MrCoderK commented 6 years ago

I use the host sysyem 16.04 and guest system 16.04. I installed the QEMU, but QEMU can not connnect the MONITOR_PM, the ssd monitor only show time,why? and i checked "thesocket->connetToHost(“127.0.0.1”, 9995)" and " serverAddr.sin_port = htons(9995);",there is no error. default

Thank you for attachments.

However, I need to check the execution messages after formatting the qemu disk image.

The following image is the sample screenshot (The messages in the screen shot can be different from yours.).

Thank you.

yeah, thank you .now i use the win7_64.iso as guest system, and i added "printf("the test had be builded:9995")" in front of "serverAddr.sin_port = htons(9995)" in ssd_log_manager.c, and I found that it did not execute. default default default

jedisty commented 6 years ago

I think FTL_INIT() was not called in your simulation.

Can you install 32-bit iso image in the same simulation environment?

Because I want to check whether it is matter of OS image.

Thank you.

thanks for your answer!
run there is error NO .[4] in the screen shot, but i can not find the in all the files so that i do not konw what cause the error,after installing the guest, the monitor still show nothing!

shehbazj commented 6 years ago

I would like to point out that I get the same error no (error number 4). We can get the cause for the error by printing the errorcode using strerror(). error code 4 corresponds to "Interrupted System Call". However, I am unable to understand what causes this error.

jedisty commented 6 years ago

Before checking the error number[4], you need to resolve the connection error.

Connected[-1] means that building the connection between server (SSD Monitor) and the client (QEMU) is failed.

Please change the port number of QEMU and SSD_MONITOR and re-compile both source codes (README describes how change the port number).

Thank you
