Understanding How The XCP-NG & Xen Orchestra Open Source Virtualization Platform Works

As a soon to be VMware/Broadcom refugee, this information is extremely relevant and interesting! Thanks for a great summary of the key benefits and features!

Just spun up my first XCP-ng cluster this week because of your videos, keep them coming!

It’s always a good day when Tom drops XCP-NG content!

I've watched every video you have done on XCP-NG - each one better than the last. This latest video makes it so easy to make decisions and see how "other solutions" work compared to what we currently using. I really enjoyed this video and learned a LOT! Thank you again for taking the time to do this video!

As always, thank you for your extensive break-downs. I've been using XCP-NG for a few years now, and couldn't be happier. I replaced my VMWare cluster with it, and am not looking back.

Thank you for this. I've been thinking on switching from Hyper-V to XCP-NG for a while, mostly due to the backup options and this video made it a lot more clear.

I am excited Tom ❤ thank you for making a new series. I watch your old ones a ton still just modifying them with what I know of UI changes and feature changes by watching Oliver's videos/ forums to supplement.

Been following your videos in general, and helped me a lot, even did a PoC with XCP-NG @ work. Can't wait for the following videos.

Great overview! If I hadn't had made my choice to go with XCP-ng based on your previous videos, I surely would have made the same choice after watching this one.

Nice video, I'm pretty sure it will be linked in our next newsletter 😇

Great, clear helpful video. Next challenge is making the time to get setup with XCP-NG at home.

Two thumbs up for the series.

Can’t wait for more of this series

Good video Tom! Thanks for sharing it with us!💖👍😎JP

Thx for clear architecture overview. You certainly made me interested, seems like XO was wrongly in my blind spot.

@13:34 This is an important point. Although you can run XO on a VM on your XCP-NG pool it is a very good idea to have a XO running somewhere outside the pool. If for some reason the pool will not come back up (often some kind of issue after a HA failover) your pool VMs will not be running and so it is essential to be able to bring up XO somewhere else to be able to quickly examine why the pool won't come up - diagnosing the same with just the xen command line can be a lot more involved.

Xen was my preferred solution as early as 2004, Citrix for a few years in between, and now XCP-ng is my preferred solution since 2020. I'm currently building a business on it. Sadly the entry point of pricing is too steep to begin supporting the project. As soon as I make more money using it I will certainly support Vates. I never found running XO as a VM in the pool itself a good solution. I always run XO on a physically separate machine which I can control separate from the pool and its hosts.

This is such a great breakdown of how xcp-ng works. I wish there was something this thorough when I started learning about it, great job! On a different note, Something I think is worth mentioning anytime AWS and KVM is why AWS moved away from Xen. AWS KVM is not the same as the KVM one would spin up on any Linux box as it's highly customized and used for their specific design setup but the real important thing is the why. The reason AWS moved/moving from Xen to KVM is due to KVM being the specific piece (vmm iirc) they needed without having to work to extract that part from Xen as the other parts have been specially offloaded into hardware. There was nothing wrong with Xen itself. They needed a vmm and only a vmm, nothing extra and KVM fit the bill being a vmm only. This is information from a AWS Online Tech Talks about the Nitro Project.

I can't wait for XO 8 it's gonna be awesome!

You forgot to mention how mature the support for windows vm’s is. That’s a major reason why it’s ahead of the other contenders!!
