Subject [jira] [Reopened] (CLOUDSTACK-7524) cloudstack-setup-agent should check and raise exception if cgroups are properly configured
Date Thu, 30 Apr 2015 18:46:06 GMT

Marcus Sorensen reopened CLOUDSTACK-7524:
-----------------------------------------

In my testing, it seems that it might be less intrusive and easier to just not add the cgroup
setting in /etc/libvirt/qemu.conf during agent install (delete the line from the python setup
scripts). The cgroups get applied anyway on EL7 by libvirt/systemd-machined when supplied
in the xml, so no need to explicitly request it of qemu.conf. We've spent so much time monkeying
with the cgroups and configuration management that it might be a bit intrusive to try to remount
things manually via this script.

> on RHEL7, cgroups cpu,cpuacct are co-mounted. Libvirt will fail to start Vms in such
case. Before adding LXC host, cloudstack-setup-agent script should check cgroups and raise
exception if they are co-mounted
