[libvirt] [PATCH V2] Do not drop kernel cmdline for xen pv domains

[Matthias Bolte]

2011/7/8 Jim Fehlig <jfehlig at novell.com>:
> 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.
>
> V2: Fix existing testcase broken by this patch and add new testcases

Are the leading and trailing spaces essential? If not I'd suggest to
remove them.
