Re: [ovirt-users] oVirt / ROM images / PXE

Once upon a time, Paul Heinlein <heinlein(a)madboa.com&gt; said: One DC, one cluster, version 3.5. Intel Nehalem CPU. I've PXE booted CentOS 5, 6, and 7 VMs (64 bit for all and 32 bit for 5/6). I'd suspect something in the network setup. I have VLANs on an 802.1q trunk on an LACP bond (with oVirt bridging the VLANs to VMs). My DHCP server (separate physical CentOS 6 box) is also running VLANs on 802.1q on LACP bond, with dnsmasq listening on one VLAN. I'd look at traffic coming out of the VM on the node, and coming into the DHCP server, and see who sees what (are the requests coming out of the VM, is the DHCP server seeing them, is it replying, does the VM get the reply). If the DHCP requests are making it to the server, the next thing to see is if there is any difference in the DHCP options requested between the different ROM images (maybe your DHCP config isn't matching up correctly in some case that works on mine?). -- Chris Adams <cma(a)cmadams.net&gt;
