Hello, I''m unsure where I sent a bug report for linux kernel 2.6.27-git11. If I''m use the attached config, I get the kernel panic shown in the attached dmesg. Hope this can be fixed. greetings Torben Viets -- Torben Viets w Viets@work.de n@work Internet Informationssysteme GmbH o http://support.work.de Wandalenweg 5 r Tel.: +49 40 23 88 09 - 0 D-20097 Hamburg k Fax: +49 40 23 88 09 -29 HR B 61 668 - Amtsgericht Hamburg Gf Jan Diegelmann _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hello, with your patch I didn''t get any error, but if I start a machine with 128 MB RAM and increase it per xm mem-set up to 256MB, neither top or cat /proc/meminfo shows the new memory... With 2.6.18 this was no problem, is the balloon driver working correctly? PS: I''m using a 64bit kernel under xen 3.2 My config was attached on the first post...

Currently the balloon driver can only contract a domain, and re-expand it back to its original size. I have code to do expansion too, but it needs some work before being mergable.
