I have a dual-boot VM on XenServer 6.0.2 but grub just shows up as a black screen. I can still make a selection and such, but it's just a black screen in the XenServer console. Any ideas on how to make this visible?

After further research, it looks like this is related to a bug in XenServer Bug 30978
The temporary solution I have found is based on a suggestion within the bug comments. It looks like the workaround requires you to switch grub to console mode.
