OK, I installed both version 60 of both kvm and kvm-source (Debian Lenny), ran m-a a-i kvm and just to be sure I removed and reloaded the kvm and kvm-amd modules. modinfo kvm and modinfo kvm-amd shows that these are indeed version 60. I then restarted the guest (which is exactly the same as before) and I tried the 'sleep 10' test again. Same result: It takes about 17 or 18 seconds for the prompt to return again. I assume that clocksource=tsc isn't useful as it is already using the tsc. So, what else can I try? Any command line parameter I can add to the kvm call? Kernel parameters in the guest? Update the guest OS to a newer kernel (2.6.22 to 2.6.24)? Update the host OS to a newer kernel (2.6.23 to 2.6.24)? Thanks for the help!
