From: "Daniel P. Berrange" <berrange(a)redhat.com&gt; When adding variants of parameter setting APIs which accepted flags, the existing APIs were all adapted internally to pass VIR_DOMAIN_AFFECT_CURRENT to the new API. The QEMU impl qemuSetSchedularParameters was an exception, which instead used VIR_DOMAIN_AFFECT_LIVE. Change this to match other compatibility scenarios, so that calling virDomainSetSchedularParameters(dom, params, nparams); Has the same semantics as virDomainSetSchedularParametersFlags(dom, params, nparams, 0); And virDomainSetSchedularParametersFlags(dom, params, nparams, VIR_DOMAIN_AFFECT_CURRENT); Signed-off-by: Daniel P.
