[Lxc-users] Downgrade disk IO PRIORITY automatically
Hi, I understand that this is not the quite appropriate mailing list to ask the question, but the question is related to the LXC tech we use on the server, so here it goes: Most of the time the LXC containers on our servers work properly, but occasionally someone, somewhere starts an IO heavy operation that kills performance for everybody. For some time I tried to ask people nicely to use ionice -c 3 or run the task offhours but this is not enough. The problem happens quite often for people to complain, but not (IMHO) to warrant purchasing of new hardware. I envision that an ideal solution would be some daemon that would monitor disk IO activity and automatically reduce (or raise, depending how you view it) ionice priority of the process or the container. The daemon would restore the IO niceness after some good behavior period. Is there any solution along the lines? -- Arie -- Cloud Services Checklist: Pricing and Packaging Optimization This white paper is intended to serve as a reference, checklist and point of discussion for anyone considering optimizing the pricing and packaging model of a cloud services business.

Please see http://www.mjmwired.net/kernel/Documentation/cgroups/blkio-controller.txt for details. In my test I found that the blkio controller shipped with older kernel (e.g. rhel6's 2.6.32) doesn't work quite well when the all IO workers in each group are very seeky ones, unless you echo 0 slice_idle to switch to iops mode manually. However in the latest upstream kernel it works very well by the default arguments, without any adjustment.

[Lxc-users] How assign the IP address sequentially?
Hi,
I want to assign the ip address of containers sequentially for eg::
container1 ::195.168.206.1 container2::195.168.206.2 like this.
I have taken out my network cable I think that means DHCP is out of
picture, but when I start the container it gets ipv6 address and not ipv4
address, my conf file contents are ::
CONF FILE::
lxc.utsname = ubuntu
lxc.mount = /home/nishant/ubuntu.fstab
lxc.pts = 1024
lxc.tty = 4
lxc.cgroup.devices.deny = a
# /dev/null and zero
lxc.cgroup.devices.allow = c 1:3 rwm
lxc.cgroup.devices.allow = c 1:5 rwm
# consoles
lxc.cgroup.devices.allow = c 5:1 rwm
lxc.cgroup.devices.allow = c 5:0 rwm
lxc.cgroup.devices.allow = c 4:0 rwm
lxc.cgroup.devices.allow = c 4:1 rwm
# /dev/{,u}random
lxc.cgroup.devices.allow = c 1:9 rwm
lxc.cgroup.devices.allow = c 1:8 rwm
lxc.cgroup.devices.allow = c 136:* rwm
lxc.cgroup.devices.allow = c 5:2 rwm
# rtc
lxc.cgroup.devices.allow = c 254:0 rwm
# ADD THOSE LINES
lxc.network.type = veth
lxc.network.flags = up
lxc.network.link = br0
lxc.network.name = eth0
lxc.network.ipv4 = 192.168.206.1/24
lxc.cgroup.cpuset.cpus=0-1,3
What are changes to be done in order to get the address sequentially?
Please help me ASAP.
Regards,
Nishant
