@florent Where I do have an issue now is with Mirror incremental backup [image: 1747729830819-screenshot-2025-05-20-at-09.29.39.png] All VM's have this issue and fail mirror. Worked fine before the XO update yesterday: [image: 1747729967532-screenshot-2025-05-20-at-09.32.09.png]

@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]

@McHenry You can clone the VM, and remove the network of the clone before starting it

@Forza I don't know, I guess that's part of what I am trying to find out. How to get the metrics of the physical cpu usage. I thought that's what I would get with activating Netdata (Advanced Telemetry) from XenOrchestra.

@creoleMalady On your NFS server, do you have sync writes enabled or disabled?

@Forza said in Epyc VM to VM networking slow: olivierlambert said in Epyc VM to VM networking slow: If we become partners officially, we'll be able to have more advanced accesses with their teams. I still have hope, it's just that the pace isn't on me. Hi, is there anything new to report on this? We have very powerful machines, but unfortunately limited by this stubborn issue. Can you test https://xcp-ng.org/forum/topic/10862/early-testable-pvh-support ? We observe very significant improvements on AMD EPYC with PVH. We're still pin-pointing the issue with HVM, the current hypothesis is a issue regarding memory typing (grant-table accessed as uncacheable(UC) which is very slow) related to grant-table positionning in HVM.

said in XCP-ng Center 25.04 Released: Hello, I noticed that in this new version there is no option to connect to the server via Active Directory. I still use version 20.04.01 and this feature would be very useful. I would appreciate it if you could return this option. @michael.manley

@dthenot sure, here you go! [image: 1747679766913-0b424abf-68ef-4fb3-a8d3-b81001f0f314-image.png]

Can I get a link to the download?

@yllar Maybe it was because of the loopdevice not being completely created indeed. No error for this GC run. Everything should be ok then

@olivierlambert yes, I started to work on friday, and hopefully will have a fix today

Not a problem, something to be done correctly, and not implemented at all in the current XCP-ng API. In other words, it's not trivial You can create an issue in XO repo with all the details (and the screenshot), this at least needs some serious work to find what would be the best approach (and then sorted from our backlog)

Hi, Can you explain what you are trying to achieve exactly? And if you have an issue, what is it? edit: also please edit your post to use Markdown syntax for code block

Reping @dthenot
