[Pkg-libvirt-maintainers] Bug#757644: lxc: Failed to allocate free veth pair

[Rodney Lorrimar]

Package: libvirt-daemon
Version: 1.2.7-6
Severity: important
Tags: patch

Dear Maintainer,

Since last Thursday, when I try to start an lxc domain, it fails with the
following message:

    $ virsh -c lxc:/// start test
    error: Failed to start domain test
    error: internal error: Failed to allocate free veth pair after 10 attempts

If I downgrade the iproute2 package from 3.16.0-1 to 3.15.0-2, I no longer get
this message.

The invocation of "/sbin/ip link add vnet0 type veth peer name vnet1" seems to
be failing with the new version of iproute2.

Cheers,

Rodney
