If I set up my xen file as follows: disk = [ ''phy:loop0,loop0,w'', ''phy:loop1,loop1,w''] I realize I should USTL but it seemed to me I should expect blkif changed messages for each vbd. I''m only getting the messages once. i.e. I see this: ===========> blkif_status_change to 1 ===========> blkif_status_change to 2 ===========> evtchn for blkif is 3 ====> enable disk interrupt =========> controller connected For the first disk, and that''s it. Shouldn''t I see two of these sets of messages, one for each disk? Is my expectation wrong or is something else going on that I missed? thanks ron p.s. I actually now have two plan 9/xen users out there ... 2 more than I had a month ago. So a month ago there was one, now 3 ... at this rate we should take over the planet in no time. ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.

Geez, I go away from this for a few weeks and forget everything :-)> Is there some sort of problem with Plan9? What exact is happening? > The above statements are for Linux. I don''t know if things are somehow > different under Plan9..no, I forgot that there is only one event channel and one controller. I have to learn how to look for those other disks :-)> Is there an image of Plan9 somewhere? I''m currently rebuilding my main > machine and would love to throw a copy of it in the mix and be #4 :-)I can point you at the plan 9 server, but if you''re not running plan 9 that is of dubious value :-) I''ll try to put it on a web page somewhere soon. ron ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
