 Thanks.
 I have joined the channel.
 
 AIO doc says minimum 8 vcpu's are required.
 Is that a mandatory requirement?
 My laptop has less vcpu's.

if its just a test deployment you can run with less
we normally recommend 8G for ram and 8vcpus for an all in one deployment of openstack but it will work with 4
you just wont be abel to run many vms. on the ram side i have deployed all in one node in 6G of ram but again that
teands not to leave much room for vms.

i havent realy used OSA but the requirements should be more or less the same.

 Amey.
