Hi Vish,

 As you pointed out I applied nova.console_enc.diff available on https://bugs.launchpad.net/nova/+bug/758054, but the issue was not fixed. Still getting the same error :

The diff that actually made it into trunk is here:

https://code.launchpad.net/~yorik-sar/nova/lp758054/+merge/59344/+preview-diff/+files/preview.diff

It should be as simple as adding that to your compute hosts and restarting nova-compute

Hi Vish,

  The patch you suggested fixed the utf-8 error. Thanks for the help.
