I was going to post a new thread about Centos 7 but thought I might piggy
back on this one since it is a similar topic. I have xCAT 2.8.3 currently
and it sounds like from the thread here that upgrading to 2.10 is part of
the solution for deploying Centos 7.1. Currently the issue I'm having is
that during a PXE boot it fetches the correct centos 7.1 image and begins
trying to deploy but after it shows "Mounted Configuration File System" and
"Started Show Plymouth Boot Screen" I get a message like this:
"dracut-initqueue: Warning: Could not boot" and hangs there.
This isn't a very explicit error, as to what caused it, and I didn't learn
much from removing "quiet" from the PXE kernel boot parameters. I also
can't get the ctrl+alt+F keys to work, at least in a VM, for showing
different terminals like you could in Centos 6 (which was very helpful for
debugging).
Is this most likely because the kickstart file itself is not formatted
correctly (I'm reusing my Centos 6.4 kickstart - until I figure out how
Centos 7.1 differs), or perhaps that the kickstart is not being properly
fetched from the gpxe configuration in /tftpboot/xcat/xnba/nodes? Currently
the gpxe boot configuration for the node I'm trying to deploy Centos7.1 to
looks like this:
#!gpxe
#install centos7.1-x86_64-compute
imgfetch -n kernel http://
${next-server}/tftpboot/xcat/osimage/centos7.1-x86_64-install-compute/vmlinuz
imgload kernel
imgargs kernel repo=http://10.20.0.101:80/install/centos7.1/x86_64 ks=
http://10.20.0.101:80/install/autoinst/node0067c ksdevice=bootif cmdline
console=tty0 console=ttyS0,115200n8r BOOTIF=01-${netX/machyp}
imgfetch http://
${next-server}/tftpboot/xcat/osimage/centos7.1-x86_64-install-compute/initrd.img
imgexec kernel
I manually changed ksdevice to "bootif" just to make sure it was using the
right interface (it was set to eth0 but Centos 7.1 got rid of "eth" for
"em" didn't it?). Nonetheless, I think my kickstart is being sucessfully
fetched, because I changed the disk formatting commands in the kickstart
and when I removed "quiet" from the boot I saw errors related to disk
formatting/partitioning. So I'm partial to thinking that the old Centos 6.4
kickstart configuration is not 100% compatible with Centos 7.1, but I want
to double check to see what xCAT 2.10 bring to the table that might be
necessary for Centos 7.1 deployment. Comments or thoughts?

Josh
