[Serge Hallyn]

This package is causing a regression in lp:qa-regression-testing's
scripts/test-qemu.py.

I'm running the testcase one more time (after having verified that the
current package did not suffer the same failure), then I'm going to mark this
verification-failed.

Hm, a second run did not reproduce the error.  If I can't get it to
happen again in a few hours of re-trying, I'll assume it was a fluke or
related to the host.

I could not reproduce the original issue, but the new qemu packages
appear to be regression-free, so marked this verification-done on that
grounds.  If the SRU team prefers to kick this package I'm ok with that
as well.

[Chris J Arges]

Hello Li, or anyone else affected,

Accepted qemu into trusty-proposed. The package will build now and be
available at https://launchpad.net/ubuntu/+source/qemu/2.0.0+dfsg-
2ubuntu1.20 in a few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to
enable and use -proposed.  Your feedback will aid us getting this update
out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, and change the tag
from verification-needed to verification-done. If it does not fix the
bug for you, please add a comment stating that, and change the tag to
verification-failed.  In either case, details of your testing will help
us make a better decision.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

[Stefan Bader]

@Li Chengyuan, thank you for the clarification. So just formally I will
mark the Precise task of this report as invalid (since the qemu in
Precise is actually a different source package and also not affected as
far as I can tell). I will need to figure out how to ensure this fix is
also pulled into the cloud-archive after it landed in the Trusty/Vivid
main archive.

[Stefan Bader]

Just saw kernel version 3.2 mentioned. So this seems to be a mix of
older base OS (Precise) and a more recent qemu (maybe from Trusty). I am
trying to clarify how far this needs to be backported. So I think the
original qemu version in Precise is unaffected.

[Stefan Bader]

@Li Chengyuan, is your host OS really 12.04 (aka Precise)? Because in
12.04 the qemu version is 1.0 and the fix would not apply. I am not sure
that old qemu is even affected since the code is very different.
Backports of the fix seem only to make sense up (or back) to 14.04 (aka
Trusty) which would also match the qemu version 2.0 which you mentioned.

[Qemu-devel] [Bug 1465935] Re: kvm_irqchip_commit_routes: Assertion `ret == 0' failed

[Stefan Bader]

SRU Justification:

Impact: Moving around interrupt handling on SMP (like irqbalance does)
in qemu instances can cause the qemu guest to crash due to an internal
accounting mismatch.

Fix: Backported patch from upstream qemu

Testcase: See above. Verified for Trusty with provided test qemu
package(s).

Bader,

Sorry to response late. 
We patch our QEMU 2.0 and running on ubuntu 12.04, and shall keep it running 
for a while. 
I'll let you know if this problem is gone after weeks.

Regards,
CY.

[Stefan Bader]

Unfortunately I seem to be unable to get this bug triggered with the 
reproducer. It could be a detail of the guest setup I am missing. Since I do 
not have access to RHEL I used CentOS 6.3 in a 8core guest with 2 virtio disks. 
Host was 14.04. Left the script running for quite a bit but no crash happened.
So it would be up to you to confirm that with a current 14.04 host you still 
can trigger the bug and with the patched version of qemu from 
http://people.canonical.com/~smb/lp1465935/ it would be gone. Thanks.

The proposed fix seems not yet part of any qemu release but applied as

commit bdf026317daa3b9dfa281f29e96fbb6fd48394c8
Author: 马文霜 kevin...@tencent.com
Date:   Wed Jul 1 15:41:41 2015 +0200

Fix irq route entries exceeding KVM_MAX_IRQ_ROUTES

to v2.4.0-rc0. So this would affect all current releases and the current
development release (Wily/15.10). I would start there with
reproduction/verification and work backwards from there.

Subject: Re: [Qemu-devel] [PATCH] Fix irq route entries exceed 
KVM_MAX_IRQ_ROUTES

On 30/06/2015 05:47, Li, Chengyuan wrote:
 Here is my understanding,
 
 1) why isn't the existing check in kvm_irqchip_get_virq enough to fix 
 the bug?
 
 From kvm_pc_setup_irq_routing() function, we can see that 15 routes 
 from PIC and 23 routes from IOAPIC are added into irq route table, but 
 only
 23 irq(gsi) are reserved. This leads to irq route table has been full 
 but there are still 15 free gsi. So the retry part of
 kvm_irqchip_get_virq() shall never have chance to be executed.
 
 2) If you introduce this extra call to kvm_flush_dynamic_msi_routes, 
 does the existing check become obsolete?
 
 As gsi_count is the max number of irq route table, if below code is 
 merged, then existing check is obsolete and can be removed.
 
 +if (!s-direct_msi  s-irq_routes-nr == s-gsi_count) {
 +kvm_flush_dynamic_msi_routes(s);
 +}
 
 Please let me know if you have some other comments for the patch? Thanks!

Thanks for finally clearing up my doubts about the patch!  I'll apply it
soon.

[Qemu-devel] [Bug 1465935] Re: kvm_irqchip_commit_routes: Assertion `ret == 0' failed

[Li Chengyuan]

From the debug log, we can see that virq is only 1008, but irq route table has 
been full, i.e. 1024. 
In kvm_irqchip_get_virq(), it only calls kvm_flush_dynamic_msi_routes() when 
all virqs(total gsi_count, 1024 too) have been allocated,  but irq route table 
has two kind of entry type,  KVM_IRQ_ROUTING_IRQCHIP and KVM_IRQ_ROUTING_MSI. 
Seems that 16 KVM_IRQ_ROUTING_IRQCHIP entries has been reserved, if max 
gsi_count is still 1024, then irq route table is possible to be overflow.
The fix could be either set gsi_cout=1008 or increase max irq route count to 
1040.

kvm_irqchip_send_msi, virq=1008, nr=1024
kvm_irqchip_commit_routes, ret=-22
kvm_irqchip_commit_routes, irq_routes nr=1024
