OVMF in virt-manager?
by Dan Mossor
I realize there may be licensing issues with packaging OVMF directly
with libvirt and virt-manager, but at the very least could the
/domain/os/loader element be exposed in virt-manager or virt-install for
those of us that can utilize OVMF (or other custom firmwares)?
Is there another UEFI option that is being considered/worked on by the
libvirt camp? UEFI is becoming the standard, and it would be nice to
have a native virtualization platform that could provide that emulation.

Change format of backing file?
by Tom Horsley
Just curious here. Say I have a qcow2 image named outer.qcow2
and it has a raw format backing_file named inner.img.
If I do something like
qemu-img convert -f raw -O qcow2 inner.img new-inner.img
rm -f inner.img
mv new-inner.img inner.img
(in other words convert the backing file from raw to
qcow2)
What are the odds that outer.qcow2 will still be usable?
(Like I say - random curiosity here :-).

Ubuntu KVM goes 100% cpu?
by Tom Horsley
I've just tried to install a couple of different ubuntu
variants into KVM virtual machines, (ubuntu 14.04.01
and linux mint 17 xfce).
At some point they always seem to jump to 100% cpu
and hang forever, or sometimes not forever, but when
they come out of the 100% mode, the screen rendering
is hopeless with most of the letters left out of
words.
Does this sound familiar to anyone?
I'm using spice/qxl video and virtio disks. Virt-manager
is running over a somewhat high latency remote connection
with ssh protocol.

Fwd: [Qemu-devel] [ANNOUNCE] QEMU 2.1.0 is now available
by Cole Robinson
In rawhide, fedora 21, and virt-preview now
- Cole
-------- Original Message --------
Hello,
On behalf of the QEMU Team, I'd like to announce the availability of
the QEMU 2.1.0 release. This release contains 2200+ commits from 180
authors.
http://wiki.qemu.org/download/qemu-2.1.0.tar.bz2
The full list of changes are available at:
http://wiki.qemu.org/ChangeLog/2.1
Highlights include:
* Support for memory hotplug on x86 guests
* Support for pinning memory on host NUMA nodes on x86 guests
* Basic hot-plug/hot-unplug support for x86 guests using Q35 machine-type
* Support for TCG-based system emulation on AArch64 (in addition
KVM-based virtualization)
* AArch64 SHA and Crypto instruction support.
* Support for VFIO-based device passthrough on pSeries/PowerKVM guests
* Migration support for virtio-ccw on s390x guests
* Improved IOMMU emulation for SPARC guests
* Full support for USB3 passthrough (including streams).
* Multi-seat support for GTK+ and SDL 2.0 UIs, and lots of bug fixes.
* Dedicated threading model for virtio-blk, virtio-blk dataplane, now supports
almost all features of the block layer including: image formats, POSIX AIO,
I/O throttling, statistics and error recovery
* Fixes migration from QEMU 1.7 when certain bridge/CPU combinations are in
use (see changelog for notes on migration incompatibilities between 2.0
and 2.1 for certain guest configuations), and new code/tools to detect
migration issues
* And lots more...
Thank you to everyone involved!
Sincerely,
Michael Roth
