John Ferlan reported the following Coverity warning:
In libxlDomainCoreDump() Coverity has noted a FORWARD_NULL reference:
2004 if ((flags & VIR_DUMP_CRASH) && !vm->persistent) {
2005 virDomainObjListRemove(driver->domains, vm);
(20) Event assign_zero: Assigning: "vm" = "NULL".
Also see events: [var_deref_model]
2006 vm = NULL;
2007 }
2008
2009 ret = 0;
2010
2011 cleanup_unpause:
(21) Event var_deref_model: Passing null pointer "vm" to function
"virDomainObjIsActive(virDomainObjPtr)", which dereferences it. [details]
Also see events: [assign_zero]
2012 if (virDomainObjIsActive(vm) && paused) {
2013 if (libxl_domain_unpause(priv->ctx, dom->id) != 0) {
2014 virReportError(VIR_ERR_INTERNAL_ERROR,
Removing the vm from domain obj list and setting it to NULL can be
done in the previous 'if (flags & VIR_DUMP_CRASH)' conditional. Fix
the Coverity warning by ensuring vm is not NULL before testing if it
is still active.
