Subject Re: Modifying a service offering in the cloudstack DB
Date Fri, 21 Jul 2017 06:59:47 GMT
Hi Ivan,

thanks für die quick reply. 

Would you mind elaborating somewhat further on the potential implications. Can I avoid unfaire
resource provisioning by modifiying all existing service offerings equally, e.g. changing
the CPU Speed of all offering from 1999 to 1995 MHz?

Cheers,
Christian
