Subject: [PATCH] virsh migrate: Properly check for --parallel-connections
|
|
|
|
Ever since --parallel-connections option for virsh migrate was
|
|
introduced we did not properly check the return value of
|
|
vshCommandOptInt. We would set VIR_MIGRATE_PARAM_PARALLEL_CONNECTIONS
|
|
parameter even if vshCommandOptInt returned 0 (which means
|
|
--parallel-connections was not specified) when another int option which
|
|
was checked earlier was specified with a nonzero value.
|
|
|
|
Specifically, running virsh migrate with either
|
|
--auto-converge-increment, --auto-converge-initial, --comp-mt-dthreads,
|
|
--comp-mt-threads, or --comp-mt-level would set
|
|
VIR_MIGRATE_PARAM_PARALLEL_CONNECTIONS parameter and if --parallel
|
|
option was not used, libvirt would complain
|
|
|
|
error: invalid argument: Turn parallel migration on to tune it
|
|
|
|
even though --parallel-connections option was not used at all.
