Well, I let you read the paper first :) It will answer all these questions.

In a nutshell,
Complicated: that always depends who you ask and relative to what you
consider something complicated. ELI changes some critical points in KVM.
Unsolved issues: there are some issues solves in theory but not implemented
Security holes: not if you are OK with the threat model we describe in the
paper
need paravirtualize the guest: no if you have x2APIC.
