Can you login into your vms via vnc and investigate, i.e. if ssh daemon is running and if ssh keys are correctly inserted into your login-user's authorized_keys?
The ping problem may be a routing problem on your host. Check if the host has ip_forwarding enabled such that the host forwards packages between "eth0" and "br0", that is between the bridge and your host's physical nic. If this does not help, investigate your routing tables and try to track your ping's package flow with tcpdump.
