I tried 2.0 with installer tests and a trusty guest on a trusty host. 
This test boots a VM with 2 CPUs from an ISO on a cdrom drive, with 
custom kernel, initrd and boot command line, communication is done over 
serial lines.

I found no problem so far. Just at the end of the run I got the 
following trace in the guest's syslog [1] that I didn't notice with 1.7. 
The version of the kernel is 3.13.0-11-generic.

The full command line to start qemu is [2]
