the options reported here:
appear when I use the player under windows but not under linux.
I need to be able to set at least "Intel VT-x/EPT or AMD-V/RVI" but in this screen the only option available is related to the counters.
Can you help me to use nested virt even under linux, please?
The "Preferred Mode" dropdown is no longer available starting from version 14. It will use Intel VT-x/EPT (or AMD-V/RVI) automatically for the VM. Binary translation for VM execution and software-based shadowing for virtual RAM management was removed from version 14.
If Hyper-V is enabled on the Windows host, starting from version 15.5.5, power up of VM will fail if either "Virtualize Intel VT-x/EPT ir AMD-V/RVI" is enabled or "Virtualize CPU performance counters" is enabled. This is because the ring 3 User Level Monitor (ULM) that uses the Windows Hypervisor API is the virtual machine monitor instead of the usual ring 0 VMM.
After different attempts, I figure out that this option is not available during the creation of the VM, but after created that, I have the options enabled.
I'm running android studio in a Ubuntu VM 20.04.
The problem now is the performance: in my Fedora 32, with i7 and 16 GB of ram the emulator started by android studio is too slow.
I changed my laptop due to android studio running on my physiscal machine. It seems that I have to change it again for android studio but this time inside a VM. Too bad.
For nested virtualisation, it is best to have at least Haswell generation (4th gen Core) or newer. For laptop CPUs, it gets a little bit trickier as not all Haswell virtualisation features that are good for running nested VMs are available in all models.
