@olivierlambert Hello Olivier same thread is already open at Veeam

Hi everyone,

I’m currently testing Veeam Backup & Replication 13.3.2 Beta 2, which includes the new plugin for XCP-ng. I’m running the beta on a physical Windows Server.

Here’s the situation:
1. I had an existing Veeam installation on this server.
2. I uninstalled it completely, then installed the 13.3.2 Beta 2 version.
3. The installation went fine, the license was accepted, everything looked normal.
4. However, when I tried to add XCP-ng as a virtualization source, it was not available in the list.
5. I tried troubleshooting but couldn’t find anything obvious.

To rule out any leftovers from the previous installation, I:
6. Reformatted the entire physical server.
7. Performed a clean installation of Windows Server (fresh OS).
8. Installed Veeam 13.3.2 Beta 2 again — clean environment.
9. At this point, before restoring anything, the option to add XCP-ng as a virtualization source was visible.

But then:
10. I restored my Veeam configuration backup.
11. The restore went smoothly.
12. After the restore, XCP-ng disappeared again from the list of available virtualization sources when trying to add a new one.

So now I’m stuck:
• Fresh install = XCP-ng option appears.
• After restoring configuration = option disappears.
• I’m out of ideas.

Has anyone seen this behavior, or is there anything I might be missing? Any help would be greatly appreciated.

Thanks!

@DustinB please this thread : https://xcp-ng.org/forum/topic/10036/zabbix-on-xcp-ng

@DustinB

yum update && yum install -y pcre2 --enablerepo=epel,base,updates
rpm -Uvh https://repo.zabbix.com/zabbix/7.0/rhel/7/x86_64/zabbix-release-7.0-1.el7.noarch.rpm
yum update && yum install -y zabbix-agent2 zabbix-agent2-plugin-*

Connection is now ok i need to allow iptable to grant the connection.

I need to go deeper.

With Nedata can you monitor the host and receive all the informations on the vm hosted on it ?

because with Zabbix I think this is not possible to get this data.

Any idea ?

Re: Zabbix on xcp-ng

Hello,

i just followed the instruction to install the Zabbix agent on XCPNG 8.3.

Install is ok but this is impossible for me to receive the data to Zabbix.

No connection between the host and the zabbix server.

Is there anything special to specify when you add the host to Zabbix ?

Thanks

Hi everyone,

I’m facing an issue in my XCP-ng environment and would really appreciate some advice or best practices.

I have a pool with 3 XCP-ng hosts, and I’m running Xen Orchestra (XOA) as a VM on the second host (not the master). Everything runs fine under normal conditions.

However, if I reboot the master host, I temporarily lose all control of the pool through XOA. Even though XOA is still up and running on the second host, it can’t see any hosts, VMs, or storage — it’s like the entire pool becomes unmanageable until the master comes back online.

My setup:
• 3-host XCP-ng pool
• XOA is a VM on host 2 (not the master)
• When the master is rebooted, XOA loses access to the infrastructure
• When the master is back online, everything works again

My questions:
1. Is this behavior expected in a multi-host pool?
2. Is there a safe way to promote another host to master automatically or manually during planned or unplanned downtime?
3. Would it be better to run XOA outside of the pool, on a dedicated device (e.g., a NUC, VM on another hypervisor)?
4. Are there best practices for ensuring high availability of the management layer (XAPI + XOA)?

Thanks a lot for your help!

@Andrew How to find the good version in 8.3 ?

Hello everyone,

I have a client who recently ordered a new physical server infrastructure along with a SAN. They are currently running two CentOS hosts that haven’t been updated in five years. Given their strong preference for open-source solutions (they are a higher education institution), I’m considering migrating them to XCP-ng.

My initial plan is to deploy the fully open-source version of XCP-ng (Community Edition) to allow them to test the platform for about a year before potentially moving to the paid version at the end of 2025.

My main questions are:
1. Is the Community Edition stable enough for production use in this type of environment?
2. Has anyone here deployed the free version in a similar scenario, and what were your experiences?
3. Are there any key limitations in the Community Edition that might impact long-term adoption before transitioning to a paid plan?

The primary goal is to ensure a smooth migration and provide them with a reliable solution while staying within their open-source philosophy. Any insights or recommendations would be greatly appreciated!

Thanks in advance!
