    @benapetr said in New project - XenAdminQt - a cross-platform GNU/Linux, macOS, Windows native thick client: @Pilow I know them a little bit, I will have a look, but I am now working on another new cool thing! It's called xen_exporter: https://github.com/benapetr/xen_exporter It's a prometheus exporter that hooks directly to xen kernel via xenctrl library from dom0 and extract all low-level metrics from the host, allowing very detailed graphs with very low granularity with stuff I always missed in both XenOrchestra and XenAdmin: ... We have a similar project : https://github.com/xcp-ng/xcp-metrics, but unfortunately it's not used as of today (though it could get revived as Rust for Xen matures, i.e easier to build). There is also Xen Orchestra OpenMetrics support but it's not on XCP-ng itself.

    @semarie This pool is still on 8.2.1, we are trying to add this host in order upgrade with little to no downtime.

    @rama said: @olivierlambert thank you. but is it possible to keep tracking all the CURD operation like we have in terraform. but currently MCP have only Read tasks. Like if some new interns in my lab don't know about this and in this agentic framework if he/she need a VM's, delete or update it can be done very quick. it will save many hours. I hope this will be available in future or if you wish to do tell me how far it is. The plugin MCP Server is read only by design to keep using it safe, to have an MCP for reading and another for writing is best practice. If you desire to have a separate MCP server for the writing actions, feel free to suggest that in the feedback portal. You can even develop your own MCP server, which makes calls to the write side of the XO REST API. https://modelcontextprotocol.io/

    Just wondering about a possible XOstor configuration as far as performance: 3 hosts, each can have 3 spinning disks for HCI. Need about 6tb of usable free space and understanding each host is essentially a mirror of the other hosts. Total 12 drives in the pool. What size drives would be best to achieve this? Would 2tb x3 drives give me this because they are not put into a raid like array on each host? Would I need to go 4tb x3 drives because it would make a RAID3 like array on each host? Or would I need larger x3 drives in each host? I only have SATA on these hosts. Also how close are we to a "from sources" guide this would certainly get prototyped in my lab with a different drive configuration (single nvme), but I'd need to plan ahead for production. Time always being against me, it would take months to get this prototyped and the demo period will run out multiple times while I'm trying to work on this. An example of time against me, I've had Harvester up for a month and still haven't build the first VM and haven't tried to get Rancher installed on a docker and integrated. It's certainly a much heavier lift to get to where XCP-ng and XO get you. I just feel like eggs in one basket is not something I should be doing (looking at you Broadcom and IBM ).

    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.
