This website show nova tool could create instance with multiple ephemeral disks, but how could I achieve that through openstack command or openstacksdk?
And I could find any clue through the openstack flavor create -h, it shows that only support one option Ephemeral Disk GB, and I can't figure out how to add multiple Ephemeral Disks.
Unless you already found the answer, this was added in python-openstackclient 5.5.0 References: 1,2,3
