What global_quota option mean? What's its logic?
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

cgroups limitations on Virtual machines
I have 2 VMs launched by : 'virsh create <xml file>' . Both VMs get 2 vcpus (out of total 2 cores of the host) I then try bias their cpu cycle quota by manipulating the cpu_shares ( virsh schedinfo --set cpu_shares=<value> vm1/2 ) so that VM1 will get 3 times the cpu cycles VM2 gets. (e.g : VM1 cpu_shares = 150 . VM2 cpu_shares = 50) . There are no other VMs defined or

quick question on schedinfo
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 (

questions around using numatune/numa/schedinfo
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

Diskless Centos & Cgroup config changes
Hi, I have OS 'image' that boots via PXE and mounts over NFS. (7.5.1804). I am wanting to explore allowing cgroup usage on this configuration. The root image is exported read-only over NFS and am using statetab & rwtab to allow some persistent parts of the filesystem as well as read/write where needed. I have tried setting /sys in the statetab and this causes the machine to fail,

cgroup for VM - does it work properly?
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?

SSH console for qemu
Hello, I'm using qemu with libvirt and I want to create SSH emergency console to linux/unix guests, same way as it is realized in qemu VNC. Maybe someone could help me to determine a place to dive in this question. I think the best way to make it - extend qemu API. But if this could be made with libvirt - this will be also fine. -- Nikita A Menkovich http://libc6.org/ JID: menkovich at
