Check if stress-ng is available/installed before running.
And do we need to align the stress-ng parameters with XVS?

what is $Config in xvs? it seems that in xvs the command stress_ng_test is somehow an alias

In XVS, it is defined in Framework/VMMCommon.sh:3189:function stress_ng_test()

the framework is CentOS distro specific, right? Or why hard code to install stress-ng through yum?

OK, it seems clear for me.

XVS is for Centos now, but we'd better support both Centos and Ubuntu in LKVS.

The parameters may correct now, btw according to xvs I only enabled 2_cpus for nxhp cases. |

stress-ng should be executed in VM, not host, you can refer to other cases in LKVS/KVM for consistent code style.
BTW, for host, we have "process" from avocado.utils.

only this one? what about installing and nx_hugepage configuration reading?

stress-ng installing is also in VM, nx hugepage configuration is on host. Just follow the case in XVS.
