This subject is discussed in the Support post Trouble running Qubes on KVM/QEMU, where it got a negative answer :

I tried running Qubes on KVM/QEMU, but it didn’t work. Is it even possible to do that? I just want to test the OS without reformatting the whole computer.

The answer was a quote from the Qubes OS Installation Guide :

Note: Qubes OS is not meant to be installed inside a virtual machine as a guest hypervisor. In other words, nested virtualization is not supported. In order for a strict compartmentalization to be enforced, Qubes OS needs to be able to manage the hardware directly.

The final advice was :

Your options are:

  • Install on another (external) drive
    • Bear in mind that if your external drive is a USB drive, you won’t be able to take advantage of USB passthrough. Qubes OS will implode if you do that. (No, this is not a Qubes OS vulnerability, as Qubes OS is not designed to run this way. It’s the equivalent of removing the internal boot drive once the machine has already booted.)
  • Get a cheap computer to try it on
    • Make sure that it’s a 64-bit X86 CPU that has VT-x and VT-d in its instruction set, otherwise it won’t boot.

An option that wasn't discussed is to install Qubes OS to a separate partition on the hard disk in dual-boot, but you might there be taking risks with your current installation.
