Subject: [PATCH 5/6] hv: Enable vmbus driver for nested root partition
Date:   Wed,  2 Nov 2022 14:00:16 +0000

Currently VMBus driver is not initialized for root partition but we need
to enable the VMBus driver for nested root partition. This is required
to expose VMBus devices to the L2 guest in the nested setup.
