Hi everyone.

I installed pkgsrc/sysutils/xen12 and pkgsrc/sysutils/xentools12, 
compiled a kernel from src/sys/arch/xen/GENERIC and xen12load from 
src/sys/arch/xen/stand and copied them to /grub/{xen-1.2.gz, 
xen12netbsd, and xen12load}.  Edited grub/menu.lst with the following 
entries:

    default 0
    timeout 5

    root (hd0,0,a)

     title NetBSD
        rootnoverify (hd0,0)
        chainloader +1

      title Xen / NetBSD
        kernel /grub/xen-1.2.gz dom0_mem=131072
        module /grub/xen12load root=/dev/wd0a
        module /grub/xen12netbsd

I am able to boot into Xen / NetBSD, but I am getting "dev/wd0a:  device 
busy" error messages during the boot sequence.  Did I miss a step(s) 
along the way?  Any help would be greatly appreciated. 

Here is the output from dmesg:
