Are there any plans to implement some sort of console access to domains from dom0? Right now if something happens and a domain doesn''t boot properly I assume the way to fix this would be to mount the vbd in dom0 and chroot yourself to it (haven''t gotten vbd''s working yet :). Some sort of console access (perhaps emulating a serial console) seems like a much more elegant solution.

I was looking to start using Xen within a week, but if one of the key features I plan on using a lot is going to be redone I may as well just wait.> > -- Keir-- Matt Ayres <matta@tektonic.net> TekTonic ------------------------------------------------------- This SF.

There''s a bit more finessing needed down in Xen I think, but nothing very major. Depending on how complex you want your vbd configurations to be, you could quite easily add some alloc/dealloc/manage-vbd scripts on top of xi_vbd_create and xi_vbd_add. I''m not sure how long it will take to get our own higher-level tools sorted. It''s top of our todo list, so it should start coming together in the next few weeks. -- Keir ------------------------------------------------------- This SF.

Hopefully I can make it in one week. -- Bin ------------------------------------------------------- This SF.

Sorry for not posting about this and saving people hassle; I was assuming (incorrectly!) that only local folks were using unstable. - if you want to play with more interesting setups you can try the xi_* tools (vbd_create, _add, _remove, _destroy, _list, _info) - xenctl will almost certainly /not/ be the chosen tool for management in the new world... however if there''s considerable buy-in we can probably manage to keep partial support for it. W.r.t. the problem with hdf1, can you post the output of the log from xenolinux when it boots (if you have it available?). The log from xen booting would also be useful. cheers, S.

Therefore, you don''t need a serial line to capture the Xen boot message, nor do you have to copy the message manually. -- Bin ------------------------------------------------------- This SF.

My main complaint is that whenever trying to run a simply command it takes forever and uses all CPU since it invokes Java.

I''ll immediately port xi_read_console_ring to xeno-1.1 and send in the patch to the list. -- Bin ------------------------------------------------------- This SF.

For very early crashes, serial line debugging is currently teh only option. Possibly we should implement scroll-back in the VGA console. -- Keir ------------------------------------------------------- This SF.
