Nested virtualization not available in Solaris 11.2

Question

Hello!
Anybody know why virtual hardware virtualization is not available for my Solaris 11.2 guest?
I want to be able to use Solaris kernel zones.
Host environment:
   SuperMicro A1SRM-2758F, 32GB RAM
   ESXi-5.5 (build 2302651)
I know the CPU (Atom C2758) supports both VT-x and EPT that is required for 64bit virtualization nesting
And browsing to:
   https://myip/mob/?moid=ha-host&doPath=capability
Shows me that the (unsupported) feature is available:
   nestedHVSupported
boolean
true
I have created a VM with vHardware vmx-10, selected 'Expose hardware assisted virtualization to the guest OS' and installed Solaris-11.2 as a guest.
I have also checked that 'vhv.enable = "TRUE" ' is to be found in the vmx file.
But from the Solaris guest Kernel zone are not available:
# virtinfo
NAME            CLASS
vmware          current
non-global-zone supported
# uname -a
SunOS global1 5.11 11.2 i86pc i386 i86pc
Anybody have any ideas why this is not available. Worked fine in VMware Fusion.
Best regards,

Hello jmattson!
I tried to add:
  vvt.etmt.uc = "TRUE"
to the vmx file and according to the log it got picked up:
2015-03-31T20:03:40.790Z| vmx| I120: DICT
featMask.vm.hv.capable = Min:1
2015-03-31T20:03:40.790Z| vmx| I120: DICT           
vhv.enable = TRUE
2015-03-31T20:03:40.790Z| vmx| I120: DICT          
vvt.etmt.uc = TRUE
2015-03-31T20:03:40.790Z| vmx| I120: DICT sched.scsi0:4.throughputCap = off
2015-03-31T20:03:40.790Z| vmx| I120: DICT sched.scsi1:3.throughputCap = off
But Solaris will still not support kernel zones:
# virtinfo
NAME            CLASS
vmware          current
non-global-zone supported
Will I then need to upgrade to ESXi-6 - and downgrade to the Web Client :'( for this to work?
Best regards and thank you SO much for your help!
