I'd suggest reconfiguring kernel so it has CONFIG_BRIDGE_NF_EBTABLES, CONFIG_BRIDGE_EBT_T_FILTER and potentially others enabled.On 27.06.2014 13:33, abhishek jain wrote:
Hi
I need to run libvirt without ebtables support as it results in
following error while running VM....
sudo virsh start instance-0000000b

the kernel. Two possible causes:
1. Multiple ebtables programs were executing simultaneously. The ebtables
userspace tool doesn't by default support multiple ebtables programs

concurrently. The ebtables option --concurrent or a tool like flock
can be
used to support concurrent scripts that update the ebtables kernel
tables.
2. The kernel doesn't support a certain ebtables extension, consider
recompiling your kernel or insmod the extension.
