Hi Jaco, thanks for the feedback!
> * CentOS 7 by default comes with firewalld - something that's not covered under official docco's. I initially thought it was iptables preventing access from LAN, but managed to find this issue via accessing services through SSH tunnel There's a small warning banner in the documentation page you mentioned: http://docs.opennebula.org/4.8/design_and_installation/quick_starts/qs_centos7_kvm.html > Warning > Some commands may fail depending on your iptables/firewalld configuration. Disable the firewalls entirely for testing just to rule it out. You have probably missed it, there might be a few too many notices ;) > * Telling people to 'disable SELinux' is simply a bad idea & sets a bad precedent & encourages lax security practices IMHO. It's there for a reason. For now I've set it to be permissive rather than disabled, but will re-enforce it again later. Right, I completely agree. It'd be great if someone could contribute the SElinux policies for OpenNebula so we can add them to the packages. It shouldn't be that hard, but unfortunately it's something we haven't had time to do yet. > btw. found the bug in the Ubuntu docco: Absolutely! thanks for pointing it out. I've fixed it. > Otherwise I've followed the guide dutifully, but I'm unable to provision my 1st instance. In the logs I can see it's trying to find: /var/tmp/one/vnm/tin/pre. Where does that 'tin' come from? Supported vnm's are: 802.1Q dummy ebtables fw ovswitch vmware.
