Apparently all is the same in qemu-kvm command lines, comparing c6 with c7 one, but I don't understand who drives instead the QEMU_AUDIO_DRV=XXX in log file that is different between the two guests (none vs spice) and btw also in f24 it is spice: 2016-07-31 23:00:44.778+0000: starting up libvirt version: 1.2.17, package: 13.el7_2.4 (CentOS Build System <http://bugs.centos.org>, 2016-03-31-16:56:26, worker1.bsys.centos.org), qemu version: 2.3.0 (qemu-kvm-ev-2.3.0-31.el7_2.10.1) LC_ALL=C PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin QEMU_AUDIO_DRV=spice /usr/libexec/qe mu-kvm -name f24 ... Could it be that initially c6 was created as optimized for server and then even if changing it to optimized for desktop, it doesn't get actually some parts of the change? Or something related to ich6 drivers in CentOS 6?
