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.

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.

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.

Host. Does the issue only exist on the Westmere CPU?

Yes. All E5 Xeons v1, v2, v3 are working fine and i've never seen this message.

one while booting:

[    0.811645] Switched APIC routing to physical x2apic.

Westmere doesn't have the x2apic support. It is strange to see it here. Can you try to disable x2apic manually on you Qemu cmdline?
