[ovirt-users] network issue with vm

Hello,

I set up an oVirt cluster and created my first VM. However I can not
seem to get any network connectivity going. The VM is set up to receive
an IP address via DHCP. I can see the DHCP request come in on the
DHCP-server, but subsequently, the offer is lost somewhere. Even when I
configure a fixed IP, I can not ping any host but the VM itself and the
IP in the same VLAN on the hypervisor. My network settings are in the
attachment (output of sudo vdsClient -s localhost getVdsCaps > caps.txt
on the hypervisor). Is there something I should configure on the switch
maybe (it's a Cisco 3560G)?
