My environment has 2 VM on Linux KVM which is installed on separate physical host, the VMs are basically website with database running on iis & mssql. One is active & second is passive.   Is there anything which can replicate and make the secondary VM live on failure of primary?Note: There is no storage devices connected to bare metal server.the VM are windows 2008 Any suggestion is accepted.
