Migrating a VMware Windows 2019 to Proxmox using Veeam

[Jaques]

Hi all!

I'm trying to migrate a VMware Windows 2019 VM using Veeam from ESX to Proxmox.

Prior to making my final Veeam backup I've installed the Virtio tools. Took a full backup then restored to the new Proxmox host.

During the restore process I selected he host within Veeam, along with RAW storage. The VM restores correctly, but when I start it Windows kicks up an ACCESSIBLE BOOT DEVICE error.

Thanks in advance!

Wanted to add if I run this command after mounting the Virtio ISO I see the disks

>drvload vioscsi.inf

When I reboot and try listing disks from command prompt under Troubleshooting it doesn't see them.

Seems like the driver install isn't persistent.

Detach the disk, try changing the disk to SATA mode to see if it can boot, and don’t forget to modify the boot order.

>drvload vioscsi.inf

Yes AFAIK that only loads the driver - but doesn't install it to your Windows install.

I believe you need to use the dism command to actually install the drivers. See an example here through Windows Recovery.

Thanks everyone, it worked!

What worked for me was detaching and remounting as a SATA disk. Creating a small 1GB drive as SCSI which let Windows install the drivers.

I'm going to test this method on another VM shortly: https://hull.au/blog/install-virtio-drivers-from-windows-recovery/
