Hi All, I am new to libvirt, i wander how we can achieve below objective, i read through a lot fromlibvirt.org <http://libvirt.org> but couldn'tfound any thing solid somethingequivalent to this:-

virsh dumpxml dom> /tmp/dom.xml $EDITOR /tmp/dom.xml&& virsh define /tmp/dom.xml

What i try to achieve is to have one management server that install with libvirt in place then we can use libvirt to connect to other libvirt box to provision the vm-create, vm-delete& capable to vm-modified the CPU,MEM,HDD,boot sequence, vnc password attached& detech network card..on the targeted VM.

there are commands to do the modifications? e.g. for vnc password changes, HDD: # virsh update-device for mem: # virsh setmem # virsh setmaxmem for detach/attach NIC: # virsh attach-device # virsh detach-device Not sure how you want to modify the "CPU", you could see if following commands satisfy you requirement: # virsh setvcpus (if you are using qemu-kvm, the cpus in guest won't be hotpluged/unhotpluged actually, as it lacks support) # virsh vcpupin All these commands support change persistent config, But if you are trying to modify a bunch of domains, scripts is better, though it's not supported offically by libvirt to modify the domain configs externally.
