I've never heard of the 'xforcevesa' option and don't expect virtual machines to use it either. The fallback path when a machine doesn't support 'modeset' is for Xorg to use the 'fbdev' driver. Never the 'vesa' driver because the kernel supports VESA BIOS Extensions using the fbdev API. So Xorg then uses 'fbdev' on VESA (BIOS Extensions) systems.

To actually *need* the Xorg vesa driver I think you would have:
 * A legacy BIOS, not EFI; and
 * An old kernel that doesn't have 'vesafb' to abstract VESA BIOS extensions into fbdev.
