action #113794
Updated by livdywan over 2 years ago
## Observation
With QEMU 7, the default video resolution was changed which caused #111992 since tests end up with an unexpected resolution. #111992#note-16 suggests using a prepared NVRAM image.
This might also be useful in preparation for #113357.
## Acceptance criteria
* **AC1:** Tests can boot with a custom NVRAM image
## Suggestions
* Maybe nvram tooling can be used to change the settings (efitools)
* The following can be used to manually generate a file. Create ovmf code+vars file, spawn VM, enter menu manually, then terminate the VM to save the file
```
/usr/bin/qemu-img create -f qcow2 -F raw -b /usr/share/qemu/ovmf-x86_64-ms-code.bin pflash-code-overlay0 1966080
/usr/bin/qemu-img create -f qcow2 -F raw -b /usr/share/qemu/ovmf-x86_64-ms-vars.bin pflash-vars-overlay0 131072

```
* See if we can generate the image in openQA or GitLab and automatically upload it as an asset to openQA's asset storage. Maybe small changes are necessary how we handle those special UEFI variables.
