Created attachment 451044 [details] genkernal.log (additional attemtps did not seem to make any difference trying to install the latest gentoo under oracle virtual box on AMD cpu. The process has a couple errors. One in generating documentation. The serious one is it can't make/install bzImage. I also tried make menuconfig and mostly just took all the defaults except to turn off filesystems I do not plan on using, pretty much everything except the ext2, ext3, ext4 ones. I created a 20GB disk in the virtual machine with 17GB for /dev/sda1 and about 3.5GB for swap. I did not make a separate /boot partition. I was expecting the worst to be a boot failure when rebooting to the virtual hard disk. The page I'm following is at: https://wiki.gentoo.org/wiki/Handbook:AMD64/Full/Installation
I'm not sure that all the NAT involved would allow external ssh access. Teamviewer of one of the vnc flavors might work to my win7 machine where the VM's are.
If I understand thick bug ticket right, you had several problems with the installation and kernel generation in a virtual machine. I can not reproduce this or see a clear evidence of a bug in gentoo and we can not help you well with that problem in a bug tracker, so I will close this ticket. You will receive the best help in forums, mailing lists and on IRC. https://www.gentoo.org/support/ For a start you can try to install an IRC client like quassel and join #gentoo on freenode.
