Public bug reported:
I am running Arch linux
vanilla 4.7.2 kernel
qemu 2.7
libvirt 2.2.0
virt-manager 1.4.0
Since the upgrade from qemu 2.6.1 to 2.7 a few days ago. I'm no longer
able to PXE boot at all. Everything else appears to function normally.
Non PXE booting and everything else is perfect. Obviously have
restarted everying etc. Have tried the various network drivers also.
This occurs on domains created with 2.6.1 or with 2.7
When I choose PXE boot, the machine moves to a paused state (crashed)
immediately after the 'starting PXE rom execution...' message appears.
Reverting to qemu 2.6.1 package corrects the issue.
The qemu.log snippet follows below.
I'm not sure how to troubleshoot this problem to determine if it's a
packaging error by the distribution or a problem with qemu/kvm/kernel?
Any help would be much appreciated - Thanks,
Greg

Without -enable-kvm, the above command work perfectly. I can PXE boot
from the tftp server on my LAN just fine.
When KVM is enabled, qemu crashes immediately displaying only this:
Booting from ROM...

I can confirm the issue, I stumbled upon it on a Proxmox system using
the pve-qemu-kvm package versions 2.7.0-3 + 2.7.0-4 and have reported
the bug in Proxmox bug tracker as
https://bugzilla.proxmox.com/show_bug.cgi?id=1182 with further details.
I was able to reproduce the problem also with latest git of qemu:
% ./qemu-system-x86_64 -version
QEMU emulator version 2.7.50 (v2.7.0-1343-g4429532-dirty)
When disabling the KVM feature QEMU loads fine with iPXE/PXE boot.
I'd be happy to provide further information if needed.

Can you post the host dmesg that is written at the time of the guest
crash?

Bug description:
I am running Arch linux
vanilla 4.7.2 kernel
qemu 2.7
libvirt 2.2.0
virt-manager 1.4.0
Since the upgrade from qemu 2.6.1 to 2.7 a few days ago. I'm no longer
able to PXE boot at all. Everything else appears to function normally.
Non PXE booting and everything else is perfect. Obviously have
restarted everying etc. Have tried the various network drivers also.
This occurs on domains created with 2.6.1 or with 2.7
When I choose PXE boot, the machine moves to a paused state (crashed)
immediately after the 'starting PXE rom execution...' message appears.
Reverting to qemu 2.6.1 package corrects the issue.
The qemu.log snippet follows below.
I'm not sure how to troubleshoot this problem to determine if it's a
packaging error by the distribution or a problem with qemu/kvm/kernel?
Any help would be much appreciated - Thanks,
Greg

The ipxe bisection is extremely helpful; can you please thank Peter
Pickford in the arch tracker on our behalf?
So, the culprit iPXE commit is
commit 71560d185475117b10994d839afe059577e7768c
Author: Michael Brown <mcb30@ipxe.org>
Date: Wed Apr 27 11:03:18 2016 +0100
[librm] Preserve FPU, MMX and SSE state across calls to virt_call()
We have actually seen this, in
https://bugzilla.redhat.com/show_bug.cgi?id=1356762
This is a feature gap in KVM's instruction *emulation*.
In one of the previous comments, I asked for the KVM module parameters /
settings -- I'm pretty sure that once you upload them, they will match
Paolo's RHBZ comment in
<https://bugzilla.redhat.com/show_bug.cgi?id=1356762#c12>.
Namely, I expect that the affected host does not support
"unrestricted_guest"; i.e., it cannot natively virtualize the FXSAVE
instruction (in big real mode that iPXE runs in). Given that
"emulate_invalid_guest_state" is set to "yes" on your host (well, I
expect that at least; I think it's the default if unrestricted_guest is
missing), KVM "manually" emulates 16-bit big real mode for iPXE.
However, FXSAVE emulation is missing from KVM.
RHBZ#1356762 is the bug that tracks the Request for Enhancement.

