What's your full command line?

This is mine:
qemu-system-x86_64 \
-drive if=virtio,file=/home/oc/VM/img/netbsd.image,index=0,media=disk \
-M q35,accel=kvm -m 350M -cpu host -smp $(nproc) \
-nic user,hostfwd=tcp::6665-:22,model=virtio-net-pci,ipv6=off -nographic

It is possible that you have to tweak the "M q35" parameter, if you 
moved from a previous version of qemu.

"qemu-system-x86_64 -M help" will give you all the possible values.
