[Xen-devel] Upstream QEMU and Xen unstable not working
Bug resend.
This bug was reported about one month ago. QEMU fails to start with
Xen unstable. I found that it has not been fix with latest Xen
unstable. BIOS is Seabios (with Xen patch).
Xen-unstable a2457fc25c83872a5646c93f1e31958a2f5951e9
libxl: add LIBXL_MAC_{FMT,FMTLEN,BYTES}
Modelled after LIBXL_UUID_... (where I also add FMTLEN).

QEMU cf973e469bd9d47c0460347764c1315a6180e13c
set ELF_HWCAP for SPARC and SPARC64
setting ELF_HWCAP fixes dynamic library loading for Linux/sparc64
This patch allows loading busybox from Debian 6 initrd

These are not the problematic commits, I didn't do a regression
test. I just choose my latest commits as testing base.
Also, please note that
Xen-unstable a8f9242a7021a1febdc2ff7f8c6f6b66ee7e6745
does not trigger this bug.
Stefano and Anthony, you once said that you were going to setup a
public QEMU repository for Xen, how is it going now?
Wei.
