Title:
Simultaneous launch of multiple instances from horizon leads to
multiple LANs assigned to new tenant
Status in OpenStack Compute (nova):
Expired
Bug description:
Using folsom and VlanManager, if one launches multiple vm for a new
tenant/project by setting the number of instances to 4 or 5 then there
is a race condition and potentially two or more vlan/networks are
assigned to one tenant.
It seems to me that the assignment of a network to a tenant is lazy evaluated
until the first instance for the project is launched. This
can be confirmed by creating a new tenant and then doing 'nova-manage network
list'.
After launching the vms this is the output of 'nova-manage network list',
showing the multiple vlans assigned to the same tenant:
