Re: [Xen-devel] Loopback images

[Paul Dorman <pauld@xxxxxxxxx>]

I for one would really appreciate the effort Mark. 

Another thing that I would really like to see is support for big memory (and 
I'm not implying that Mark should do this too! :o)  ). Eventually of course 
we'll be using 64 bit machines, but we will still have a number of dual Xeon 
machines in our cluster and being limited by the amount of RAM we can use is 
a potential concern (we'll be running MySQL databases on quite a proportion 
of the VMs). At the moment I have 4GB in each node, but I'd like to be able 
to raise that to 12GB. I know this is probably non-trivial, but I think it 
would be widely used, especially by folks with large numbers of 32 bit 
machines converted to use Xen. Am I correct in my understanding that the 
primary reason for not supporting big memory was due to problems with earlier 
Xen implementations? Is it still a very difficult problem? I'm still finding 
my way around Xen's architecture, so please forgive me if this is not a 
sensible question.

Regards,
Paul
