Thank you Tomas for the reply,
Yes, I want to bring it back to normal state so it would run without
this rescue mode.
When I execute "nova rescue" and VM gets into RESCUED then
/var/lib/nova/instances/{uuid}/console.log is filled,
but when I do "nova unrescue" and VM is in ACTIVE state this log is
empty (I can see the process of the VM in the core machine).
I wanted to use "virtsh console instance-xxxx" as described here:
http://www.jaredlog.com/?p=1484 to get a console to the machine but hit
this error:

Hi guys,
I have an openstack instance that run out of storage on core machine and
the instance got paused.
I cleared up the core machine so it has more disk now but when I start
the machine I can't ssh in.
In rescue mode I'm able to ssh in but I want to unrescue the machine to
be able to use it again without creating a new instance and migrate
everything from this failed instance manually.
I enabled virtlib debug log but nothing interesting came up (or at least
I didn't notice), the only thing that indicates an error is:
"Domain id=53 name='instance-00000281'
uuid=f2715c2c-6d4e-5cf1-7606-f5552a59cb56 is tainted: host-cpu"
"nova list" shows the machine has the correct IP set but I'm not able to
ping it on private IP nor via floating IP.
I tracked the network configuration from libvirt.xml and it seems it's
configured correctly to connect to the internal bridge: "br-int" on Open
VSwitch.
do you have any idea what should I try to unrescue the machine to and
get it into active state?

Hi!
What does the log and console show when the VM is in normal state?
The rescue mode is not a magical solution to all problem. It just runs a
clean OS and attaches your broken one as a secondary disk. YOU have to do
the magic to rescue it.
