      Okay so it's not the right topic indeed, but I really want to know if you still have these issues on 7.6 RC 🙂

          Thanks a lot! It's important to test between 2x 7.6 hosts, to be sure it's still an issue and not a problem from another version in the middle 🙂

            Mine is between multiple 7.6 hosts. PV tools, no PV tools, linux, windows. It all does it.

                No snapshots. It happens on both storage migrate and love migrate.

                  Any activity in the VM or it's idle?

                  Are they in the same pool?

                    Same Pool. It does not seem to matter if it is idle or not.

                      Interesting update: I installed the latest PV tools by enabling window update, this fixed 4 out of my 5 test VMs running windows. More testing is underway with linux PV and HVM.

                        That's maybe the reason why I can't reproduce. It's like old tools will lead to migration problems but not more recent ones 😕

                          HVM also have migration problems.

                            I'm testing with PVHVM guests, I can't reproduce since I got latest tools installed 😞

                              I don't know if this helps but I have also been doing some test on 7.5 and it looks like VMs that are using a large percentage of their memory have problems migrating.
                              eg Centos 7 HVM with Atlassian bitbucket java process using about 80%
                              From top:

                              PID USER      PR  NI    VIRT    RES    SHR S  %CPU %MEM     TIME+ COMMAND 
 1874 atlbitb+  20   0 3695600   1.3g   6440 S   0.3 42.8   0:52.40 java                 
 1891 atlbitb+  20   0 4154320   1.1g   8124 S   1.3 36.5   6:40.68 java

                              Live migration stops at 99% and stays there till you cancel the migration and I have seen it go to 100% and the VM crash.
                              You then need to restart the toolstack on the receiving server or
                              /var/log/xcp-rrdd-plugins.log
                              fills up with these messages

                               xcp-rrdd-squeezed: [ warn|xen1-3|0 ||rrdd-plugins] Couldn't find cached dynamic-max value for domain 66, using 0

                              Shut down the 2 java processes and it migrates OK.

                              I have also seen the same problem with migration of virtual disks between iSCSI SRs

                                  @KFC-Netearth That's really interesting. Do you have the latest tools version installed in your VM?

                                  edit: I'll try to use 80%+ RAM on a test VM and see if it triggers the problem 🙂

                                    I have this version of the guest-tools on the VM
                                    #rpm -aq|grep xen

                                      Seems to be latest tools.

                                      Do you have anything during the failed migration in /var/log/xensource.log? Or /var/log/SMlog?

                                        iSCSI possible problem:

                                        I install XCP-NG 7.6-RC1 on 2 node testing pool and I get error when I try to attach iSCSI SR.

                                        "The SR could not ne connected because the drive gfs2 was not recognized.
                                        Check you settings and try again."

                                        ![0_1540743412810_XCP-NG_7.6-iSCSI error.jpg](Uploading 100%)

                                        I create THICK volume:

                                        With Citrix XEN 7.6 works fine on same QNAP.

                                        Any idea what I do wrong or I encountered an error in XCP-NG 7.6.
