Subject: [PATCH] convert: windows: Online all virtio disks at first boot
|
||||||
|
|
||||||
|
Windows 2022 (and possibly earlier versions back to around 2019) will
|
||||||
|
force offline any non-boot disks which change bus, apparently as a
|
||||||
|
security mitigation. The effect of this is that although the system
|
||||||
|
drive (C:) is present after conversion, other drives may seem to
|
||||||
|
disappear.
|
||||||
|
|
||||||
|
Running a Powershell script to bring all disks online seems risky.
|
||||||
|
The compromise is to bring online only virtio disks at first boot.
|
||||||
|
|
||||||
|
To further reduce risk, we only do this if there are non-system disks
|
||||||
|
(ie. > 1 disks in total), and only if we installed virtio drivers.
