Reading the file (e.g.\ -\path{cat /proc/xen/balloon}) prints out the current memory footprint -of the domain. Writing the file (e.g.\ \path{echo new\_target > - /proc/xen/balloon}) requests that the kernel adjust the domain's -memory footprint to a new value. - -\subsection{Setting memory limits} - -Xen associates a memory size limit with each domain. By default, this -is the amount of memory the domain is originally started with, -preventing the domain from ever growing beyond this size. To permit a -domain to grow beyond its original allocation or to prevent a domain -you've shrunk from reclaiming the memory it relinquished, use the -\path{xm maxmem} command. |
