This is really strongly recommended against. It is better to mount each controller separately at /sys/fs/cgroup/<controller name> and have /sys/fs/cgrou...

Hello, Stephen, List! Attached is the patch for iproute2 to add the possibility to use fwmark in u32 filters. The kernel part was included in 2.6.10. Please apply! Thank you!

Dear all, I have a thirty-party PCIe card in my host which can work properly in native mode. I wonder if this card can be shared by multiple containers. As far as the network interface is concerned, too many efforts have been made for it. Two dedicated cgroup resource schedulers/subsystem(net_cls, net_prio) have been provided at the kernel level, and libvirt has also done a lot of work on virtual networking to enable network interface sharing between containers. As it's difficult for me to implement all these things that have been done for network interface, I should find other way to...

Hi there, Do you know if there is a way to modify how libvirt interacts with the cgroup? Because, I successfully add the /dev/net/tun support in my LXC container by doing: echo c 10:200 rwm >> /cgroup/libvirt/lxc/instance-00000005/devices.allow But when I restart the instance/LXC container, this option has gone. How can I make this persistant? Is there a configuration file? Thanks
