I use GNOME Boxes 3.12.2 with Windows 7 as the guest OS. When trying to launch the virtual machine I get the following error: > Connection to 'Microsoft Windows 7' failed. If I run Boxes from a terminal in debug mode I get: $ G_MESSAGES_DEBUG=Boxes gnome-boxes (gnome-boxes:20548): Boxes-DEBUG: wizard-source.vala:250: Unable to open qemu+unix:///system: Failed to connect socket to '/var/run/libvirt/libvirt-sock-ro': No such file or directory (gnome-boxes:20548): Boxes-DEBUG: util-app.vala:276: check_module_kvm_loaded: yes (gnome-boxes:20548): Boxes-DEBUG: util-app.vala:256: check_cpu_vt_capability: yes (gnome-boxes:20548): Boxes-DEBUG: libvirt-machine.vala:111: new libvirt machine: win7 (gnome-boxes:20548): Boxes-DEBUG: machine.vala:61: State of 'Microsoft Windows 7' changed to BOXES_MACHINE_MACHINE_STATE_STOPPED (gnome-boxes:20548): Boxes-DEBUG: unattended-installer.vala:662: No media language, using en_US locale (gnome-boxes:20548): Boxes-DEBUG: unattended-installer.vala:662: No media language, using en_US locale (gnome-boxes:20548): Boxes-DEBUG: machine.vala:579: connect display failed: Unable to start domain: Cannot check QEMU binary /usr/bin/qemu-kvm: No such file or directory I don't have /usr/bin/qemu-kvm on my system: $ file /usr/bin/qemu-kvm /usr/bin/qemu-kvm: cannot open `/usr/bin/qemu-kvm' (No such file or directory) This is the list of the binaries that the app-emulation/qemu package provides: $ equery files --filter=cmd app-emulation/qemu * Searching for qemu in app-emulation ... * Contents of app-emulation/qemu-2.0.0-r1: /usr/bin/qemu-i386 /usr/bin/qemu-img /usr/bin/qemu-io /usr/bin/qemu-nbd /usr/bin/qemu-system-i386 /usr/bin/qemu-system-x86_64 /usr/bin/qemu-x86_64 As you can see, there's no /usr/bin/qemu-kvm. This is the elog message I get from emerge when installing qemu: > Migration from qemu-kvm instances and loading qemu-kvm created > save states has been removed starting with the 1.6.2 release > It is recommended that you migrate any VMs that may be running > on qemu-kvm to a host with a newer qemu and regenerate > any saved states with a newer qemu. > qemu-kvm was the primary qemu provider in Gentoo through 1.2.x > The /usr/bin/kvm and /usr/bin/qemu-kvm wrappers are no longer > installed.

If I manually create a symlink from /usr/bin/qemu-kvm to /usr/bin/qemu-system-x86_64 the problem disappears. This happened just after my weekly system update, today. 109 packages have been updated. I previously reported this problem to GNOME developers, but they said it's a problem with Gentoo.

GNOME developer Zeeshan Ali said me to use the "virsh edit" command to change the following line: > <emulator>/usr/bin/qemu-kvm</emulator> into: > <emulator>/usr/bin/qemu-system-x86_64</emulator> Now I can successfully launch the VM without the need for the symlink. But I still wonder if there's some Gentoo problem that need to be fixed for avoiding users to resort to this kind of tricks.
@gnome, is gnome-boxes only compatible with qemu-system-x86_64? In that case, we should patch the value to use that one I think
Well, looks like we should show a warning telling people to fix their VMs with that command instead :/. But that should be probably done by kvm maintainers as will affect to the old VMs
I have the same problem (but I start the VM from a shell script), no qemu-kvm. I have KVM build into the kernel (checked it yesterday while building a new kernel), but no qemu-kvm. I replaced it with qemu-system-i386 and that worked, but it is considerable slower (I also tried qemu-system-x86_64, but that one was even slower than the i386 one).

For the slowness, apparently you have the pass -enable-kvm to the command line. This made it fast again.
grepping in sources I see no hard coded path to qemu-kvm, then, probably the message deserves qemu ebuild itself but I am not sure since I am not familiar with this at all :( @cardoe, @qemu team, what do you think? Thanks a lot
I just ran into the same problem using virt-manager. I am new to kvm/qemu stuff and tried to start a "proof of concept vm" I created a few months ago. After adding the symlink /usr/bin/qemu-kvm -> /usr/bin/qemu-system-x86_64 it worked. Then I tried to use "virsh edit" as the alternative solution suggested, but that required a domain name: error: command 'edit' requires <domain> option Afaik "virsh list" is supposed to tell me my domain name, but in my case the returned list was empty: Id Name State ---------------------------------------------------- So I ended up deleting my vm and creating a new one, since it wasn't important for me. ( Just in case anyone else has the same problem. )
what config file ? the qemu ebuild already warns about qemu-kvm going away, and specifically checks for /etc/libvirt/qemu/*.xml.
