We are currently investigating the failure. One of our suspects is that on kvm autotest, each new qemu process instance might have a new NIC mac address, and that might be triggering some condition in qemu in conjunction to the guest init scripts.
It is important to note that this problem does not affect qemu-kvm.git, or RHEL based branches for that matter. -- You received this bug notification because you are a member of qemu- devel-ml, which
