After migrating a VM (still running Debian Lenny 32-bit) using text consoles 
(default Debian configuration, no framebuffer I think), the VM is responsive to 
keyboard input but doesn't display new characters: only the cursor moves.
Otherwise the machine seems to run fine: I can log in and see the cursor moving 
at the prompt position for example.
Reverting the hw/cirrus_vga.c part of 7e72abc382b700a72549e8147bdea413534eeedc 
resolves the problem.

The setup is the same as for the e1000 bug: origin host is Debian Lenny 
32-bits, destination host is Fedora 12 32-bit.
