OVMF in virt-manager?
by Dan Mossor 15 Aug '14

15 Aug '14

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 13 Aug '14

13 Aug '14

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 08 Aug '14

08 Aug '14

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.

05 Aug '14

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
