Hi techs, Could you please explain or refer me to documentation where I could find a description of global_quota schedinfo option. Someone told me that it could mean a cpu limitation in percents like: global_quota : 25000 (does it mean cpu limit % set to 25 ?) Is it true? What other parameters mean in below output? I didn't find any related documentation at libvirt.org. Could you help me

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 trying to get Samba and CFS (cryptographic file system) to work. What I want is to mount a crypted directory (on my Debian Sarge server) as a Samba share to my WinXP box. I've already set up a crypted directory (/crypt/crypt) as a user. And I've also set up a Samba share for this 'virtual' directory. I can access and delete files from that folder over the Samba

I''m switching all my fulltext searching over to ferret using the acts_as_ferret plugin on windows (for development, will be deployed on linux). In my tests I have a setup method as follows to ensure the index is reset for each test: def setup Item.rebuild_index end This works fine for the initial few tests but then suddenly fails for the last few tests when it seems to be

Hi All,    I am running into an issue mounting a Samba share from our Linux server. We are running Samba 4.8.8 on CentOS  7.6.1810. I have done a some testing, and I can't get the root cause of the error. Testing: CentOS 7.6 client -> Samba server, mounting fails - mount.cfs mount error(13): Permission denied CentOS 7.6 client -> Win10 desktop share, mounting works Fedora 29

Hi, Is there some tool or method in centos that can limit cpu usage to some percentage for specified processes that consume large cpu resource? I found cpulimit which is only able to limit one process. what I want is one tool that can limit several same processes' cpu usage. Thanks! Regards andrew

Hi all: I have an Ubuntu 18.04 system. What is the easiest way to run all of my virtual machines with a low priority? Say a "nice" level of 15. I just do not want my virtual machines to have too much of an impact in any other processes on the system. Thanks in advance, rdiez

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

Is it possible to set the CPU frequency exposed to the guest operating system for a kvm-enabled virtual machine ? The documentation does not mention anything about it. Thanks.

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?

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
