Sorry, I meant to mention this yesterday on-list... I've removed the 
"nonblocking serial_getc" hack from Xen, which broke H_GET_TERM_CHAR 
support. However, the normal Xen console driver (which hijacks 
/dev/ttyS0, at least in dom0) is working fine for both input and 
output. So make sure you aren't using /dev/hvc0 for domain console 
output or a getty.

I don't object to these changes, but they are not all related to 
vterms. Let's try to keep our changesets clean, please.
