Which kernel are you using on the physical host?

I am seeing this (almost the same Code line) on 4.20.5 kernel. 4.19.11
works fine.

In my case the code is Code=cb 66 ba 52 d0 0f 00 e9 cb fe bc 00 80 0a 00 e8 0e

Yes. I was using a 4.20.x kernel. But i guess the bug can be closed
because the vm does not exist anymore and the new one does not show this
behaviour.

Note the error here is on stderr of L1's qemu; there's nothing in dmesg

[Qemu-devel] [Bug 1813165] Re: KVM internal error. Suberror: 1 emulation failure

2019-02-11 Thread Laszlo Ersek (Red Hat)

This is related to SMM usage in SeaBIOS. The QEMU register dump states
SMM=1, plus "<0f> aa" from the dumped code stands for the RSM
instruction (0F AA -- RSM—Resume from System Management Mode, see it in
the Intel SDM.)

In RHEL7 downstream, we disabled SMM usage in SeaBIOS.
- https://bugzilla.redhat.com/show_bug.cgi?id=1378006
- https://bugzilla.redhat.com/show_bug.cgi?id=1464654#c21

It's conceivable that the upstream host kernel suffered a regression
4.19 and 4.20; in particular when it comes to nesting. For example, Ladi
fixed  in
:

0234bf885236 KVM: x86: introduce ISA specific SMM entry/exit callbacks
72d7b374b14d KVM: x86: introduce ISA specific smi_allowed callback
21f2d5511838 KVM: nVMX: set IDTR and GDTR limits when loading L1 host state
72e9cbdb4338 KVM: nVMX: fix SMI injection in guest mode
c26340651b75 KVM: nSVM: refactor nested_svm_vmrun
05cade71cf3b KVM: nSVM: fix SMI injection in guest mode

These were part of v4.15. But, based on
, more recent
kernels may have regressed those fixes.

(Bunch of non-public BZ references above; sorry about that, I can't open
them up.)

[Qemu-devel] [Bug 1813165] Re: KVM internal error. Suberror: 1 emulation failure

2019-02-11 Thread Albert Damen

I have bisected the kernel and ended with first bad commit:

commit 14c07ad89f4d728a468caaea6a769c018c2b8dd6
Author: Vitaly Kuznetsov 
Date:   Mon Oct 8 21:28:08 2018 +0200

x86/kvm/mmu: introduce guest_mmu

When EPT is used for nested guest we need to re-init MMU as shadow
EPT MMU (nested_ept_init_mmu_context() does that). When we return back
from L2 to L1 kvm_mmu_reset_context() in nested_vmx_load_cr3() resets
MMU back to normal TDP mode. Add a special 'guest_mmu' so we can use
separate root caches; the improved hit rate is not very important for
single vCPU performance, but it avoids contention on the mmu_lock for
many vCPUs.

It seems to me this is some timing issue. If a L2 vm fails to start I
can get it running with a few hard reboots.

Also changing the L2 config helps, -net none, -nodefaults and -vga
cirrus let the vm start most of the time.

Ack, thanks for the bisect! It seems something was overlooked when we
did host/guest mmu split. I'll try to investigate.

2019-02-20 Thread Vitaly Kuznetsov

Thomas, Albert, David,

I'm having hard times trying to reproduce the issue in my environment;
could you please provide your qemu command lines for both L0 and L1? It
would also be great if you could try to come up with some 'minimal'
configuration (my guess is that in L1 having just "qemu-system-x86_64
-machine q35,smm=on,accel=kvm -cpu host -vnc :0" would do).

Thanks!
