[Xen-devel] Increasing Xen Heap on IA32?

[Jesse Gross <jegross@xxxxxxxxxxxx>]

I am working on a research project that is based around Xen and I am 
running into memory constraints with the default 10 MB heap size.  I 
have tried increasing directmap_mbytes in asm/config.h as well as 
increasing the size of the Xen virtual address space and changing the 
segment descriptors.  However, this results in an unknown interrupt 
message on boot after the message "Using APIC driver default".
There must be something else that I need to change to get this to work.  
I'm assuming that the unknown interrupt is caused by either a page fault 
exception or a segment violation.
Any ideas?

Jesse
