<ul style="padding-left: 9pt"><font size="3" face="serif">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>
<br>
