+# Create the VM
+
+Start virt-manager
+
+```bash
+virt-manager
+```
+
+When creating VM:
+
+- Local ISO
+- Windows 11 ISO
+- Firmware: UEFI (OVMF)
+- Chipset: Q35
+- TPM: emulated
+
+Before you start the VM:
+
+```bash
+sudo vim /etc/default/ufw
+```
+
+Find `DEFAULT_FORWARD_POLICY="DROP"` and change it to `DEFAULT_FORWARD_POLICY="ACCEPT"`
+
+Now boot the VM.
