Sven Knohsalla commented on CLOUDSTACK-9302:
--------------------------------------------
Hi [~weizhou]!
we just recently updated to > 4.5.x , ran with 4.4.x before.
So the fix was coming with the latest updates for us.
The VMs were created before!
Thanks for your hints :)
Regards,
Sven.
> Cloudstack not using virtio for KVM instances as default

> Components: Install and Setup, KVM
> Affects Versions: 4.6.0, 4.8.0, 4.7.1

> 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 !
