this bug also affects RHEV-H, based on RHEL 5.5 for RHEV 2.2 To reiterate, the work-around is to run the following as root: brctl setfd <bridge device> 3 This sets the bridge delay down to 3 seconds from the 15 or 30 seconds that are default. This allows bridging while the kvm guest is attempting to pxe boot. That's not a workaround at all. The problem has nothing to do with bridging or network availability in general; the problem is that after *successfully* loading a PXE image, there's no way to instruct the system to boot using the local hard drive. That is, if your PXE configuration looks like this: LABEL local LOCALBOOT 0 It will never work. correct, the PXE configuration is successfully retrieved by the server, but the configuration stated by Lars above does not work, though it should. This configuration is useful because it allows an administrator to reimage a machine by adjusting the pxe boot config applied to a mac address and then rebooting the machine and does not require changing boot order. It looks like the bug https://bugzilla.redhat.com/show_bug.cgi?id=638735 was closed as a duplicate of the bug that this bug is supposed to be a clone of. Contrary to what I though earlier, this bug and #638735 appear to be different issues. this bug is a clone of Bug #472236. 638735 is a dup of 586324. no relation. |
