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?
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.
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
