[Xen-devel] How to request contiguous memory for a domu

["Fan, Huaxiang" <hufan@xxxxxxxxxxxx>]

Hi gurus,

 

I used xen 3.4.2. I noticed that, every time I reboot 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 get contiguous physical memory? Or how can I guarantee that? (My memory capacity is big enough for meeting all domus and dom0 memory requirements.)

 

What about xen 4.1.0?

 

Thanks in advance.
