RFC2217 extends telnet to provide changing things like baud rates and parity inline... The Python module PySerial includes both a client: http://pyserial.sourceforge.net/examples.html#miniterm and a server: http://pyserial.sourceforge.net/examples.html#single-port-tcp-ip-serial-bridge-rfc-2217 Looks like ports has sredird that does the same for a server... So, you could use a server attached the nmdm plus ssh port tunneling to provide access... I've been tempted to write a program using cuse that would present a modem device that could be used w/ tip or cu and connect to an RFC2217 server on the back end giving you complete remove access to all settings of the serial port, but haven't gotten around to doing that yet... -- John-Mark Gurney Voice: +1 415 225 5579 All that I will do, has been done, All that I have, has not. ___ freebsd-virtualization@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-virtualization To unsubscribe, send any mail to freebsd-virtualization-unsubscr...@freebsd.org

Willem Jan Withagen mailto:w...@digiware.nl Tuesday, January 20, 2015 8:37 AM What is the easiest way to propagate the full-duplex tty stream from a SSH-login to a /dev/nmdmA. somewhat expectedly, i use http://www.freshports.org/sysutils/rtty/ for this. with a restricted shell, i can offer console access to guests via ssh. cu also works, but lacks rtty's background logging. -- Paul Vixie ___ freebsd-virtualization@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-virtualization To unsubscribe, send any mail to freebsd-virtualization-unsubscr...@freebsd.org

Hi Allan, I elided a bit of detail — actually I'm using libvirt, which then uses bhyveload. So we need to create some other generic loader, and fix libvirt to invoke that instead? What does bhyve need the loader to do?

See this discussion: https://lists.freebsd.org/pipermail/freebsd-virtualization/2014-October/002857.html Hi Craig, Thanks, I've read that thread. Ideally libvirt/bhyve can just use a generic loader rather than special casing bhyveloader and grub2-bhyve. How are you envisioning one indicating to libvirt which loader to use / what the guest OS is?
