Nova may not start instances when OS is installed with locale not en_US

[Jorgegv]

Nova fails to start instances on compute nodes when the base OS (CentOS 7) is installed with a locale other than en_US.UTF-8 (e.g. es_ES.UTF-8).

To avoid this bug, the base system should always be installed with locale "en_US.UTF-8" (US English) on all nodes, esp. Compute nodes.

This has been reported to RedHat RDO here:

Not a documentation issue. Moving upstream.

What's the error in the nova logs when it happens?

[Jorgegv (jorge-gonzalez)]

All tech info, including logs and explanation of why the error happens,
is included in the RH bug (link provided).

Shall I copy all info from there? Don't get me wrong, I have absolutely
no problem in doing so, it's just that it seemed more practical to add
a link from here to there...

    Fix bad exception logging

    When the locale is not en_US, then we fail miserably.

This bug is invalid and is a case of a bad translation

http://paste.openstack.org/show/190502

# -*- coding: utf-8 -*-

print("good:")
print(u"test %s" % u'á')
print("good:")
print("test %s" % 'á')
print("bad:")
print(u"test %s" % 'á')

[Matt Riedemann (mriedem)]

Concatenating the exception which might have a unicode string in it with the ascii debug log message is a bug and was fixed here, but there is a better way to fix this, which is bug 1430383.
