To enable common msix support to be used with pass through devices,
don't attempt to change the BAR if the device already has an
MSI-X capability. This also means we want to pay closer attention
to the size when we map the msix table page, as it isn't necessarily
covering the entire end of the BAR
I've been porting the qemu vfio driver to use the common msix
infrastructure and hit a couple issues. The first patch addresses
the problem that a device may already have MSI-X capability setup
and non-adjustable BARs, so msix_init should be able to use the
existing capability instead of adding it

OVERVIEW:
Virtproxy proxies and multiplexes socket streams over a data channel between a
host and a guest (currently network connections, emulated serial, or
virtio-serial channels are supported). This allows for services such as guest
data collection agents, host/guest file transfer, and event
Process control packets coming in over the channel. This entails setting
up/tearing down connections to local services initiated from the other
end of the channel.

Right now if we pass through multiple USB devices with matching vendor

second device is already attached. The only way to get those devices
working is to specify bus.addr which is inconvenient if devices are

This patch adds code to look up data cluster offsets in the image via
the L1/L2 tables. The L2 tables are writethrough cached in memory for
performance (each read/write requires a lookup so it is essential to
cache the tables).
With cluster lookup code in place it is possible to implement
bdrv_is
This patch introduces the qed on-disk layout and implements image
creation. Later patches add read/write and other functionality.

This patch implements the read/write state machine. Operations are
fully asynchronous and multiple operations may be active at any time.
Allocating writes lock tables to ensure metadata updates do not
interfere with each other. If two allocating writes need to update the
same L2 table they will

This patch adds support for the qemu-img check command. It also
introduces a dirty bit in the qed header to mark modified images as
needing a check. This bit is cleared when the image file is closed
cleanly.
If an image file is opened and it has the dirty bit set, a consistency

QEMU Enhanced Disk format is a disk image format that forgoes features
found in qcow2 in favor of better levels of performance and data
integrity. Due to its simpler on-disk layout, it is possible to safely
perform metadata updates more efficiently.

That would be perfect, I think. I mean, if we could stick only to check
to do all our unit-testing
Well, the current "make test" is more integration test
Anthony,
The following patches have been sent to the list and look good to me. I've
also tested them.
The changes (since d03703c81a202cea156811e5dbc8e88627c19986) are available
in the following repository:

The werror option now affects not only write requests, but also flush requests.
Previously, it was not possible to stop a VM on a failed flush.
