Hi, Trying to get vga console and a serial console to both work. I can get either one to fully work but not both. When using serial, I do still get a login prompt on the vga, But not all the boot up output. Seems like half to the vga and the rest to the serial port I added lines to /etc/inittab # console port T0:12345:respawn:/sbin/agetty -L ttyS0 115200 And added to /etc/lilo.conf

Xen-users, I have what I think is a bug in the serial console interaction of Xen and Ubuntu. Essentially, the serial console appears to work just fine until it is passed off to dom 0 from Xen. Then it stops communicating with dom0, but still communicates with Xen, if I use the control-A escape sequence. Google will not show me anything related to this. I have local RS-232 serial console working

Hi, I am having the following setup: the kernel displays its messages to vga and to ttyS0. This works without xen. When I reboot my system with xen with the following options to xen and vmlinuz, xen.gz com1=115200,8n1 console=com1,vga vmlinuz console=ttyS0,115200 console=tty0 the system hangs up while booting the dom0 kernel. Has anyone such a setup working? The thin is, I want a console on

I am trying to get a CentOS 6.3 serial console to work with IPMI SOL. I think I have everything working but maybe the wrong baud rate on the getty: $ ipmitool -I lanplus -U root -H 10.0.0.14 sol activate Password: [SOL Session operational. Use ~? for help] ?????????? 10.0.0.14 is the DRAC IP address of the CentOS 6.3 box. It accepts the password and connects me to the console but then when I

I''m running xen 3.0.1 on the 2.6.12-26mdkxen0 mandriva kernel.

hi, It looks that Xen currently only support ISA serial port, which is onboard. Is there any plan to support the PCI serial port? Thanks, Neo -- I would remember that if researchers were not ambitious probably today we haven''t the technology we are using! _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com

Hi! My Liebert Power Sure PSPXT 450 with standard driver doesn't works, so I've done this modification and now it's works. # diff liebert_MY.c liebert.c 178 < ser_set_speed(upsfd, device_path, B9600); --- That is, I've only setup the port's speed. Can you update SVN code? Thanks Bye Beppe Ursino -------------- next part -------------- An HTML attachment was

How, exactly, does CentOS-6.3 with udev recognize an USB modem when it is plugged in. How is it indicated? What other configuration is required? I can find the modem in /sys/class/tty and I can get the attributes using udevadm but I do not see anything in ps that refers to the modem device. -- *** E-Mail is NOT a SECURE channel *** James B.

Hi- I am having a weird problem with setting dom0 kernel output to the serial console with Xen 3.0.4-1, below is my grub setting. With this setting if I don''t enter the grub menu and have the default boot to the first image, everything works fine and I can get output/input to the serial console. The problem is when I enter the grub menu and select the image to boot from, if I

Hi all I have a problem switch in our data centre, which is connected to a linux server via a serial cable. I know I can / could access the switch from my Windows PC back at the office, using hyperterm, but trying to access it using minicom just doesn't seem to work. I have changed the comms in minincom to use /dev/tty0 & the baud rate to 9600, yet I can't seem to connect with

Hello List, I'm ironing out details to upgrade a few systems to CentOS7. My servers have BMC with Serial over LAN support. In C5 and C6, I determined how to have BIOS/POST, kernel, and serial console access. I'm reading up on the method to accomplish the pieces with C7. Presently SoL output works, so I see BIOS/POST messages and the GRUB boot list. My changes to enable serial

We have been researching stuck zombie processes in our libvirt lxc containers. What we found was: 1) Each zombie’s parent was pid 1. init which symlinks to systemd. 2) In some cases, the zombies were launched by systemd, in others the zombie was inherited. 3) While the child is in the zombie state, the parent process (systemd) /proc/1/status shows no pending signals. 4) Attaching gdb to

Hi all: I am running pxelinux 3.72 with the corresponding menu.c32. I am setting up console access via: serial 0 38400 console 0 The rest of the config file entries should be safe enough: display pxelinux.cfg/helpfile say . Type any key for manual boot. <F1> or <Ctrl-F> 1 for help F1 pxelinux.cfg/helpfile then the usual MENU/label commands. When I use the same

Hi,, In Debian documentation website for "booting linux from USB" they say that the minimum details to be in syslinux.cfg are: default vmlinuz append initrd=initrd.gz bcoz i dont have a screen now, i wanna use serial port as a console from another laptop(supports serial). so how the above config file becomes? is it : Serial 0 Console 0 default vmlinuz append initrd=initrd.gz ??

The current early-printk support for ARM is rather hard-coded, making it hard to add machines or tweak settings. This series slightly moves some code to gather UART settings in xen/arch/arm/Rules.mk instead of the actual .c files. Also it allows two different machines with different settings to share the same driver, which the last patch exploits to add support the Calxeda Midway hardware. This

Hi all, A recent thread inspired me to try getting a proper serial console working on a Supermicro X9SCL motherboard with IPMI. However I find that while I see loader messages and the getty I enabled after boot I don't get any kernel messages which does somewhat limit the utility.. The BMC creates COM3 (/dev/cuau2) which works with getty. I modified /boot/loader.conf like so..

Hey, Does anyone know how I can capture both Xen & Dom0 console output on a "Virtual Serial Port" from HP''s iLO (Integrated Lights-Out) interface? Plain linux is no problem, but combined with Xen it seems to go haywire :-) So far I''ve been combining options and the only thing that actually gave me some output (albeit only the Xen console, not dom0) was this:
