Hi gurus,

 

I used xen 3.4.2. I noticed that, every time I reboo= t my box, the dom0 occupy all available physical memory (except those used = by xen hypervisor), then /etc/init.d/xendomains try to boot domu specified = in /etc/xen/auto, then dom0 balloon out to free a portion of memory (of course the resulting memory should be = above dom0_min_mem) to meet the memory requirement of incoming domu.

 

My question is, is there a guarantee that the domu g= et contiguous physical memory? Or how can I guarantee that? (My memory capa= city is big enough for meeting all domus and dom0 memory requirements.)

 

What about xen 4.1.0?

 

Thanks in advance.
