Hi Folks, I'm trying to auto-create a VM using a kickstart server and gPXE with my VMs. The underlying physical host is CentOS 6.0 running libvirt-0.8.1-27, and libvirt-python 0.8.1-27, virt-manager 0.8.4-8. The underlying network config on the physical host is: # ip -o -4 addr show 1: lo inet 127.0.0.1/8 scope host lo 6: vnet0 inet 10.8.31.61/23 brd 10.8.31.255 scope global vnet0 7: vnet1 inet 10.0.4.249/24 brd 10.0.4.255 scope global vnet1 8: virbr0 inet 192.168.122.1/24 brd 192.168.122.255 scope global virbr0 I'm attempting to create the new VM with the following command-line: # /usr/bin/virt-install -n test -r 2048 --vcpus=2 --disk path=/var/lib/libvirt/images/test.img,size=25 --pxe --os-type=linux --os-variant=rhel6 --network bridge=vnet0,mac=52:54:00:07:51:1e --autostart So, I'm trying to create the VM with one NIC, bound to the vnet0 interface on the physical host. The physical host is both the PXE/DHCP server (using cobbler) and the kickstart server. When I run the above virt-install command, while simultaneously running 'tcpdump -i vnet0 -n port 67 or port 68' on the physical host, the VM powers on, boots up, and attempts to PXE boot. However, I never see any traffic on the physical host's vnet0 interface, nor does the DHCP server log any requests. If I boot the VM, then hit Ctrl-B to drop into gPXE's prompt and type autoboot, the first invocation fails, but the second one succeeds. Has anyone seen this kind of behavior ? Is this indicative of a configuration issue on the physical host? An underlying network problem ? Or am I missing an option on my command-line ? I'm a little stumped here, and hoping someone can point me in the right direction. I'm more than happy to RTFM if someone can tell me which M to F'ing R :) -- Thanks Paul
