...Right. The fact that this has been lingering in the source for years on end and only now is being announced as a tech preview seems to answer my question in the sense that "no this is not possible" :S . Guess I'll have to fire up my build vm then and see if nuking that test for "kvm_nested" allows me to pass the svm cpu flag from a C6 host.

Hello, I'm trying to get the Android Emulator to run inside a kvm vm on CentOS-6. Apparently the latest Android Emulators cannot run without hardware acceleration so I am trying to get the vm to see the svm cpu flag. Host: $ grep model\ name /proc/cpuinfo | sort -u model name : AMD Phenom(tm) II X4 965 Processor $ grep svm /proc/cpuinfo | sort -u flags : fpu vme de pse tsc msr pae mce cx8
