when virt-manager is running, xenstored is taking a lot of cpu (which it shouldn't), guest systems are very slow, general usage of virt-manager feels very slow compared to earlier versions

launch virt-manager with xen 4.1.1

Steps to Reproduce:

Is this a regression compared to a previous virt-manager version, or is this your first time trying virt-manager?

We talked on IRC, Alexander ran a bisect and narrowed down the issue, and I pushed a fix!
