1.nested virt ept]boot two L2 guests(Windows and RHEL) and execute some memory and IO stress test inside guest.
Setup:
1.Boot guest L1 need use "-cpu host"
2.install qemu-kvm inside L1 guest

Actions:

1. check default value
Intel:
#cat /sys/module/kvm_intel/parameters/nested
#cat /sys/module/kvm_intel/parameters/ept
AMD:
# cat /sys/module/kvm_amd/parameters/nested
# cat /sys/module/kvm_amd/parameters/npt
2. enable nested
2.1 Intel:
# modprobe -r kvm_intel
# modprobe kvm_intel nested=1
2.2 #cat /sys/module/kvm_intel/parameters/nested
2.3  AMD
# modprobe -r kvm_amd
# modprobe kvm_amd nested=1
2.4 # cat /sys/module/kvm_amd/parameters/nested
    # cat /sys/module/kvm_amd/parameters/npt
2.5  Boot L1 RHEL7.1 guest  with -cpu host
2.6. Boot RHEL7.1 guest and windows L2 guest on L1
2.7. do memory and IO stress test inside two guests
linux guest: use stress tools
windows guest: use iozone and MEM stress tools

Expected Results:
