I agree that. But I am assuming that If we implement virtual console, we can capture early console logs (but I don't know how to get these logs) and I can have log information if any of the non root cell crashes. Otherwise is there any way to get early console logs with ivshm-net. Regards, Anil -- You received this message because you are subscribed to the Google Groups "Jailhouse" group.
