Description of problem:
Similar problem to what we hit with ipxe, which also doesn't (didn't) obey option 26. The installation starts but then times out fetching the kickstart because the inbound packets dropped, due to having a TCP MSS greater than the MTU of the virtual network (1400 in our case).
Version-Release number of selected component (if applicable):
unreleased develop 608161a (24.0 candidate)
Steps to Reproduce:
1. configure OpenStack integration on your account
2. run a RHEL4 recipe
Beaker creates an OpenStack instance and runs the RHEL4 installer on there. But it will hit EWD with Anaconda prompting for a language (that means it didn't fetch the kickstart).
RHEL4 dhcp client does not request option 26 nor honour it when sent. MTU always defaults to 1500. Can't change RHEL4 now so we will just need to exclude it from OpenStack.
This was actually included with Beaker 24.0.
