[Xen-users] Why cannt I boot 128 ttylinux VMs?

["Liao, Guangdeng" <guangdeng.liao@xxxxxxxxx>]

Hey all,

I am a new Xen user and trying to boot up 128 VM on the machine with 16G
memory. All VM images are ttylinux. When I booted up 116 Virtual
machines, I can not boot VM anymore. Once I create a new VM, the latest
VM on the machine would be kicked out to hold 116 VM simultaneously.
Since I set VM memory to 32M, the Memory should not be an issue. I am
wondering why I can not boot 128 VM and why the limit of VM is 116? Is
there any way to configure the limit? I am looking forward to your help.
Any suggestion or idea would be highly appreciated!

I am using the latest xen 3.1 version and the configuration file for VM
is as followings:

        kernel = "/boot/vmlinuz-2.6.18-xen"
      memory = 32
      name = "ttylinux"
      vif = [ 'bridge=xenbr0' ]
      nics = 1
      disk = ['file:/home/danny/guest-os/ttylinux/ttylinux-xen,sda1,w']
      root = "/dev/sda1 ro"


Thanks in advance
Best,
Guangdeng
