Public bug reported: I am running Ubuntu 15.04 (not 15.10/dev). Due to another bug in qemu 2.2 I decided to try the 2.3.1 packages (from build here). I realise there is potential dependency issues and the config is likely untested.
However as this could be a genuin issue, I wanted to report that With these installed, along with latest libvirt I noticed that whilst the bug I needed a fix to was addressed (a savevm issue), any VM configured to use "spice" would not launch. libvirt (via virt-manager) reports "Error starting domain: unsupported configuration: spice graphics are not supported with this QEMU" which is also reflected in syslog: Jul 8 11:50:36 jonesn-ThinkPad-W530 libvirtd[2142]: unsupported configuration: spice graphics are not supported with this QEMU On reviewing the build logs, it appears qemu HAS been built with spice ie it reports: spice support yes (0.12.7/0.12.5) As some additional validation I also then replaced these packages with another private ppa (a second opinion) - in no means official of course. https://launchpad.net/~jacob/+archive/ubuntu/virtualisation . These packages, which also include virt-manager also result in the same error It's possible that spice support is being incorrectly validated Relevant extracts of my VM definition include <emulator>/usr/bin/kvm-spice</emulator> <channel type='spicevmc'> <target type='virtio' name='com.redhat.spice.0'/> <address type='virtio-serial' controller='0' bus='0' port='1'/> </channel> <graphics type='spice' autoport='yes'/> <video> <model type='qxl' ram='65536' vram='65536' vgamem='16384' heads='1'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/> </video> ** Affects: qemu-kvm (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1472571 Title: libvirt reporting spice not supported in 2.3.1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu-kvm/+bug/1472571/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
