What You Need to Know About XenServer

@Francesco-Provino Solution is creating a template with CloudInit process, then Xen Orchestra can do the rest. See https://xen-orchestra.com/blog/full-cloudinit-power-in-xenserver/

My new take on XS is to not touch XS. It's like Fight Club.
The easy way for ISOs I found was...
a) set up a new Linux Mint VM
b) set up an anonymous share
c) add ISOs
d) doneWindows works, but it;s hard to do anonymous shares, I've always found. You could create a user, which I did initially, but I've since moved to a small Mint instance and haven't looked back.

@olivier or via cloudinit, exactly, I just forgot to add it.

The thing is we already have CloudInit support, so it would be a shame to not using it

That's a way to do it also yes. In general, I've got always a physical machine (eg for backup) with enough space to do that. Doesn't require much bandwidth and power to simply share ISOs.

Thoughts @scottalanmiller ?

Yeah, just giving options.
There are many.
Anything that can share files would work. I just find sharing files anonymously through Windows maddening.

I have no idea, last time I tried it was 10 years ago.

It's probably why you moved on!

If I shared my SSD on my desktop how would I handle the permissions for mounting in XS? I did attempt this but it failed. Granted I had to leave immediately after and didnt get the chance to troubleshoot it.

You could create a local account on your machine, give it access to the shared directory, and use that when you mount from XS.
That's what I did initially.

I'll give this all a go when I get home and report back. Thanks everyone!

Extremely easy install. Everything up and running. Reading/Testing more tonight. How are you guys determining the need for virtual/physical cores per server etc?

I think the general consensus is to start with one core and add more if performance sucks.

Always! You should have a reason to be physical otherwise virtual.
-
@wirestyle22 Sorry, yeah.
Unless you're running a lot of heavily used VMs, a dual or quadcore CPU would be fine. My box at home runs a quad core cpu and has 5 or 6 VMs on it with no issues.

Just for my own knowledge, what would be a good reason to go physical? Just for a point of reference.

Again... General concensus around here is the only thing you need Physical for is to install the hypervisor. Everything should be virtual these days.

Maybe NAS/SAN storage, where massive I/Os and scalability is needed (note that you can connect a massive SAN/NAS to a pool so...).
Also, even real-time operations could be done with an Hypervisor now (Xen is going at full speed in automotive industry, via XenRT and Xen ARM projects).
