Comment 5 for bug 429106

Fixing importance to High. It is not appropriate to use the host kernel for this purpose, as:

- It is the -server kernel, rather than the -virtual kernel (and this use case is exactly why -virtual was created)
- The instance could be 32-bit, while the host is 64-bit (this may in fact work, but is not correct)
- The host and image may be based on different versions of Ubuntu
- The host and image may have different kernel module ABIs

There are probably others, but suffice to say, this needs to be corrected.
