[PATCHv2 4/6] maint: clean up error reporting in migration

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The choice of error message and category was not consistent
in the migration code; furthermore, the use of virLibConnError
is no longer necessary now that we have a generic virReportError.

* src/qemu/qemu_migration.c (virDomainMigrate*): Prefer
virReportError over virLibConnError.
