I am using 32-bit Xen and Xen heap is limited in size.

<div>I wrote some code in Xen hypervisor. It allocates an array to track th=
e runtime statistics. When I use _xmalloc to allocate the array from xen he=
ap, it fails with &quot;No enough memory&quot;. I check the Xen heap via &q=
uot;xm dmesg&quot;, it shows 9MB, while the size of the array is around 14M=
B. 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? </div>
