    Hello, I deleted the entire XOA and downloaded fresh image, recreated configuration and blank SR. The issue is gone. I will test some VDI migrations this week. There are is some performance impact and timeouts when creating 100-200 VMs on single 10 TB SR. I use xo-cli vm.create script. See you later

    Hello @codemercenary In theory Xen is NUMA aware (See https://wiki.xenproject.org/wiki/Xen_on_NUMA_Machines) so you would leave memory interleaving option of the BIOS off so that Xen does what it thinks is necessary. But these kinds of settings are very very workload sensitive and in fact it's usually a good idea to just test what works best for you. Regards, Yann

    Hello, I migrated our smaller DMZ VM cluster from VMware to XCP-NG and XOA a few months and have been using the community edition of XOA. Everything has been going great with no complaints. Recently I got approval to get a paid service subscription to Xen Orchestra. I have the licenses and imported the new OVA using the XOA deploy site. It successfully imports the VM and I can log in and connect my Vates account. My issue comes from importing the backup config that I have from my community edition to the new XOA. Everytime I try to import it, it says there was an error message importing. It seems to connect to one of the pools but none of the other information comes over. Missing backup jobs I created, missing remotes for backup jobs, plug in configurations. At first I thought it was because it was on a different version of XOA. I noticed that it uses the stable channel by default and it showed XOA being 6.2 I think. The community edition XOA we are running is running the latest 6.4. I did change it to use the latest channel and it did upgrade to 6.4 but it still said there was an error importing the config file. Is it possible to import our config from our community edition into the XOA appliance? Apologies as this is my first time actually using this edition of the XOA server.

    Hello, I’m experiencing an issue on an XCP-ng cluster using XOSTOR. Environment: 3-node XCP-ng cluster XOSTOR distributed storage (2x2Tob nvme on each host) XOA for management Management network 1Gb/s Storage Network 10Gb/s MTU 1500 everywhere (no jumbo frames) So during VM migrations, creation, destroy XOA loses connection to my host pool, VMs keep running normally Hosts remain reachable (SSH / HTTPS / ping OK), Connection comes back after some time 30s to 1min. Observations: No significant CPU or RAM saturation No obvious disk latency issues (iostat looks normal) No errors reported on NICs xapi process remains active (no crash or freeze) The problem is intermittent and seems random. i've monitored nic with iftop and i see no bandwith bottleneck et and can see that XOSTOR is using 10gb network only. Has anyone experienced similar behavior with XOSTOR? And how to Fix it ? Thanks in advance for your help.
