Dear maintainer,
On my bi-processor board (Allwinner A20 CPU), with a Debian
Jessie 8.1 with up to date configuration, when i try to start virsh to
launch one Debian armhf LXC container, i have following error :
root@srv-cubie2-2:~# virsh -c lxc:// start srv-dhcp-1 --console
error: Failed to start domain srv-dhcp-1
error: internal error: Failed to allocate free veth pair after 10 attempts
But this error is the second error, (please look at at trace...)
Configuration is :
