Re: [Xen-devel] Xen Dom U kernel

[kishore kumar <bodkekumar@xxxxxxxxx>]

I am using RHEL5.

 

and I have below too in my .config.

 

CONFIG_SYSFS_DEPRECATED=y
CONFIG_SYSFS_DEPRECATED_V2=y

 

My /etc/modprobe.conf has the following

 

alias scsi_hostadapter ahci

alias eth2 ixgbe

alias eth3 ixgbe

 

Do I need to add the below lines in /etc/modprobe.conf ??

from http://wiki.xensource.com/xenwiki/2.6.18-to-2.6.31-and-higher link?

 

# RHEL -> FC11 quick upgrade path.
grep -q xenfs /etc/fstab || echo "xenfs                   /proc/xen               xenfs   defaults        0 0" >> /etc/fstab
if grep -q ata_piix /etc/modprobe.conf ; then
        NR=`cat /etc/modprobe.conf | grep scsi | wc -l | sed s/[[:space:]]*//`
        grep -q pata_oldpiix /etc/modprobe.conf || echo "alias scsi_hostadapter$NR pata_oldpiix" >> /etc/modprobe.conf
fi
grep -q hvc /etc/inittab || echo "co:2345:respawn:/sbin/agetty hvc0 9600 vt100-nav" >> /etc/inittab
grep -q hvc0 /etc/securetty || echo "hvc0" >> /etc/securetty

Could you please let me know what exactly needs to be done?  I could not get much out of it?

Thank You.

Hmm, Are you using a RHEL5/CentOS based userspace to build the initrd image?

If you are please take a look at this:
