Are you perhaps accidentally launching the wrong kernels?

yeah, i think i'm in the right path, coz after create 2 guest OS in 2 vcpu
(vm1 n vm2), i'm install LITMUS inside (vm1 n vm2),
in root vm1 n vm 2 : uname -a
Linux vm1 3.10.41 #2 SMP PREEMPT Sun May 17 23:52:27 WIB 2015 x86_64 x86_64
x86_64 GNU/Linux

it's right?
so in my 2 vcpu (in root vm1 n vm2) i have done install LITMUS

in root vm1 n vm2 (after done install LITMUS), i check /proc/litmus and ls :
root at vm1:/proc/litmus# ls
active_plugin  cpus  domains  plugins  stats

each vcpu (in root vm1 n vm2) after done install LITMUS, i instal liblitmus
n ft_tools,
so in my 2 vcpu (in root vm1 n vm2) : ls
Desktop    litmus-rtxen
ft_tools  liblitmus

it's right?


could u tell me where is my wrong step n why i cant choose the active
plugin?
veryn thanks for your help,

regards..
