Re: [Xen-devel] [xen-unstable test] 5124: regressions - FAIL

[George Dunlap <George.Dunlap@xxxxxxxxxxxxx>]

Looking at the logs, it looks like both of these failures are probably
due to the intermittent "failure to find the guest's IP address",
which could be because:
* networking is not coming up (bug in Xen system)
* Networking came up but it failed to get an IP address (bug in network system)
* Guest got an IP, but test harness failed to find out what it was
(algorithm for finding IP not robust)

According to this log, in the RH case the guest did receive an IP address:

http://www.chiark.greenend.org.uk/~xensrcts/logs/5124/test-amd64-xcpkern-i386-rhel6hvm-intel/earwig---var-log-xen-qemu-dm-redhat.guest.osstest.log

It doesn't look like stale output from a previous run
(...osstest.log.1 looks like the console output from the install
process), so I think it's reasonable to blame the test harness' IP
detection code.

The XenServer test harness, XenRT, has code to sniff packets and grok
dhcp requests and replies.  Would it make sense to steal that, and see
if it's more robust?
