I have a C7 server with a physical RS-232 console, but the config should be similar. I did not have to generate a systemd service for this; systemd saw the console line and automatically started the getty without me having to generate a

Hi, I used to use KVM for virtualisation and have now moved back to it, but I have a problem. When i used to install the guest machine with virt-install i used to use the -x "extra args" part to set the console for the install and guest, but it no longer works. Here is the command i use: virt-install -n server01 -r 512 --os-variant=virtio26 -c /isos/c5u5.iso --nographics

Hello, HVM is now a viable alternative to PV in term of performances and low overhead but some functionalities very useful for linux servers are still missing. I''ve configured the domU and guest operating system to use ttyS0 as a console so I can see pxelinux, grub2 and then the operating system. Decent physical servers provide a way to redirect the BIOS and gPXE output to a serial

Alle, After upgrading from 6.4 to 6.5, our serial console configuration non longer work. We have the following upstart file: [cwfox at hilo ~]$ cat /etc/init/ttyS0.conf # ttyS0 - agetty # # This service maintains a agetty on ttyS0. stop on runlevel [S016] start on runlevel [23] respawn exec agetty -h -L -w /dev/ttyS0 115200 vt100 [cwfox at hilo ~]$ And the following in /etc/securetty:

Hi, I'm trying to install a qemu-kvm virtual machine on a Debian GNU/Linux squeeze amd64 host, using virtinst 0.500.3 and libvirt 0.8.3.

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

I've been installing CentOS via PXE and using a serial console interface. The installation works great. I notice that during the install process, the following line gets added automatically to /etc/inittab: co:2345:respawn:/sbin/agetty ttyS0 9600 vt100-nav Which package does this? Is it kudzu?

How does one use virt-install and kickstart ? I've seen others have success but I've had no joy thus far. BTW, my interactive virt-installs for centos6 guests work just fine AND I can do unattended kickstarts for vms by booting from centos6 install dvd and typing the kickstart commands from the boot: prompt. However, kickstart commands in --extra-args when used w/ virt-install just

Hey, I''m more a reader than a poster on this list but Recently I installed CentOS 6.2 with myoung XEN Dom0 kernel and 4.1.2 hypervisor, at first everything went smooth, DomUs run like a charm and so on, but my serial console is gone for good tried dmesg | grep tty which spits out: uname -r 2.6.32-131.21.1.el6.xendom0.x86_64 dmesg | grep tty console [tty0] enabled Weirdest thing when

Hi, I'm trying to get isolinux work with serial console; however, I fail. My means of testing is qemu -serial stdio -cdrom the.iso; when I use bootoption 'console=ttyS0', the linux kernel has no problems writing to serial and the serial output does appear in the terminal I've run qemu from, so I believe qemu is working alright in this regard. I've also had it working with

It seems as if /etc/inittab has undergone some changes. That doesn't seem to be related to my issues however. I am able to setup the grub.conf ( menu.lst if you like ) to use the serial console ttyS0 at 9600 baud and the usual bits. However I can not actually see the GRUB menu at boot time. I see nothing until the server begins to boot and then I can see everything. However the grub menu is

Is there a way to get GRUB2 and the kernel to run a "serial" console under KVM? I'm running a Fedora 20 desktop, with libvirt-managed VMs. When I run a CentOS 6 VM, I can set both the boot loader and kernel up to use ttyS0 and get a console compatible with "virsh console". When I try the same with a CentOS 7 VM, it doesn't work. If I set it to ttyS0, I just
