Title:
Hypervisor with QEMU-2.0/libvirtd 1.2.2 stack when launching VM with
CirrOS or Ubuntu 12.04
Status in QEMU:
Incomplete
Status in linux package in Ubuntu:
Confirmed
Bug description:
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
