Hi

Were you using a working kernel config (with your VM) when compiling
your kernel ? Did you compile it on your VM or on your host OS ?

I use VirtualBox and Archlinux as a guest OS and never had a problem
when using a custom kernel.

What is the specific error you encounter when trying to boot ?
