[Xen-users] XenSerialConsole help + GRUB2 (Machine locks up on boot)

[Mike Viau <viaum@xxxxxxxxxxxxxxx>]

Hello,

I am trying to setup a Xen serial console for easily debugging the full kernel boot messages even if it crashes with the help from the following wiki pages:


http://wiki.xensource.com/xenwiki/XenSerialConsole
http://wiki.xensource.com/xenwiki/XenParavirtOps


I noticed the wiki was written for use with grub legacy. Therefor I am not certain if the serial console issue is with the way the grub2 package implemented serial consoles.


My problem is the machine locks up on boot after printing the message shown in the attached screen shot. I just get a blank screen with a blinking "_" prompt at the top left hand corner of the screen.


Does any have a non-standard PCI serial port Xen serial console working with grub2? What does your /etc/default/grub file and menuentrys look like? What does your /etc/inittab look like?


My motherboard does not have a serial port or even serial headers connectors on the board. Therefor I purchased an add-in serial card to obtain serial ports on the machine.


Motherboard:
http://www.intel.com/products/desktop/motherboards/DP55WG/DP55WG-overview.htm
http://ark.intel.com/Product.aspx?id=40078

Add-in serial card:
"Cables Unlimited IOC-2200 2-Port DB9 Serial PCI I/O Card" (http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?EdpNo=1431863&CatId=1422)


My GRUB2 configuration files are also attached from:

/etc/default/grub
/boot/grub/grub.cfg (trying to boot "Setting up Xen 4.0.0 / PVOPS 2.6.32-4-xen-amd64 with a serial console" entry)


Lastly a snippet from lspci -vvv
