds - i.e. it will appear at the first line of top and then disappear and then a few seconds later it is back.

All thoughts/suggestions welcome.
