AMD Ryzen 7 2700U virtualization not detected

I have tried both R4.0.3 and R 4.0.4-rc1 with my AMD Ryzen 7 2700U processor. I have virtualization checked as Enabled in BIOS. On my current Linux install, in /proc/cpuinfo I have the svm flag. VirtualBox works with AMD-V nesting. But whenever I try to install Qubes, I get the incompatibility error during the initialization of the installer saying my hardware does not support virtualization. I tried installing Qubes anyway and skipping the error, but after boot I can’t launch any VM because I keep getting the message that virtualization is off. What can I do?

Hi @sushilord,

My first idea is a bad BIOS/UEFI setting.

I hope that one of the above lines will help you.
