[libvirt-users] Updates to cucmber-vhost - guineapigs wanted! :)
by Matthew Macdonald-Wallace
Hi all,
For those of you that are using cucumber for Continuous Integration or
similar I've created a set of steps that enable you to use cobbler and
cucumber to auto-provision using Libvirt.
I've just made some changes to the code however I don't have access to
all the hardware/software required to test it fully.
If you are able to, please check out the code from
http://tinyurl.com/virtcuke (my github repo) and test, posting bugs
against the project.
Thanks in advance,
Matt

[libvirt-users] virDomainSetSchedulerParameters() does not support KVM?
by Zhang Qian
Hi,
I have one RHEL 5.5 Xen box and one RHEL 5.5 KVM box. In the Xen box, the
following command works well:
$ virsh schedinfo RHELu3T
Scheduler : credit
weight : 256
cap : 0
But in KVM box, it can not work:
$ virsh schedinfo RHEL5u3
Scheduler : Unknown
error: this function is not supported by the hypervisor:
virDomainGetSchedulerType
Is it because that the libvirt APIs virDomainGetSchedulerParameters() and
virDomainSetSchedulerParameters() does not support KVM?
…
[View More]Is there any plan for libvirt to support that? Or any equivalent in libvirt
can be used to do the same thing for KVM？
Thanks!

[libvirt-users] Too many active clients?
by jeremy avnet
Hello,
I'm receiving a lot of these since a couple of days ago:
libvirtd: 16:30:10.960: error : qemudDispatchServer:1282 : Too many active
clients (20), dropping connection
I'm trying to figure out where all these active clients are coming from. I
have a daemon running the interacts with libvirtd, but it only creates two
long-lived connections (I'm very sure). What constitutes an active
connection?
The only other libvirtd access that goes on are some quick lived munin
process which connect …
[View More]in various ways and using virsh on the command line.
Libvirt version 0.7.5-5ubuntu27 on Ubuntu 10.04.
Thanks!

[libvirt-users] Hello world help needed
by Dale Amon
I am trying to work my way up the learning curve through
a forest of conflicting and mostly non-working examples
and help pages spread about the internet.
I have had no trouble getting a basic vm to build
and to then start it up. But I have utterly failed
to gain access to the machine.
The only host I have available that can run it is a
remote server. I have not got the networking side
working yet, but I can live with that for the moment
because I have thus far not been able to get access
to …
[View More]a simple console on the vm.
Here is the machine:

I dumped the original and added the pty stuff from an example, but
when I create it and connect to the console:
# virsh -c qemu:///system create ubuntu2.xml --console
Domain ubuntu created from ubuntu2.xml
Connected to domain ubuntu
Escape character is ^]
nothing appears and nothing I type echoes.
At least I can escape though...
I seem to have no trouble creating them, but it sure would
be nice to be able to access them.
Oh, and btw. Every time I create a VM with the ubuntu
ubuntu-vm-builder kvm hardy --mem 256 --iso /path/to/ubuntu-8.10-server-i386.iso
ubuntu-vm-builder kvm lucid --mem 256 --iso ubuntu-10.04-server-amd64.iso
It leaves a loopback disk behind that never goes away. I've
had to reboot the server once already and upped loop_max to 32
so I would be able to work longer before doing so again.

[libvirt-users] libvir: Domain error <domName>: invalid argument in virDomainGetXMLDesc
by Priya
All,
I just downloaded and installed libvirt-bin and this is my first email
to the group, so I apologize in advance if my questions are too naive!
So, I am trying to access VMs running on xen3.2 hypervisor (host with
kernel 2.6.24-24-xen) using virt-manager installed on a machine
running Ubuntu 9.04 (client machine). I got to the point where I can
connect to my virtual machine and my domain-0 through the virt-manager
client (meaning that I already have libvirt, ssh-askpass downloaded
and the …
[View More]libvirtd and xend running on my host machine), and on the
client machine I can view the window showing the statistics of CPU
utilization of my domain-0 and user domain. The attachment shows a
shapshot of the virt-manager on my client machine.
Now when I try to access the GUI of either of domain-0 or the user
domain (by selecting the specific domain and clicking open) I get the
following error message in a pop-up on my client and in the libvirtd
console on the host:
"libvir: Domain error xen_2: invalid argument in virDomainGetXMLDesc"
I tried to Google this error, but I don't find any clear answers. It
seems to be a bug in the libvirt implementation that has been detected
and resolved already. And I am confused as to why is it that such a
recent version is still buggy? Should I have downloded another version
instead? I desperately wish to resolve this problem and would
appreciate any guidance.
Many thanks!
