How may I check the status of this issue? Is there a status available to the public?
I just loaded 2.2.4-47978 on a Windows Server 2008 64-bit host on an Intel quad core whitebox with 8Gb of memory. The hardware support for virtualization is enabled in the BIOS. I'll test with this disabled in the client and/or host this evening. XP seems extremely slow as a guest. I just happened to be loading XP on an old P4 physical machine for someone and it performed so much faster than the VM in VirtualBox on WS2008. Looking at the performance tab on the WS2008 host, it appeared that one processor core was much more heavily used than the other three.
