Hi, I upgraded to Incus from 6.15 to 6.19.1 today and it now seems I can no longer share a disk between host and guest with a command like: incus config device add winvm workspace disk source=$PWD path=FOO Previously this would share the current host directory with the Windows VM appearing as Z:\ …

Ok, I set the VM instance config image.osto Windows incus config set winvm image.os Windows and all is working again now :grinning_face: Thanks @stgraber
