Maybe you can have the host drop a file with the information you need somewhere within
the guest's filesystem.

You could do that using a cron job on the host if you want it updated regularly. Or
you could have the guest request a refresh by touching a file and have the host detect
the request using the kernel inotify mechanism.

You could also ssh into the host from the guest, but it is not very secure.

Yes,you see my request

But why is that impossible?

I want to read some information through calling method of host,not
change any to host


Thanks
