I sent this patch directly to Gregor, and neglected to CC this list. Sorry about that. I''d like to make it so that there is no need to modify any Mini-OS source files when extending it with an application. All that is required is a change to Makefile, and a small change to kernel.c, printf.c, and string.c. I have enclosed the patch. With this patch, one could write an application in a

I am getting the following error when I try to bring up Mini-OS on x86_64 Xen (unstable: 9994). It is dying in xc_linux_build() causing xend to fault and restart. Any clue why this happening? Has something changed in the builder that Mini-OS needs to be aware of? PS: I tried reverting changeset 9993 (Allow linking of mini-os with application-specific object code), but still got the same error

hi, what''s the best way (if at all) to iterate through all of a domain''s page tables within xen 2.0.6? i need to find all references to a specific pte value (which is a given). essentially, a reverse page-table lookup. i''m hesitant to switch to 3.0, but if it''s easier to do what i want, just let me know. thanks, -A. -- Aaron Marks Distributed Systems Lab

This patch adds a test that tries to create a domain with only 16MB of RAM. It verifies that the domain is created and that the console works. Right now this test fails for me: the domain just dies immediately with no indication of why, or with any useful console data. Should we put a sanity check on xm''s create and mem-set commands that prevent the user from doing something we know

Hi, I need to get the exact downtime for doing a live migration with ms precision. (I am not bothered about whole migration time which is close to 1 minute.. I need to measure the live migration downtime during which the DomU is out of service.. the figure quoted in the xen documentation says it as ~60 ms.. ) I hope someone must have tried to measure this before. Can you suggest me ideas

...growing to Windows Registry-like proportions, making it very hard to keep up and the store hard to navigate. Perhaps we could agree not to write any default settings to the store to save some space and confusion?

hi, has anyone attempted to add grant tables, blockfront or netfront support to mini-os recently? Jacob _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

The attached patch adds support for simple waiting for a watched key to change to a certain value. This patch is necessary for the netfront driver (separate patch). regards, Jacob _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

The attached patch adds a netfront driver to mini-os. This version is much improved compared to the one previously posted (ie. it actually works this time).

hi, it seems I no longer need to pin l1 pages when running with writable page tables in xen-unstable -- e.g. I can now pin a l2 table without having pinned its l1 descendants first, without Xen complaining. Do I understand things correctly? thanks, Jacob _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

hi, I am trying to add xenbus watch support to mini-os, but am getting into a endless loop of watches firing over and over.