Gerd, do you think we should rebuild the iPXE binaries bundled with QEMU
with the offending iPXE commit (71560d185475) reverted, at least until
KVM gets FXSAVE emulation in big real mode? I think this would be
reasonable, as that iPXE commit works around a bug in the IBM Tivoli
Provisioning Manager VMM.
(In other words, the iPXE commit that breaks QEMU's bundled binaries,
for a number of KVM users, targets a hypervisor that's different from
QEMU/KVM/Xen -- thus normally we wouldn't care about that commit at
all.)
Thanks.

qemu 2.7 / iPXE crash

Bug description:
I am running Arch linux
vanilla 4.7.2 kernel
qemu 2.7
libvirt 2.2.0
virt-manager 1.4.0
Since the upgrade from qemu 2.6.1 to 2.7 a few days ago. I'm no longer
able to PXE boot at all. Everything else appears to function normally.
Non PXE booting and everything else is perfect. Obviously have
restarted everying etc. Have tried the various network drivers also.
This occurs on domains created with 2.6.1 or with 2.7
When I choose PXE boot, the machine moves to a paused state (crashed)
immediately after the 'starting PXE rom execution...' message appears.
Reverting to qemu 2.6.1 package corrects the issue.
The qemu.log snippet follows below.
I'm not sure how to troubleshoot this problem to determine if it's a
packaging error by the distribution or a problem with qemu/kvm/kernel?
Any help would be much appreciated - Thanks,
Greg

We could also try changing upstream iPXE so that the FXSAVE trick is not
active for CONFIG=qemu.

BTW, this bug can be easily reproduced on hosts that do feature
unrestricted_guest, just reload the kvm_intel module with

qemu 2.7 / iPXE crash
Status in QEMU:

Bug description:
I am running Arch linux
vanilla 4.7.2 kernel
qemu 2.7
libvirt 2.2.0
virt-manager 1.4.0
Since the upgrade from qemu 2.6.1 to 2.7 a few days ago. I'm no longer
able to PXE boot at all. Everything else appears to function normally.
Non PXE booting and everything else is perfect. Obviously have
restarted everying etc. Have tried the various network drivers also.
This occurs on domains created with 2.6.1 or with 2.7
When I choose PXE boot, the machine moves to a paused state (crashed)
immediately after the 'starting PXE rom execution...' message appears.
Reverting to qemu 2.6.1 package corrects the issue.
The qemu.log snippet follows below.
I'm not sure how to troubleshoot this problem to determine if it's a
packaging error by the distribution or a problem with qemu/kvm/kernel?
Any help would be much appreciated - Thanks,
Greg

Thanks. It's indeed the same issue, you have unrestricted_guest=N and
emulate_invalid_guest_state=Y.

The iPXE patches are now upstream (a big "thank you" to the iPXE
maintainer!); QEMU 2.8 -- with Gerd willing -- should bundle iPXE
binaries containing that fix.

qemu 2.7 / iPXE crash
Status in QEMU:
In Progress
Bug description:
I am running Arch linux
vanilla 4.7.2 kernel
qemu 2.7
libvirt 2.2.0
virt-manager 1.4.0
Since the upgrade from qemu 2.6.1 to 2.7 a few days ago. I'm no longer
able to PXE boot at all. Everything else appears to function normally.
Non PXE booting and everything else is perfect. Obviously have
restarted everying etc. Have tried the various network drivers also.
This occurs on domains created with 2.6.1 or with 2.7
When I choose PXE boot, the machine moves to a paused state (crashed)
immediately after the 'starting PXE rom execution...' message appears.
Reverting to qemu 2.6.1 package corrects the issue.
The qemu.log snippet follows below.
I'm not sure how to troubleshoot this problem to determine if it's a
packaging error by the distribution or a problem with qemu/kvm/kernel?
Any help would be much appreciated - Thanks,
Greg

When I choose PXE boot, the machine moves to a paused state (crashed)
immediately after the 'starting PXE rom execution...' message appears.
Reverting to qemu 2.6.1 package corrects the issue.
The qemu.log snippet follows below.
I'm not sure how to troubleshoot this problem to determine if it's a
packaging error by the distribution or a problem with qemu/kvm/kernel?
Any help would be much appreciated - Thanks,
Greg
