Re: [libvirt] [PATCH] virsh: Fix regression with duplicated error messages

Commit 4f4c3b13 (v3.3) fixed an issue where cleaning libvirt objects lost error messages, by adding code to copy the libvirt error into last_error prior to cleanup paths. However, it caused a regression: some errors are now printed twice, because libvirt still remembers in its thread-local storage that an error was set. For example: $ virsh -c test:///default snapshot-delete test blah error: Domain snapshot not found: no domain snapshot with matching name 'blah' error: Domain snapshot not found: no domain snapshot with matching name 'blah' Fix things by telling libvirt to discard any thread-local errors at the same time virsh prints an error message (whether or not the libvirt error is the same as what is stored in last_error). Update the virsh-undefine testsuite (partially reverting portions of commit b620bdee, by removing -q, to more easily pinpoint which commands are causing which messages), now that there is only one error message instead of two.
