* src/esx/esx_driver.c (esxDomainSetVcpus, escDomainGetMaxVpcus): Move guts... (esxDomainSetVcpusFlags, esxDomainGetVcpusFlags): ...to new functions. (esxDriver): Trivially support the new API. * src/openvz/openvz_driver.c (openvzDomainSetVcpus) (openvzDomainSetVcpusFlags, openvzDomainGetMaxVcpus) (openvzDomainGetVcpusFlags, openvzDriver): Likewise. * src/phyp/phyp_driver.c (phypDomainSetCPU) (phypDomainSetVcpusFlags, phypGetLparCPUMAX) (phypDomainGetVcpusFlags, phypDriver): Likewise. * src/qemu/qemu_driver.c (qemudDomainSetVcpus) (qemudDomainSetVcpusFlags, qemudDomainGetMaxVcpus) (qemudDomainGetVcpusFlags, qemuDriver): Likewise. * src/test/test_driver.c (testSetVcpus, testDomainSetVcpusFlags) (testDomainGetMaxVcpus, testDomainGetVcpusFlags, testDriver): Likewise. * src/vbox/vbox_tmpl.c (vboxDomainSetVcpus) (vboxDomainSetVcpusFlags, virDomainGetMaxVcpus) (virDomainGetVcpusFlags, virDriver): Likewise. * src/xen/xen_driver.c (xenUnifiedDomainSetVcpus) (xenUnifiedDomainSetVcpusFlags, xenUnifiedDomainGetMaxVcpus) (xenUnifiedDomainGetVcpusFlags, xenUnifiedDriver): Likewise. * src/xenapi/xenapi_driver.c (xenapiDomainSetVcpus) (xenapiDomainSetVcpusFlags, xenapiDomainGetMaxVcpus) (xenapiDomainGetVcpusFlags, xenapiDriver): Likewise. (xenapiError): New helper macro. ---
Long, but consistent - anywhere the old API exists, this implements the new API, makes the old one a wrapper around the new, and makes the new API fail for any flag combinations not yet implemented.

Why not use virCheckFlags here?

virCheckFlags? This pattern reoccurs through the rest of the patch. Matthias
