Hi Andrew, I have tested your patch on kernel- 5.2.7 + QEMU (4.0.94 + patch).
This patch series works fine for my tests when use qemu-system-aarch64 directly. But I can't startup kvm when I use virsh[1]. Command I executed. # virsh start test1 The error message is [internal error: CPU features not supported by hypervisor for aarch64 architecture.] Do you have any ideas for this error?
