I got '500 Internal Server Error' when I clicked 'New Instance' button in a host,
I checked /var/log/supervisor/webvirtmgr.log and found there was an exception:

After debug, I found if there are file with messy code filename in user's home directory in host machine, then the page [host] -> [New Instance] will show a Error page
In django/template/base.py, it try to decode string of filenames as utf-8
[host] -> [New Instance] -> [Custom Instance] -> [HDD] list all files in home directory.
