    Looks like you need to recompile from the SRPM. Do you have a 64-bit
    system to do it on?

I was looking for xen 3.2 64bit for the similar reason (32 bit domU crashes on 64bit dom0).I tried to build the source rpm of xen 3.2 (downloaded from http://bits.xensource.com/oss-xen/release/3.2.0/centos-5.1/xen-3.2.0-0xs.centos5.src.rpm) using rpmbuild on a CentOS 5.1(x86_64), and I got the below error: RPM build errors:
    Installed (but unpackaged) file(s) found:
   /usr/lib/xen/boot/hvmloader
Please let me know the changes required for building the src.rpm on 64 bit system? I was curious to know about the existing installation and I found that the package xen-3.0.3-41.el5-x86_64, installs all the binaries and libs in /usr/lib64/xen, but puts the hvmloader in /usr/lib/xen! Thanks,
Vinod
Huh. Interesting. RedHat's SRPM's are a bit more sophisticated than those for Xensource, traditionally, so I'm not shocked you found a discrepancy building it for x86_64. Perhaps you can review the differences in the .spec files and see how RedHat did it?
