[Pkg-libvirt-maintainers] Bug#1002016: libvirt-clients: virsh hangs without controlling TTY

[Detlef Vollmann]

Package: libvirt-clients
Version: 7.10.0-1
Severity: important
X-Debbugs-Cc: dv at vollmann.ch

Dear Maintainer,

   * What led up to the situation?
Using virsh to start a VM from fvwm.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
I start a VM from fvwm normally with such an entry:
Exec virsh start vm && virt-viewer vm

This stopped working after the last libvirt upgrade.
Using a script and strace I found that it opens /dev/tty shortly before
the end of the output, so I assume there's a problem here.
Running the command from the command line in an xterm works fine.

   * What was the outcome of this action?
The virsh process still shows up in 'ps', but doesn't show
any activity, doesn't end and doesn't start the VM.

   * What outcome did you expect instead?
That the program returns and starts the VM.
