Finally have an update!

I have both machines up and already have Ganeti setup between both of
them. I'm not quite ready to go live with the system yet but I'm hoping
by the end of the week (if not sooner) we will. I need to finalize
testing on the guest image deployment scripts and then we can start
deploying new VMs.

I probably won't have much of the documentation ready by then but it is
a high priority for me. I can at least get the basics online. The
physical machines will reside on our backend network so you'll need to
get access via our jumphost.

As for the VMs you need to decide which ones you'd like to have redudant
storage via drbd and which you don't. Since osgeo3 has much less disk
space its something to consider since it'll limit how much you can
deploy on osgeo3. I'd recommend you make a decision on whether you the
VM to always be online in case we need to reboot the machine for
security updates, etc. We can perform live migrations but only on VMs
which have drbd backed storage. Otherwise they will just use simple lvm
storage.

I haven't actually tested plain lvm storage yet so hopefully we don't
run into any major issues. Ganeti just released 2.1.0 a few days ago so
we're running the latest stable version.

It might be a great idea if you had one or a couple of VMs you'd like to
have setup ASAP that way I can set them up and make usre everything is
working properly. Afterwards I can give you documentation on how to
deploy new VMs on your own then.

I didn't check to see how the RAID was setup on the machines but I'm
assuming they are ok. Would like me to double check to ensure its in
RAID6?

Can you provide perferred usernames for each user and an ssh public key
for each as well?

I'm trying my best to get this done as soon as possible. Hopefully
everything will be ready very soon.
