FWIW, I'm using OpenBSD as:
- 2 x redundant routers (running OpenBGPd)
- 2 x authoritative-only nameservers (nsd, in base system)
- 2 x recursing resolvers (unbound, in ports)
- 1 x LDAP server [being built] (ldapd, in base system)
- 1 x mail server [being built] (smtpd, in base system)
- 1 x web server [being built] (nginx, in base system)
The routers are running on bare metal, to avoid a dependency loop if any
troubleshooting is required, but the rest are running as VMs, also
inside ProxmoxVE (HA cluster).
I'm running 64-bit images, with various things turned on (SNMPd,
wsmoused, etc.) so my memory footprint is more typically ~100-150Mb per
VM :-). They're still all running on the old VM host (1.6GHz old Xeon
CPU), so CPU usage sits around 4-5% steady-state. There are a couple of
documented tweaks to reduce that, but I've got cycles to spare so I
don't really care.
I do note that OpenBSD I/O isn't as good as Linux or FreeBSD to begin
with, and the virtio drivers have not yet been optimized much... their
existence brings OpenBSD I/O inside a VM up to where a non-virtio VM of
some other OS would perform, i.e. not fantastic, but adequate for pretty
much anything except a very busy database or file server.
(Just for a laugh: the routers each have 48Gb of RAM and 2 quad-core
Xeons. Ridiculously massive overkill, but it lets me use the identical
h/w platform for everything. At least BGP converges really, really fast
:-D!)
I know Edwin's aware, but others here might not be - I'll be
soft-launching a custom-hosting business shortly. I went looking for a
VPS host on Canadian soil that had IPv6 connectivity, and would let me
run OpenBSD... I came up completely empty, so I started building one.
And that's as much commercial advertisement as I'm willing to spring on
unsuspecting readers - contact me for more info.
