In Nova, specifically the libvirt driver's spawn process (nova/virt/libvirt/driver.py), I've noticed that an attempt is made to launch an instance even if a failure occurs before the libvirt XML is assembled. In this case, I'm referring to when errors are logged but no corresponding exception is raised. Why is the launch not aggressively aborted if errors occur during setup? -- Peter Hamilton -------------- next part -------------- A non-text attachment was scrubbed...
