    • Ram usage not showing on xcp-ng center.

      xen-tools is installed on vms of the linux ubuntu operating system, but I can't see the ram usage on the xcp-ng-center side. How can I overcome this problem.

      next then the vm icon turns blue
      It opens after 42 seconds after the next start. In addition, after the vm is opened, there are tears on the console screen.

      General distress also, there are no "PAUSE,SUSPEND FORCE REBOOT,FORCE SHUTDOWN,SNAPSHOT," options on vm management screen. These operations are only available in the main menu.

    • RE: Windows 10 (1803) - crash with installed guest tools

      as I mentioned in the previous answer. If there is a spare, you will return. If you don't have backup, all your data is garbage. The best solution is to install the Guest software directly from Xenserver.

      https://support.citrix.com/article/CTX235403

      Download and install 64bit from the link below. On the xcp-center side, you can monitor things like a memory disk, and you can solve the driver deletion problem that xcp-ng guest software could not do during the windows update.

    • RE: Windows 10 (1803) - crash with installed guest tools

      8.2.2.200-RC1 (and 8.2.2-beta) After installing the driver in this version (Windows 10 1809), access to the system was not possible.

      I've tried several recovery by installing Windows 10 iso. Start repair, Return, etc. but the result is the same.

      Blue screen at boot error: INACCESSIBLE BOOT DEVICE

      If you have a backup, go back or trash the virtual computer.

      I applied the video below but the result is frustrating. The file "\ windows \ system32 \ config \ RegBack" appears to be empty.

      https://www.youtube.com/watch?v=KAHAquUaR24

      Xcp-ng Center from the menu above VM > Start/Shut down > Start in Recovery Mode I start by following the steps, but the following warning comes.

      No bootable device
      Powering off in 30 seconds.
      How do we turn on safe mode on xcp-center in windows 10. I tried, but I can't open it.

      During VM export, the ssh connection is gone and the result is frustrating. the disk of the virtual computer does not appear at all.
      Xcp-ng 8.0 use. I think he sent the disk to eternity.

    • xe vm-start problem.

      I started exporting before the virtual server shuts down, and then I canceled the process, such as the goal of how to solve the problem there. Is there a solution in this regard.

    • Xcp-ng 7.6 to Xcp-ng 8.0 problem after migration

      Hi,
      I cannot upgrade the vCPU after I migrate virtual machines with Ubuntu18 operating system to xcp-ng8.0 new machine. It seems stuck at the highest value I have defined on the previous server. This may have caused the problem. The old server has a maximum value of 16 vcpu. The new server has a value of 64 vcpu, but I cannot raise it. How do I edit the bios or processor model of the virtual machine on xcp-center?

    • xcp-ng CPU low performance issue

      Hi,
      Dell r740 server SILVER 4210 processor headlight, but after installing xcp-ng operating system hypervisor operating system and virtualized windows and linux environments can not reach the CPU max value. I have checked all the performance settings in the BIOS, but unfortunately there is no solution. Note: it can reach maximum CPU value when it is checked by installing windows operating system directly on the current server.

      Intel Xeon Silver 4216
      22M Cache, 2,10 GHz
      xcp-ng 8.0.0

      I tested all the next version.
