Running kernel seems to be up-to-date.

Pending processor microcode upgrade!

Diagnostics:
  The currently running processor microcode revision is 0x44 which is not the expected microcode revision 0x16.

Restarting the system to load the new processor microcode will not be handled automatically, so you should consider rebooting. [Return]


No services need to be restarted.

No containers need to be restarted.

No user sessions are running outdated binaries.

It looks like a VM running on a host using old cpu microcode.

needrestart 3.4 would detect that it runs inside a VM (#139) and won't do the microcode check at all.

Closed since it should be already fixed in a more recent needrestart version.
