Re: [ovirt-users] network issue with vm
Hi Tiemen, have you checked for general network setup issues? Sorry, can only guess here. To check oVirt I suggest to create another VM with a DHCP server. Example: I recently had quite the same problem - it turned out the DHCP server used the wrong gateway. Vlans where configured routed in the switch; thus the DHCP requests reached the server while the offers were not send back via the same gateway.

[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)?
