[ale] Stable, backward compatible APIs

[James Taylor]

My 2 cents...
I do primarily remote support for all the linux servers I support, even when they're in the next room, and I use NoMachine whenever possible.
The free two user version is perfect for admin purposes, and I like being able to use an encrypted ssh connection that actually performs well for X and java apps on slow links.
It has clients for linux, mac and that other OS.
I only need one port open to get to all of the servers in the network, even if there are legacy platforms, like Windows servers in the mix. Just use NoMachine or RDP from my gateway server.

Me, too.  One admin (me) and only a handful of users of VMs.

If I had other tools that solve the same problem and can be run remotely
that would suffice.  But my "users" (well, VM admins) might not
necessarily be running Linux on their desktops, so that's why a
web-based solution seems "best".

All of my users are remote.  I was hoping to provide a way they could
access the VM without a login on the VM host (or even on another host
locally).  I suppose I could set up a VM for them to run from, but that
just seems silly and I don't know if virt-manager would work from a VM ;)

Fair enough.  I'm a Fedora user, personally, but I suspect recent Fedora
also has recent virt-manager.

Yeah, this can happen if you just use any rpm that works.  Modern Fedora
is pretty good about being inclusive, especially with the rpmfusion
repositories.  I've also had decent luck backporting RPMs as necessary.
Then again I've been using RPM systems since Red Hat Linux 3.0.3 back in
199x, so I'm very comfy there.

Yeah, I try to same thing.  (I'm using Zarafa instead of Zimbra).

Yep.  I'm just still trying to find a replacement for vmware-server!
