[geeks] OS testing, dragonfly

I don't know what's happening and it doesn't sound right, so I just
installed both the i386 and x86_64 CDs for 2.10.1 in VirtualBox to check.

In top I see both CPUs active on both architectures in my newly installed
VMs.

In /boot I have kernel and kernal.UP. .UP is the uniprocessor version. I
don't see a symlink but I do have an option to boot a normal kernel (in my
case SMP although called just "kernel") or a UP kernel in the Dfly boot
menu. Can you try to boot from the menu and select it?

Sounds to me like maybe you installed the wrong kernel and I don't know how
to change it but it should be trivial.

I saw you wrote this before but I don't understand what you mean. NetBSD is
missing SMP support for what? Virtualization? I ran SMP kernels on Net
years ago, I don't understand what you are saying. We are talking Intel/AMD
x86_64 right?
