[Xen-users] what decides the number of DomUs that Xen supports?
The phicycal box has 2G Mem. I use Ubuntu as Dom0 and intend to start multiple VMs. Firstly, I create a .img file with 4G size and use it as Win XP with 256M Mem. Then I copy that .img file to other 3 locations, meaning that I wanna run 4 virtual XP simutaneously. However, as if my machine only supports three VMs to run concurrently. When I start the 4th (yes, it can start), after some time, no matter what I type in the Terminal in Ubuntu, it will tell me that "Segmentation Fault". What''s worse, the whole system(including both Dom0 and DomUs) also often halt there when 4 VMs run concurrently -- I mean no interaction between the computer and I. So I wonder does it mean the physical resources have run out or Xen has some problems when runing too many VMs?
