Re: [Xen-users] About XEN

[Stephen Yum <steveyum@xxxxxxxxxxxxxx>]

Currently I'm running Xen 3.0.2 x86_64 (AMD64) version on a machine  
that is as follows:
   * Dual Opteron 265
   * 12GB of RAM
   * 2 x 300GB Maxtor SATA drives hooked up to 3ware 9550 in RAID0
   * Tyan S2882 Mobo

I have about 20 domUs running perfectly, all either CentOS or Debian  
flavor. I haven't tried the IA-64 platform, but as for x86_64, no  
probs at all.
Except one... In 32-bit land, I was able to run dom0 fine with just  
64MB of RAM. But in the 64-bit land, dom0 crashes with 64MB, gets a  
little farther with 128MB, but really really requires 256MB to run  
decently. Every time I check, mem usage on dom0 is ~250MB or so. On  
my 32-bit Dell, mem usage is about 20MB.
I have yet to figure out why the hell the AMD64 machines requires so  
much RAM and what it's doing with it.
