Hello all

Today I've tested https://github.com/openstack/tripleo-quickstart/ on a fresh CentOS 7.2 (hosted server, 32 GB RAM)

These are well-known problems that I've found on CentOS forums, not precisely new, but I thought you may all be interested in knowing that these block the installation of tripleo-quickstart at certain points (first at the undercloud VM creation, second at the initial steps of overcloud deploy)

Maybe you want to add a comment in the documentation?
  1. #ERROR: qemu-kvm: -chardev pty,id=charserial0: Failed to create chardev\n
    1. I solved it via https://loginroot.com/qemu-kvm-chardev-ptyidcharserial0-failed-to-create-chardev/
    2. Basically, replace the devpts line of /etc/fstab with “devpts /dev/pts devpts gid=5,mode=620 0 0“
    3. Then do “mount -o remount /dev/pts“
  2. #ERROR: Node 141e60b7-19ea-43d1-b14e-fe07193cdf7d did not pass power credentials validation: SSH connection cannot be established: Failed to establish SSH connection to host 192.168.23.1 ; and DEBUG ironic.common.utils [req-8d62ae59-8832-4eec-82d6-c9139d7624a8 – – – – -] SSH connect failed: Incompatible ssh server (no acceptable macs) ssh_connect /usr/lib/python2.7/site
    1. I solved it via http://stackoverflow.com/questions/28399335/python-paramiko-incompatible-ssh-server
    2. Just edit /etc/ssh/sshd_conf and add another MAC algorithm: MACs hmac-sha1
    3. Then, restart the service with systemctl restart sshd
I was also very annoyed by the lack of "virsh list --all" as root - as documented here https://github.com/openstack/tripleo-quickstart/blob/master/docs/accessing-libvirt.md. It should be also commented beforehand, IMO :)

Other than those two problems, the installation went very smoothly. It took much more space than I expected (like 31GB in /home space in the $VIRTHOST).


Good job guys :)


PS: I wrote the end-to-end installation on my personal blog https://simplenfv.wordpress.com/2016/05/16/deploying-openstack-on-just-one-hosted-server/
