Monitor your Fedora disk usage:
abrt-cli [list|rm] journald --disk-usage [sudo] yum clean all
Store vm|docker data outside /var
virsh pool-edit default
#/etc/sysconfig/docker OPTIONS="-g /data/docker"
Enable virsh for `wheel` users (from goldmann.pl)
sudo tee -a /etc/polkit-1/rules.d/80-libvirt.rules << EOF # Don't ask password if user is in the wheel group. polkit.addRule(function(action, subject) { if (action.id == "org.libvirt.unix.manage" && subject.local && subject.active && subject.isInGroup("wheel")) { return polkit.Result.YES; } }); EOF # Set context. chcon --reference=/etc/polkit-1/rules.d /etc/polkit-1/rules.d/80-libvirt.rules
To set a list of unmanaged-devices you can just do the following.
cat >> /etc/NetworkManager/NetworkManager.conf <<EOF [keyfile] unmanaged-devices=interface-name:vboxnet0;interface-name:virbr0;interface-name:docker0 EOF
and
sudo nmcli connection reload
Strangely I had to put this in NetworkManager.conf. Using
/etc/NetworkManager/conf.d/20-unmanaged-bridges.conf didn’t work.
When you dockerize your jboss, the expose directive (luckily) doesn’t open firewall ports.
On Fedora20 you need to update your firewalld configuration:
1- add one or more services to /etc/firewalld/zones/public.xml
2- define ports in /etc/firewalld/services/eap6-standalone.xml <service> <short>eap-standalone</short> <port port="8080" protocol="tcp" /> ... </service> Now # restorecon -R /etc/firewalld/ Then #firewall-cmd --reload
Babel sponsored a Fedora DS release for Sabayon/Gentoo. The work has been done by the Sabayon maintainer lxnay with my support: we involved richm aka Mr. Fedora DS.
This work lead us to discover some issues on the server:
1. the AdminServer – using mod_cgi – plays the dup2/close game to close stdfd: this caused an error on Sabayon but not on Fedora.
