Guoqiang, could you close this ticket? Yuxiating, I assume you are using APICv and also have "hv-vapic" in qemu cmdline. At this point, you can remove "hv-vapic" to work around this issue. Note that, APICv outperforms Hyper-V's synthetic MSRs; regardless of this b= ug, it is recommended to remove "hv-vapic" if KVM enables APICv. --=20 You may reply to this email to add a comment.
