@Andrew Good to know that version 8.2.1 includes the igc-module. I will need to figure out how i configured the PCI passthrough and recreate it successfully to attach it to my TrueNAS VM. Is there another way to include the igc-module in version 8.1.0? I managed to download the r8125-module, so why isn't the igc-module available?

@Andrew Does version 8.2.1 include the driver for Intel I225-V? Similarly, regarding PCI Passthrough, do you have any knowledge about doing upgrade with a configuration that includes PCI Passthrough? Do you have any advice or know of a guide?

Hi there,

I have XCP-ng running for a homelab setup, and I am upgrading my NICs because I am moving to a faster ISP with speeds over 1 GB/s. I bought Intel and Realtek network cards, both 2.5 GB/s, in case one of them would give some compatibility issues, features, or other reasons.

NICs:

TP-Link TX201 (Realtek RTL8125)
Intel I225-V

Running XCP-ng version 8.1.0, I followed the post "https://xcp-ng.org/forum/topic/7199/drivers-for-recent-homelab-nics-in-xcp-ng-8-2" and was able to download the "r8125-module" and the drivers are working fine. However, when downloading the "igc-module", I get an error saying the package cannot be found.

Because of this, I have two questions:

Is the igc-module package not available for version 8.1.0, similar to how the r8125-module is available for this version?
Ideally, I would like to upgrade to version 8.3 Beta 2 using the recommended ISO install. However, I want to know if I can perform the upgrade in place with the ISO with a certain level of confidence that it won't break my setup. On this XCP-NG machine, I also have PCI Passthrough configured for two hard disks to my TrueNAS VM (though I don't remember exactly how I configured it, I think I followed this guide: https://xcp-ng.org/forum/topic/1296/xcp-ng-recommended-way-for-host-dev-sd-ab-passthrough-to-vm-for-direct-control-access?_=1693380254932). Do you have any suggestions on this matter?

Hi Tony,

Excuse me for my late reaction but today i looked into this issue again with no success

VM [NOBAK] option and snapshot error in XO
I added the [NOBAK] quotes to the name of the disk i want to skip the transfer for and fired a manual snapshot job. Almost instantly i get the same error as mentioned before, screenshot and error details below.

Installing guest tools on FreeBSB (FreeNAS)
The xcp-ng documentation page describes that you will need to install 2 ports manually on FreeBSB. On following the instructions for let say sysutils/xe-guest-utilities on freshports[dot]org page it says to run the following commands:

To install the port: cd /usr/ports/sysutils/xen-guest-tools/ && make install clean
To add the package: pkg install xen-guest-tools

First command seems to fail on 'make' and second command i entered just to see what the output would be.

:SlapinFace: should have know that but didn't double check it.. anyways thanks!

Thank you @tony, based on your answer i now created delta backups with snapshot mode 'normal'. Tested the backup and restore with a couple of VMs Windows, Ubuntu and FreeBSB. With the windows and ubuntu VMs they where no issues. The FreeBSB with FreeNAS running throws an error: "UNIMPLEMENTED_IN_SM_BACKEND (OpaqueRef:9bfbc055-40c4-44a0-ab1a-9f3bac6dc718)".

Two things to note with the FreeBSB FreeNAS server:

There is second disk mounted, my data disk, to it. If possible can you exclude disks in a VM from a backup schedule?
There is no management tool installed on the VM. From my understanding freenas needs a different approach and before getting into that i want a backup.

After removing my physical nvidia graphics card and connecting the HMDI cable to my onboard adapter there is no video output. Looking in xcp-ng center -> host -> GPU i see "GPU configuration and monitoring is disabled, because there are no GPUs available on this host." and in XO shows blank/empty value.

Motherboard: ASrock Fatality B450 (link)
CPU: AMD Ryzen 7 2700X
xcp-ng: 8.1.0
xcp-ng center: 20.04.00

The isn't a very big issue because all of the management is done thru ssh, xcp-center or xo. But knowing i can't fallback on the possibility on managing the machine physically doesn't feel good. Is there a way in xcp to rescan its hardware, download or load the default onboard video drivers?

I recently migrated my homelab from VMware workstation to XCP-ng.
My homelab runs various servers on Windows and Linux like AD, Exchange, Nextcloud, FreeNAS and more.

On setting up a delta backup schedule i can choose in the settings -> advanced for snapshot mode and i wonder what is best practice for server like mentioned above.

Is it save to create delta backups of a exchange, database and others server with snapshot mode on 'normal' while in 'running' or 'halted' state or is it best practice to backup with snapshot mode 'with memory' or 'offline'.

So far i know shutting down the VM and then run a backup is the safest way. But i want to avoid that because of the dependencies of the servers on each other (LDAP, storage repositories and NFS shares linked to NAS, Reverse Proxy, etc)

Running:
XCP-ng: 8.1.0
XO-server: 5.66.0
XO-web: 5.69.0
All VMs have management agent installed
