Comment # 4 on bug 1046571 from Larry Finger

With some creative usage, I was able to test the host modules on a 32-bit TW
guest. As both host and guest kmp packages cannot be installed at the same
time, the trick is install the host modules, which removes the guest module
package, but do not reboot the VM until the guest module package is restored.

I think it is safe to close this bug report.
