Windows VM Setup Guide

1. Host machine setup

We use the same CentOS 8 host setup as vm guide. Notice that PTP_KVM is not woking for Windows VM, IMTL uses VM system time by default.

1.1 Create Windows VM

# install if not
sudo yum install virt-install virt-viewer

# install virtio-win
sudo yum install -y virtio-win

sudo virt-install \
        --name win_vm0 \
        --vcpus 8 \
        --cpu host-passthrough \
        --ram 8192 \
        --memballoon none \
        --clock offset='localtime' \
        --network default \
        --disk /path_to_img/vm0.qcow2,size=20,bus=sata \
        --cdrom /path_to_img/windows_server_2022.iso \
        --boot cdrom,hd \
        --hostdev pci_0000_af_01_0 \
        --hostdev pci_0000_af_01_1 \
        --graphics vnc,listen=0.0.0.0,port=5901 \
        --video=qxl

The VFs created are passed into VM by specifying --hostdev pci_0000_xx_xx_x.

After running virt-install command, the viewer will pop up and you can normally install Windows in the GUI.

1.2 Setup remote desktop access

In virt-viewer window, logon to Windows, go to Start->Settings->System->Remote Desktop, set Enable Remote Desktop to On.

If you set --network default above, the VM should use NAT IP address for the network. You can map the VM RDP port to host.

# get the assigned IP
sudo virsh net-dhcp-leases default
# enable public access
sudo iptables -I FORWARD -m state -d 192.168.122.0/24 --state NEW,RELATED,ESTABLISHED -j ACCEPT
# RDP(3389) port forward
sudo iptables -t nat -I PREROUTING -p tcp --dport <public_port> -j DNAT --to $VM_IP:3389

On you local Windows PC, use Remote Desktop Connection or Remote Desktop (Store) to connect to [Host_IP]:<public_port>.

2. VM setup

2.1 Install virtio-win inside VM

Attach the iso drive to VM:

sudo virt-xml win_vm0 --add-device --disk /usr/share/virtio-win/virtio-win.iso,device=cdrom

In Windows VM, go to File Explorer->This PC->virtio-win, Click virtio-win-gt-x64.msi to install.

After the installation, you can detach the virtio iso and windows iso from cdrom in virt-manager.

2.2 Build and run IMTL

See Windows build guide and Windows run guide.

When installing netuio driver, use below command for iavf:

devcon.exe update netuio.inf "PCI\VEN_8086&DEV_1889"
