Reboot Problem with virtio-scsi


Oct 24, 2016

I'm installed windows server on a vm with Virtio SCSI disk controller.
When I first power on vm all of things are OK, but when I take soft reboot on windows, seabios cannot boot again from virtio disk & vm reboot suddenly.
I should stop VM & start it again to boot from virtio disk & start windows.
I'm tested it with Windows Server 2008 & 2016, Also tested with stable & latest version of virtio drivers.
