## Upgrade

- On RHEL/AlmaLinux 9, upgrading from OpenNebula 7.0 to 7.2 may fail due to conflicts between the distro nodejs 16 packages and the nodesource nodejs 20 required by `opennebula-fireedge`. The workaround is to remove the distro nodejs packages before upgrading:

```default
rpm -e --nodeps nodejs nodejs-docs nodejs-full-i18n nodejs-libs npm
yum upgrade opennebula
```

## Install Linux Graphical Desktop on KVM Virtual Machines

OpenNebula uses the `cirrus` graphical adapter for KVM Virtual Machines by default. It could happen that after installing a graphical desktop on a Linux VM, the Xorg window system does not load the appropriate video driver. You can force a VESA mode by configuring the kernel parameter `vga=VESA_MODE` in the GNU GRUB configuration file. [Here](https://en.wikipedia.org/wiki/VESA_BIOS_Extensions#Linux_video_mode_numbers/) you can find the VESA mode numbers. For example, adding `vga=791` as kernel parameter will select the 16-bit 1024×768 resolution mode.
