similar to: Question about blkiotune.device_weight

Hi all, I want to limit the I/O bandwidth inside the container, so I used virsh command blkiotune. But when I enter a command: virsh # blkiotune lxcguest --weight 250 I get following errors: error: Unable to change blkio parameters error: Requested operation is not valid: blkio cgroup isn't mounted I also have blkio cgroup mounted. What can be the problem? Thanks in advance. Regards,

Hi experts, When I test lxc-enter-namespace interface, it turned out such an error: hzguanqiang@debian:~$ vir version Compiled against library: libvirt 1.1.4 Using library: libvirt 1.1.4 Using API: LXC 1.1.4 Running hypervisor: LXC 3.9.6 hzguanqiang@debian:~$ vir list Id Name State ---------------------------------------------------- 1544 instance-00000015

Hi experts, When I test lxc container with lxc-enter-namespace command, It reported an error as following: root@debian:~/github/libvirt# vir lxc-enter-namespace lxc --noseclabel /bin/df -hl error: Cannot get namespaces for 3145: Function not implemented It seems that setns is not supported by my kernel. But from the following info, It seemed the reason is just libvirt/autoconf doesn't

Hi Gao feng, I noticed one of your patch which adds cpuset cgroup support for lxc have been merged in libvirt 1.0.4. But I can't find any virsh command to set cpusettune for lxc container. Is there anyone? And how can I configure cpusettune for lxc container lively? Thanks ------------------ Best regards! GuanQiang

Hi Gaofeng, It seems that I've got the answer. In manual page about setns, it said that library support was added to glibc in version 2.14 while my libc version is 2.13. Thanks for help anyway.

Hello! We are using oVirt in our infrastructure, which uses libvirt as backend. Last time we needed to activate storage QoS aka libvirt blkiotune parameters. So some questions appeared about how libvirt limitation mechanism works: 1. What happened to overlimit storage traffic in small time period after we apply blkiotune parameters on high loaded virtual machine on fly: a) All over-limit

Hi, Daniel. It seems that the virsh command 'lxc-enter-namespace' encapsulates several functions just as 'virDomainLxcOpenNamespace', 'virDomainGetSecurityLabel', 'virDomainLxcEnterSecurityLabel' , 'virDomainLxcEnterNamespace', 'virFork', etc. And I found only 'virDomainLxcOpenNamespace' is provided by python package 'libvirtmod_lxc

Hi Guys, When I created a lxc container by libvirt, I logged into the lxc container and noticed that info under /proc/ dir did not match the lxc container resource. Is the /proc dir in lxc container just showing the same thing as the lxc host? If I want to monitor the realtime resource usage inside the lxc container, What should I do? -------------- Best regards! GuanQiang 2013-07-23

Hi, is there a way to configure blkio via libvirt (xml)? Regards Erkan -- ?ber den grenzen mu? die freiheit wohl wolkenlos sein

Hi Daniel, I noticed that the patch "Add support for hotplug/unplug of disk devices in LXC" you wrote had been merged into libvirt of version 1.0.2. But when I used this function, it report an error with details as following: ubuntu@lxc:~$ vir attach-device instance-0000002c disk.xml --config error: Failed to attach device from disk.xml error: Unable to create device
