I ran into a problem with the PAE version of the hypervisor. I'm looking at xen-hypervisor-3.0-i386-pae_3.0.2+hg9611-1_i386.deb from alioth, and I ran into a problem with PAE being disabled in the binary: $ zcat xen-3.0-i386-pae.gz | strings | grep PAE PAE=yes PAE disabled. PAE mode mismatch between Xen and DOM0 (xen=%s, dom0=%s) It should look like: PAE=yes PAE enabled, limit: %d GB PAE mode mismatch between Xen and DOM0 (xen=%s, dom0=%s) I was able to get it working when I built it by hand, so it's got to be something in the package rules. I'd fix it myself, but won't have time for a little while yet. :-( Thanks for the great work on packaging this everyone. ---Nathan
