[root@localhost libvirt]# ./Install
You will need to choose an appropriate configuration for installation of
the "libvirt" Performance Metrics Domain Agent (PMDA).

Something whacky there - no problems here, and this kind of catastrophic failure from pmdaproc.sh would be affecting everyone (and many QA tests).

Marko confirmed on IRC that after setting forced_restart=false the libvirt PMDA Install proceeds successfully.  Probably high time we made that the default, as we've been planning to for ages - I'll get that in for the next release.

Comment 2 Marko Myllynen 2016-10-03 07:09:55 UTC

Steps to reproduce:

1. Install Fedora 24 Server
2. Update, put SELinux to Permissive
3. Install PCP, enable pmcd/pmlogger/pmie
4. Install pcp-pmda-libvirt from updates-testing
5. Continue as in comment#0

Comment 3 Nathan Scott 2017-02-01 00:35:04 UTC

This bug can no longer happen since the forced_restart=true was removed from the Install script (i.e. since pcp-3.11.6).
