Re: [libvirt-users] virsh modified option... alternative..
? 2011?10?21? 17:32, vmnode guy ??:
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.
