Re: [Engine-devel] cluster emulation mode feature

----- Original Message ----- maybe better to name host field as supported_emulated_machines - since it holds the list of supported as reported from vdsm. the following is a copy from the wiki " consider this pseudo-code: operational = false if cluster.emulationMode == NULL for configVal in Config.ClusterEmulationMode(3.3) if configVal in host.emulationModes cluster.emulationMode = configVal operational = true else if clusterEmulationMode in host.emulationMode operational = true if (!operational) set host non operationl, reason = UNSUPPORTED_EMULATION_MODE " first, i guess where you write '3.3' its actually should be 'cluster.compatibility' another thing, the configuration will probably have more than 1 option for emulated machine, for example 3.3 rhel could have {(for EL-)RHEL6.4.0,RHEL6.3.0,..,(for other-)pc-1.3,pc-1.2..} we need to make sure the list is used ordered so that the greatest value will be first, since if host supports many, the latest will be used. in cpu-flags there is a specific number to do this order, maybe same approach can be taken here, as i'm not sure the RHEL/pc values are consistent (on my f18 i also have 'pc-i440fx-1.4')
