If you want another db commands running let me know - I'll leave this VM 'as is' for now. The underlying host is a SuperMicro X9SCL(+)/X9SCM w/8Gb of RAM, and an Intel 1220Lv2 CPU - running Windows Server Hyper V 2012. I checked out the hyperv source with SVN onto a FreeBSD 9.2-RC3 system, successfully ran 'make buildworld' and 'make buildkernel' - then installed the kernel. This is after the first reboot (i.e. beyond which you'd usually go to single user and do all the mergemaster/make installworld stuff). The VM was created using 4 CPU's and given 2Gb of RAM and a 30Gb IDE hard drive (at controller 0, location 0). If you need any more info or anything, please let me know, Regards, -Karl
