qemu+kvm live migration with libvirt

[thebigbigdaddy]

what is qemu?

Worth mentioning: The KVM migration does not transfer the guest disk-image. It only works if both hypervisors has access to the guest disk-image, e.g through an NFS share. The guest disk-image path has to be the same.

The remote VM is paused during the migration while the local vm still runs... When the transfert is completed, the remote VM is resumed and the local VM is stopped...

I'm a little confused.

It seems that during the migration, the vm is paused, memory (State) is copied to the remote system, and the vm is resumed on the destination host.

Is that really a live migration? I thought that live migration should be able to migrate to the remote server without the need to pause the vm?

If so, does KVM support true live migration similar to Xen?

virt-manager is the gui for libvirt, virsh is the shell end. virsh supports new features quicker than the gui as far as I can tell.

Does libvirt have a control panel? or is it simply shell commands?
