Public bug reported:
Running qemu-system-aarch64 leads to a high CPU consumption on windows
10.
Tested with qemu: 4.0.0-rc4 & 3.1.0 & 2.11.0
Command: qemu_start_command = [
qemu-system-aarch64,
"-pidfile",
target_path + "/qemu" + str(instance) + ".pid",
"-machine",
"virt",
"-cpu",
"cortex-a57",
"-nographic",
"-smp",
"2",
"-m",
"2048",
"-kernel",
kernel_path,
"--append",
"console=ttyAMA0 root=/dev/vda2 rw ipx=" + qemu_instance_ip + "/64 net.ifnames=0 biosdevname=0",
"-drive",
"file=" + qemu_instance_img_path + ",if=none,id=blk",
"-device",
"virtio-blk-device,drive=blk",
"-netdev",
"socket,id=mynet0,udp=127.0.0.1:2000,localaddr=127.0.0.1:" + qemu_instance_port,
"-device",
"virtio-net-device,netdev=mynet0",
"-serial",
"file:" + target_path + "/qemu" + str(instance) + ".log"
]
*The cpu consumption is ~70%.
*No acceleration used.
*This CPU consumption is obtained only by running the above command. No workload on the guest OS.

Looking through old bug tickets... is this still an issue with the latest version of QEMU? Or could we close this ticket nowadays?
Also, what guest operating systems were you running ?
