I have a fresh installation of Oracle VirtualBox and a standalone Almalinux 10 server, running on HP micorserver Gen 11 hardware. (I have successfully installed and run VM on VirtualBox on Almalinux9 in the past.)
I went to test the Almalinux 10 installation by creating a test VM.
I named the VM and then I went to select the .iso image. The file finder allowed me to navigate to the relevant .iso image, however on selecting it the system hanged. I have read a range of workarounds and explanations, the most relevant being Wayland c.f. Xorg. Tried the XWayland installation as recommended - no luck, same behaviour.
The only was I could get get a VM installed was to
- Create new VM
- Name it
- Finish without selecting the .iso
- Start the newly created VM.
- This then took me to a screen where I could select an iso image to install and all processed as standard linux installation.
Also - before I could get this to work (i.e. run the VM to get to loading the .iso image) , I had to remove the kvm module, i.e. modprobe -r kvm-intel otherwise I received a “Virtual box cannot run in VMX root mode….” etc. I had had the same issue with my Almalinux 9 server, so this was not unexpected.
The work-around listed above appears to work, however, I would rather be able to use the more conventional approach using the standard installation GUI to select the .iso file to install.. for simplicity’s sake 
I have trawled around the web, but have yet to find a really well described explanation of this issue. I am surprised as I would have though a RHEL derivative distro and Oracle should be well supported and work together, or at lease have a well described set of instruction to get things working - so I am keen to understand whether there are any issues in my installation that I could look out for and remedy. Thank you.
