To start with I changed the kernel boot line adding: console=ttyUSB0,115200n8 and I setup minicom on the other machine. At first minicom would only give me unreadable characters so I assumed a baud mismatch and began testing other rates. At 57600n8 in minicom I get this: AT+GCAP AT+GCAP AT+GCAP this is with both the standard lucid kernel and the pv_ops dom0 kernel using console=ttyUSB0,115200n8. Any ideas on how to get more output? And I don't know how to configure xen line to add console or if usb serial console is even possible with xen. -Gerry
