closed Can't Remove PIF #7193

Great to see this section on the forum. Thought I'd dive into what my Xen Orchestra looks like as a homelab enthusiast. I'll post more about the physical setup when I get things cleaned up.

All my servers are named after songs by my favorite Artist. Bare metal Servers get the names of Lead Singles. VMs get other names.

My Hosts:

• "Bodygold" - Ryzen 9 3900X - 64GB RAM
  This was originally designed to be my plex server, but after validating XCP-ng, I decided to let it join the pool.
• "Magnificent" - Ryzen 9 3900X - 32GB RAM (will be upgraded soon)
  Purchased build. After seeing it have a the same processor as Body Gold, I could finally do live migrations!
• "22Break" - Dell Optiplex 5040 - i7-6700 - 32GB RAM
  This is my old desktop. It will be decommissioned as soon as I upograde RAM of Body Gold and Magnificent.
• "LonelyStar" - Dell Optiplex 5040 SFF - i5-6500 - 16GB RAM
  Temporary, This only exists if I need to live migrate from 22Break.

My VMs

• Lifetimes - Docker Host.
  Uptime Kuma, Wyze to RTSP Bridge, SMTP to Telegram Bridge
• AllAboutYou - Windows 11
  I full-time Linux. I occasionally need a Windows 11 VM for a few workloads.
• HeartStrings - iVentoy
  Been messing with iVentoy for network booting my isos
• Nebraska - Jump Box - Apache Guacamole
• Landslide - Plex Server
• Little Tigers - NGINX Reverse Proxy
• Plans - Unifi Controller
• Heavy - SyncThing - Contains a clone of my desktop's Home Folder
• Dust - File Server
• WithoutYou - Wireguard VPN
• Church Website - I self-host my Church's website.
• DontYouWorry - Blue Iris
• HighOnHumans - Experimental FreePBX Server

Networks:

• Main Network - All personal devices
• Guest Network - Limited speed, also gives out DNS designed for adblock/family.
• Local - this is my "IoT network". No Outside Internet access. Although I do permit DNS and NTP.
• Experimental - This gets a DHCP address within the CGNAT range. If I need to configure a router or something, it'll go here.
• Experimental2 - Similar to Experimental, but there's no DHCP Server running. This is if I need a VLAN to experiment around with.

@planedrop This is an added control plane.

It could be used for a few reasons:

• something happens with your XO, you can still manage VMs and even deploy XOA.
• You have a small enough setup that doesn't need XO. Such as just one host.
• Easy for beginners. I love XCP-ng, but explaining that the control plane is a VM that isn't automatically installed is quite strange to hear for some people.

@olivierlambert said in Run a script inside guest OS from host:

There's no mechanism in the Windows world to do things like you can do in Linux?

You can enable an ssh server in Windows Desktop and Server. It works just like Linux.

XCP-ng pretty much works on a good chunk of hardware.

• Before I switched, I did a validation test with an old Optiplex with a 3rd gen i5.
• Some on here use mini PCs.
• I’d be cautious, and probably avoid, modern Intel CPUs that use hybrid P (performance) and E (Efficiency) cores. Xen doesn’t work great with them.
• You can also use pretty much all server hardware. person favorites are the R720, and R730, although they’re starting to show some age

@stormi

I'll be testing the r8125 drivers.

• Able to install r8125-module-9.012.03-1.xcpng8.2.x86_64
• Able to reboot host and have Dom0 networking.
• Speed negotiated to 1000Mb/s. I don't have any 2.5G switches so can't test that.
• VM (Fedora Server 36) able to get an IP on untagged network
  • VM able to ping Internet IP (1.1.1.1)
  • VM able to ping internet DNS (xcp-ng.org)
• Changed to other network (VLAN 10 - my "Guest" Network)
  • Able to get IP from DHCP
  • Able to ping internet IP (1.1.1.1)
  • Able to ping internet DNS (xcp-ng.org)
• Able to migrate VM to host

@stormi yes, this is after a reboot.

@stormi
Thank you! I think I got it working. Previously had version 9.009. Now:

Tested with Ubuntu 22.04.4 LTS (Kernel 5.15.0-88-generic). Things are working well. Using XO Community 5fe53. Haven't updated hosts yet to November patches.

• Management agent detects
• Networking
  • IP Address detects
  • Can disconnect network
  • Can create network device, IP Populates
• VM Tasks - From XO
  • Can Pause/Resume
  • Can Suspend/Resume
  • Can Reboot
  • Can Migrate
  • Can Snapshot

@XCP-ng-JustGreat
We ended up doing the Registry bypass. After that was done it worked great!

We also tried things on our ESXi cluster, but due to licensing, couldn't do the vTPM. Also made sure to mention to my IT Manager about Olivier's 20-minute response to my forum post. Very much appreciated - hopefully I can get us to switch over.

On the VM's general page, click the plus, then the plus again.
