There are extra properties for accelerators to enable the specific features. For example, the dirty ring for KVM accelerator can be enabled by "-accel kvm,dirty-ring-size=65536". Unfortuntely, the extra properties for the accelerators aren't supported. It makes it's impossible to test the combination of KVM and dirty ring as the following error message indicates. # cd /home/gavin/sandbox/kvm-unit-tests/tests # QEMU=/home/gavin/sandbox/qemu.main/build/qemu-system-aarch64 \ ACCEL=kvm,dirty-ring-size=65536 ./its-migration : BUILD_HEAD=2fffb37e timeout -k 1s --foreground 90s /home/gavin/sandbox/qemu.main/build/qemu-system-aarch64 \ -nodefaults -machine virt -accel kvm,dirty-ring-size=65536 -cpu cortex-a57 \ -device virtio-serial-device -device virtconsole,chardev=ctd -chardev testdev,id=ctd \ -device pci-testdev -display none -serial stdio -kernel _NO_FILE_4Uhere_ -smp 160 \ -machine gic-version=3 -append its-pending-migration # -initrd /tmp/tmp.gfDLa1EtWk qemu-system-aarch64: kvm_init_vcpu: kvm_arch_init_vcpu failed (0): Invalid argument Allow to specify extra properties for accelerators. With this, the "its-migration" can be tested for the combination of KVM and dirty ring.
