Version 6.0.10 r132072 (Qt5.6.2)
Recently, within the last 3 updates, my CentOS 7 (3.10.0-957.27.2.el7.x86_64 #1 SMP Mon Jul 29 17:46:05 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux) VMs intermittently hang when I select ACPI Shutdown after right-clicking the Group header bar. Prior to this the VMs would shutdown with no issues. I see that there are some older posts with similar issues, but I don't see a resolution.

Is this a known problem?

Thanks!

So, you have multiple VMs in a Group and when you choose to shut them all down, some (or all?) of them don't get the ACPI Shutdown signal?
