Tom, make more videos on XCP-NG. Building clusters, HCI, and so on

Watched this when it came out. Lost the (only) boot drive on my homelab's master last night. Thanks for the help!

thank you for such useful video, much appreciated 😊

Hey Tom. Thank you for teaching me about xen. Definitely going to try it out for a new hypervisor for my facility. I have a number of vms that need to connect to physical usb devices. I use SEH technologies usb to ethernet appliances. Do you have any experience on using such equipment on a xen hypervisor?

One thing I don't ever see touched on is how easy it is to leverage Cloud-Config scripts in XCP-NG to quickly deploy linux machines, or in my case, ubuntu docker swarms. We can then take these same scripts and reuse them in AWS.

Tom thanks again for useful tips with XCP-ng management... I would super appreciate some tips and thought maybe on how do you manage your XO update flow???

I know the recommendation is to be always on latest commit available within a 'master' branch, but sometimes it just seems it's a little "broken"? ...right now 236 open issues, some of them from last 2 weeks a bit serious.

Do you have an update strategy how you pick up safe commits to update to and not to fall into problems? (or just try and roll back XO vm in case of troubles)?

Thanks for an opinion and may be for an advice, have great day everyone.

Coming from the VMware world, this was definitely one of the most confusing things when starting to play around with XCP-ng, that the master does not get chosen automatically in a HA cluster.

That are some great tips, didn't know you can get the xcp-ng screen via ssh, i have a system without a videocard, now i don't need to add a videocard incase of an emergency.

How can I setup the symbols you are using behind the vm names?
