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

Triaging old bug tickets... can you still reproduce this issue with the
latest version of QEMU? Or could we close this ticket nowadays?

Indeed, with qemu 1.5 we did not observed this issue at all.
Sorry, but I don't have the resources at the moment to do the bisecting.

Sorry, when the table only had the two entries i drew some bad
assumptions from that, and I also missed the fact that hangs were in the
host kernel.
To be clear, running qemu 1.5 on the same host kernel has no issues with
any guest, while qemu 2.0 causes host kernel to hang (indefinately) with
some guests?
Then indeed disregard my comment #5.
Is this 100% reproducible, every time? Would you be able to bisect qemu
to figure out where the problem was introduced?

[Kernel-packages] [Bug 1353947] Re: Hypervisor with QEMU-2.0/libvirtd 1.2.2 stack when launching VM with CirrOS or Ubuntu 12.04
Hello Serge,
I agree that there is probably some missing feature in the guest kernel.
However, I don't believe it is acceptable for the hyper-visor kernel to be
affected from this.
Actually, this is a security issue if a VM user can crash i't Host kernel and
probably some other VMs as well.

Thanks, so the problem appears to be that a feature is missing from the
guest's precise kernel, which was present in the saucy (13.10) kernel.
Could you verify whether using the LTS backport kernel packages in the
precies guest fixes the issue?
