you can find the "rescue" function in Nova.</span>
<div style="font-family:arial,sans-serif;font-size:13px">
-------------</div>
<div style="font-family:arial,sans-serif;font-size:13px">
Here're simple steps:</div>
<div style="font-family:arial,sans-serif;font-size:13px"><br>
<div>1. Add a "rescue_image_id=$(imageId you
want to choose)" in nova.conf firstly. If not
given, the origin image will be used.</div>
<div>2. Secondly, waiting for your VM turn to
"ACTIVE" after you execute "nova rescue $vmid"
command.</div>
<div>3. Access to your VM via VNC and fix it. </div>
<div>4. Execute "nova unrescue $vmid" back to
normal.</div>
