VMWare Player is free, as is now VMWare server. With the Intel 
virtualization hardware, Xen will be able to run native Linux 
distributions, so it will also compete.

The 6.7.18 release includes code for an "outer" startd to update an 
"inner" startd, where the outer startd would run on the host operating
system and the inner startd is running on a guest VM operating system,
to do exactly what you describe. It's not documented, and I'm not sure if
there's more to do in 6.7.19 before it works, or if it will work once we
get the documentation out there. Either way, you should upgrade to 6.7.18 :)
