V-Series Image Settings

========================

kt@openstack:~$ openstack image set --property hw_vif_multiqueue_enabled=true b0181c20-d192-4006-b681-09fd2df65c5d

kt@openstack:~$ openstack image show b0181c20-d192-4006-b681-09fd2df65c5d

 

Next Step Create flavor for V-Series

=====================================

Configure flavor for V-series settings

=======================================

 (?)openstack flavor set vseries --property dpdk=true --property hw:cpu_policy=dedicated --property hw:mem_page_size=1GB --property hw:emulator_threads_policy=isolate

FM SSH credentials: admin/openstack123A!!

==============================

Commands to get the default FM GUI Password:  wget -q -O - http://169.254.169.254/latest/meta-data/instance-id

Above one could be used for first time FM Login

FM http credentials: admin/openstack123A!!

==================================================

If you're not using DNS server edit the file "/etc/hosts" and add the openstack server ip.

This will help in resolving the URL during monitoring domain creation

Use ip from iproute2. (You need to also specify the prefix length though.)

ip addr del 10.22.30.44/16 dev eth0

To remove all addresses (in case you have multiple):

ip addr flush dev eth0
