Title:
VFS: Cannot open root device "LABEL=cloudimg-rootfs" or unknown-
block(0,0): error -6
Status in OpenStack Compute (nova):
Incomplete
Status in linux package in Ubuntu:
Incomplete
Bug description:
Description
===========
An kvm instance failed to boot with a kernel panic after hitting this error:
VFS: Cannot open root device "LABEL=cloudimg-rootfs" or unknown-
block(0,0): error -6
Steps to reproduce
==================
This doesn't reproduce reliably, it seems to be a race condition.
* I started an instance through the API. It had not attached storage,
and was attached to a single network. It used an Ubuntu Xenial cloud
image which booted successfully on a different instance on a different
compute node.
Expected Result
===============
* I expected the instance to boot successfully
Actual Result
=============
* The instance failed to boot with a kernel panic:
http://pastebin.ubuntu.com/23911493/
* I used virsh destroy to stop that instance, then started it again
through the API, and it worked.
Environment
===========
xenial/newtown/kvm/openvswitch, no attached storage.
