I think we may need to do a work around in UI as debug report did.
If a user clicked "+" on VM page, then this request get 202 response.
but after next round of GET /vms query, this VM may still not displayed
in VM tab, making user want to issue create again or wander if POST
request properly handled.
So we may want to display a vm creating in progress icon to users in UI.
Definitely. I just had to leave that part implemented since I'm not so
