I'm running oVirt 3.5 newly installed with one test VM. I have the engine running on separate HW with eth0 being the management interface I have 2 compute nodes with eth0 being the management interface and eth1 having a vlan trunk with all of the VM networks If I install a guest from the CD image it all works fine and picks up an IP from the DHCP server. However if I switch the boot order to PXE first the gPXE DHCP request times out. Using tcpdump I can see the DHCP discovery packets get as far out as the physical trunk interfact eth1 (i.e. it gets past all of the virtual interfaces) but any other machines in that same VLAN don't see the DHCP request and neither does the DHCP server. My network settings are: Name: TestCluster External Provider: NO Network label: TC Enable VLAN tagging: 306 VM network: YES MTU: Default 1500 Under 'Setup Host Networks' Boot Protocol: DHCP Any ideas? -- [Any errors in spelling, tact or fact are transmission errors] - (Stolen from) Dag Wieers Edson Manners Systems Administrator, Research Computing Center FSU Information Technology Services Dirac Science Library., Room 150B Tallahassee, Florida 32303-4120
