Description of problem:
Any attempt to execute a 32bit compiled application on an x86_64 Fedora 9 xen
guest fails, both Fedora-supplied applications and 3rd party applications.
Crashes with "cannot execute binary file", strace dumps "write(3, "strace: exec:
Exec format error\n", 32strace: exec: Exec format error) = 32" very quickly.
Version-Release number of selected component (if applicable):
Running Fedora 9 guest on RHEL 5.2 host, both x86_64 and fully patched, Fedora 9
guest with kernel 126.96.36.199-1.fc9.x86_64.xen.
100% reproducible. Happens every time. Problem not visible on identical x86_64
bit installation on desktop machine, problem also not visible on Fedora 8 or 7
x86_64 guest installations.
Steps to Reproduce:
1. On 64bit host, try executing for instance /usr/bin/mbchk from
grub-0.97-33.fc9.x86_64 - but any 32bit application will do.
It doesn't crash. :)
The only difference between the xen guest and a normal installation should be
the kernel, so I suspect there's a parameter in there not set?
IA 32 emulation wasn't supported on kernel-xen 188.8.131.52-1.fc9.x86_64.xen. It was
added on kernel-xen-2.6-184.108.40.206-2.fc9.
