I have a small test box running CentOS with kernel 2.6.18. My problem is that allocating memory with xm or virsh often fails to work, but produces no error. Other times, it works fine. Dom0 has plenty of memory available, and the guests are configured with min and max memory settings (and I'm staying within those limits).

What I'd like to understand is what affects whether or not xen put the memory where I tell it. Sorry if this is overly broad, but it's perplexing.. no error messages, sometimes the memory just never appears in the guest, and I don't see any different conditions when it works and when it doesn't.
