Do you have VZU460004 update for Parallels Virtuozzo Containers 4.6 installed yet?  By the way, the Sysprep issue in your original question has been logged with our Dev team but you'll have to use your workaround for now
Hi all,  Wanted to ask around who is working with vWorkspace 7.2 joined with Parallels Virtuozzo 4.6 for Windows 2008 R2 ? Things are looking pretty cool with the Windows 7 skin and all, but I ran into an issue when creating a new group:  When I want to define a sysprep for my group, I create a Windows 2008 R2-based sysprep, but when I continue it claims that it want to see a Windows 2003-based sysprep. My guess would be that this comes from the previous vWorkspace version with Virtuozzo 4.5 which was largely based on Windows 2003. Is this all pretty new of is this a known issue and is there a workaround?
