XenServer VM startup is getting error: An unknown error occurred while attempting to config interface

[Barznj Abdullah]

Dears,

 

I have restarted XenServer and after that my VMs are not getting started again and I am getting below error:

((

An unknown error occurred while attempting to config interface

))

any suggestions on what will be the issue?

in Emergency Interface Reset, I will be able to give the IP to the current host where those VMs are running on. but I am not able to start the VMs due to no interface is configured.

 

waiting your kind feedbacks

For the console you can either use XenCenter to access the VM Console or you could access it with 

remote desktop if you have that enabled on the VM.

Sounds like your interface for your virtual nic isn't detected the same now for whatever reason. 

If all of your physical nics are being detected you may have to do a nic reorder to get the physical

nic you are using for your VM's to align with how the nic order use to be.  If the physical nic order

gets rearranged, then this sort of thing can happen.  But you can override the detected order.

Run "xe vif-list" to see what virtual network assignments exist. You may need to destroy and re-create the VIF for that VM.

dears,

 

Somehow I managed to make the interface to be OK, by some xapi service stop, restore db file and then start it again.

But now when I startup one VM which Windows installed on it, I can see it is not getting IP and its memory consumption is 100% used.

is there any way to check console for that VM and see what is its status? issue is that I dont have XenDesktop since it is asking for .NET 3.5. any other ways to access console for that VM?

 

really appreciate it

You can run the utility "xentop" from the CLI on your pool master to see the memory an CPU usage of each running VM.

Can you not access the VM's console via XenCenter?

There's also the VNC option if the VM can be configured to run that.

thanks alot dears, with xencenter, I managed to access the VM and made the interface up again. appreciate your supports as usual
