@gecant Yes. That hotfix was released with the XCP-ng March 2023 Security Update

@Denson You're welcome; glad to help.

@Denson You can mount from the CD in Xen Orchestra on the Console tab or install from the EPEL repo. (I always install from EPEL)

EPEL install:
dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm -y

Tool install:
dnf install xe-guest-utilities-latest -y
Be sure to enable and start after installing: systemctl enable --now xe-linux-distribution

@sb2014 In the 5.85 release of XO there were updates to the Netbox plugin that now requires three objects in the UUID field.

Here are the ones you need:

Virtualization > cluster
Virtualization > virtual machine 
Virtualization > interface

I recall a forum thread about this error. It should be fixed: (if using the latest XOA build or commit from source)
https://xcp-ng.org/forum/topic/4810/netbox-plugin-error-ipaddr-the-address-has-neither-ipv6-nor-ipv4-format

If on the latest, then there may be an issue with an IP in the pool.

@MrNaz I recommend reading the XO blog; updates are published monthly.

NBD was introduced in the 5.76 release and the ability to enable in the Xen Orchestra UI was introduced in 5.79

Also enhancements were released in 5.81

@fred974 I suggest installing on its own VM. I have never used Portainer to manage Kubernetes (only Docker containers) however, I usually use Rancher to manage K8s and I always install on its own VM.

@Phase1
A community built version is the most recent build of XCP-ng Center [v20.11.00.3], which may work with XCP-ng 8.3 Alpha.
It can be obtained from the following:

It is not an official client and unsupported by Vates.
