Subject: [PATCH] v2v: windows convert: fix virtio block driver installation
|
|
|
90a56e |
for w10/w2k16

This patch fixes the problem of the first boot after installation virtio block
|
|
|
90a56e |
drivers on Windows 10 / Server 2016. The problem is related to the change in
|
|
|
90a56e |
the behavior of Windows-Kernel-Pnp. To fix we need to add a field "Version" to
|
|
|
90a56e |
HKLM/SYSTEM/DriverDatabase/DriverPackages/drv_inf_label then Windows-Kernel-Pnp
|
|
|
90a56e |
will be able to correctly install the virtio block driver.
