Hi, I added a page on Xen 4.2 limits (based on info I know) at http://wiki.xen.org/wiki/Xen_4.2_Limits based on some information that Jan sent me a few months back. What I don''t know is whether there is a difference for 64 bit and 32 bit guests. Also I may be missing missing some important figures/stuff that people want to know. Feel free to reply to the thread or add to http://wiki.xen.org/wiki/Talk:Xen_4.2_Limits Regards Lars

No strong preference Lars

I''d be in favour of merging. Ian.

For example, the release features page says HVM guests have a limit of 1 TB (should be TiB) of RAM, but the 4.2 limits page says 512 or 256. Matt
Matt, thanks for pointing this out. Ian, I think you are right, we should kill the limits page. Ian, do you know which limits are correct? Maybe we should just add a Xen 4.2 column now.

The upper limit of memory for HVM guests is something I''m not sure about though (especially because I don''t know whether the tools impose any restrictions, as is the case for PV guests). Jan

There are a few ???''s and some stuff on Xen_4.2_limit seems to have been a reduction compared to http://wiki.xen.org/wiki/Xen_Release_Features, so I chose the upper limit (in particular for HVM) Any noteworthy new 4.2 features http://wiki.xen.org/wiki/Xen_Release_Features would also need to be added Lars
