[libvirt] interactions between virDomainSetVcpusFlags and NUMA/pinning?

[Chris Friesen]

Hi,

Just wondering about interactions between virDomainSetVcpusFlags() and 
virDomainPinVcpuFlags() and the domain XML.

1) If I add a vCPU to a domain, do I need to pin it after or does it respect the 
vCPU-to-pCPU mapping specified in the domain XML?

2) Are vCPUs added/removed in strict numerical order such that at any given time 
the active vCPUs are numbered 0-(N-1) where N is the number of active vCPUs?

3) Will the newly-added vCPUs respect the NUMA topology specified in the domain XML?

Thanks,
Chris
