Re: [Xen-devel] failed to boot into kernel during osstest standalone mode

Hi Ian,

Thanks for your reply and it's really very useful to me.
I connect a serial port on test host machine instead of VGA and found the 
machine is trying to install OS from mirrors server. That's why hangs at 
"booting the kernel" screen on VGA view. 
But, the installing is failed, seams something wrong with my mirrors server as 
below:[refer to mirror_error.log for detail] and I will continue to try.

An error has been detected while trying to use the specified Debian archive

-------------------------------------

So, the test host machine will re-install a pure OS with preseed file, right? 
And, after the OS installation via PXE Server is completed, osstest will 
continue to run, right?
