This API call sets maximum tolerable time for which the domain is allowed to be paused at the end of live migration. It's supposed to be called while the domain is being live-migrated as a reaction to migration progress.
Changes in version 3: - use milliseconds instead of nanoseconds both internally and in API - correct suffix for qemu monitor commands
Changes in version 2: - API renamed to reflect it's maximum downtime - new flags parameter for the future - qemu implementation was fixed so that the call is allowed iff the domain is being migrated - --downtime parameter of virsh migrate command was removed in favor of new virsh migrate-setmaxdowntime which can be run independently - virsh accepts downtime as nanoseconds instead of floating-point seconds (shells don't deal with floating-point numbers well)
ACK,
looks fine to me now !
Ah, I forgot to send a note here... I fixed virDomainMigrateSetMaxDowntime implementation in qemu driver to complain in case flags != 0 and pushed the patchset on Friday. Jirka
