Dom0 memory allocation

 Hi all,
In the Oracle VM Installation and Upgrade Guide for Release 3.1.1 after completing the installation of OVM Server it states:
You may encounter performance issues if the dom0 memory size is not set appropriately for your needs on the Oracle VM Server. For example, you may encounter performance issues when running more than 10
virtual machines on an Oracle VM Server.

To change the Dom0 memory allocation, edit the /boot/grub/grub.conf file on the Oracle VM Server and change the dom0_mem parameter, for example, to change the memory allocation to 1024 MB, edit the file
to be:

kernel /xen.gz console=com1,vga com1=38400,8n1 dom0_mem=1024M 

Howdy, Stranger!
