RE: [Xen-ia64-devel] why does xenU console stopat"Freeingunusedkernel memory:304KB freed"?

["You, Yongkang" <yongkang.you@xxxxxxxxx>]

Hi Fujita, Akio and Alex,

Could somebody give some hints and introduction about the usage of tty0 in 
XenU? I am always puzzled by this special setting. :)

Why present setting still use "console=tty0" in XenU config and why remove 
"mingetty tty0" from xenU inittab?

I noticed Alex send the patch about xencons several days ago. 

Best Regards,
Yongkang (Kangkang) 永康
