I'm not sure I follow what you are saying.  The provisioned VMs are still up when you shut PVS1 down, or do they freeze?  What do you see on the vDisk status icon on one of the targets?  If the targets are still working, you may have to refresh the console (F5) to see any changes.  If the targets are not working, are all of the services running on PVS2?  Where do you have the vDisks stored?

in when pvs2 down ,all vms start in PVS1     ,but when PVS1 is down PVS2 cant take over and not starting the vms ,   but when you start both PVS servers 3 Vms will start in both PVS

Then it's not a load balancing problem.  It's a configuration issue with the boot options.  You probably only have one server configured to respond the PXE requests.

Adding Login Servers using the Configuration Wizard
To add and configure the first Provisioning Server as the TFTP and login server using the Configuration Wizard:1.Run the Configuration Wizard and when presented with the TFTP option and bootstrap location dialog, select the Use the Provisioning Server TFTP Service option.
3.In the Provisioning Servers boot list, click the Add button to add additional login Provisioning Servers to the list. Use the Move up or Move down buttons to change the Provisioning Server boot preference order.
Note: In an HA implementation, at least two Provisioning Server must be selected as boot servers.

If you use DHCP with options pointing to a specific tftp server, you are unable to sepcify the second server for redundancy.
Here I use PXE with proper configured TFTP-Servers ... this works for me.
