------------------------------------
Summary: 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.
