Fedora-Cloud-Atomic-Vagrant-23 20151119.x86_64.vagrant-libvirt.box

I have reproduced same error on my local computer with

sudo python3 -m unittest tunirtests.cloudtests -v
sudo systemctl stop crond.service
sudo systemctl disable crond.service
sudo reboot

I failed to ssh back to system after rebooting.

Hey aalam,

I think I know the problem here. I believe we have a problem because the network device is not coming up as eth0 on atomic hosts. It actually comes up often with a random name.. so on a subsequent reboot you could get ens2,ens3 etc.. Which means you'll get a different IP from dhcp, which means vagrant loses track of your ip and you can no longer get in to the host.

We have /etc/udev/rules.d/80-net-setup-link.rules symlinked to /dev/null though so it's not clear why this is happening.

-bash-4.3# ls -l /etc/udev/rules.d/80-net-setup-link.rules
lrwxrwxrwx. 1 root root 9 Oct 30 02:06 /etc/udev/rules.d/80-net-setup-link.rules -> /dev/null

This page explains that having that symlink in place should be sufficient http://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames/ . I guess for now we could add the other disabler which is to have net.ifnames=0 on the kernel command line.

thanks. That explains that why got different IP every-time after reboot.
