Due to performance limitations of Virtual PC 2007 and the additional resources required for Internet Explorer version 8 and later to function properly, it is not recommended to use any version greater than Internet Explorer 7 in the MED-V 1.0 Workspace.
Only Windows Internet Explorer 6 SP2 and Windows Internet Explorer 7 are officially supported for the MED-V 1.0 SP1 workspace installation. This is referenced on the following link:

For Version 2 of MED-V, Windows Internet Explorer 6, Windows Internet Explorer 7, Windows Internet Explorer 8, and Windows Internet Explorer 9 are supported for the MED-V 2.0 workspace installation.
