Memory Usage wouldn't be displayed in XOA

fluffy-bunny

Hi there!

We've the problem, that the memory usage wouldn't be displayed on CentOS-VMs in XOA but on Debian and SLES11 based VM's it'll be displayed:

CentOS-VM:

SLES11-VM:

Under the 'Advanced Options' we can see that the 'Xen tools' aren't installed on the CentOS-VMs:

CentOS-VM:

SLES11-VM:

As it's discribed here (Xen-Orchestra Blog) it seems that only Debians Default-Kernel PVHVM Support.

Is it possible to enabled this also on CentOS-VMs to see the Memory-Usage in XOA?

Have you installed tools in your VM?

It seems that we haven't installed the Xen-Tools in our CentOS-based VMs. It's like as you have discribed it here, right? --> https://xen-orchestra.com/blog/install-xenserver-tools-in-your-vm/

Is there a possibility to reinstall the Xen-Tools without an reboot of the VMs?

olivierlambert

Yes, no need to reboot. Insert the tool ISO, and run the script

@olivierlambert :

Okay sorry, I've re-checked it and it seems that the Xen-Guest-Tools are installed on our CentOS-based-VMs:

[18:00:21][root@admin:~]$yum list installed | grep xen*
kexec-tools.x86_64                     2.0.15-33.el7                  @base

Please reinstall them of restart the service associated.

Hi @olivierlambert !

Thanks for your help but we've noticed, that on all of ours CentOS-VMs we haven't start 'xe-linux-distribution.service'.
After doing an 'systemctl enable xe-linux-distribution.service' followed by an 'systemctl start xe-linux-distribution.service' it works fine in XOA.

Thanks a lot for your help.

So yes, it was the service not started properly, so we didn't get the info into XOA You are welcome, enjoy it!
