[nsxv] Neutron timeout when creating VMs in parallel

[Alexander Arzhanov]

Steps to reproduce:

Try to create a lot of instances (maybe 20 instances in test lab) at the same time and you will see in /var/log/nova-all.log:

RequestTimeout: Request to http://192.168.0.2:9696/v2.0/ports.json timed out (HTTP 408

To fix this you need to increase the "timeout value for connecting to neutron in seconds". I suggest using a value of 900 seconds:

for FUEL 7.0:
/etc/nova/nova.conf
...
[neutron]
...
url_timeout=900
....

for FUEL 8.0:
/etc/nova/nova.conf
...
[neutron]
...
timeout=900
....

Haproxy timeout set to 600 second - this recommendation from vmware. Maybe set the 'url_timeout' also in 600 ?

[Alexander Arzhanov (aarzhanov)]

600 second a suitable option.

    Change url_timeout in nova.conf

    Change [neutron]/timeout in nova.conf, otherwise the parallel launch
    of the virtual machines may fail with an error.
