As I believe Microsoft and Redhat have some sort of co-support agreement with respect to each other's virtualisation platforms, you may want to report it on Redhat's bugzilla (after verifying that the fault is also present in the RHEL6 beta). I'd guess they'll either implement a workaround or have some relatively straightforward mechanism to report the fault to Microsoft - courtesy of their co-support agreement...
