Hi
So, then you have solved you restore issue? The permission issue is usually
because a misconfigured qemu.conf (dynamic_ownership [1]) or a problem
accessing the datastore from the hosts (mount points, mismatch ID of
oneadmin...)
Regarding the network problem you have to create bridge1 in the hosts and
bind it to the target physical Host for the dummy configuration. However if
you are using other modes like 802.1Q then the bridge is created for you.
This depends on how the host was defined. Information about networking
modes and configuration is here[2]
Cheers
Ruben
