[Qemu-devel] [ANNOUNCE] QEMU 1.5.0-rc3 is now available

[Anthony Liguori]

Hi,

On behalf of the QEMU Team, I'd like to announce the availability of the
fourth release candidate for the QEMU 1.5 release.  This release is meant
for testing purposes and should not be used in a production environment.

http://wiki.qemu.org/download/qemu-1.5.0-rc3.tar.bz2

You can help improve the quality of the QEMU 1.5 release by testing this
release and reporting bugs on Launchpad:

https://bugs.launchpad.net/qemu/

The release plan for the 1.5 release is available at:

http://wiki.qemu.org/Planning/1.5

Please add entries to the ChangeLog for the 1.5 release below:

http://wiki.qemu.org/ChangeLog/Next

The following changes have been made since v1.5.0-rc2:

 - Revert "migration: don't account sleep time for calculating bandwidth" (Michael Roth)
 - main-loop: partial revert of 5e3bc73 (Stefan Hajnoczi)
 - main-loop: narrow win32 pollfds_fill() event bitmasks (Stefan Hajnoczi)
 - virtio: add virtio_bus_get_dev_path. (KONRAD Frederic)
 - qga: unlink just created guest-file if fchmod() or fdopen() fails on it (Laszlo Ersek)
 - qga: distinguish binary modes in "guest_file_open_modes" map (Laszlo Ersek)

Regards,

Anthony Liguori

When I  test with  the latest Debian 7.0 armhf [1], I got
'Segmentation fault' error.
But qemu-1.4.1-win64.7z [2] is good.
