Is it related to CPU, I/O, network? What does top say on the host? Is the VM consuming lo= ts of CPU all the time or generating an unusual high number of interrupts? VirtualBox tries to use hardware CPU features for virtualization BUT it als= o has a software emulation fallback (from QEMU I think) but that is painfully slo= w so usually when someone says "vbox is slow" that is a sign of either your CPU features weren't detected correctly or your BIOS has a bug and doesn't anno= unce them properly. In either case checking that you run the latest BIOS is a good idea. If you had a look at that stuff please attach your ~/VirtualBox VMs/Logs/VBox.log --=20 Bernhard Froehlich http://www.bluelife.at/
