Silently ignored flags get in the way of new features that
use those flags.
Regarding ESX migration flags - right now, ESX silently enforces
VIR_MIGRATE_PERSIST_DEST, VIR_MIGRATE_UNDEFINE_SOURCE, and
VIR_MIGRATE_LIVE, even if those flags were not supplied; it ignored
other flags. This patch does not change the implied bits (it permits
but does not require them), but enforces only the supported bits.
If further cleanup is needed to be more particular about migration
flags, that should be a separate patch.
It turns out that libvirt.c also handles (or at least claims to handle)
VIR_MIGRATE_PAUSED on behalf of ESX, so I'm squashing this in:
diff --git i/src/esx/esx_driver.c w/src/esx/esx_driver.c

libvirt.c also handles VIR_MIGRATE_PEER2PEER and VIR_MIGRATE_TUNNELLED,
but only if the driver advertises those features, which ESX does not.
So by the time the ESX callbacks are reached, those flag bits can never
be set.
ACK.
I've pushed this now.
