I do see the same behavior on v5.2-rc1 where hiding the pmu from L1 breaks nested virtualization, but manually reverting both commits doesn't change that for me, i.e. there's another bug lurking, which I'll start hunting. Any chance the successful test used a different command line or something? -- You are receiving this mail because: You are watching the assignee of the bug.
