So I installed my first KVM guest image (a prerelease of Ubuntu 9.10 that I had lying around) this morning (through virt-manager, as it happens). Everything worked fine, the install was searingly fast compared to the UML virtual machines I'm used to. I got back to it this evening, restarted the VM, and found that it had suddenly slowed right down again, with one CPU being saturated with work even when nothing was happening.
