This patchset provides QEMU with an implementation of the Sun CG3 8-bit
framebuffer. It is based upon Bob Breuer's original work which has been
rebased onto git master, and is now capable of running with an OpenBIOS CG3
FCode ROM instead of requiring copies of proprietary Sun ROMs.
The motivation
The CG3 framebuffer is a simple 8-bit framebuffer for use with operating
systems such as early Solaris that do not have drivers for TCX.

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) qemu-i
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

If you want a pull request to not be applied you need to follow
up to the 00/nn cover letter for the pull request to say so.
Otherwise I am likely to either miss the request or no
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
to work with op blockers.

This applies cases on drive-backup on blockdev-backup, except cases with

Also add a case to check source == target.

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.

The QEMU process stays running if the test case fails. This patch fixes
the leak by installing a SIGABRT signal handler which invokes
qtest_end().

overhead. x2apic emulati

If you specify the same option more than once (e.g. -o cluster_size=4k
-o lazy_refcounts=on), qemu-img silently ignores all but the last one. This
series fixes it to either consider all options or to give an error message.
Boolean option can still be given more than once as they aren't problematic
Multiple -o options has the same meaning as having a single option with
all settings in the order of their respective -o options.

If you specified multiple -o options for qemu-img create, it would
silently ignore all but the last one. Similarly, for other options the
last occurence wins (which is at least a bit less surprising). Error out
instead.
