TBH: I just couldn't find it. I tried to get some diagnostics when I started this work and couldn't find any place where the messages would occur. >> Use printk of mini-os in this situation. > > and this now ends up on the console and (for a debug h/v) in the xen dmesg, > is that right? The console of the xenstore domain seems to be a little bit special, as there is no component up to now writing the information needed to connect xenconsoled to the xenstore domain. This could be the reason I wasn't able to see any message printed via vfprintf. :-( So in the end it will be part of xen dmesg. And this is where it should be, as such messages will be needed in case of xenstore domain not working properly. And I think it's console can be accessed by any means only in case of a working xenstore. :-) Juergen _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel
