I update here to bitkeeper of yesterday (2004/10/05) and I got
the oops below.
The rpm is working fine and test program posted before prints lots of
dots only. I''ll keep my eye on it.

I have two domains 0 and 1. Domain 1 is locked up, and I want to issue a command to run in domain 1 from domain 0''s console. Is there a command for this? If not, which files should I look at to implement this? I''m using Xen 2.0 and Linux 2.4.27.

I''ll keep my eye on it.Can you please retry with writable page tables disabled? Rebuild you kernel image after disabling ''Xen'' -> ''writable pagetables'' in the kernel build configuration. The crash you see is pretty serious -- must be memory corruption or similar, and we already know that there is definitely a problem with writable page tables. It''d be nice to be sure that they are the cause here. -- Keir ------------------------------------------------------- This SF.net email is sponsored by: IT Product Guide on ITManagersJournal Use IT products in your business?

Is there a command for > this?If the console for the other domain is also locked up (as well as sshd etc), then I expect the domain is toast anyhow. (You can grab the console with ''xm console <domain_name>''> If not, which files should I look at to implement this?

Flavio, A serious writable pagetable bug was fixed last night, so the best thing to do is try out the latest version of the repository WITH writable pagetables!
