Hi,

I have noticed that, in the code of linux/drivers/xen/balloon.c, there exists the snippet as this:

static int __init balloon_init(void)

{

unsigned long pfn;

struct page *page;

if (!xen_pv_domain())

return -ENODEV;

.....

}

Does it means the driver will not work in HVM? If so, where is the HVN-enabled code for that?
