On Gen2 VMs, Hyper-V provides mmio space for framebuffer. This mmio address range is not useable for other PCI devices. Currently only efifb driver is using this range without reserving it from system. Therefore, vmbus driver reserves it before any other PCI device drivers start to request mmio addresses.
