SecurityOnion installation from ISO on OpenNebula

I just tested the installation from iso.

TL;DR: you’d need to define a relatively new CPU Model for installation to work.

The installation is based on OracleLinux 9.2 which is RHEL9 derivate that requires CPU capabilities x86-64-v2. More details here

The supported microarchitecture levels could be seen using this command, but you’d need to install (other) Linux using the same VM definition.

root@u24onekvm2:~# /lib64/ld-linux-x86-64.so.2 --help
Usage: /lib64/ld-linux-x86-64.so.2 [OPTION]... EXECUTABLE-FILE [ARGS-FOR-PROGRAM...]
...
Subdirectories of glibc-hwcaps directories, in priority order:
  x86-64-v4 (supported, searched)
  x86-64-v3 (supported, searched)
  x86-64-v2 (supported, searched)

Hint: I’ve used the trusty old Ruby Sunstone interface because the new Fireedge interface lacks configuration options and also on VM update removes bits of configuration made via other means (Ruby Sunstone, CLI tools, etc)

I hope this helps.
