Hi，Jainme.
I think curruent codes don't have solved the bug complelely. The key problems
the the following snippets are executed parallel.
class OpenNebulaHM < OpenNebulaNetwork
XPATH_FILTER = "TEMPLATE/NIC[VLAN='YES']"
def initialize(vm, deploy_id = nil, hypervisor = nil)
super(vm,XPATH_FILTER,deploy_id,hypervisor)
@bridges = get_interfaces
end
so bridges variable maybe have the same name bridge. because bridge is a ruby
instance variable，not a ruby class variable.

Hi,
yes, this is a known bug which is already solved in OpenNebula >= 4.0 by
implementing locking mechanisms.

Hi everyone！
I find a problem when we create two or more instances on one host at the
same time，we meet the error "device onebrxxxx alreay exists can't create bridge
with the same name".
The reason is that instances all try to create their bridge，although they
check whether or not their birdge is existed. because it's at the same time,
they all get a result that their bridge is not existed, and then they create it.
But when they really create, the same bridge has already been created by
other instances.
Has the problem been fixed now？ I use opennebula-3.8.1.
Look forward your answers!
dylan.
