Thread-topic: Where can I get a balloon driver to test PoD
I want to try PoD to test some code. After setting different value to maxmem 
and memory config option, I can see PoD cache count in the domain dump debug 
However, I can't find a balloon driver to do more testing. I don't want to use 
2.6.18 kernel because it is really a bit of legacy now. In pvops dom0's 
stable-2.6.32-x branch, I noticed driver/xen/balloon.c only support PV xen 
domain as followed code stated. Simply remove the check cause guest panic.

Does anyone know where I can get a working balloon driver for PV-on-HVM guest? 
Does any branch in pvops dom0 support this? And, George, can you share me some 
experience that how did you test your PoD patch?


static int __init balloon_init(void)
    unsigned long pfn;
    struct page *page;

    if (!xen_pv_domain())
        return -ENODEV;
