Hello Jaison,

Can you please attach the ovf of the 3.0 VM, including the disk, by running on storage server:

tar -zcvf vm3_0.ovf images master

Thank you,

Verified in rhevm-3.4.0-0.10.beta2.el6ev (av4).

Verification steps:
1. Create an NFS export domain with data provided in comment 5 - it contains the VM image & OVF file of a Windows VM exported in RHEVM 3.0.
2. Import the VM (check that 2 monitors are shown in the VM details sub-tab on Import Virtual Machine(s) dialog).
3. After the import is complete, check the imported VM has 2 monitors set as well.
4. Run the VM and on host check the corresponding qemu process.

The qemu parameters must contain *only one* occurence of "-device qxl,id=video...", which indicates a second display device (thus two monitors in total).

All display-related qemu parameters then look like:

-vga qxl -global qxl-vga.ram_size=67108864 -global qxl-vga.vram_size=33554432 -device qxl,id=video1,ram_size=67108864,vram_size=33554432,bus=pci.0,addr=0x5
