Hello to everyone.

while I was looking for a way to enable the nesting virtualization on my Jetson nano,after having enabled KVM applying these patches :

https://github.com/OE4T/linux-tegra-4.9/blob/oe4t-patches-l4t-r37.4/

When I have googled for acquiring more informations,I found these interesting threads :

https://patches.linaro.org/project/qemu-devel/patch/b7c2626e6c720ccc43e57197dff3dac72d613640.1616052890.git.haibo.xu@linaro.org/

https://superuser.com/questions/1838383/arm-cpu-nested-virtualization-how-can-i-make-vcpu-start-from-el2

On the first site,he says :

> can be enabled by "-M virt,accel=kvm,virtualization=on" when starting a VM

Good,I could try,but I'm not using qemu directly (I've installed qemu vers. 9) ,but 
virt-manager version 4.0. Maybe I should upgrade it ?

In virt-manager I don't see how I can specify those parameters.
Anyway I'm not sure that it will work,because on the second thread he said to :

-append "kvm-arm.mode=nested" \

Where is the truth ?

Very thanks.
