Domain Editing
Your domain is virtual hardware. This hardware is described in an XML file. The XML file is stored in /etc/libvirt/qemu/. There is one file for each domain. It is possible to use virsh to dump the XML.
virsh dumpxml clone
In a physical computer it is not a good idea to replace hardware while the computer is running. The same can be said for the virtual domain. Start by shutting down the guest, then edit the domain. That being said there are many pieces of virtual hardware that can be added while the guest is running.
virsh edit clone
Console
During installation it is usefull to have access to the console of the domain. After the installation this is no longer needed. The following section can be removed from the configuration to disable access to the domain console.
<graphics type='spice' autoport='yes' listen='192.168.1.33'> <listen type='address' address='192.168.1.33'/> <image compression='off'/> </graphics>
Memory
Increase or decrease the memory by editing this line.
<memory unit='KiB'>1048576</memory> <currentMemory unit='KiB'>1048576</currentMemory>
Disk
This is how we add an additional 16G harddisk to a domain, while the domain is running..
Create the new volume.
lvcreate --size 16G --name kvm_clone_vdb vg2
Add the disk to the domain.
virsh attach-disk clone --source /dev/vg2/kvm_clone_vdb --target vdb
