I love Ubuntu, especially when I wanted to work with python programming, But I also love windows 10 because of its GUI and the vast variety of software support.

In the last blog, I covered how you can install windows 10 on Centos/Redhat KVM. But in this tutorial I going to cover the Debian derivative Ubuntu.

Since I get a lot of questions with regards to Ubuntu specifically I decided to write separate blogs for Ubuntu and Redhat, so if you are using Centos/Redhat/Fedora you may click here.

I hope you are using the Ubuntu version of Linux so let’s get started.

Prerequisite.

Ubuntu machine with good configuration.
Download the Windows ISO image by following the guide here.
Windows virtio drivers iso download latest.
Download Spice guest tools.

Steps to install windows 10 in Ubuntu KVM.

Below is the video, if you prefer to watch over video.

1. Preparing the environment.

In my PC i am using Ubuntu version 20.04 so enter the below commands to install KVM on ubuntu machine.

sudo apt update
sudo apt install qemu-kvm bridge-utils virt-manager libosinfo-bin -y

You may now go ahead and reboot the host, if you dont reboot the machine then you will end getting a below error.

Unable to connect to libvirt qemu:///system.
Verify that the libvirtd daemon is running

2. Open the virtualization manager and create the VM.

Open terminal and type virt-manager

In the virtual machine manager window click on create a new virtual machine.

qemu windows install

A new window now will pop up. In the New VM wizard select Local install media and click on forward.

You will now have to browse for the windows 10 iso that you have downloaded and Uncheck the option which says automatically detect from the installation media.

Start searching for the window10 under choose operating system, and check the box which says include end of life operating system. Once you check the box you will be able to see the Microsoft Windows 10 operating system in the list.

Once you select the Microsoft Windows 10 click on forward.

2. Configure the virtual machine resources.

Next, you will be asked to define the memory and the CPU, I am giving 4GB of memory and 2 CPU’s and click on forward.

Depends on your configuration you may choose yours.

When you configure the virtual hard disk, by default Ubuntu KVM would pick up 40GB, since I don’t require that much space I just added only 20GB and clicked forward.

You may choose 40GB or more.

Finally, you will have to Name the windows KVM VM and check the option Customize configuration before install.

I also selected the network as Virtual network ‘default’ NAT. By selecting this network you guest VM will start using the Ubuntu host internet connection.

Click on Finish at this moment now.

3. Configure the virtual Hardware’s.

Since you selected customize option you will now be presented with the KVM customization screen.

Do not click on Begin installation yet, before that we have to modify some hardware changes.

Click on the SATA Disk1 , and on the right side expand the advanced options and click on the Disk bus drop-down list.

Select VirtIO as the disk bus, and then click on Apply.

You now have to add VNC Viewer as the graphics, so click on Add hardware from the bottom left.

In the add New virtual hardware windows, select Graphics and in the Type select VNC Server and click on Finish.

Click on Network interface card (NIC), change the device model to VirtIO, and click on Apply.

4. Add the Windows 10 virt drivers and configure the boot loader.

Remember that we have downloaded VirtIO Windows drivers for Ubuntu KVM, let’s attach that now. So click on Add hardware.

Select the storage and click on manage and attach the VirtIO iso file that we have downloaded, and also change the Disk type to CDROM device and click on Finish.

Change the boot order for windows

Let’s go ahead and change the Boot order of the device, first being the CDROM1 and the VirtIO disk and the CDROM2.

Note : The important part is for the KVM to load the windows 10 image from the list.

Check the option Enable boot menu.

Once you rearranged the boot loader click on Apply.

5. Configure the qemu CPU the right way.

Click on CPU and change the current allocations to 4
Check the options which say manually set CPU topology.

In the topology assign 1 socket, 2cores and 2threads.

6. Begin the windows 10 VM installation.

We just finished adding the required virtual hardware, you may now click on Begin installation.

If everything went well, you should be able to see the windows logo, and after few seconds Windows prompt where you have to choose the language and the time and date and the keyboard click on Next.

You will have to click on install now on the next prompt.

Just like you did the driver update for other devices, do the same thing for the display adapter as well.
