You just want 'virsh capabilities' to show the binary you care about.

Re: [libvirt-users] Connecting libvirt to manually compiled QEMU
Still no success virsh capabilities doesn't return any "emulator" output. When I check the "libvirtd.log" there is an error: 2014-03-20 11:25:00.056+0000: 1014: error : virCommandWait:2188 : internal error Child process (LC_ALL=C PATH=/usr/local/sbin:/usr/ local/bin:/usr/bin:/usr/sbin:/sbin:/bin /usr/local/bin/qemu-system-x86_64 -help) status unexpected: exit status 1 I have searched mailing lists for this error ( https://lists.fedoraproject.org/pipermail/virt/2012-July/003358.html) but the solution suggested involves KVM which I cannot do (I just want to run simple qemu 1.4.0 ) libvirt version: 0.98 qemu: 1.4.0 On 19 March 2014 18:06, Daniel P.

Re: [libvirt-users] Connecting libvirt to manually compiled QEMU
Fixed Thanks for all the help. It's simple just configured & installed QEMU 1.4.0 through standard way and restarted the libvirt-bin service through initctl. Libvirt runs *"qemu-system-x86_64 -help*" command to get the emulator version (virsh version). This option was disabled in my custom QEMU, so just had to enable it.
