When I started the installation and reached the point to enter the hostname,
the installation hanged with 'Illegal instruction'. At this point I could not
collect any debug logs. I tried installation with multipath enabled and could
reach a point where I could collect the debug logs. I did not see ''Illegal
instruction' on my console this time but it was recorded in the logs.

== Comment: #9 - INDIRA P. JOGA <indira.pr...@in.ibm.com> - ==
Hi,
I am able to recreate the issue on 2 different host machines with 2
different networks
Raykvm - Travis3En network on host
Yupkvm - Austin network on host.
Tried installing ubunu16.04 using netboot on both kvm hosts and it
failed with same error 'Illegal Instruction"
Regards,
Indira
== Comment: #10 - Richard M. Scheller <rsche...@us.ibm.com> - ==
I was able to get to a shell in the installer so that I could look for broken
binaries that might cause a SIGILL. I found that /usr/bin/wget is incorrectly
linked as a shared object instead of an executable.
I verified from the installer command line that "wget" does, in fact,
die with SIGILL:
/usr/bin # ./wget
Illegal instruction
/usr/bin #
