+![Add VM icon](image-1.png)
+
+Things to set/look out for:
+
+- "Manual Install": as OpenCore loader can only deal SATA disks, you'll have to
+  add the install media yourself after the creation process
+- "Generic or unknown OS"
+- Memory: leave about 2GB to the host
+- CPUs: match or fewer than host's count
+- Disk image size: create one during the process or manually after creation
+- Tick "Customize configuration before install", Finish
+  - Click on "Apply" before leaving the view
+  - Chipset: Q35
+  - Firmware: UEFI
+  - Delete the NIC, audio, tablet, usb redirection
+  - Change the IDE disk to SATA
+  - Manually edit the xml
+    - Change the EFI images to the non secboot variant
+    - Turn smm off
+
+```xml
+<loader readonly="yes" secure="no" type="pflash">/usr/share/edk2/ovmf/OVMF_CODE.fd</loader>
+<nvram template="/usr/share/OVMF/OVMF_VARS.fd"></nvram>
+...
+<smm state="off"/>
+```
+
+Start editing the XML manually. Here's the breakdown of the changes.
+
+Add the xmlns spec. Without this, `<qemu:commandline>` tag won't persist.
+Without the tag, the xmlns spec won't persist either, so add the command line
+passthrough first.
+
+The qemu commandline passthrough is unavoidable because it is not possible to
+set up Apple SMC and custom CPU flags in Libvirt. It is also to circumvent the
+issue of libvirt's mandatory use of pcie-root-ports for the Q35 machine type.
+See [cloud+libvirt.md#caveats](cloud+libvirt.md#caveats) for detail.
+
+The PCI addresses are crafted so that they won't conflict with libvirt's
+allocation.

+
+Turn off memballoon.
+
+```xml
+<memballoon model="none"/>
+```
+
+That's pretty much it!
