Hello,
I've been running Xen with 32-bit dom0s and domUs for a little over a year now
(good stuff!), and have just started moving to x86_64. Starting from an x86_64
non-Xen Gentoo installation, I've built the necessary packages using Gentoo's
Portage, but find that the resulting hypervisor is only 32-bit, which I presume
to be the underlying reason it won't boot the 64-bit dom0. I'm trying to
figure out what is preventing me from getting a 64-bit hypervisor.
Interestingly, the xen-syms-3.3.1 file is 64-bit, so I don't think it's a basic
mistake in my compilation settings:
--------------------
root@Xen1# ls -l xen.gz
lrwxrwxrwx 1 root root 12 May 18 02:30 xen.gz -> xen-3.3.1.gz
root@Xen1# zcat xen.gz | file -
/dev/stdin: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV),
statically linked, stripped
root@Xen1# file xen-syms-3.3.1
xen-syms-3.3.1: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), statically
linked, stripped
--------------------
I've been using http://www.gentoo.org/doc/en/xen-guide.xml and
http://en.gentoo-wiki.com/wiki/Xen as my primary references. Searching this
list and Googling haven't yielded promising results so far, although my
situation sounds very similar (aside from the hardware) to
http://lists.xensource.com/archives/html/xen-users/2006-08/msg00018.html .
I've started digging through the temporary working directories used by Gentoo
during installation, as well as the output from 'emerge' itself (captured with
'script'). However, my eyes have begun to glaze over.
Various pieces of system information follow - sorry if it's overly verbose.
I've omitted my xen-sources kernel configuration settings for the moment, since
I believe the hypervisor compilation to be independent anyway. Have I simply
managed to overlook something or to do something stupid? Any pointers would be
appreciated. If I've overlooked a more appropriate mailing list (something
Gentoo-specific, perhaps?), I apologize.
