| 3 | Apart from the docker containers we see a need for virtual machines as well. In fact to be able to use TLJH we employ a Linux Container (LXC). This is because for technical reasons TLJH cannot be dockerised due to dependency on systemd. | ||

| 5 | For legacy application and alternate operating systems it is smart to be able to use virtual machines. It also makes deploying and roll-out very flexible. There are several techniques available to us that are good to use for different reasons. | ||

| 7 | As an example one would like to use ArcGIS for Windows. In that case you need to have a virtual machine windows guest available. ArcGIS would benefit from GPU passthrough so that option should be available ([[https:~~/~~/docs.oracle.com/en/virtualization/virtualbox/6.0/admin/pcipassthrough.html>>https://docs.oracle.com/en/virtualization/virtualbox/6.0/admin/pcipassthrough.html]]). | ||

| 9 | Choices to consider: | ||
| 10 | |||
| 11 | * VirtualBox (by Oracle) | ||
| 12 | * KVM/Qemu/Quickemu | ||
| 13 | * GnomeBoxes/VirtualManager | ||
| 14 | * Xen | ||
| 15 | |||
| 16 | KVM/Qemu based is preferred because of speed and robustness. A test with Quickemu was performed and show that it can be extremely easy to setup a virtualmachine with a Windows guest. However the Quickemu approach creates a NAT-ed userspace instance which is isolated and very difficult to access. It is possible to fix this but still needs some investigation. |
