Hi all, I wrote some code in Xen hypervisor. It allocates an array to track the runtime statistics. When I use _xmalloc to allocate the array from xen heap, it fails with "No enough memory". I check the Xen heap via "xm dmesg", it shows 9MB, while the size of the array is around 14MB. I try to reduce the array size, it succeed without any problem and works correctly. My question is how to increase the Xen heap because I will put other fields into array data structure. Or can I allocate from dom heap? If that, are there some sample code? Thank you.

I am using 32-bit Xen and Xen heap is limited in size. On Tue, Aug 10, 2010 at 11:25 PM, alex <leiye.xen@gmail.com> wrote:> Hi all, > > I wrote some code in Xen hypervisor.

You cannot increase the size of 32-bit Xen heap. You need to run 64-bit Xen. -- Keir On 11/08/2010 07:33, "alex" <leiye.xen@gmail.com> wrote:> I am using 32-bit Xen and Xen heap is limited in size. > > > On Tue, Aug 10, 2010 at 11:25 PM, alex <leiye.xen@gmail.com> wrote: >> Hi all, >> >> I wrote some code in Xen hypervisor.
