I've just pushed a commit that seems to fix this problem for me:


Without this commit, I see the behaviour you describe: a lockup after "Loading 
ipxe.lkrn...ready" when VT-x/AMD-V is enabled.

With the latest iPXE, I am able to successfully load ipxe.iso in VirtualBox 
even with VT-x/AMD-V enabled.

Please let me know if this fix works for you.
