However, a handful of people have been working on incorporating PAE extensions to allow this on 32 bit x86. See http://lists.xensource.com/archives/html/xen-devel/2005-05/msg00660.html and do a search on the list for pae for additional info.I booted the demo CD under Vmware ESX and it worked fine. Xen guests under Vmware….From the specs, I see there is a 4GB limit. Is that limit per domain, for all guests, or for the entire server? Right now our vmware servers are dual CPU Xeons with 12-16GB of ram each, running about 15 guests.Is there an estimate when the 64 bit version will be released, and if it will support a mix of 32 and 64 bit, or will it all have to be 64 bit? (I don’t have any 64-bit hardware yet, but…) The 64 bit support is in the latest unstable tree, and is supposed to be stable when xen 3.0 is released. Only 64 bit guests are slated to be supported (at least initially) but a linux distros with 64 bit kernels can run 32bit apps without a problem. -Tupshin _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users
