+Hypervisor with QEMU-2.0/libvirtd 1.2.2 stack when launching VM with CirrOS or Ubuntu 12.04
+
+The issue observed when running an hypervisor with QEMU 2.0/libvirtd 1.2.2
+The VM network interface is attached to a PCI virtual function (SR-IOV).
+
+When we ran VM with guest OS CirrOS or Ubuntu 12.04 we observed an hipervisor hang shortly after the VM is loaded
+We observed the same issue with Mellanox NIC and with Intel NIC
+
+We’ve tried few combinations of {GuestOS}X{Hypervisor} and we got the following findings:
+When a hypervisor is running QEMU 1.5/libvirtd 1.1.1 - no issue observed
+When a hypervisor is running QEMU 2.0/libvirtd 1.2.2 - CirrOS and Ubuntu 12.04 guest OSes caused hypervisor hang
+When a hypervisor is running QEMU 2.0/libvirtd 1.2.2 - CentOS 6.4 and Ubuntu 13.10 - no issue observed
+
+The problematic guest OSes are with kernel versions ~3.2.y
