[Qemu-devel] How to management KVM virtual machines via libvirt?

Hi all,

   I am trying to management the VMs created by KVM commandline. However, I
found the libvirt cannot connect to the VMs or manage it from virsh. Can
anybody provide any help?
   Best,

Yi

  Shouldn't this go to libvirt mailing list?

There is a way to tell libvirt to attach to an externally
launched KVM process, provided you have configured it with
a monitor socket using the UNIX protocol. This is not always
entirely successful though, due to the sheer number of
different ways QEMU can be launched, which libvirt does not
always understand:

In the long run, I'd really recommend just launch the guests
via libvirt in the first place
