No. A hypervisor uses the host CPU's virtualization extensions
to allow the guest code to run directly on the host CPU. This
is why they're fast. This also means that they only work when
the guest CPU is the same architecture as the host CPU.
So you can run an x86 OS on an x86 host CPU, or an Arm
OS on an Arm host CPU using a hypervisor, but you can't run
a guest of the "wrong" architecture.
