ethtool -s eth3 autoneg off
ethtool -s eth3 duplex full
ethtool -s eth3 speed 1000
hello I did the above commands stuck at the last command network access is gone. Still did not respond. How can I solve if I need to wait command. The problem may be the cause. "ethtool -s eth3 speed 1000" I waited a long time for my article and access was gone.
xcp-ng 8 and 8.2 network speed problem "Cannot advertise speed 1000"
I tried to provide the solution in the link below, but after the server restarted, you lost network access. I rolled back the operations in the same way again. can you help me

When I issue the shutdown command to the host / physical machine via xoa, the process does not occur. it gives an error.
Stop
no hosts availeble
xcp-ng 8.2 XOA operational process also has errors. I get an error after doing suspend on the interface.
XOA ubuntu 20 vm suspend it gives an error message in red on the upper right of the console.
XOA ubuntu 20 vm Start (Gives an error after the first press "Async.VM.resume: 10%"gets stuck )
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.
After ubuntu installation it gets stuck on "blocksclean" screen. I have an AMD processor on my computer. The processor does not have a graphics card feature. Also I am using an external RTX graphics card. What can be the problem.

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.

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.
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.

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.
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.

You attempted an operation on a VM that was not in an appropriate power state at the time; for example, you attempted to start a VM that was already running. The parameters returned are the VM's handle, and the expected and actual VM state at the time of the call.

The server failed to handle your request, due to an internal error. The given message may give details useful for debugging the problem.

@ruskofd I turned off the C1E and C States features. Problem is solved. But SSD performance is very low compared to windows machine.
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?
@tuxen said in xcp-ng CPU low performance issue:
Start a VM boot storm (or a stress test inside one or more VMs) in order to generate some CPU load.

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.
