Title:
binfmt support not working for x86 host and x86_64 guest
Status in QEMU:
Expired
Bug description:
this is a problem in the qemu-binfmt-conf.sh script and maybe
somewhere else. the version i checked is the current github mirror
https://github.com/qemu/qemu/blob/master/scripts/qemu-binfmt-conf.sh
i am running linux mint 19 32bit on a 32bit x86 cpu and i want to run
some applications that are only available as x86_64 packages. i use
multiarch and qemu and it works for simple applications like cacafire.
however i want to run the application natively from the shell without
having to use qemu-x86_64 <path>. i also installed the binfmt-support
package. when i run update-binfmts --display then an extry for x86_64
is missing and transparent execution is not working.
the problem seems to be in the qemu-binfmt-conf.sh script. it disables
the creation of entries for cpus of the same family. this is not a
problem if you are using a 64bit cpu because 32bit binaries run on it
natively but it doesnt work in the opposite way. hacking line 310 from
if [ "$host_family" != "$family" ] ; then
to
if [ "$cpu" = "x86_64" ] || [ "$host_family" != "$family" ] ;
then
and running it with the --systemd ALL parameter causes a x86_64 config
file to be created. it still doesnt work but that might have different
causes.
