virsh sechedinfo with libvirt-0.8.8
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 .

monitiring cpu usage via cgroup
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

libvirt-users Digest, Vol 15, Issue 25
Sorry, let me rephrase the question again: I need define a user /password for sasl but want the authentication at runtime be automatic - no explicit promting the user while accessing a tcp socket with some applications that need authentication (e.g libvirt) I try : saslpasswd2 -c -p -a libvirt <user> and it hangs (if i now press Enter it says : "invalid parameter

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

Re: libvirt issue while deploying a VM
Hi Martin Here is some more info in the libvirt/qemu/instance...log file . Does it help in resolving the issue of : error : qemuMonitorIO:614 : internal>error End of file from monitor In the libvirtd.log file I sent you could see clearly that the debug option is active and this is the most detailed info available (or some better option than log_leve=1 exists ?)

using more than 1 core by a virtual machine
My virtual machine xml file has <vcpu>2</vcpu> clause while the host has 2 physical cpus (cores). Is this enough to cause a VM running 2 endless loop threads to use the 2 cores ? In my case the VM running reports (cat /roc/cpuinfo) that it has 2 vcpus but it uses only 1 core (at a time) because the 'top' at the host shows 100%cpu (out of total 200%) used by the

libvirt issue while deploying a VM
Using libvirt under openstack I encounter a problem when launching a VM with multiple partitions (2 G image) , While a single partition can be launched successfully . The launch is done with Openstack. We are using in libvirtd.conf log_level=1 and log_outputs="1:file:/var/log/libvirt/libvirtd.log" we can see that in /var/log/libvirt/libvirtd.log appear the following error

virt-image issue

I guess it is the output xml file I just used the command with an existing .xml file (thought the utility will modify it according to the specified flags) but got the error message : "ERROR

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

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 (
