Description of problem:
This morning I have found my machine to be very slow and it seems xenstored is
the culprit. I have two active domUs so I paused them via virt-manager to see
if that would alleviate the problem but it doesn't seem to have made much
difference. System load is currently 4 and all disk I/O operations are very slow.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
The Linux domU is using LVM partitions, the other one is using file-backed
storage in /var/lib/xen/images
Known problem reported upstream:
Not aware of any current work to re-writing XenStored to not suck yet :-(
The performance problems are even worse in Xen 3.0.5
I am experimenting with ways to address it....
This report targets FC6, which is now end-of-life.
Please re-test against Fedora 7 or later, and if the issue persists, open a new bug.
