        Is the problem occurring both when the vm's are on HDD and on SSD storage or only on HDD ?

          @hoerup on both. I allready thought this could happen on some idle thing on the hdd's, but same problem on the ssd's, so that could not be the cause

            Can you try ext/thin instead of LVM? Not that this should matter that much.

              Looking at the video it seems the writes get queued up (Dirty in /proc/meminfo). I wonder why writes are so slow.

              What filesystems do you use on the guest?

                this was the standard from xcp-ng during installation. The problem is that there allready are VMs on this machine and i can't reformat it without any problems (no other hosts in this data center where i could use the same IPs).

                guest system uses ext3

                        now i noticed that tje jdb2 and kworker processes have gone... but system is still extremly slow

                        https://www.pzka.de/xen2.mp4

                        on this video i try to install munin for future data to analyse the problem. As you can see absolutly nothing happens (this can take many minutes now). There is a rsync "running" at a very slow speed, but as you can see cpu usage is ultra low and also top says no system load.

                        I think it must be a problem with xcp-ng, but I have no idea what it could be.

                          Can you do a dmesg and also a smartctl -a /dev/sdb and smartctl /dev/sda?

                            i haven't installed smarttools on the VMs, but i can do.... from the video to now the apt for installing munin is on 4% now. it tooks very very long

                                that is the first host (i have only 1 raid on the ssd and 1 single hdd on this host)

                                it takes about 3-4sec for smartctl to display the data there

                                  All disks are taking 3/4 sec to display smartctl ?

                                    only the 4TB hdd. i also have testet it on the other dom0, there it's quicker. Maybe it's related because there are some running rsyncs on a virtual machine to this disk.

                                      @olivierlambert definitely doesn't ring any bells but definitely smells like a storage issue, I would test disk performance directly in dom0 on the RAID SR using something like FIO, although we don't provide this in our repos so that would be difficult to get in dom0. perhaps a simple dd speed test under the SR mount directly, you should be able to find it by running df -h. Just be sure you don't overwrite any VM disk files 🙂

                                        i would agree that it sounds like an storage problem, but it's unlikley that this happends on 2 brand new machines at the same time and the dom0 should be affected with the same problems when it's a hardware case.

                                        What does this "vif vif-5-1 vif5.1: Guest Rx stalled" mean? Rx stand for some information recieve?

                                          @Andi79 it's impossible to say without more testing, it could be a firmware issue on these boards causing IO stalls or similar, the only way to be sure now is to run some perf tests inside dom0 to confirm it's not VM related, once you get that confirmation, install (or live boot) plain CentOS on one of the machine and test there as well. Are both the SSD and the HDD underneath an mdadm software raid? I suppose it could be a software raid configuration issue as well, but it's hard to say without further testing

                                            @Andi79 the guest RX messages are normal, some OSs like debian etc put unused interfaces in some type of "sleep" mode if I remember correctly and this causes these harmless messages
