Public bug reported:
First observed with OpenSolaris 2009.06, and also applies to the latest
OpenIndiana release.

Hardware:
2 x AMD Opteron 6128 8-core processors, 64GB RAM.
These guests boot on equivalent Intel hardware.
To reproduce:

When the qemu-io --nocache option is used the 039 test case cannot abort
QEMU at a point where the image is dirty. Skip the test case.

The dirty bit is cleared after image repair succeeds in qed_open().
Move this into qed_check() so that all callers benefit from this

This is necessary so qemu-img check can call .bdrv_check() and mark the

Hi All,
The following patch set provides a low-overhead system for collecting kernel
tracing data of guests by a host in a virtualization environment.
A guest OS generally shares some devices with other guests or a host, so
reasons of any problems occurring in a guest may be from other guests or

Enable to use splice_write from pipe to virtio-console port.
This steals pages from pipe and directly send it to host.
Note that this may accelerate only the guest to host path.
Changes in v2:
- Use GFP_KERNEL instead of GFP_ATOMIC in syscall context function.

Add a failback memcpy path for unstealable pipe buffer.
If buf->ops->steal() fails, virtio-serial tries to
copy the page contents to an allocated page, instead
of just failing splice().

Use generic steal operation on pipe buffer to allow stealing

This patch adds a user tool, "trace agent" for sending trace data of a guest to
a Host in low overhead. This agent has the following functions:
- splice a page of ring-buffer to read_pipe without memory copying
- splice the page from write_pipe to virtio-console without memory copying
- write tr

This is the v6 of the patchset to support GlusterFS backend from QEMU.
The changes include defining a default value for glusterfs feature
in the configure script and a few minor cleanups suggested by Stefan.
