[Qemu-devel] [ANNOUNCE] QEMU 1.0-rc1

[Qemu-devel] [ANNOUNCE] QEMU 1.0-rc1

[Anthony Liguori]

Hi,

On behalf of the QEMU Team, I'd like to announce the availability of QEMU 1.0, 
release candidate 1.  This is the first release candidate for the 1.0 release. 
This is not intended for production use but rather for testing.

To participate in the testing effort, please read the Testing Wiki[1] and sign 
up to test a subsystem.  Any problems should be reported on Launchpad[2] or 
qemu-devel.

If you've contributed to the 1.0 release, please take a moment and update the 
Changelog[3] so we can have a high quality change log for the release.

The full release schedule[4] is also available on the wiki.

http://wiki.qemu.org/download/qemu-1.0-rc1.tar.gz

Known Issues:

1) There is an issue resetting Linux guests that is still being investigated. 
Shutting down QEMU completely and restarting works around the issue.

Thanks.

Are there supporting windows binaries (ie, various virtio drivers and 
vdagent)?

Also, I've seen instructions to build the various windows binaries from source 
in a number of different places.  Is there an "official" site describing the 
method?

Thanks,
-Rick

Hi Rick,

there is a page on QEMU's wiki: http://wiki.qemu.org/Hosts/W32.
Please tell me if there is information missing there (or add it yourself
to the wiki).

If anybody has more information on supporting w32 binaries,
this can be added to the wiki, too.

Cheers,
Stefan

Sorry for the confussion.  I run Qemu on a Linux host, with WXP as a guest.  
I'd like to give 1.0 rc a run, but first I'd like to make sure I have the 
correct windows virtio drivers, and correct windows vdagent.  There is no 
documentation that I can find that specifies what, where or how regarding those 
windows guest components.

Thanks,
-Rick

vdagent is for Spice.  The Spice windows driver is not based on virtio and 
should be available from spice-space.org.

Windows virtio drivers are available in binary form from Fedora Hosted.  See 
http://alt.fedoraproject.org/pub/alt/virtio-win/latest/images/

Note that the Windows virtio driver binaries aren't signed.

FWIW, WinXP drivers from the latest .iso there can't be installed
(it fails during driver install phase, saying "No driver for this
hardware found at given location"), while previous version works
just fine, and the driver itself appears to be fine too (one can
replace previously installed driver binary while windows isn't
watching and it continues to work).  I added a note to the KVM
wiki page about this, at
http://www.linux-kvm.org/page/WindowsGuestDrivers/Download_Drivers

Thanks,

I can't confirm this - the drivers work for me both in Qemu and in
qemu-kvm. Note however that the organisation on the ISO is weird - the
virtio-net driver is in \XP\x86, while the rest of the drivers are in
\WXp\x86.

These drivers works if you upgrade from previous version.  But on
clean install of winXP - at least virtio-blk (and maybe virtionet
too, I don't remember) - can't be installed.  There were several
reports about this problem on IRC too, and the solution has been
to use previous version of the drivers (where the directories are
ok).  I mean the drivers from .iso, and installing them _after_
the system has been installed already (install to IDE first, and
add virtio drive as second drive).

I installed fresh winXP just a few days ago and also hit this problem.
