Thread-topic: [Xen-devel] ParaGuest cannot see 30GB memory

Xen can only see 16GB of memory in PAE mode. So the greatest amount of memory you can assign to guest is a little less than 16GB – dom0_mem.

I have buit Xen (32 bit) with PAE and can start multiple Paraguests with 4 gig memory, but cannot launch a single VM with more than 4 gb memory. I would like to launch 1 VM with 30GB or so memory. Are there any config paramters like kernel,/inittrd that need to be changed.


I have the ramdisk set to the initrd I used to boot xen with PAE.
