Hi Kevin,
Running devstack in a VM is perfectly doable. Many developers use
devstack inside a VM (I run mine inside a VM launched using libvirt
on KVM). I can't comment on the issue that you're encountering,
but perhaps something wasn't configured correctly when you launched the
VM?
Best Regards,
Solly Ross
