Re: [Xen-users] FW: Xen 3.3.2 with under Centos

Rob--are you sure you did the mkinitrd right and have the /etc/modprobe.conf set correctly to see the Xen devices? that
is a common cause of this error.

No one seen this before? I just don't understand why my normal kernel
compile works fine but the Xen variant fails to find a boot device at
all. The most significant error I can see is Volume group "VolGroup00"
not found.

Does anyone know why this error might occur, I have the various LVM and
other Raid helper type options enabled in the Linux kernel and a plain
build of the same kernel works.

Thanks in advance,

Subject: Xen 3.3.2 with under Centos

Hi Everyone,

I'm trying to do my first Xen Kernel compile under Centos 5.2 using Xen
3.4.1 and kernel, I'm using bits of instructions from a Fedora
guide and bits from other places:

My plain compile works fine with the exception of a couple of
SELinux definition complaints. My Xen kernel fails though, initial boots
starts but I get a cannot find root file system error early in the boot.
I think I have managed to sort the various dependencies because the
compile does finish (Seems Xen-tools has a few dependencies). Any ideas
what might cause this error? (The test system is nothing exotic, it's an
Intel P4 with I875 Intel chipset)

Do I need to set Xen Compatibility code to nothing or 3.3X in the kernel
Menu-config? Anyone know why Infiniband options can be enabled in but seem to be greyed out in
