CLOUDSTACK-9029: Proper support to identify CentOS 7 version number
Signed-off-by: Remi Bergsma <github@remi.nl>
This setting works on CentOS 6 / RHEL 6 but does nothing, as
"cpu" cgroup is not mounted. On CentOS 7 / RHEL 7 systemd does
mount cgroups and "cpu" is co-mounted with "cpuacc". Hence, if
we specify "cpu" then this results in an error because it can
only use them both, or none.
By removing the setting, we rely on the default of qemu, which
is:
cgroup_controllers = ["cpu", "devices", "memory", "blkio", "cpuacct", "net_cls"]
Only if they are really mounted, they will be used. So, this will
work on both version 6 and 7.
The 'fix script' didn't work well, as after a reboot you'd still have qemu
throwing errors. Now we can handle the co-mountedcgroups.
The sequence:
1. add host in UI
2. scp setup_agent.sh to agent host, and execute it. This script receives hostip,zoneid, podid and guid, then runs "cloud-setup-agent" and "cloud-setup-console-proxy". Here, we assume that network/hostname and cloud-agent are already configed and installed.
3. Write a dummy kvm resource into the database, then wait for agent connects to server, by polling the database for every 1 minutes. If it finds the agent is in UP state in database, then return, or wait for at least 10 minutes.
The function stderr was being called with the wrong name of interpolation parameters. The exception was missing from the arguments to the function.
status 5876: resolved fixed
