Re: [libvirt] [PATCH] qemu: Make migration fail when port profile association fails on the dst host
On 03/27/2012 02:27 PM, Christian Benvenuti (benve) wrote:
In the current V3 migration protocol, Libvirt does not
check the result of the function
qemuMigrationVPAssociatePortProfiles
This means that it is possible for a migration to complete
successfully even when the VM loses network connectivity on
the destination host.
With this change libvirt aborts the migration
(during the "finish" step) when the above function fails, that
is to say when at least one of the port profile associations fails.

VIR_ERROR is logged, but not propagated back to the caller; besides,
'make syntax-check' warned that it was not a translated error message.
I'm applying this to convert to our preferred error reporting:

ACK with that fixed, so I added you to AUTHORS (let me know if you
prefer an alternate spelling), and pushed.
