[Qemu-devel] Build on i386

[jamesmikedupont]

Hi ,
I have patched the qemu to even build on i386. Now all the targets build,
but I cannot run all targets.

./i386-softmmu/qemu -L / /bin/ls
qemu: could not load PC BIOS 'bios.bin'

Does not work.

./i386-linux-user/qemu-i386 -L / /bin/ls
qemu: Unsupported syscall: 240
qemu: Unsupported syscall: 240
acl.c				config-host.ld	   kvm-all.c		  posix-aio-compat.o	
qemu-thread.c		 target-cris
acl.d				config-host.mak    kvm.h		  ppc64abi32-linux-user
qemu-thread.h		 target-i386

Works.


./x86_64-softmmu/qemu-system-x86_64 -L / /bin/ls
qemu: could not load PC BIOS 'bios.bin'

./x86_64-linux-user/qemu-x86_64 -L / /bin/ls

Do you know what softmmu means?  You should read QEMU
user manual.

This can't run given that your /bin/ls is an i386 executable.
