CentOS

I'd go straight to 9 unless there is a reason not to. And I'd bypass Stream entirely and go Rocky/Alma.

It'll only sync with the host if you've told it to. Has the machine been "power cycled" since the VMWare setting was set?

CentOS Stream 8 is not EOL until 2024.

Since CentOS 7 is built from the sources for RHEL 7, any security bug that you might find should also be present in RHEL 7 so the best place you can report problems is using the Red Hat security@redhat.com email address or by raising a private bugzilla.redhat.com entry.

That's been built and pushed to the public repos so it should be hitting a mirror near you soon.

Thanks for spotting it.

Repositories will get moved to vault.centos.org. They would not be needed to install VBox anyway. But you are still going to be left with a system that will get no more fixes which may be fine... right up until it isn't and there's a major security vulnerability that will never get fixed. Be sensibl...

You are correct, it seems to have been missed. I have pinged the maintainer to get it build and pushed. The RHEL changelog says it was from Jan 2022 so this has been missing a while...

None of those are CentOS packages so you would have to ask whoever built them. The "cgslv6_2.561.g00e30d0ba" in the names are some weird non-CentOS dist tag.

You want ifup not ifconfig.

I need to add static route for only 2nd nic to reach a.b.c.d network so I have to create route-eth1 file ?

Yes. You may also need a rule-eth1 file too. And make sure your new ifcfg file does not contain GATEWAY= or it will become the default route.
