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 . 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

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 ?)
Thx

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

virt-image issue
Hi
Does anybody work with the virt-image utility.
- I do not see where/how one specifies the pre-defned image or the CD
iso image to produce the image from
- what is the .xml file requested for ? 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 :

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

How can I add ''schedinfo'' to the domU configuration?

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

virDomainSetSchedulerParameters() does not support KVM?
Hi,
I have one RHEL 5.5 Xen box and one RHEL 5.5 KVM box. In the Xen box, the

But in KVM box, it can not work:

Is it because that the libvirt
