COMPONENT NAME

Configurable VMware Config Spec for hotadd actions in virtual machines in VMware 6.7+ environments.

CLOUDSTACK VERSION

6.14 , I suppose 4.14 is meant here, but new features are not implemented on released versions, so this will be 4.15, probably.

CONFIGURATION

vSphere 6.7

OS / ENVIRONMENT

N/A

SUMMARY

Some virtual machines should not be configured with hotadd support. Before vSphere 6.7 it is possible to overwrite the config via instance details, which are then translated to vmware extraOptionConfig (i.e. vcpu.hotadd=false).

Since vSphere 6.7 this is no longer supported, as the hotadd feature is not an extraOption anymore, but a vmSpecConfig, and this get's set by CloudStack based on OS-type (s. VmwareResource.java)

General idea is, to use the instance details to control the settings, i.e. if vcpu.hotadd=false is set in instance details, then set hotadd feature for vCPU to false as well in vmConfigSpec.

STEPS TO REPRODUCE

Instance detail is added with key=>value: vcpu.hotadd=>false

EXPECTED RESULTS

Above details get's translated to VM Spec Config: vmConfigSpec.setCpuHotAddEnabled(False)

ACTUAL RESULTS

Setting hotadd feature is only based on guest os descriptor.
