I've never yet managed to build a booting vm with gentoo. Probably my own fault, but I don't want to wrangle and study and diddle around endlessly. Which appears to be what it takes for me anyway.
This is a i7 64 bit system using semi newish and common sata disks (WD 500GB [black]), and I don't need trick raid modules or the like, so should be easy enough to build a kernel for. ( Setup: QuadCore Intel i7 820QM, 2648 MHz (20 x 132) - 8GB ram) I've found that even a genkernel built kernel including the kitchen sink will fail to boot. Debian and Opensolaris installed in vbox vms with ease I don't want to keep wasting time building the basic OS, only to have it not boot. I'm not speaking from real recent experience so it probably wouldn't be much help to ask what error I'm having or such like. I just know from oft repeated attempts from time to time, that it will be a pita so would sooner just try a known working appliance ready made. In case you are thinking, I'm lazy... well yeah, somewhat... but I have put in extensive effort over time... Just want the easy route this time. (I'm also older than dirt .. hehe)
