Comment 2 for bug 1891251

I have verified with Ubuntu 18.04.5 & MAAS versions 2.4.2, 2.6.2, 2.7, 2.8 and the same issue happened on MAAS. Its failing to configure grup and boot loader with disk type as virtio.

But the deployment was working 3 weeks back with ubuntu 18.04.4 and MAAS version 2.4.2 with KVM for disk type as virtio. I am not sure what happened suddenly to break this deployment functionality with disk type as "virtio" this virtio driver is required to boost the performance in the kvm environment rather to have disk type as IDE/SATA/SCSI
