Can't install KVM in Qubes OS?

[Tae Hwan Kim]

Hello!

I need to install KVM for mobile development.(for android emulator).

so I did try installing kvm like this

sudo dnf -y install qemu-kvm libvirt virt-install bridge-utils

but my app vm shows me error like this.

Error:

(try to add '--allowerasing' to command line to replace conflicting packages or '--skip-broken' to skip uninstallable packages)

I read that Qubes os using XEN over KVM. So I can't install KVM? I am just asking before do any further action because I am worried about breaking my app vm.

Qubes-os uses xen, not kvm. Nested virtualization is disabled because of the added attack surface.

Ive installed qemu in a debian template in the past, but have not tried recently. instead i have another machine running kvm with nested virtualization enabled and run vagrant remotely on that one using virt-manager for desktop vms. 

I was also able to get the andrioid emulator running on just qemu, but that was painfully slow. Hope they make a container option. this was a couple years ago.
