Hi guys,

one of our Windows machines is reporting incorrect CPU usage. As per environment section it's a Windows Server 2008 R2 virtual machine, deployed as a guest on Citrix XenServer 6.2. It used to be a physical desktop, but has been converted to Xen compatible virtual machine using XenServer Conversion Tools. It works in HVM mode (as any other Windows virtual machine on XenServer) and the latest version of Xen Tools has been installed there.

Any other Windows virtual machine we running on XenServer is reporting CPU usage correctly, so it makes me think that it may be connected to conversion process (physical to virtual).

Please find CPU usage graphs from Zabbix and the machine itself in the attachment sections. I've found similar issue (ZBX-6462, but as per it's description there's no virtualization layer under the hood there.

Any help appreciated.

Regards,
Jakub
