Running Server 2008 Core w/ Hyper-V RC0 on an HP Proliant ML350 G5, 4GB ram, 2ghz Quad Core Intel. Primary use for one of the virtual servers is a WDS server, it seems to function really well. Configured another virtual server, standard 2003 server. Having issues with displaying websites, in particular websites with alot of graphics on the page. i.e. www.microsoft.com Seems to hang the virtual machine everytime. However, I noticed that the system itself isnt actually hanging. If I click on the scroll bar and drag it or click on minimize it will perform the action but not display it on the screen. This happens for both RDC and Hyper-V screens, and on all Virtual Machines. Loading Windows screens and browsing around the local system is fine, the performance of the WDS server is fantastic. Difficult to explain, wondering if anyone else has experienced these issues.
