Just convert the template (use some newer ubuntu version of qemu-img) to qcow2 version 2... They provide qcow2 version 3, you need version 2 for centos....
something like (but please google and confirm): qemu-img convert -f qcow2 /var/lib/libvirt/images/qcow2v3.img -O qcow2 -o compat=0.10 /var/lib/libvirt/images/qcow2v2.img On 26 May 2015 at 05:09, Amin Samir <amin.sa...@opencloud.net.au> wrote: > Hello, > > > > We are using Cloudstack 4.3.2 from shapeblue repo, along with KVM template > dated 2015-01-28, our environment is as follows: > > > > 1) Cloud stack management server Centos 6.6, with Cloudstack 4.3.2 > > 2) Centos 6.6 KVM with the cloudstack-agent installed from shapeblue > repo > > 3) FreeNAS 9.3 for NFS primary & secondary storage. > > 4) Advanced zone > > > > We have configured cloubr0 on eth0 in a single physical network, modified > the labels during the zone launch to match the bridge names on the host. > > > > However System vm cannot launch due the following error in the agent: > > > > uses a qcow2 feature which is not supported by this qemu version: QCOW > version 3 > > > > Anyone please help with this issue, shall we use another system template. > > > > Thanks in advance. > > -- Andrija Panić
