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

virsh shutdown
Hi
For some reason recent libvirt code (0.8.3 and even before) the 'virsh
shutdown <domain> ' is not effective .
It issues an ok message but the domians remains in a runnning state .
Only th e destroy works fine.
Any idea ?
thanks

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

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

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

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 :

Sorry, let me rephrase the question again:

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

libvirt schedinfo :

What is the meaning of the 'cap' parameter in the schedinfo virsh
command (what are the units and range of values ) and what is
the 'weigth' parameter ?

IR canonicalization: shufflevector or vector trunc?
We use InstCombiner::ShouldChangeType() to prevent transforms to illegal
integer types, but I'm not sure how that would apply to vector types.
Ie, let's say v256 is a legal type in your example. DataLayout doesn't
appear to specify what configurations of a 256-bit vector are legal, so I
don't think we can currently use that to say v2i128 should be treated
differently than v16i16.

IR canonicalization: shufflevector or vector trunc?
Right - I think that case looks like this for little endian:
define <2 x i32> @zextshuffle(<2 x i16> %x) {
%zext_shuffle = shufflevector <2 x i16> %x, <2 x i16> zeroinitializer, <4
x i32> <i32 0, i32 2, i32 1, i32 2>
%bc = bitcast <4 x i16> %zext_shuffle to <2 x i32>
ret <2 x i32> %bc
}
define <2 x i32> @zextvec(<2 x i16>
