QEMU error : Domain not found: no domain with matching name 'ubuntu' while running process list example

[shp.panha...@gmail.com]

Hi guys,

I am new to QEMU-KVM and libvmi stuff. I seek your kind help on below error when I am trying to run process-list example:

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 libvmi. (version 0.10.1)
4. Installed libvirt-bin and libvirt. (version 0.9.8)
5. Created a virtual machine as follows:
    $ qemu-img create -f qcow2 vdisk.img 15G
    $ sudo qemu-system-x86_64 -hda vdisk.img -cdrom ubuntu-12.04-desktop-amd64.iso -boot -d 1024 -vnc :1
6. Then I am trying to run process-list example and I am getting error as above.

Intel(R) Core(TM) i3-3240 CPU @ 3.40GHz

Here is the output after I created and run the VM using command:
sudo qemu-system-x86_64 -hda vdisk1G.img -boot c -m 1024 -vnc :1        ..create a VM
sudo vncviewer :1

spanhal1@seclab2:~$ lsmod | grep kvm

kvm                   422160  1 kvm_intel

Libvirt log file entires:

What is the output of

# virsh list --all ?

[shp.panha...@gmail.com]

I have started VM using command:

sudo qemu-system-x86_64 -hda vdisk1G.img -boot c -m 1024 -vnc :1        ..create a VM

sudo vncviewer :1                                                                                  .. view VM

and then run the virsh list --all command.

Here is the output command:

spanhal1@seclab2:~/KVMModule$ sudo virsh list --all
 Id Name                 State

Looks like your VM is crashing?  Anything useful in the qemu logs?

Hmmm… i don't know about the way you create VM… it looks suspicious.

For example, you try using process-list with a vm named 'ubuntu', however, there is no info whatsoever in your commands (to create your vm) that explicitly shows you give name 'ubuntu' to your vm.

so my suggestion:

could you try this

    $ virsh -c qemu:///system list --all

if that command can shows vm named ubuntu, then solve your problem using environment variable LIBVIRT_DEFAULT_URI=qemu:///system

if that command still shows nothing, then please try read this 'https://help.ubuntu.com/community/KVM/CreateGuests'

@Ady:

Here I gave my try...

spanhal1@seclab2:~/KVMModule/libvmi-0.10.1$ sudo virsh -c qemu:///system list --all
 Id Name                 State
----------------------------------

Also, I have already tried by using environment variable LIBVIRT_DEFAULT_URI=qemu:///system.

@ Bryan: I will update the QEMU logs soon.

Thanks,

Sanket

[Ady Wahyudi Paundu]

Then most likely there is no VM named 'ubuntu' in your system.

You can try one of several ways to create VM from this KVM documentation: https://help.ubuntu.com/community/KVM/CreateGuests

@Bryan: I am not able locate QEMU logs. Could you please help me to locate it.

@Ady:

Hi, I tired creating VM 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        ..package to run virt-install command

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:

spanhal1@seclab2:~/KVMModule$ modprobe kvm

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

kvm_intel             137888  0
kvm                   422160  1 kvm_intel

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

It will depend on how Qemu is being installed.  But usually it is something like /var/log/qemu.

@brayan:

Hi,

I am not able locate QEMU logs at path given by you.

I have installed QEMU using following steps.

Install QEMU

======================

Step 1:

Download QEMU-KVM source code

http://sourceforge.net/projects/kvm/files/qemu-kvm/

Step 2:

Install QEMU

$ tar -xvf qemu-kvm-1.2.0.tar.gz

$ cd qemu-kvm-1.2.0

$ ./configure --enable-debug --target-list="x86_64-softmmu"

$ make

$ sudo make install

Kindly help me locate QEMU logs.

Thanks,
Sanket

[Bryan D. Payne]

This sounds like a good question for the qemu mailing list.

[shp.panha...@gmail.com]

Ok. Thanks for information :)

[alex kp]

anyone know how to fix the issue ?

I always hate dangling questions like this; so to answer the question simply;  libvirtd needs to be reloaded.

# systemctl reload libvirtd

or for the cool people;

# /etc/init.d/libvirtd reload

Cheers.
