OpenStack Compute (nova)

giving specific reason for noValidHost in nova show output

Asked by James Luhrsen

Hi,

I have a compute node that does not have enough usable RAM to boot my instance. The "fault" I see in
"nova show" is exception.NoValidHost(reason"").

The reason string is empty. Is there a way to have the specific reason show there?

Initially, I did not know why my VM could not boot, and I had to enable debugging in nova.conf in order to figure it
out.

I'm using Havana-2 code, so maybe this feature is available in the newer code.

Thanks,
JamO
