Hello, I can't start tcmu-runner.service due to libphoton.so,

$ systemctl status tcmu-runner.service

So what is libphoton.so?

What OS are you using ? As I know there is no direct dependency on the libphoton.so from tcmu-runner.

Thanks for your reply, but I have other problems when start tcmu-runner:

$ sudo tcmu-runner 
tcmu-runner: symbol lookup error: tcmu-runner: undefined symbol: tcmu_iovec_length

and the /var/log/tcmu-runner.log show:

Then the following is the OS info I'm using:

BTW, where did you get the tcmu-runner package ? Have you tried to build from source yourself ?

commented

I never built this in Ubuntu yet. So not sure what has happened there!
