XenServer Questions

------------------------------------------------------
Hi folks,
Yep, this is me. I'm thinking about moving some (or all) of my stuff over =
to Protonmail, and thought I'd go ahead and subscribe to Chugalug on this =
email address.

I'm looking into possibly deploying some hardware soon, and just about fel=
l out of my seat when I saw how expensive VMware costs when you want High =
Availability.

Does anyone use, or have experience with, XenServer? How hard is it to set=
up with 2 different physical servers for a HA environment? How hard is it =
to manage & create new VMs? Have you been happy with it? Is it worth my ti=
me?

=============================================================== From: Lynn Dixon ------------------------------------------------------ If you are looking at buying vSphere, why not take a look at Red Hat RHV? https://access.redhat.com/products/red-hat-virtualization If you are looking to save money, you can check out the upstream opensource project that drives Red Hat RHV.....oVirt: https://www.ovirt.org/ You could do HA using two machines using RHV or oVirt, and creating VM's is actually quite easy with the slick WebUI or you can leverage Ansible to do provisioning. It also has an API that is easy to work with. To be quite honest, I have not seen XenServer being used in production for a LONG time. On Fri, Oct 19, 2018 at 7:13 PM David White wrote:

=============================================================== From: David White ------------------------------------------------------ Thanks, Lynn. I'm not looking at vSphere, now that I know how much HA costs. No freaking= way. Come to think of it, Linode did migrate off of Xen hosts a couple years ag= o onto KVMs, and I know other cloud providers tend to use KVM over Xen the= se days. So what you say makes sense - Xen is old technology. Will RHV run or require any sort of RHEL subscription? In other words, do = I need a Red Hat account to run RHV with oVirt? Or maybe I should just go = to oVirt as you say...

=============================================================== From: David White ------------------------------------------------------ Ah, yes, looks like oVirt would be a much better way to go.

=============================================================== From: Stephen Kraus ------------------------------------------------------ Xenserver is easy as pie. Its very robust, and HA can be done without difficulty. Building out VMs is just as easy. I use Xenserver at home and in our Offensive Security Lab (Cussing Allowed) Sandbox environment.

RHV is one of our products, and its sold with RHEL. But, with Red Hat, you are paying for support. If you want to save money and do self-support oVirt is the way to go. oVirt will be slightly ahead of RHV as far as features and updates. The community is pretty good around it, most of the folks on the oVirt mailing lists are going to be Red Hatters writing the code the goes into oVirt (and eventually RHV) and they are usually pretty quick with replies to the list. They also hang out a lot in #ovirt on Freenode. I personally use oVirt in my own lab that I have co-located with Peace, and I also use it for my home server (it hosts all the servers I have at the house...Plex, IdM, Satellite, and a few other home stuff). OH!!! AND DONT FORGET! You can sign up for a free Red Hat developer account and get access to all our products, and run them self-supported. https://developers.redhat.com/ This also gets you access to the documentation, updates from RHN, in addition to the products.

=============================================================== From: Billy ------------------------------------------------------ Just an FYI about the developer subscription: =E2=80=9CThe major difference between a full commercial Red Hat subscription= and the Developer Program subscription is that the Red Hat Developer Progra= m is intended for individual developer-use only.
