[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?
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 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 a simple console on the vm.
Here is the machine:
<domain type='kvm' id='2'>
<name>ubuntu</name>
<uuid>8904d893-87dc-dc1f-0219-486745a370f6</uuid>

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 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!

[libvirt-users] How to create a guest os from existing disk image file with virt-install
by Rajiv Rajaian
Hi
I have configured KVM with Fedora Core 13 by enabling the KVM virtualization
option while installing OS.
I have successfully created the guest OS by using the virt-install API
/usr/sbin/virt-install --name centos5 --ram 512 --disk
path=/var/lib/libvirt/images/
centos.img,size=5 --network network:default --accelerate --vnc -c
/tmp/CentOS-5.3-i386-bin-DVD.iso
Os installed successfully and after rebooting am able to login to the guest
OS using the virt-viewer command using vnc viewer ..It shows
Booting from Hard Disk...
GRUB Loading stage2.....
But the guest os is not booted
I want to the create the guest os from existing configured disk
/var/lib/libvirt/images/centos.img.. What modifications should be done with
my configuration file ??
Pleas help me to solve this.
