What is the host kernel version and host dmesg information? And does
the problem exist when you use latest kernel and QEMU to replace old
binary file?

Guest and Host is both 4.1.15. You mean the complete dmesg output from host?
What do you mean with replace old binary file? I haven't tested Kernel
4.4 as we use 4.1 as it is a long term stable kernel release.

Have you seen this before? I mean use the old KVM like 3.10?

Guest or host? To test with a guest would be quite easy. Downgrading the
host is very difficult not sure if the hw is supported.
