Freenas Virtio Drivers

Mar 09, 2018  Even if I left Windows idling at the desktop, eventually it would just crash. I did try to install all of the VirtIO drivers, but it would still crash no matter what. Then I tried in FreeNAS 11.1-U1 and Windows 7/8/10 would just freeze during the installation at various percentages or steps.

Contents • • • • • • • • • Introduction In order to improve disk performance, special paravirtualized block drivers can be installed in Windows guests. You have to download and install those drivers in the VM, as Windows does not provides them by default. Note: Proxmox recommends using SCSI with VirtIO SCSI as SCSI Controller Type for VM disks, to have the most features and best performance. VirtIO block may get deprecated in the future. Download You can download the latest stable Windows VirtIO drivers from: Older Windows Versions may sometimes need older VirtIO drivers. See for more info about the change log, guest OS compatibility and other useful VirtIO guest devices. Upload the ISO through the Proxmox VE WebUI: Select a Storage which allows ISO images in the PVE WebUI and switch to Content tab where you can use the 'upload' button on the menu bar.

You may also copy the ISO manually onto a PVE configured storage. Installation The goal to use VirtIO SCSI or Block (SCSI is recommended) to improve the performance and available features of (Windows) VMs. The way we do this depends if we want to change an already installed and running Windows VM or if we want to set this up during a Windows installation.

Setup On Running Windows Here we add a temporary disk with the new wanted disk controller to the VM and install the respective drivers. The Windows OS in your VM knows nothing about VirtIO drivers, so you can't simply stop the VM, change the disk to Vrtio-SCSI or VirtIO and reboot.

You have to force Windows to install VirtIO drivers during it runs. To do this we add a small temporary SCSI-VirtIO or VirtIO disk to the VM and install its drivers explicitly. Without adding the Disk the installation of the driver is flawed under Windows, as driver installation of an not plugged in Hardware does not works. Tested guest OS • Windows 2003 r2 32 bit guest • Windows 2000 server sp4 • Windows 7 and newer should work • Windows Server 2008 and newer should work Setup Steps • Prerequisite: An installed running Windows OS and the • insert the VirtIO ISO into the VMs CDROM Drive. • add a small (1GB) SCSI (with Options -> SCSI Controller Typ: VirtIO) or VirtIO Block disk to the VM, you can use the PVE WebUI.

( Legacy Note: Windows 2000 may report each disk 8 times in disk management, just install and use the first of each 8-tuple. In 'My computer' you should see each disk only once.) Windows has now the VirtIO SCSI/Block driver installed, and we need to re attach the VM disks as SCSI or virtio.
