Guys thanks a lot for taking the time out to reply, Although adding the $PATH & symbolic link methods both solved the "No hypervisor found" error on virt-manager but when I try to create a VM using the wizard it says:

"No hypervisor options were found for this connection"

"This usually means that QEMU or KVM is not installed on your machine, or the KVM modules are not loaded."

The QEMU I want to connect to libvirt has no KVM kernel drivers (DPDK Qemu). There is a single binary "qemu-system-x86_64"

I am using virt-manager GUI to see whether qemu is being detected by libvirt or not (is there a better/CLI method?)

Actually we will search through $PATH for QEMU binaries, so if you
install somewhere unusual, just make sure libvirtd sees an updated
$PATH env variable including the new location.
