The iSCSI block driver has ability to lookup various options, in
particular authentication info, specified by the separate -iscsi
argument. It currently uses the iSCSI IQN as the ID value for this
lookup, however, this does not work for common iSCSI IQNs as they
contain characters such as ':' which
The iSCSI block driver is a bit strange in that it requires a
separate -iscsi arg to pass various values, instead of accepting
them directly with the -drive argument. Pino is working on fixing
that for 2.7:

Commit 5a7e7a0ba moved mirror_exit to a BH handler but didn't add any
protection against new requests that could sneak in just before the
BH is dispatched. For example (assuming a code base at that commit):

As the framebuffer settings are copied into the result message before it is
reconfigured, inconsistent behavior can happen when, for instance, you set with
a single message the width, height, and depth, and ask at the same time to

The effect of this change is the block layer drained section can work,
for example when mirror job is being completed.

Commit 5a7e7a0ba moved mirror_exit to a BH handler but didn't add any
protection against new requests that could sneak in just before the
BH is dispatched. For example (assuming a code base at that commit):
main_loop_wait # 1
os_host_main_loop_wait
g_main_context_disp
All callers pass "false" keeping the old semantics. The windows
implementation doesn't distinguish the flag yet. On posix, it is passed
down to the underlying aio context.

aio_poll doesn't poll the external nodes so this should never be true,
but aio_ctx_dispatch may get notified by the events from GSource. To
make bdrv_drained_begin effective in main loop, we should check the
is_external flag here too.
Also do the check in aio_pending so aio_dispatch is not called

I tested this series survives the "snapshot + commit" loop reproducer with both
bonnie++ and RHEL installation in the guest.
This supersedes the "virtio: Register host notifier handler as external" patch
from yesterday.
