If you're not intended to run nested VMs (which would make it 3-level nesting btw) you can try: '-cpu host,-vmx' The strange part is that we don't seem to mangle MSR_IA32_VMX_TRUE_EXIT_CTLS in QEMU. I bet it has something to do with VM_EXIT_ALWAYSON_WITHOUT_TRUE_MSR in KVM. >> > This is the commit record: >> > * c88f1ffc19 - (origin/master, origin/HEAD) Merge remote-tracking >> > branch 'remotes/kevin/tags/for-upstream' into staging (3 days ago) >> > <Peter Maydell> >> > |\ >> > | * 47e0b38a13 - block: Drop unused .bdrv_has_zero_init_truncate (3 >> > days ago) <Eric Blake> >> > | * dbc636e791 - vhdx: Rework truncation logic (3 days ago) <Eric Blake> >> > | * bda4cdcbb9 - parallels: Rework truncation logic (3 days ago) <Eric >> > Blake> >> > | * be9c9404db - ssh: Support BDRV_REQ_ZERO_WRITE for truncate (3 days >> > ago) <Eric Blake> >> > | * fec00559e7 - sheepdog: Support BDRV_REQ_ZERO_WRITE for truncate (3 >> > days ago) <Eric Blake> >> > | * 2f98910d5b - rbd: Support BDRV_REQ_ZERO_WRITE for truncate (3 days >> > ago) <Eric Blake> >> > >> > I run this qemu in a VM base on EXSi. >> > >> > Does anyone have the same issue? > > cc'ing in Vitaly since he knows VMWare stuff.
