One question, I promised to forward to the forum, how many VM are you running on XCP-ng ?
Dozen, hundreds, thousands or more ?
@afmart_dei I'd be surprised that you can't add this host to the pool because it has a different number of PIFs... more likely than not the version mismatch is what is getting you hung up here.
Is there anyway to update everything to the same level, once that is done then you should be able to add this host to the pool.
As for Windows XP, CentOS 4 (CentOS 4 was EoL'd in 2012.... only 14 years ago) so that's likely gonna be a hard no. XP was in 2014.. likely the same boat.
The issue likely being that no one wants to program on old ass OS's to support something that the original dev no longer supports.
Just added the option for --proxy to deploy xo proxy.

Deploying a Proxy VM
The script supports deploying a Xen Orchestra Proxy VM directly to your XenServer/XCP-ng pool using the --proxy option:
./install-xen-orchestra.sh --proxy
Important Limitations and Notes
️ Network Configuration:
The --proxy option does not allow you to specify which network the VIF is attached to
It will default to "Pool wide network associated with eth0"
️ Production Use Warning:
Use at your own risk. Not advised for use in production environments.
This feature is provided for testing and development purposes. For production deployments, it is recommended to manually configure proxy VMs with proper network planning and validation.

Difficile de parler de « réalité » avec les benchmarks. Vérifiez aussi l'iodepth (qui dépend du type matériel que vous avez, sur du flash/NVMe vous pouvez monter à 128 ou 256), la latence entre en compte aussi bien sûr.
Le bottleneck principal est le monothreading de tapdisk, si vous testez sur plusieurs VMs différentes la somme va monter de manière assez régulière.
