I've freshly installed Red Hat 9, Rocky Linux 9, and Alma Linux 9 in VirtualBox 6.1.38. After each is freshly installed, they boot and run fine from a fresh installation.
Now, I then performed a "Export Appliance" of each of the Linux Appliances (i.e. Red Hat 9, Rocky Linux 9, and Alma Linux 9) creating an OVA for each of the 3. The exports all complete successfully.
However, if I try to import any of the OVA's, none of the distros will boot and I find myself stuck in "emergency mode".
No matter what I do, I can't seem to export a valid Red Hat 9, Rocky Linux 9, or Alma Linux 9 appliance and import it back in without each failing to boot under VirtualBox 6.1.38.[2.411066] Warning: Unmaintained hardware is detected: e1000:100E:8086 @ 0000:00:03.0
