+* Test the PXE install process on both `aimstest` and `aims`
+  * Upload the image to AIMS with `aims2client`, accessible on `aiadm`. i.e. `aims2client addimg ...` and `aims2client --testserver addimg ...`
+  * On the `"IT Linux Support - Test VMs"` create a VM with `landb-os=LINUX` as metadata and https://gitlab.cern.ch/linuxsupport/aims2-ipxe as image. You will already find uploaded images though so reuse one of them.
+  * Prepare the host to test the image as in the following example:
+    * `aims2client addhost yourtestvm --pxe --name CC79_X86_64 --kopts "ip=dhcp repo=http://linuxsoft.cern.ch/tmp/79/"`. Adjust the repo to the path from previous steps
+    * Open a VNC console on the web browser by going to the "Console" tab on the given test VM
+    * Go through the manual installation configuration. You will need to select "Reclaim space" on the partitioning configuration.
+    * If at any point you need to re-run the installation, rebuild the same VM with the same `iPXE-YYYYMMDD-aimsprod` image as before, then reboot and start again, it only takes a minute.
 * Update aims2-loaders to reference the new $release (see [https://gitlab.cern.ch/linuxsupport/aims2-loaders/commit/30de29e5cbd24b12379aaab098ed81d16340dded](https://gitlab.cern.ch/linuxsupport/aims2-loaders/commit/30de29e5cbd24b12379aaab098ed81d16340dded) for an example) and install on both aims and aimstest hosts
