OK, so you need nested virtualisation. That's not supported in
code-translation mode, only when you're using the KVM kernel module.
The message you got was about the simulated CPU, not your host.
If you can enable KVM, qemu will pass through your host to the
Looks like you have the kernel packages installed, now you need to
make sure that:
1, The version of qemu you're using supports KVM, and
2. you have permissions to use KVM.
The first is easy. On Debian-derived systems (debian, ubuntu, mint,
sudo apt install qemu-kvm
should do the trick. Similarly
sudo yum install qemu-kvm
on Redhat-derived systems.
The second is a little harder. Do
ls -l /dev/kvm
You'll see something like
crw-rw----+ 1 root kvm 10, 232 Jun 30 09:13 /dev/kvm
if kvm is installed. The second username (in this case, 'kvm') is the
group you need to be in. Do
sudo useradd your-login kvm
(replacing 'kvm' with the actual group /dev/kvm is in, and
'your-login' with you local login name.)
qemu-system-x86_84 -enable-kvm should then work.
