Subject: maximum memory size allocated by _xmalloc
Date: Wed, 11 Jul 2012 18:13:27 +0900 [thread overview]
Message-ID: <008601cd5f45$6eff7530$4cfe5f90$@core.kaist.ac.kr> (raw)
Hi all,
I'm currently inserting my own code to adjust the several existing memory
ballooning works.
To accomplish it, I manage some kind of statistics in Xen memory area.
Using _xmalloc, I've allocated certain size of memory chunk for the data
structure. ( I varied it from 10kb to 24 MB.)
When the size is equal to 24 MB, xen won't boot anymore. (stuck during the
xmalloc, according to my debugging. _xmalloc returns NULL.)
There was no problem when the size is below 12MB.
Is there any limitation such as max memory size for _xmalloc?
I suspected xen heap size, but, it is no longer adjustable. Right?
I hope somebody can give me a clue. Thanks.
