????Usage??
????Netserver/(vmkload_app -i vmktcp)netserver-uw
????netperf/((vmkload_app -i vmktcp /netperf-uw -H host -t TCP_STREAM/UDP_RR -l 60 -***
????BTW?? ?????vmktcp?????
????“vmkload_app is a program launcher that loads vmkernel usermode applications onto the VMkernel. The APP is executed with the given APP-PARAMS and managed by the VMkernel. vmkload_app waits for the APP to terminate?? and will relay the standard input and output of the APP to and from its standard output?? and if a signal(7) is sent to vmkload_app it will be caught and forwarded to the APP. Only applications compiled for the vmkernel can be loaded. Additionally?? only binaries explicitly listed in the allowed binaries list?? /etc/vmware/UserWorldBinaries.txt will be allowed This is only useful on Classic. Because we are need to run the App in kernel level from COS. All app completed for vmkernel need to be ran in this way. Obviously?? on Visor?? no need to use vmkload_app….. "
