[Qemu-devel] [Bug 391879] Re: migrate exec ignores exit status

[Dave Walker]

This is a bug and has been reported upstream, it is unlikely to be fixed
at the distribution level and therefore anyone interested in working on
this bug should contribute a patch to the upstream project.  This will
then filter down to Ubuntu when it is merged mainline.  Marking "Won't
Fix" against the Ubuntu package.

Thanks for reporting this bug.

Using

  migrate "exec:cat > foo; false"

in the monitor results in the state of the VM being written to foo, as expected, and the VM then being stopped. This is surprising, as I think it stands to reason that in case of a failed migrate-exec process, which is what a non-zero exit status implies to me, the VM should continue.

This bug appears to be filed against the Ubuntu qemu component,
rather than the upstream qemu component. Are we supposed to be
getting notifications for all Ubuntu distro qemu bugs too, rather
than just usptream bug reports ?

This bug is filed as affecting both the qemu-kvm package in Ubuntu, as
well as the QEMU project (upstream).

Activity in the bug is sent to subscribed parties of both the affected
package, and the affected project.

It's an upstream bug that references an Ubuntu bug.  Whenever a 
referenced bug has it's status changed, the upstream bug will be notified.

You can also reference bugs in just about any Bugzilla including the 
Fedora bugzilla which is pretty nice because then when a bug gets fixed 
in Fedora, you get an update in the Launchpad bug tracker.

Patch has been included here:
http://git.qemu.org/?p=qemu.git;a=commitdiff;h=41ef56e61153d7bd27d34a63463
So I assume this should be working now.
