RHEL/CentOS 7 – Waiting for 1 threads to finish

As with most of my posts recently I have been looking at what is required to setup an isolated lab environment and from what started out as a simple idea, has slightly snowballed, due to one or more issues along the way.

The most recent is… During the installation I found that after selecting my installation options via the GUI, I was confronted with a status message “Waiting for 1 threads to finish”.  It sat there for a very long time!

The fix

Adding the “inst.geoloc=0” kernel parameter.  So my CentOS 7.2 code block in the pxelinux.cfg/default now looks like this;

LABEL Install_CentOS_7_2
    MENU LABEL CentOS 7.2
    KERNEL centos7/vmlinuz
    APPEND initrd=http://rhc-server.lab.tobyheywood.com/centos7/images/pxeboot/initrd.img inst.repo=http://rhc-server.lab.tobyheywood.com/centos7 inst.geoloc=0

Why does this make a difference

Well, it turns out the RHEL/CentOS 7 installation process & Fedoras’ for that matter try to be clever and determine your geographical location.  Now in a sandboxed world, that is going to be pretty challenging for the installer to accomplish, so it sits there, doing for all intents and purposes not a lot.

Adding the above mentioned parameter helps by simply disabling that functionality.

As with all things in life reading the manual is very useful. 🙂

  1. Thanks for this trick, it was causing me some bother, but I still get this error when installing a CentOS VM using “inst.geoloc=0 inst.cmdline”
    Although it happens much less frequently I’m still finding the issue

    1. Hi Martyn,

      If you’d like to share the full set of installation options you are passing to the installer I will see if I can replicate the issue in my lab.
