[Xen-users] Accessing console for Xen 4.0 with 2.6.31 pvops kernel on Dell Poweredge R610
I am currently using a Dell PowerEdge server R610 with Xen 4.0 installed and
the 2.6.31.13 pvops kernel.
I am accessing the server console using the iDRAC KVM feature of the dell
management console.
Does anyone know how to configure the console option in the grub menu so
that all the boot messages can be seen on the
mgmt console?
Currently I can view only the Xen bootup messages if I dont specify the
console=xxx option on the kernel line. I cant see any of
the linux kernel boot up messages. Specifying console=xxx on the kernel
module line doesnt work either.
Has anyone worked with this sort of config before? Is there anything else I
can specify on the kernel/module line so that all
the bootup messages are visible?
Below is my grub menu:
title Red Hat Enterprise Linux Server (2.6.18-164.6.1.el5)
root (hd0,0)
kernel /vmlinuz-2.6.18-164.6.1.el5 ro root=/dev/vg1/root
initrd /initrd-2.6.18-164.6.1.el5.img
title Xen 4.0 - Linux 2.6.31.13 pvops
root (hd0,0)
kernel /xen.gz noreboot loglvl=all guest_loglvl=all iommu=1
module /vmlinuz-2.6.31.13 ro root=/dev/vg1/root loglevel=10
swiotlb=force earlyprintk=xen console=hvc0
module /initrd-2.6.31.13.img
title Xen 4.0 - Linux 2.6.18.8
root (hd0,0)
kernel /xen.gz loglvl=all guest_loglvl=all
module /vmlinuz-2.6.18.8-xen0 ro root=/dev/vg1/root earlyprintk=xen
module /initrd-2.6.18.8-xen0.img
P.S.: Ive tried using the 2.6.18.8 kernel and that seems to show everything
fine on the console.
Thanks,
Adit

You could try adding "nomodeset" parameter, to disable the kernel modesetting (KMS) stuff. Maybe that messes up the console.

The nomodeset parameter didnt work either. One thing I didnt mention was that I could see the Xen bootup messages before and now but cannot see the linux boot up messages. Is there anything I need to enable in the linux config for the console to be visible? There maybe something funky with what the pvops kernel is doing versus the older pv kernel since I can see the messages for the older one. Serial isnt an option since the machine is not physically accessible to me.
