I did some tests on ovirt-3.6-snapshot and mixing local and shared
storage domains is working (with a tweak).
If you opted for Shared storage type when you created a new Data Center,
you can mix NFS/FC/iSCSI shared storage domains with POSIX Compliant FS
data domain using a local storage device (logical drive or partition,
formatted with ext4/xfs).
Only catch was, I had to chown the device node to vsdm:kvm for it to be
utilized by oVirt (eg. chown 36:36 /dev/sda2).
It doesn't work on 3.5.4 though, I've changed ownership for the device
node, had to change ownership for the ext4 fs itself residing on the
partition, and it still refused to connect stating that not all ovirt
nodes can write to it (that was expected).
I hope this helps,

Can somebody confirm that this will be the case? Or is there

No, you can not mix local and shared storage.
For shared storage, the basic assumption is that all hosts see all the
storage, so you can migrate vms from any host to any host.
You can use local storage by exposing it as shared storage, for
example, serve local lvs or files as luns via targetcli.
