If you already tried to use the OVA appliance of Wazuh, you probably saw the Wazuh splash screen, and then left with a black screen.
Unlike the Dell OME appliance (https://xcp-ng.org/forum/post/78651), the fix is pretty simple: we just need to reconfigure the grub.
To do that:
- Boot with any live CD with rescue you want (I use Debian)
- Follow the installer, and mount the /dev/xvda1 partition, and execute the shell on /dev/xvda1
cat /etc/default/grub
, you should see this file:

- From here, you can
vi /etc/default/grub
replace /dev/sda
by /dev/xvda
. Then :wq
- To reconfigure the grub, just do a
grub2-mkconfig
, the grub will display all its config.
- When the grub is done vomiting all its configuration, umount the DVD on your VM, and reboot, and tada !

To install the tool, log in the console, sudo -i
, plug the guest-tools.iso, mount /dev/cdrom /mnt
, and bash /mnt/Linux/install.sh -d rhel -m 9
The tools are now installed ! 
If you have a question, don't hesitate to ping me !
