[Pkg-libvirt-maintainers] Bug#884753: virt-sandbox: crash (SIGSEGV) when starting two instances at the same time

Tue Dec 19 05:21:54 UTC 2017
Package: virt-sandbox
Version: 0.5.1+git20160404-1
Severity: normal
Usertags: crash
When I start two instances of virt-sandbox at the same time, the second
one of them crashes and the first one gets an error. The error message
is different depending on how long the second one waits to start. It
seems like each instance is using shared resources but shouldn't be.
