Patch Set 20: Verified-1 Testing show that ioprocess child processes are using same cpu affinity as vdsm; probably they are not started via execCmd, so they do not get their cpu affinity reset. Vdsm was configured with "cpu_affinity = 1" # ps auxf vdsm 4608 1.7 1.6 4858236 62056 ? S<sl 21:04 0:16 /usr/bin/python /usr/share/vdsm/vdsm vdsm 5164 0.0 0.0 538256 1260 ?
