Jump to: navigation, search

Introduction

This is a set of best practices to follow when installing a Windows 8 guest on a Proxmox VE server 4.x. Right now it's a work in progress but hopefully soon it will be a comprehensive and reliable document. Please feel free to add to it, even if just to pose a potential best practice.

Install

Prepare

  • ​After clicking "Create VM" enter a Name: for your vm, select your Resource Pool (if you have one) and click Next
  • Select Microsoft Windows 8/2012 in the OS tab and click Next.
  • Select an ISO Image: for Windows 8 in the CD/DVD tab and click Next.
  • Select Bus/Device: VIRTIO, Storage: "your preferred storage" and Cache: Write back (the No cache default is safer, but slower) in the Hard Disk tab and click Next.
  • Select number of Sockets and cores (the default of 1 is mostly sufficient) in the CPU tab and click Next.
  • Select Automatically allocate memory and set the Maximum memory to a number you may require in the memory tab and click Next.
  • Select Model: VirtIO (paravirtualized) in the Network tab and click Next
  • Click finish and go to the Hardware tab of your newly created VM and click Add -> CD/DVD drive
  • Select Storage:local and ISO image: virtio-win-x.x.iso and click create.

Launch Windows install

  • Start your newly created virtual machine using the "Start" link in the upper right.
  • wait until the vm icon has turned white before you login using the "Console" link in the upper right. (NOTE: Sometimes the java console does not start at the first attempt. Please click refresh/reload in this case)​​
  • Start the server install with "Install Now" and click next and select "Custom (advanced)"
  • If you do not see "Drive 0 / Unallocated Space" click Load driver, browse to CD named CDROM and select folder WIN8\AMD64 and confirm. Select all three offered drivers (by pressing the CTRL button) "Red Hat VirtIO SCSI controller, Redhat VirtIO NIC and Red Hat Balloon driver" and click next.
  • Install Windows to "Drive 0 / Unallocated Space"
  • Wait until Windows is installed and select a Password for the local Administrator account and login to Windows.

Install additional VirtIO drivers

If you don´t got all virtio drivers selected on install, you can install them also later.

  • Start Explorer, Go to CDROM, copy folder WIN8\AMD64 to C:\Program Files\ and rename AMD64 to C:\Program Files\VirtIO
  • open Device Manager and right click on Other Devices -> Ethernet Controller and select update driver software
  • select "Browse my computer" select folder "C:\Program Files\VirtIO" and click "Install" for Red Hat VirtIO Ethernet Adapter.
  • again in Device Manager right click on Other Devices -> PCI Device and select update driver software
  • again "Browse my computer" select folder "C:\Program Files\VirtIO" and click "Install" for VirtIO Balloon Driver.

raw vs qcow2

Raw file format provides slightly better performance while qcow2 offers advanced features such as copy on write and Live_Snapshots. Since V2.3, qcow2 is the default format.

virtio drivers

Use virtio dirvers for best performance. More info: Paravirtualized Block Drivers for Windows
