That was my suspicion too but then I looked at virCommandRun implementation
and saw this:
if (!cmd || cmd->has_error == -1) {
virCommandError(VIR_ERR_INTERNAL_ERROR, "%s",
_("invalid use of command API"));
return -1;
}
if (cmd->has_error == ENOMEM) {
virReportOOMError();
return -1;
}
That is, if virCommandNew() returns NULL for either reason, by running
virCommandRun() on it, the original error (probably OOM) gets overwritten by
an internal error.
