I suggest you rebase your patch set to the current git head, fix for example src/libvirt_public.syms since we are past 0.8.8, and drop any mention of cgroup in the comments or documentation since that API is generic and doesn't need to be tied to that specific implentation used for QEmu, for example if there is something equivalent to tune Block I/Os in VMWare it's very unlikely to be based on cgroups :-) thanks !

[libvirt] [PATCH 0/6] new virsh command blkiotune support
Hi All, This series implements a new command blkiotune for virsh. A lot of code borrows from memtune. You are able to tune blkio cgroup tunables by this command as follows. Show tunables #virsh blkiotune My_guest weight : 900 Tune tunables(Set IO weight) #virsh blkiotune My_guest --weight 500 #virsh blkiotune My_guest weight : 500 Thanks, Gui -- libvir-list mailing list libvir-list@redhat.com https://www.redhat.com/mailman/listinfo/libvir-list
