Thread-topic: [Xen-users] Ram question

The "xm info" command will tell you this, among other things:

 

# xm info

total_memory           : 32766

free_memory            : 24128

 

This host for example has a 2GB dom0, with 32GB physical memory, of which about 24GB is usable for virtualization.  (The memory sizes are reported in MB.)

Hey all,

 

have a question about limiting ram in grub.

 

i have set my grub to have a config line of dom0_mem=800M which limits dom0 to 800megs of ram.

 

i want to ensure that xen will still be able to use the rest of the system ram for the vm's for the server has over 16gb of ram.
