You can patch it on guest kernel,
https://git.kernel.org/cgit/linux/kernel/git/tip/tip.git/commit/?id=73fdeb66592ee80dffb16fb8a9b7378a00c1a826,
although the warning has no effect on your guest.

it's just warning, current KVM does not support intel PT feature, you can
ignore it, and I will fix the warning in native kernel.
