      @olivierlambert said in XenServer 8.0 - Major update due Q1 2019:

      Please try with Xen Orchestra. You should be able to have this setting done once for all when the VM is halted, and then enjoy to set within the whole dynamic setting while it's up.

      I LOVE XOA! hehehehe
      That'S exactly what I wanted.
      Thanks so Much for the help and sorry for the persistence.

      But See the problem, VM Guest recognizes total memory.
      Is That a bug?

        I need to run some tests on XCP-ng, but IMHO you shouldn't be able to see the static max inside the VM. You should be able to see dynamic max.

          It's as expected in XCP-ng:

            I tested on other VMs and the memory displayed is always the maximum static.
            Will a Bug on XS 7.1?

              Possible, dynamic memory management changed a lot since 7.1

                If I remember correctly what I read, I think Windows guests see all the memory (static max or dynamic max, I don't remember) but there's a special device that "eats" the memory that is not available to the VM, so that what's really available to it corresponds to the dynamic value (between dynamic min and dynamic max).

                  It's dynamic max. But I'm pretty sure it was heavily changed in 7.2

                    @stormi It has always been the way that the daemon of xentools bloated up, when you need to free up dynamic memory within the range. I just have 7.1 LTSR running, can't verify for any CR, right now.

                      @olivierlambert I Did a test with the XS 7.6 and CentOS7 (HVM) and the memory calculation does not work correctly.

                      Sometimes it decreases the memory in the Guest VM, but never displays the values correctly. I am reinstalling the Host for XCP 7.6 and perform new tests. I'll open a new thread for that matter.

                        Behavior should be the same in XS and XCP-ng 7.6

                        If you have lower than dyn max in your VM, it's due to pressure of other VMs on the host. Also during a live migration, Xen will "deflate" the VM to dynamic min to allow faster migration.

                          Did anyone notice, that Citrix not only sucks with improvments for (non VDI) server admins, but also doesn't keep their promised releasedates? πŸ˜‰
                          Q1 is gone for some days and still no updates...
                          In fall our support contract ends, I'm following xcp-ngs roadmap and changes quite intense...

                            Well, in software development I prefer slipping release dates over broken software, so I won't throw the stone here πŸ™‚

                                      Yep, it seems they have some troubles internally to make it real. Hopefully, we'll have something soon. And yes, we agree that their (lack of) communication is disastrous.

                                        This is typical Citrix... XS isn't really a priority over there and havent been for many years.

                                            Exactly this. Not giving - especially paying customers - any feedback/info is just the worst way to do your business.
