Migration Driver selection

[Lucky Man]

Hi All,

I am trying to migrate from ESX to proxmxo
Some windows VM , using direct import or veeam backup restore without any issue
but some even i install the virto drive before migration, also cannot start up after migrate (Same Windows 2019)

have to detach and attach the disk to IDE, and SCSI controller using LSI, then can power on and enter OS properly.

any recommend for VM hardware config for migration, i think if each vm need to test the combination with hardware setting, will be a lot of work

Unfortunately you have to do it as you described. Windows only boots from virtio scsi when there already was a device installed using that driver.

There is a german post (with script) on how to inject the virtio scsi driver into windows before migration in a way windows can boot from virtio scsi immediately without the adding / removing and rebooting.

If you have some automation in place you may be able to run this in your VM's before migrating.
Then you can set your virtual controller directly to virtio scsi single and attach your virtual drives to that controller.

This most likely won't work on older Windows versions. Have not tested this myself.
