[Jiang]

When create a vm with non-ascii name in devstack,nova sources from the master branch. logging report UnicodeDecodeError in nova-compute.log.

Needs nova version.

Do you have a more full stacktrace than this, or the nova-compute log itself? This doesn't tell us much about where it originates from.

[Matt Riedemann (mriedem)]

Looks like it's coming from the logging in this method:

I'm sure I've seen this before, and it's likely something in the network_info, and I think we have duplicates of this bug...

I think this should be related to the name of the virtual machine. This error occurs only if I name the virtual machine with a non-ASCII encoding.

such as name the virtual machine with a chinese name.
