...t, i''m trying to get a serial port working on my domU. I''m running debian etch (2.6.18-4-xen-amd64 and xen 3.0.3-1), same problem with debian testing I noticed that CONFIG_XEN_DISABLE_SERIAL is set to yes. But still serial access from dom0 works fine. after blacklisting the 8250/8250_pnp/serial_core drivers, i still cannot get serial access from domU (i do have the proper modules in domU). Does the CONFIG_XEN_DISABLE_SERIAL setting only affect domU ? Is there anything else i need to do ? Thanks, Sven _______________________________________________ Xen-users mailing list Xen-use...

Is serial port "passthrough" possible for the version of xen that ships with centos 5.2? I've disabled the xen hypervisor serial console, and can see the serial port in dom0. I've masked out the 8250, 8250_pnp and serial_core modules on dom0 and rebooted. xm create domain fails with the error that exactly 4 arguments are required and only 3 were given. Steps I followed: 1) I have xencons=off as a kernel arg for dom0, and when dom0 boots, it finds the serial port. 2) I have blacklisted 8250, 8250_pnp...

...erial port of the dom0 (/dev/ttyS0) typing this in the domU configuration file: irq = [ 4 ] ioports = [ "3f8-3ff" ] The domU starts without any error, but the serial port isn''t recognised. The /dev/ttyS0 device exists on the domU, and I blacklisted the serial_core, the 8250 and 8250_pnp modules on the dom0. What is the problem? Could you help me, please? Thank you very much! Bye. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Just something to be added: - This procedure doesn''t work with a Fedora 9 DomU - Maybe you have to blacklist some modules in the Dom0: AFAIK you have to rmmod (better: blacklist on boot using modprobe.conf) these modules: serial_core 8250 and 8250_pnp ----- Ursprüngliche Mail ---- Von: Federico Fanton <fake@panizzolo.it> An: xen-users@lists.xensource.com Gesendet: Freitag, den 17.
