Hey everyone, Can anyone explain the scedinfo parameters? I am wondering if I can use this, (along with host side niceness scheduler tweaks) to cause vCPUs to dominate the total time of the CPUs they are pinned to. Here are the sched info parameters: Scheduler : posix cpu_shares : 0 vcpu_period : 0 vcpu_quota : 0 emulator_period: 0 emulator_quota : 0 The documentation (

Hi, I'm running into some problems with libvirt and hoping someone can point me at some instructions or maybe even help me out. First, are there any requirements on qemu version in order to use the "numatune" and/or "cpu/numa/cell" elements? Or do they use cgroups and not the native qemu numa support? Second, are there any instructions on how to set up cgroups? I

Hi I tried to restrict usage of some running VM by cpu.shares (i.e. set to 10 from original 1024) on loaded system and it seem doesn't work as I expected... all running processes has same CPU usage (by htop) :-/ Does anyone has same experience?

Hi , I was previously using xen and currently moved to KVM. I am using libvirt to manage these VMs. In den's credit scheduler , I had the ability to set a cap on the cpu usage for a VM. But I was not able to find a similar substitute in KVM. I find that we can use cgroups to provide shares for VM but that will be more like weight based and it doesn't set a hard cap for that VM. I tried

Hello, I'm running Debian Sid with libvirt/qemu/kvm packages from experimental: $ qemu --version QEMU emulator version 0.13.0 (Debian 0.13.0+dfsg-2), Copyright (c) 2003-2008 Fabrice Bellard $ kvm --version QEMU emulator version 0.13.0 (qemu-kvm-0.13.0 Debian 0.13.0+dfsg-2), Copyright (c) 2003-2008 Fabrice Bellard $ libvirtd --version libvirtd (libvirt) 0.8.6 /etc/libvirt/qemu.conf

Hi, Seems this question is not related with libvirt directly, but I still want to ping this list to see if someone can be help. The OS in my desktop box is Ubuntu 12.10, the kernel is 3.5.1. I installed the cgroup utility package with:#apt-get install cgroup-bin, but after I installed these packages successfully, I can't find cpu_quota/cpu_period controller in the /sys/fs/cgroup/cpu folder.

Hi I was asking about the fedora 14 kernel if it is good enough for cgroup usage because I am trying to set a cgroup under cpu subsytem ( /dev/cgroup/cpu/group1/ ) that have /cpu.rt_runtime_us of 100000 while cpu.rt_period_us has a value of 1000000 i.e a ratio of 1/10 . still when I run a task (endless loop) in that group (cgexec -g cpu,cpuset:group1 ./test) it gets all the cpu core time

Hi, I'm using libvirt/kvm with openstack. When vm has CPU stall, the instance can't be destroyed. I have asked the question on openstack user mailing list and received no answers in weeks. Here is one example: # virsh destroy instance-00000085 error: Failed to destroy domain instance-00000085 error: Failed to terminate process 61222 with SIGKILL: Device or resource busy

libvirt schedinfo : ------------------ What is the meaning of the 'cap' parameter in the schedinfo virsh command (what are the units and range of values ) and what is the 'weigth' parameter ? Zvi Dubitzky Email:dubi at il.ibm.com

Hi, How can I add ''schedinfo'' to the domU configuration? These parameters are default after reboot. -- Regards, Piotr Jasiukajtis | estibi | SCA OS0072 http://estseg.blogspot.com

I have fedora14 installed with standard libvirt-0.8.3. I can start VM using .xml files and also run: virsh schedinfo. the cgroup CPU controller is mounted and active . In fact I have the path to the Virtual machine : /dev/cgroup/cpu/libvirt/qemu/<vm name > Now I upgraded to libvirt-0.8.8 from a tar ball ( configure , make , make install) . I rebooted , new libvirtd started . virsh
