OK, I was able to reproduce with that version after 792 attempts. Using
a newer version, I was unable to reproduce in over 33,000 attempts.
Since this does not impact a version of qemu-efi in any supported Ubuntu
release, I'll mark invalid.
** Also affects: fedora via
Correction, marking Invalid for qemu - but Fix Released for qemu-efi,
since it likely did impact 0~20150106.5c2d456b-2 back when that was a
current version.

To manage
I've got a system setup w/ a config as close to yours as I could, and
I'm running VM start/stop loops to try and reproduce this problem. No
luck so far, but I'm at just over 100 attempts at this point. One
question - what version of qemu-efi are you using? It is possible that
the bug lies there
One more, still with the "load/store instruction decoding not
implemented" kernel message.
LC_ALL=C PATH=/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/sbin:/sbin:/bin
QEMU_AUDIO_DRV=none /usr/bin/kvm -name instance-00166b4b -S -machine
virt,accel=kvm,usb=off -cpu host -bios
One more. The "load/store instruction decoding not implemented" is still
here.
LC_ALL=C PATH=/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/sbin:/sbin:/bin
QEMU_AUDIO_DRV=none /usr/bin/qemu-system-aarch64 -name instance-001613c8 -S
-machine virt,accel=kvm,usb=off -cpu host -bios
And again. The "load/store instruction decoding not implemented" is
still here.
LC_ALL=C PATH=/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/sbin:/sbin:/bin
QEMU_AUDIO_DRV=none /usr/bin/qemu-system-aarch64 -name instance-0015c4f9 -S

Hi,
It happened again, with the "load/store instruction decoding not
implemented" in the log.
LC_ALL=C PATH=/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/sbin:/sbin:/bin
QEMU_AUDIO_DRV=none /usr/bin/qemu-system-aarch64 -name instance-0015baf9 -S
-machine virt,accel=kvm,usb=off -cpu host -bios
This is highly correlated with pause-on-start. I can't say 100% because
I haven't look at kern.log for all the Paused instances (and I'm not
sure I can correlate this easily now), but every time I looked it was
there.
And it's definitely not there during normal startups.

Thanks Junien. Is that correlated with the pause-on-start, or does that
appear in dmesg on normal startups as well?

It looks like the kernel is returning -ENOSYS. Are there any messages in
dmesg coinciding with this event?

This just happened again with qemu 1:2.5+dfsg-5ubuntu10.7~cloud0

The issue would also appear in second level virtualization which this is
not right?

Hi Junien,
I've seen issues like that but they were fixed in qemu 2.3 which you have
(https://bugzilla.redhat.com/show_bug.cgi?id=1213478).
In general I wonder where you actual qemu comes from, Trusty is on 2.0
and the closest would be UVA-Liberty with 1:2.3+dfsg-5ubuntu9.4~cloud2,
so what kind
Status changed to 'Confirmed' because the bug affects multiple users.
