    Hello there, We have a production pool (2 hosts) that is in dire need of a new host, so we removed an newer host from another pool, but we stepped on something that i knew could be an issue. The production pool has 2 hosts on xpc-ng.8.2.1, that had issues updating to 8.3, each host has 8 PIF interfaces, 4 copper 1gbps, 4 fiber 10Gbps. 2 of the copper PIF are not used. The newer host only has 6 PIF, 2 copper 1gpps and 4 fiber 25 Gbps. I made sure the PIF order on the new host matches the order of active PIF. When i try to add the new host to the pool, the dom 0 on the new host stops having network access, and shows no PIF. Configure Management Interface reports <no interfaces present>. I bet the issues is the PIF mismatch, is there anyway i can disable the unused PIF and get add the new host? Can it be a software version missmatch? we didn't update the new host after install, because the pool is one patch behind. Bonus question, is there a way to install guest tools on older Operating systems, like windows XP and centos 4, for some old guest systems we need to keep arround ... (yeah i know we should get alternatives ...)

    I appreciate the comments and they are all welcome. Do keep note that I did say this is not Production ready and use at your own risk. If you see anything that is wrong please provide suggest feedback to correct said issue. I just started running my home lab from this version yesterday. I imported my config from previous XO. Today i saw 4 new commits and the update function updated to the latest commit. Backups have run with no issue. As I can only test in my home lab I can only speak of my own experiences.

    @tmnguyen You can open a support ticket and request that we reactivate your XOSTOR trial licenses to match your existing XOA trial.

    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.
