Kernel cmdline args can be passed to xen pv domains even when a bootloader is specified. The current config-to-sxpr mapping ignores cmdline when bootloader is present.
Since the xend sub-driver is used with many xen toolstack versions, this patch takes conservative approach of adding an else block to existing !def->os.bootloader, and only appends sxpr if def->os.cmdline is non-NULL. --- src/xenxs/xen_sxpr.c | 6 ++++++ 1 files changed, 6 insertions(+), 0 deletions(-)

ACK, assuming the test cases still pass - I'm surprised this doesn't require any testcase fixes Daniel -- |: http://berrange.com -o- http://www.flickr.com/photos/dberrange/ :| |: http://libvirt.org -o- http://virt-manager.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: http://entangle-photo.org -o- http://live.gnome.org/gtk-vnc :|
