libvirt users - Jun 2014 - Re: ERROR: Domain not found: no domain with matching name 'ubuntu'

Hi guys,

I am new to QEMU-KVM, libvmi and libvirt stuff.
Libvmi uses libvirt.
I am trying to to run process-list example of libvmi and getting error as
below. It seems that this error may be due to libvirt as it is not able to
find domain.
I seek your kind help on below error:

spanhal1@seclab2:~/KVMModule/libvmi-0.10.1$ sudo ./examples/process-list
ubuntu
libvir: QEMU error : Domain not found: no domain with matching name
'ubuntu'
VMI_ERROR: Failed to get domain id from name.
Failed to init LibVMI library.1

Here are few details of step I performed:
1. I have installed KVM module. (version 3.5)
2. Installed QEMU-KVM. (version 1.2.0)
3. Installed libvirt(version 0.1.2.5)
4. Installed libvirt-bin(version 0.9.8-2ubuntu17.19)
5. Installed libvmi. (version 0.10.1)
6. Then I am trying to run process-list example and I am getting error as
above.
   sudo ./examples/process-list ubuntu


To deal with this, I tried creating VM with domain name ubuntu using steps
given at below link.

https://help.ubuntu.com/community/KVM/CreateGuests
http://virt-tools.org/learning/install-with-command-line/

Create VM:

$sudo apt-get install virtinst

$sudo fallocate -l 8192M /var/lib/libvirt/images/guest.img

$sudo qemu-img create -f qcow2 /var/lib/libvirt/images/guest.qcow2 8192

spanhal1@seclab2:~/KVMModule$ sudo virt-install --connect qemu:///system -n
ubuntu -r 512 -f guest.qcow2 -s 12 -c
/home/spanhal1/KVMModule/ubuntu-12.04.4-desktop-amd64.iso --vnc
--noautoconsole --os-type linux --accelerate --network=network:default
ERROR    Host does not support any virtualization options

Here are few workaround and information for this error:

1. spanhal1@seclab2:~/KVMModule$ modprobe kvm
   spanhal1@seclab2:~/KVMModule$ lsmod | grep kvm

   kvm_intel             137888  0
   kvm                   422160  1 kvm_intel

2. spanhal1@seclab2:~/KVMModule$ kvm-ok
   INFO: /dev/kvm exists
   KVM acceleration can be used

Check if virutalization is enabled by BIOS:
   spanhal1@seclab2:/var/log/libvirt$ sudo modprobe msr
   spanhal1@seclab2:/var/log/libvirt$ sudo rdmsr 0x3a
   5
   (Values 3 and 5 mean it's activated).

First, you should find out why the "qemu-system-x86_64 -help" command
returns status 1 and fix that. Run that command manually and you might
get a clue.

I tried running qemu-system-x86_64 -help" command manually. But it seems
that it work normally. Here is the output. Kindly guide me.

Libvirt doesn't directly use LibVMI, but I don't recognize that as
something that qemu uses either.  You'll need to investigate what this
library is, who is trying to use it, and why it isn't initializing.  If
the error is from qemu, libvirt is just passing the message through.
