-------------------------------------
Resolution: Won't Fix
> Allow topology definition (socket/core) in the service offering (KVM)
> ---------------------------------------------------------------------
>
> Key: CLOUDSTACK-5071
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-5071
> Project: CloudStack
> Issue Type: Improvement
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: KVM
> Affects Versions: 4.2.0
> Reporter: Arnaud G
> Priority: Critical
>
> Today if you create a VM for KVM you can only export vcpu and not core, The
> complete topology should be provided in order to really support Windows VM on
> KVM.
> Windows VM for licensing issue can only see a limited number of socket (for
> instance 2 for Windows 7/8 or 4 for Windows server standard 2008/2012). This
> means that with the current implementation it is impossible to make the VM
> really benefit from the underlying hardware and limit the capability to use
> Windows VM on Cloudstack + KVM.
> Currently CPU are exported as:
> <vcpu>8</vcpu>
> and it should rather be done like this:
> <vcpu>1</vcpu> <cpu>
> <topology sockets='1' cores='8' threads='1'/>
> </cpu>
> The setup of this kind of configuration should be part of the service
> offering. (it will involve a GUI modification)
> This improvement request is linked to CLOUDSTACK-904. This JIRA should be
> close if this improvement is accepted.
