Re: [Xen-devel] Re: [PATCH] balloon bugfix on -TESTING

[xuehai zhang <hai@xxxxxxxxxxxxxxx>]

Hi aq,
I tested the -testing tree by applying your patch and i can successfully balloon the domain's memory 
 above the initial allocation now. BTW, you can give either bytes, or m (mega bytes), or k (kilo 
bytes) to the "mem=" kernel command line parameter in the "extra" option of the domain's config file.
Thanks!
