<font face="serif" size="3">Hi Kevin,<br>
Running devstack in a VM is perfectly doable. Many developers
use<br>
devstack inside a VM (I run mine inside a VM launched using
libvirt<br>
on KVM). I can't comment on the issue that you're
encountering,<br>
but perhaps something wasn't configured correctly when you
launched the<br>
VM?<br>
