Resizing the xbzrle cache during migration causes qemu-crash,
because the main-thread and migration-thread modify the xbzrle
cache size concurrently without lock-protection.

This series adds for point-in-time snapshot NBD exporting based on
blockdev-backup (variant of drive-backup with existing device as target).
We get a thin point-in-time snapshot by COW mechanism of drive-backup, and
export it through built in NBD server. The steps are as below:
1. (SHELL)
This drops BlockDriverState.in_use with op_blockers:
- Call bdrv_op_block_all in place of bdrv_set_in_use(bs, 1).
- Call bdrv_op_unblock_all in place of bdrv_set_in_use(bs, 0).
- Check bdrv_op_is_blocked() in place of bdrv_in_use(bs).
The specific types are used, e.g. in place of
BlockDriverState.op_blockers is an array of lists with BLOCK_OP_TYPE_MAX
elements. Each list is a list of blockers of an operation type
(BlockOpType), that marks this BDS as currently blocked for a certain
type of operation with reason errors stored in the list. The rule of
usage is:
* BDS user
This adds the enum of all the operations that can be taken on a block
device.

It makes no sense to check for any blocker on bs, we are here only
because of the mechanical conversion from in_use to op_blockers. Remove
it now, and let the callers check specific operation types. Backup and
mirror already have it, add checker to stream and commit.

Dropping intermediate could be useful both for commit and stream, and
BDS refcnt plus bdrv_swap could do most of the job nicely. It also needs

This tests the workflow of creating a lightweight point-in-time snapshot
with blockdev-backup command and export it with built-in NBD server.
It's tested that after the snapshot it created, writing to the original
device doesn't change data that can be read from target with NBD.
Signed-off-by:
Similar to drive-backup, but this command uses a device id as target
instead of creating/opening an image file.
Also add blocker on target bs, since the target is also a named device
now.
Add check and report error for bs == target which became possible but is
an illegal case with introduction
Now it's safe to allow reference for backing_hd in the interface.

Drive backup is a read only operation on source bs. We want to allow

Hello,
I've been tring to use QEMU-1.5.0 and Libvirt-1.1.0 to run a VM with a nbd
network disk, the VM is created by Libvirt as follow(Please attention to the
red words):

This makes use of op_blocker and blocks all the operations except for
commit target, on each BlockDriverState-backing_hd.
The asserts for op_blocker in bdrv_swap are removed because with this
change, the target of block commit has at least the backing blocker of
its child, so the assertion is not
Hi Community,
I am new to qemu, I am trying to familiarize myself with aarch64
timer/interrupt support (maybe someone already did this, but not merged
into mainline yet).
As shown in include/qemu/timer.h, there are 6 categories of APIs:
- QEMUClockType
- QEMUTimerList
- QEMUTimerListGroup
-
When path is truncated by PATH_MAX limitation, it causes QEMU to access
incorrect file. So use original full path instead of PATH_MAX within
9pfs (need check/process ENOMEM for related memory allocation).
Also find/fix several another related issues when failure occurs.
- check 'fh' in
During the test, I found that if the path is long, the performance is
very very slow under 9pfs (whether apply this patch or not, the results
are the same).
So after this patch passes checking, I will/should analyse this
performance issue, next.
Thanks.
