[question] how to boot linux in cell linux

[Zhangjun (V)]

Hi All,

 

I found there is a linux-loader demo in inmates. How can I use that to boot a linux?

 

Do you have any instruction?

Yes, check Documentation/non-root-linux.txt in git. Please let us know
if something is unclear or missing.

The documentation is not easily to understand. The following description means we can create, load and start a linux cell only through just one command?

------------------------------------------------------------------------------------------------------------------
To create, load and start a Linxu cell and use the first UART as console, issue

jailhouse cell linux /path/to/linux.cell /path/to/bzImage \
-i /path/to/initrd -c "console=ttyS0,1152000"

Yes, it's only a single command.

Is there any suggestion?

Make sile that jailhouse-cell-linux was properly installed and can be
found by the jailhouse tool. "make install" should suffice.

[Zhangjun (V)]

After make install, the result is the same.

Ah, sorry, missed that you are already running from the source
directory. Is ./jailhouse-cell-linux executable? Does "./jailhouse cell
linux" dump the usage messages for you?

There isn't any usage messages.

Sorry, After change the jailhouse-cell-linux file to the executable file. The error message change to:

execvp: No such file or directory

It is solved.

There is no python under /usr/bin. We rename python2.7.10 to python, and solve this issue.

Were there a "python" under a different path? Then I guess we need this
change:

diff --git a/tools/jailhouse-cell-linux b/tools/jailhouse-cell-linux
index 245ba13..4a125f1 100755

Also keep in mind this would be Python 3 on many systems. Although as we
strive for the version-agnostic code in config tool, this shouldn't be
an issue.

Yes, the script worked fine in my tests over Python 3.
