Xenserver cores per socket

[Jānis Andersons | Failiem . lv]

Is it possible and how to set cores per socket in CloudStack 4.8.0, 
XenServer 6.5, Shared storage.

For now only way I know is to stop VM in XenServer and set cores per 
socket, and start it up again - but it keeps changing back to CloudStack 
settings.
