Re: [Xen-users] DomU Memory Limitations

Using xm info it still shows 4gb ram available.

Yup. I have the exact same issue - except that it isn't a problem for me
since none of my domains need more than 512 MB :-). You need to compile
your domU kernel with 4GB RAM support. "cd xen-2.0/linux-2.6.11-xenU;
make menuconfig" -> Processor type and features -> High Memory Support
(off by default in domU kernels).
Yep, this is what I ended up doing and it solved the problem. I first
thought the problem was with the Dom0, and compiled it with highmem but
that did not help. Once I had the domU compiled with highmem that
solved the problem.
Thanks for everyones help.
Kind Regards,
Aaron
