Xen Server 6.1 and virtualised Windows 2008 R2 Server

No,  using Xen Tools 6.0.2 patch 9 didn't solve the problem with the combo of Xen Server 6.1 and Windows 2008 R2 Server (frozen guest servers). Looking at announcements from Citrix and forum posts (and the lack of certain types of posts) it finally seems like Xen Tools 6.1 is patched to a working state (which will be tested). What might be working though is Xen Tools 6.1 with the <b>latest</b> patch and nothing else. Still problems with Windows Volume Shadow Copy though.
