Collecting system stats
Hi,
I am trying to create a report across all my KVM hypervisors using libvirt
API and I need some assistance in figuring out the right API calls. My
report will contain the total available memory, CPU, disk across all
hypervisors, versus the amount used by the virtual machines. This report
will help figure out if we are running low on hypervisor disk, CPU or
memory and if we need to add more.

Listing on Host sFlow under Applications>Monitoring
Would it be possible to list the Host sFlow project in the Monitoring
section of http://libvirt.org/apps.html?
Host sFlow <http://host-sflow.sourceforge.net/>
Host sFlow is a light weight agent running on KVM hypervisors that
links to libvirt library and exports standardized cpu, memory, network
and disk metrics for all virtual machines using sFlow protocol.
Thanks,
Peter

How are you measuring CPU usage?
Hello,
Recently I''ve received some complaints that there is excessive but
intermittent latency of network traffic to domUs on some of my
servers.
Upon investigation it seems that on some servers, indeed traffic is
occasionally delayed by up to 140ms where something like 5ms RTT
would be expected. The average RTT is not unusual; since this is
only occasional packets it only affects the

Getting CPU and memory usage statistics for the host
Hi,
I have noticed that virt-manager has the ability to show me the current cpu- and
memory-usage of both the host and running guest machines.
How does it do that?
I could make good use of that information myself in the client applications I'm
writing, however, from what I can see on
http://libvirt.org/html/libvirt-libvirt.html, I have no idea how to go about
getting it from libvirt. In

Decent How-To now on the wiki for setting up Transport Layer Security
Hi all,
For anyone that's interested in setting up TLS with libvirt, but hasn't
gotten around to it yet, there's a decent guide on the wiki now:
http://wiki.libvirt.org/page/TLSSetup
It's user focused (ie SysAdmin's), and has lots of pics explaining
concepts, plus shows what needs to be done, and shows how to do it.
Please note, it doesn't cover SASL, it's just

XCP bandwidth management
Hi all,
I''ve got XCP 1.0 up and running nicely and would like to use it in
production. However I''m struggling with the concept of bandwidth management.
It seems like such a common problem that everyone must have, but I can''t
find any clear direction in which to go.
The dedicated host I am using (Hetzner) gives me a 5TB monthly bandwidth
quota which needs to be shared

sco 5.0.5 not booting on hard disk
Hello,
I am trying to run SCO unix 5.0.5 with KVM.
I have created the Virtual Machine with virt-manager.
The installation runs correctly, but when the virtual machine reboots
from hard disk, i obtain this message :
"FATAL: No bootable device."
If i run manually the virtual machine without the suboption "boot=on" in
the "-drive" option, the virtual machine boots

Source RPM please
Hi,
I''m a long ext3 user (rpmfind.net). I propagated ext3 on some of our
server box (W3C webservers are ext3 based too now).
I might be tempted of testing out your kernel RPMs but unavailability
or the source RPM and the SMP version are definite showstoppers. Please
provide them. In the meantime I will stick to my own set of kernel ext3
RPMs at ftp://rpmfind.net/pub/veillard/ext3/

Checkpointing
Hi,
Is there any way you can save a xen domain without suspending it or stopping
it? I want to set up something so if my xen session crashes I can fire up
another xen session from the save file that I created 5 minutes before the
crash and hopefully minimize downtime.
Thanks

Re: Collecting system stats
If you need to continuously track libvirt metrics, you might want to
install Host sFlow agents on each of your KVM hypervisors:
http://host-sflow.sourceforge.net/
The Host sFlow agent is a lightweight daemon that links to the libvirt
library on the hypervisor and sends hypervisor and VM metrics using the
sFlow protocol to a central collector. You could use an sFlow analyzer like

Mounting an lvm
I converted a system disk from a virtualbox
VM and added to the config on a qemu VM.
All seems well until I try to mount it. The
virtual machine shows data for the disk
image using commands like:
pvs
lvs
lvdisplay xena-1
but there is no /dev/xena-1/root to be
mounted. I also cannot seem to figure out
whether the lvm related modules are available
for the virtual machine kernel.

grep
Good Morning. Below I like statement like

with the \\b option which I read long time ago which Ive found useful.
Are there more or these options, other than ? grep? Thanks.

Back porting of ext3 to 2.2.X line
I've not seen this asked since I've been on the list; but was wondering...
I'm currently sticking to the 2.2 line and have no plans to move to 2.4
right now. Is there any attempt to back port some of the changes in the
newer 2.4 line back into 2.2? ext-0.0.7a.tar.gz has been stable thus
far, but it's getting kind of old.

List volumes of a domain
Hi all,
I'm using libvirt java binding (libvirt-java-0.4.6)
I'd like to know if the Domain class offers an API to query volumes
attached to a particular domain or should I parse the XML domain

remote lxc via libvirt?
Has support for creating or using lxc containers on remote machines
been added to libvirt yet?
https://help.ubuntu.com/12.04/serverguide/lxc.html says
"Libvirt is a powerful hypervisor management solution with which you
can administer Qemu, Xen and LXC virtual machines, both locally and
remote."
so I assume it's been done and I'm just having trouble seeing it...

Virtual switches support (Openvswitch, VDE,...)
Hi,
IIR/UC there have been a couple of discussions lately about possible
evolution of libvirt's network management features to eventually support
more kinds of virtual networking technologies like Openvswitch, VDE,...
Could a kind and informed soul keep us on touch with progress in the field ?
Thank you very much in advance
PS: I wish this will be available before/for 1.0 release...
