Hi, VirtualBox now works with VT and I'm able to run SMP guests! But apparently it's not very stable (got two boot crashes) and something is wrong with timers: Example 1: host HZ=250, guest HZ=1000, - guest time apparently speeds up more than it should Example 2: same host, guest HZ=100 - guest time apparently goes 5x slower than real (wall) time. Example 3: same host, guest HZ=25, guest time apparently 2x slower than real (wall) time. In the examples, host is amd64 8-BETA2, 4CPU, guest is 7.2-RELEASE i386, 2CPU. Internally the time is always consistent - for example in the second case "time sleep 2" says the guest slept 2 seconds, while in real time, 10 seconds have passed. Time apparently goes normal when the guest is configured with only one CPU (and VT is still active).
