On my home file server for example, which is not connected to the

work, and be supported with updates for 10 years and I can largely
forget about it. My el5 box ran for more than 10 years until the
hardware eventually died.
EL5... how modern... from a production application server VM, not
internet-connected:

This one has to be hard reset every day or two (virsh reset rhel2.1)
since the bridge to the guest just dies randomly, and a reboot inside
the guest hangs hard before finishing the reboot. The hard reset has to
manually load the ethernet kernel module after it's booted up so far; if
the ethernet module loads too soon it will never connect.... haven't
found the reason for that, either, just run a pinging script every
fifteen minutes on the host to check for connectivity and 'virsh reset
rhel2.1' when it fails. The appserver is hard reboot resilient, and the
software does a very specific task, and there's no budget for a
rewrite. At least I did upgrade it from Red Hat Linux 5.2 a couple of
years ago (the RHL5.2 box, an old AMD K6/2-450 with 128MB of RAM, ran
almost continuously for 20 years).
Thanks, CentOS!
