Hi all, we just started a test with Jailhouse in a VM on a decently recent Intel box. It has APICv / posted interrupts support. And it breaks Jailhouse activation (L1 breakage, host seems to be fine). Loading kvm-intel with enable_apicv=0 resolves the issue. Henning started to debug from Jailhouse POV and found out it may be NMI IPI related. We will try to dig deeper, but any support is welcome regarding the APICv specialties. Could this also explain some of the incompatibilities you found, Yang? Maybe you want to check if more hypervisor work when APICv is off.
I will check it tomorrow. ;-) Regards, Wanpeng Li
