I was curious about containers, so decided to give it a try. Prepared a server as host with a fresh install of CentOS 7, installed lxc and lxc-templates and configured a bridge interface.
I've created a centos container, everything worked fine, except for one strange behaviour: yum installed 7 packages and halted at the 8th one without error, just keeps saying Installing forever. Tried using --verbose and -d9 options, still no error, not even in the yum, dmesg and messages logs
This bug isn't present on debian containers. Does anyone have an idea or has the same issue?
Edit: if I cancel the current yum installation and run yum-complete-transaction the installation finishes without problem. Unless there's a pending count of more than 7 packages to install, in that case I have to cancel the task and run again. Always stops after the 7th package.
