[Bug 1536331] Re: Precise to Trusty live migration failing
OTOH it might be good that I set up all these combinations already before thinking of kvm-ipxe-precise - that provided good coverage now :-) So with that set up and kvm-ipxe-precise installed on the target I get this combination of test results. Always keeping the combination of qemu/libvirt that belonged together - so old means qemu&libvirt of the 1374612 fix, while new is as of today. Define: P(old) libvirt 0.9.8-2ubuntu17.19 qemu 1.0+noroms-0ubuntu14.18 P(new) libvirt 0.9.8-2ubuntu17.23 qemu 1.0+noroms-0ubuntu14.30 T(old) libvirt 1.2.2-0ubuntu13.1.6 qemu 2.0.0+dfsg-2ubuntu1.6 T(new) libvirt 1.2.2-0ubuntu13.1.19 qemu 2.0.0+dfsg-2ubuntu1.28 T(no alias) libvirt 1.2.2-0ubuntu13.1.19 qemu 2.0.0+dfsg-2ubuntu1.29 .29 is a local build dropping the double alias in Trusty qemu Testing migrations types: converted-to-pc-1.0 / created-as-pc-1.0 / pc-1.0-qemu-kvm P(old) -> T(old): working / working / fail P(old) -> T(new): working / working / fail P(new) -> T(new): working / working / fail P(new) -> T(no alias): working / working / working So it seems not to be a regression at least. Instead back then fixing the migration of the former default pc-1.0 type it was missed, that the newly introduced pc-1.0-qemu-kvm/pc-1.0-precise did not migrate. That would also explain why things calmed down (all former started guests migrated fine). But later then reports came in - as the later started guests got the new pc-1.0-qemu-kvm type by default. Fortunately it seems that dropping the false alias in Trusty fixes the migration for all cases. Building that in a ppa now and preparing for a wider migration test run (e.g. from T->X with that) using my migration testsuite at https://code.launchpad.net/~ubuntu-server/ubuntu/+source/qemu-migration-test/+git/qemu-migration-test/+ref/master ppa builds will be in https://launchpad.net/~paelzer/+archive/ubuntu /qemu-machine-type-dev -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1536331 Title: Precise to Trusty live migration failing To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1536331/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1536331] Re: Precise to Trusty live migration failing
I tried setting pc-1.0 on the migration source as type as suggested by Serge.
But that didn't get it running for me with the current 14.30 verison.
Doing so with 1.0+noroms-0ubuntu14.18 on built locally and inserted into the
test container.
But I still see the same migration failure - default machien types look the
same as with 14.30.
I spawned "new" guests on 14.18 with default pc-1.0-qemu-kvm and pc-1.0 - but
all those failed as well.
Then as Serge I also tried rebuilding qemu on Trusty without that double alias.
Still having 14.18 on the source I tried to migrate all three guests I had
already (created with 14.30 modified to pc-1.0, created with 14.18 and created
as pc-1.0 with 14.18) again, but they all fail.
I wanted to make sure my overall setup at least worked with the last known good
states.
And last good state is what was published for bug 1374612.
P: 1.0+noroms-0ubuntu14.18
T: 2.0.0+dfsg-2ubuntu1.6
To ensure we cover all qemu packages installed with:
apt-get install $(dpkg -l '*qemu*' | awk '/ii qemu/
{printf("%s=2.0.0+dfsg-2ubuntu1.6 ", $2)}')
apt-get install $(dpkg -l '*qemu*' | awk '/ii qemu/
{printf("%s=1.0+noroms-0ubuntu14.18 ", $2)}')
That would be exactly the combination that the old bug was verified with.
But even that was failing as well for me.
To round things up I checked which libvirt versions where active back then and
prepared matching old libvirt packages as well.
P: 0.9.8-2ubuntu17.19
T: 1.2.2-0ubuntu13.1.6
Note: has to be build with DEB_BUILD_OPTIONS="nocheck" these days.
apt-get install $(dpkg -l '*libvirt*' | awk '/ii libvirt/
{printf("%s=0.9.8-2ubuntu17.19 ", $2)}')
apt-get install $(dpkg -l '*libvirt*' | awk '/ii libvirt/
{printf("%s=1.2.2-0ubuntu13.1.6 ", $2)}')
This still failed to migrate any of my three guests.
I was afraid I might miss something obvious and checked my setup once more.
And I was right and found that kvm-ipxe-precise is not installed as it is only
a suggest on Trusty.
That could explain my failures, trying with that installed next.

[Bug 1536331] Re: Precise to Trusty live migration failing
I was analyzing the case for myself now, here my notes as documentation. The default type in Precise is (now): pc-1.0-qemu-kvm The logic in Trusty's libvirt to receive is in src/qemu/qemu_migration.c: IF TYPE = pc-1.0 && allow_incoming_qemukvm THEN SET TYPE => pc-1.0-precise But as shown above the type is pc-1.0-qemu-kvm in Precise, so the upper logic doesn't apply This is in patch: debian/patches/define-qemu-kvm-mt In since 1.0+noroms-0ubuntu14.18 due to LP: #1374612 That would still be fine as on Precise pc-1.0-qemu-kvm is a type with alias pc-1.0-precise. So this is the Distribution specific type. Only Trusty has to agree on the definition of the type. On Trusty this seems wrong, here I see double pc-1.0-qemu-kvm: kvm -M ? | egrep '(precise|1.0)' pc-1.0-qemu-kvm Standard PC (i440FX + PIIX, 1996) (alias of pc-1.0) pc-1.0 Standard PC (i440FX + PIIX, 1996) pc-1.0-precise Standard PC (i440FX + PIIX, 1996) (alias of pc-1.0-qemu-kvm) pc-1.0-qemu-kvm Standard PC (i440FX + PIIX, 1996) One is the alias of pc-1.0, and one is a type on its own.

Old bug was bug 1291321 That was closed and passed regression testing and all that, but it seems something was lost. Quoting Serge from the old closed bug: "This doesn't really make sense, but the patch adding the pc-1.0-qemu-kvm machine type seems to be also adding pc-1.0-qemu-kvm as an alias for pc-1.0, all the way back to the original version where we introduced the patch. Which doesn't really make sense as the package did pass SRU testing. When I build a new package without that extra alias, the migration gets further, though it then stops on Unknown savevm section or instance 'kvm-tpr-opt' 0" We will keep the discussion in this bug - that is why I transferred the latest statement of Serge here. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1536331 Title: Precise to Trusty live migration failing To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1536331/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
