livemigration over specific bridge/nic?
Hi @all, I have a question about the livemigration with libvirt / kvm. I have two bridges configured in my setup of each host. Now I want to set br1 (private network) as default NIC for live migration. Is there any solution to get this work for me? I tried to bind libvirt to those IP-Range but after that the livemigration doesn't works. If you need more details please tell me :)

A race condition introduced by changeset 15175: Re-init hypercall stubs page after HVM save/restore
For an SMP Linux HVM guest with PV drivers inserted, when we do save/restore (or LiveMigration) for the guest, it might panic after it''s restored. The panic point is inside ap_suspend(): .... while (info->do_spin) { cpu_relax(); read_lock(&suspend_lock); HYPERVISOR_yield(); ----> guest might panic on the invocation of this function.

Do systems have to be IDENTICAL for live migration?
I have several systems running 64bit SLES11SP1. I''m trying to Live Migrate between a couple of them and it''s not working, although the same VM will run on each one starting it manually.

Howto set the option script=no for a tap device in the xml file
