Choosing A Webhost:
A web hosting service is a type of Internet hosting service that allows individuals and organizations to provide their own website accessible via the World Wide Web. Web hosts are companies that provide space on a server they own for use by their clients as well as providing Internet connectivity, typically in a data center. Web hosts can also provide data center space and connectivity to the Internet for servers they do not own to be located in their data center, called colocation. more...

Hi Tony,

 

There is a bug about this issue. Please have a look at https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=180126

 

If want to use serial port input, I have to disable SMP. Following is a workable grub config to enable serial out input, but the kernel will be UP. I am not sure if there is any better solution.

 

title Fedora Core 5

        root (hd0,0)

        kernel /boot/xen.gz-xxx_FC5 dom0_mem=262144 com0=115200,8n1

apci=off

        module /boot/vmlinuz-xxx_FC5hypervisor ro root=/dev/sda1

console=ttyS0 console=tty0 pci=noapci

        module /boot/initrd-xxx_FC5hypervisor.img

 

Best Regards,

Yongkang (Kangkang) 永康

Hi there,

 

I've been working with the FC5 Xen stuff for the past few weeks after trawling many options for building a redundant server farm; It's a great build and congratulations to all who put this together.

 

I have a little issue with my serial console which is putting hte brakes on deployment though: I want to use the serial console on com2 (the default on the Intel mainboard I use) to give me the grub console, Xen console and Linux consoles.  I've had this working fine on previous releases from SuSE and others and on the current hardware.

 

When happens at the moment is that the machine boots, gives me the grub menu, where I can choose my boot system (so it's hearing my keystrokes) but once it proceeds into the Xen and ultimately Linux, it doesn't want to hear keystrokes from me any more: I can't CTRL-A (x3) and get the Xen console, nor the linux console which is configured in /etc/inittab.  I see the boot messages go past and get a login prompt, but no keystrokes get through or can control the machine.

 

It's making it tricky to send the box to co-lo as I can't get serial control if I take down the network, or Hypervisor control to reboot Dom0.

 

My rpms are:

 

kernel-xen0-2.6.16-1.2080_FC5

xen-3.0.1-4

 

and my grub.conf is:

 

default=0

timeout=5

#splashimage=(hd0,0)/grub/splash.xpm.gz

#hiddenmenu

#

serial --unit=1 --speed=9600 --word=8 --parity=no --stop=1

terminal --timeout=10 serial console

#

title Fedora Core (2.6.16-1.2080_FC5xen0)

        root (hd0,0)

        kernel /xen.gz-2.6.16-1.2080_FC5 dom0_mem=384000 com2=9600,8n1 console=com2,vga sync_console

        module /vmlinuz-2.6.16-1.2080_FC5xen0 ro root=/dev/VolGroup00/LogVol00 rhgb selinux=0

        module /initrd-2.6.16-1.2080_FC5xen0.img

 

I'd appreciate any guidance on silly things I may have done here; I'm banging my head on this one.

 

Many thanks,

 

Tony
