As we move forward with Xen enablement, there's a desire for being able to access more than 4 gigs of RAM on 32-bit Xen hosts. The options for handling this are 1) Another kernel. This is bad due to a) we're running out of CD space already b) keeping things matched up between the HV and the guest kernels c) migration is worlds of pain with two types of kernels 2) Switch the 32-bit xen kernels to require PAE. For most "current" non-laptop hardware, this is a non-issue. It does mean that xen won't work a lot of earlier PentiumM laptops 3) Do nothing, tell people to use 64bit if they want more than 4 gigs of RAM 4) Make the PAE code handled at runtime. This is a pretty non-trivial amount of work :) Given these, we're looking at going with #2 and thus only having Xen work on PAE-capable hardware in the development tree. And we're planning to try to execute this switchover the beginning of next week. Note that this will not affect bare metal installs at all.

xen always needed p6 hardware (didnt run on k6-II for example), and AFAIK p6 supports PAE always, so not any lose here i think -- Greetz, Antonio Vargas aka winden of network http://wind.codepixel.com/ windNOenSPAMntw@xxxxxxxxx thesameasabove@xxxxxxxxxxxxx Every day, every year you have to work you have to study you have to scene.
