I don't see the running guest in virsh

  • 772

Using CentOS 5 with KVM.

I have downloaded this KVM applicance, and when unzipped it is just a .img file. No xml file supplied.

I can start the guest with

 /usr/libexec/qemu-kvm -hda /data/kvm/slash.img -m 512

and it works.

Now I would like to make a config file for the guest.

The problem is when I do

# virsh -c qemu:///system list
 Id Name                 State
----------------------------------

#

I don't see the guest as expected.

Does anyone know what is wrong?

linux kvm-virtualization centos5

  1. Best Answer

    You can get an example of .xml file here:
    http://libvirt.org/drvqemu.html#xmlconfig

    You modify it according to your needs.
    Here you can all formats about xml format:
    http://libvirt.org/format.html

    About seeing all the virtual machines, try with 

    virsh list --all

    So you can see all the installed virtual machines and not only those running.

  2. You need to tell virsh about your KDE image.This is accomplished by either importing an existing XML file that's customized according to your needs or generating one

    Method 1. Create and customize the XML: get a copy from somewhere else or download the one specified in the previous answer, and place it in in a temporary place. My case /home/user/centos.xml (my case centos.img, yours IMAGENAME.img); qcow or qcow2 will work as well

    Import (create) it into virsh

    virsh create /home/user/centos.xml

    Once imported in libvirt with virsh in can be found in /etc/libvirsh/qemu/

    Method 2. Generate a new XML by "installing" the existing image

    virt-install --connect qemu:///system --name centos --ram 256 --disk path=/var/lib/libvirt/images/base-centos.img --bridge=virbr0 --vnc --vncport=5901 --accelerate --os-type=linux --cdrom /dev/cdrom

    where path= location of your image

    stop force the previous command

    virsh destroy centos

    Look for cenots in virsh

    virsh list --all

     Id Name                 State
----------------------------------
  - centos               shut off

    Start the new VM

    [root@ libvirt]# virsh start centos
Domain centos started

[root@ libvirt]# virsh list 
 Id Name                 State
----------------------------------
  1 centos               running
