Windows – Can you install Ubuntu Server in a Windows PC VM on Windows 7

If the VM was already created, and you've simply copied it to a new machine, it's likely to still be counting down on it's 30 day activation limit.

You can either attempt to do a rearm of the trial period (not sure if this works in Server 2003). Follow the guide here for (Windows 7): http://windowssecrets.com/2009/08/20/01-Use-any-version-of-Windows-7-free-for-120-days

OR

An alternate work-around for this could be to disable the Time Synchronization between the virtual machine and the host machine. This way it can remain at a valid date inside the 30 day limit: http://blogs.msdn.com/virtual_pc_guy/archive/2007/11/28/disabling-time-synchronization-under-virtual-pc-2007.aspx

A very easy way of getting SUSE 11 up and going on a virtual machine is just download one of the pre made appliances that are offered. You can find several of them here. Once you download the correct version, you would just need to make a new virtual machine and point that virtual machine to the directory containing the downloaded virtual's hard drive.

Good luck, and hope this helps some.
