Transition can be done by using the convertor freely available from;


MS Virtual Server does not support Linux distrubitons apart from RHEL
and SuSE, officially. But you can manage to install and run **others**
with little more effort.

MS provides a package called VMAdditions that contains daemons. One is
addressed to time sync issues and it synchronises the time of the
guest machine with the host machine's.

I managed to work Centos5 and Slackware 10.2 on MS virtual server.
CentOS have to be installed in text mode.
