Description toon 2020-03-30 18:32:47 UTC

I use a script to take automated snapshots of my VM's.
It has been working for many years.
After an upgrading to app-emulation/libvirt-6.0.0-r1 it doesn't work anymore.
The script calls virsh snapshot-create-as <domain> <timestamp> --no-metadata --disk-only --atomic
Error message: Timed out during operation: cannot acquire state change lock (held by agent=remoteDispatchDomainSetTime)'

Reproducible: Always

Steps to Reproduce:
1. Take external snapshot using virsh
2. Get error.
3.
Actual Results:  
The snapshot fails.

Expected Results:  
The snapshot completes successfully.

It appears that a fix has already been implemented.
See https://bugzilla.redhat.com/show_bug.cgi?id=1792723
Time to dash forward to the next release?  This one doesn't seem too stable...
