When creating a VM, check "Customize configuration before install". Make the following changes:

1. In the CPUs tab, select "Copy host CPU configuration" and click Apply.

2. In the XML version edit the =<clock>= section as follows:

#+begin_src xml

<clock offset='localtime'>

<timer name='rtc' present='no' tickpolicy='catchup'/>

<timer name='pit' present='no' tickpolicy='delay'/>

<timer name='hpet' present='no'/>

<timer name='kvmclock' present='no'/>

<timer name='hypervclock' present='yes'/>

</clock>

#+end_src

The source says it will disable all timers except for the hypervclocks, reducing idle CPU usage.

Also enable Hyper-V enlightenments in =<hyperv>=:

#+begin_src xml

<hyperv>

<relaxed state='on'/>

<vapic state='on'/>

<spinlocks state='on' retries='8191'/>

<vpindex state='on'/>

<synic state='on'/>

<stimer state='on'>

<direct state='on'/>

</stimer>

<reset state='on'/>

<frequencies state='on'/>

<reenlightenment state='on'/>

<tlbflush state='on'/>

<ipi state='on'/>

</hyperv>

#+end_src

Add this device under =<devices>=:

#+begin_src xml

<channel type='unix'>

<source mode='bind'/>

<target type='virtio' name='org.qemu.guest_agent.0'/>

<address type='virtio-serial' controller='0' bus='0' port='2'/>

</channel>

#+end_src

3. In the SATA Disk 1 section, section set the Disk bus type to VirtIO.

4. In NIC section, set the device model to virtio.

5. [[https://docs.redhat.com/en/documentation/red_hat_enterprise_linux/5/html/virtualization/sect-virtualization-security_for_virtualization-selinux_and_virtualization#sect-Virtualization-Security_for_virtualization-SELinux_and_virtualization][Download VirtIO drivers]]

6. Add a CD-ROM device with the VirtIO driver ISO.

During installation, load the VirtIO driver in =\amd64\w11=. The disk should appear.

After installation, open the VirtIO driver ISO and run =virtio-win-guest-tools.exe=. Then, the option at View > Scale Display / Auto resize VM with window should work.

Configure DNS to 1.1.1.1

To configure a shared folder:

1. Toggle "Enable shared memory" in the memory tab.

2. Click "Add hardware" -> Filesystem, select virtiofs as the driver and specify the paths.

3. Install [[https://github.com/winfsp/winfsp/releases/][WinFSP]] on the VM.

4. Run:

#+begin_src shell

sc.exe create VirtioFsSvc binpath= "C:\Program Files\Virtio-Win\VioFS\virtiofs.exe" start=auto depend="WinFsp.Launcher/VirtioFsDrv" DisplayName="Virtio Filesystem Service"

sc.exe start VirtioFsSvc

#+end_src

5. Reboot the VM.
