[ovirt-devel] Change in ovirt-engine[master]: restapi: NUMA feature restful API support

[Liao, Chuan (Jason Liao, HPservers-Core-OE-PSC)]

Hi Juan, 

Thanks for your reply. I try to add them to interface, seems that we still meet some problem:

Call restful API: api/hosts/e225422a-aeab-453e-b7ac-56c9f5ce378c/numanodes

Error occur:
java.lang.NullPointerException
	org.ovirt.engine.api.restapi.resource.AbstractBackendResource.linkSubCollections(AbstractBackendResource.java:264)
	org.ovirt.engine.api.restapi.resource.AbstractBackendResource.addLinks(AbstractBackendResource.java:206)
	org.ovirt.engine.api.restapi.resource.AbstractBackendResource.addLinks(AbstractBackendResource.java:196)
	org.ovirt.engine.api.restapi.resource.BackendHostNumaNodesResource.list(BackendHostNumaNodesResource.java:43)
	sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)

I am not sure that we have this links add into interface, could you give us some suggestion to debug it ?

Best Regards,
Jason Liao
