@dinhngtu Thanks for your help. I solved to install XS Tools uninstalling old XS version 9.0, running XenClean and installing version 9.4. Also Disk stats now are correct. Now I get these good performances: [image: 1747727185969-a6beabc3-793e-41d7-9f03-4689db372275-immagine.png] [image: 1747727202526-20d58e2a-e9f9-4d7b-ba44-844dca2008fa-immagine.png]

Hi, Because it's not implemented I'm not even sure if we have this info in the XCP-ng's API already (I mean VDI stats), probably worth checking.

Just wanted to say thank you for this thread. I am in the midst of evaluating ESXi alternatives and trying ProxMox as well as XCP-NG. I just installed XCP-NG this morning and have been trying to figure out if I should be doing hardware RAID vs ZFS raid. This thread provided the answer I needed. Hardware Raid on my Dell Power Edge Servers is easy and reliable. Thank you again!

Hello, On a new server where I migrated about 15 VMs, same problem suddenly! Thanks for the tip, the Restarting Toolstack worked! (XCP-NG 8.2 / XCP-ng Center 20.04.01)
