I use virtme-ng, according to ps qemu gets called with:

/usr/local/bin/qemu-system-x86_64 -name virtme-ng -m 1G -fsdev local,id=virtfs5,path=/,security_model=none,readonly=on,multidevs=remap -device virtio-9p-pci,fsdev=virtfs5,mount_tag=/dev/root -machine accel=kvm:tcg -device i6300esb,id=watchdog0 -cpu host -parallel none -net none -echr 1 -chardev file,path=/proc/self/fd/2,id=dmesg -device virtio-serial-pci -device virtconsole,chardev=dmesg -chardev stdio,id=console,signal=off,mux=on 

-serial chardev:console -mon chardev=console -vga none -display none -smp 4 -kernel ./arch/x86/boot/bzImage -append virtme_hostname=virtme-ng nr_open=1073741816 virtme_link_mods=/home/virtme/testing-1/.virtme_mods/lib/modules/0.0.0 virtme_rw_overlay0=/etc virtme_rw_overlay1=/lib virtme_rw_overlay2=/home virtme_rw_overlay3=/opt virtme_rw_overlay4=/srv virtme_rw_overlay5=/usr virtme_rw_overlay6=/var virtme_rw_overlay7=/tmp console=hvc0 earlyprintk=serial,ttyS0,115200 virtme_console=ttyS0 psmouse.proto=exps virtme_chdir=home/virtme/testing-1 rootfstype=9p rootflags=version=9p2000.L,trans=virtio,access=any raid=noautodetect ro init=/home/virtme/virtme-ng/virtme/guest/virtme-init

QEMU version is 8.2.1 (built from source)
