Probing EDD (edd off to disable) .... ok


Hi all,

I installed Openstack Mitaka on CentOS Linux release 7.3 and getting the following error when I boot an instance. Booting stucks on this.

Probing EDD (edd off to disable) ... ok.

My topology is the following...

Windows 10---VMware---CentOS(VM1)---KVM---CentOS(Mitaka).

Thanks in advance for your help!

I know I'm reviving an old thread, but this is on the first page of DuckDuckGo and other search engines of choice.

I've seen this error on CentOS when the dmesg and systemd messages aren't being printed to the console on Xen and KVM guests. 99% of the time the error is another service hanging, but you can't see it. So the next step is to get verbosity up to diagnose.

Mount the disk on a helper VM, or on the host. Open /etc/grub2/grub.cfg, and remove the following kernel lines:

Code:
rhgb quiet
Then replace console=ttyS0 with the following (note tty0, not ttyS0 for the first occurrence):

Code:
console=tty0 console=ttyS0,115200
Then reboot. You should then see actual service the machine is hanging on.
