similar to: C group hierarchy and libvirtd

Hello All, i am trying to set "memory.limit_in_bytes" for all process created by libvirt.But i am not able to achieve this on RHEL systems in Ubuntu servers creating memory cgroup for "libvirt-qemu" user solves the issue.But in case of RHEL system i tried to create a group by editing "cgconfig.conf" and then changing cgrules.conf and restarted cgconfig and

Hello All, From the last couple of days i have been spamming this mailing list with request for configuring Cgroup with libvirtd on Centos systems. I still can not find a permanent solution to limit host RAM to particular value,tried creating a separate hierarchy "mykvm" and changed in sysconfig/libvirtd after that vm's memory cgroup reflects this.But it is

Hi, I'm trying to use cgroups to limit the apache webserver but this doesn't seem to work as far as I can tell. I modified cgconfig.conf like this: group webserver { cpu { cpu.shares="250"; } } and addes this to cgrules.conf: *:httpd * webserver Looking into the "webserver" cgroup shows that the pid's of

Dear list, I am building a Arch server on my Arch box. My tools are QEMU/KVM and libvirt to manage the guest, systemd as system manager. I am looking at implementing the Linux Control Groups facilities for resource management. Even after long hours of reading, I am not quite sure about how to deal with the cgroups facilities. First, do I really need to care about all that, or libvirt and

Dear list, I am bulding a VM using libvirt and lxc for linux container. I have an issue with my cgroups settings: gabx@hortensia ➤➤ ~ # virsh start dahlia error: Failed to start domain dahlia error: internal error: No valid cgroup for machine dahlia My environement: Host : Arch Linux - systemd 208-11, libvirt 1.2.1-4 guest : Arch Linux , machine name : dahlia , /etc/libvirt/lxc/dahlia.xml ,

Hi everyone: I am new here I am using kvm and libvirt on my Dell server. Now i am trying to migrate one virtual machine from a physical server to another. However, I failed everytime. In virsh on physicalServer1, I typed: virsh # migrate virtualmachine1 qemu+ssh://username at physicalServer2/system error: operation failed: migration to 'tcp: physicalServer2:49163' failed: migration

Hi all I have CentOS Linux release 7.0.1406, libvirt 1.2.7 installed. Just after create and start inside LXC container present cgroups. Example for memory: [root@ce7-t1 /]# ls -la /sys/fs/cgroup/memory/ total 0 drwxr-xr-x 2 root root 0 Sep 15 17:14 . drwxr-xr-x 12 root root 280 Sep 15 17:14 .. -rw-r--r-- 1 root root 0 Sep 15 17:14 cgroup.clone_children --w--w--w- 1 root root 0 Sep 15

Is there a way to automatically set the permissions of cgroups directories created by libvirt when a VM is launched? Although it looks like I can set permissions on top-level /cgroup directories via cgconfig.conf, the cgconfig.conf manpage says "Permissions are related only to enclosing control group and are not inherited by subgroups.". From this, I believe that when libvirt

Hello All, We were under the assumption that Cgroups memory controller, limits memory based on just the RSS size of the process. However, i see that the process is getting killed even when the RSS size is very low compared to the limit in bytes. For example: cat memory.stat cache 85880266752 rss 2441216 rss_huge 0 mapped_file 8192 swap 0 pgpgin 29265847812 pgpgout 29244880354 pgfault

hi, I am currently investigating a bug with libvirt lxc. Whenever I do a systemctl daemon-reload on the host, my container loses his memory limit and then reports having access to 8 exabyte of memory. I have tracked the issue down to two parts: memory.limit_in_bytes jumps from the correct value to 9223372036854771712. libvirt lxc appears to set the memory limit in transient way without writing

Hello libvirt users, I'm using the cgroup with QEMU guests. At /etc/libvirt/qemu.conf, I have the following parameter: cgroup_controllers = [ "cpu" ] This controller is successfully mounted and libvirt is able to create subgroups for each VM, it's really great the cgroups support in libvirt. The problem is that I can only set the parameters of a given cgroup under the cpu

Dear Samba gurus, I have a Fedora 8 linux server, running samba 3.0.28a-0.fc8. I am doing the simplest thing of all - exposing a public read-only share within MS Workgroup environment. My server has a fixed local IP address (192.168.1.200) and it's on the same subnet as the rest of the machines. The server and machines are connected to a 24 port CISCO switch. My problem is that I can

I'm trying to permanently change memory allocation for a libvirt-lxc domain. So far I tried changing memory in memory.limit_in_bytes under /cgroup/memory/libvirt/lxc/<container>/.  This didn't help. It appears that libvirt is not reading changes in cgroup. My requirements are 1) Be able to dynamically change memory of a LXC domain without reboot 2) The memory change must survive

Dear R-ers, my task is to simple: to assign cases to desired groupings based on the combined values on 2 variables. I can think of 3 methods of doing it. Method 1 seems to me pretty r-like, but it requires a lot of lines of code - onerous. Method 2 is a loop, so not very good - as it loops through all rows of mydata. Method 3 is a loop but loops through fewer lines, so it seems to me more

Hi, I'm running OpenStack to manage LXC instance through libvirt.
