Hi all, I''m using Xen (stable tarball 3.0.2). I want to connect a modem to my serial port (ttyS0). After setting "xencons=off" in the module line of my grub, Xen doesn''t use this port itself (dmesg said nothing about ttyS0). So I did a "modprobe parport" and a "modprobe 8250" says: FATAL: Error inserting 8250 (/lib/modules/2.6.16-xen/kernel/drivers/serial/8250.ko): Unknown symbol in module, or unknown parameter (see dmesg) dmesg: 8250: Unknown symbol uart_get_baud_rate 8250: Unknown symbol uart_resume_port 8250: Unknown symbol uart_register_driver 8250: Unknown symbol uart_suspend_port 8250: Unknown symbol uart_remove_one_port 8250: Unknown symbol uart_update_timeout 8250: Unknown symbol uart_unregister_driver 8250: Unknown symbol uart_get_divisor 8250: Unknown symbol uart_match_port 8250: Unknown symbol uart_add_one_port 8250: Unknown symbol uart_write_wakeup Did anyone have experience in this error / what went wrong? Do I have to compile my own Xen0 kernel with serial port support?

Hello,>From the DomU you have access to the physical serial port, that is to say,with lspci it leaves to you in the DomU? If it leaves to you in lspci, then when loading the module your DomU to use it. In order to give access to the DomU to a port, your watch the documentation<http://www.cl.cam.ac.uk/Research/SRG/netos/xen/readmes/user/user.html#SECTION03230000000000000000> . What kernel do you use in DomU?, this one has support for serial port. -Javier- 2006/7/19, Holger Schultheiß <hoschult@web.de>:> > Hi all, > > I''m using Xen (stable tarball 3.0.2).

Short story: still not working. I''ve had the very same problem since day 1. xencons=off indeed works, but ttyS0 isn''t created at boot. I even tried building my own kernel, but that didn''t work either. Though, I must admit, I have not built my own kernels very much, so I may have made a mistake. If you solve it, PLEASE let me know here. My recently purchased Smart-UPS is now dumb. :( Regards, Ranbir -- Kanwar Ranbir Sandhu Linux 2.6.17-1.2141_FC4 i686 GNU/Linux 14:26:25 up 1 day, 7:56, 2 users, load average: 0.53, 0.70, 0.53 _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

I wanted to try it but my XEN installation is running quite nice despite this issue ;) Regard, Markus _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

I don''t know what''s going on there.

Is there Java applet console for Xen? If not, will it be possible to build one by compiling the python source using Jython? Has anybody attempted this. I have seen xenman, and also enomalism, but neither has a java applet based console, which would have been oh so convenient. Can anybody give me some pointers on where to start? Doesn''t the xend actually allow remote consoling? There do exist a java applet console for Vnc, and it is fully functional and extremely useful, so I was just wondering if it is possible make it work with Xen. MS Virtual Server also comes with a browser interface, albeit based on activex, thus making it unusable on Linux browsers. Any comments on this would be appreciated. -- :: Ligesh :: http://ligesh.com _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

I downloaded the binary install and it seems that somehow serial_core isn''t built, either into the kernel or as a module. --- tony@thor:~/Downloads/xen-3.0.2-2-install/install/boot$ egrep CORE config-2.6.16-xen CONFIG_ELF_CORE=y # CONFIG_I2C_DEBUG_CORE is not set CONFIG_DVB_CORE=m CONFIG_PROC_KCORE=y --- Don''t know how or why. You have 2 options as far as I can see: a) Convince someone to build you a serial_core.ko that will work with the binary install of Xen. b) Built xen from source yourself. I can do "a" for you but not for a few days sorry.

I seems that in the binary install the CONFIG_XEN_DISABLE_SERIAL has been set to yes. This allows the xen console driver to provide a console on waht will appear as ttyS0 in the domUs. If I read this correctly you''re in a situation where you need to build seperate dom0 and domU kenrels from source. Have a look at: http://wiki.xensource.com/xenwiki/InstallationNotes for guidance.

Thanks a million. Now I can go and try to fix this - finally! I assume then when RHEL 5 hits the streets, it will ship with the two kernel option for dom0 and domU, otherwise ttyS0 is toast.
