> Hi,
> this could end up in some dummy question...
> ,but we couldn't find any documentation part for this:
> Vanilla ACS 4.6 + (tested with 4.7.x and 4.8 too) doesn't use virtio support as default under KVM.
> Checking the created .xml files on the KVM Hypervisor (Ubuntu 14.04) gave us 'ide' disks and non-virtio network interfaces.
> Creating VMs on the same HV manually by using virt-install, works fine with virtio support.
> Where's the configuration for this on ACS to activate virtio as default?
> Thanks in advance !
