Re: [Xci-devel] dom0 can't find the LVM volumes

I seem to have installed XCI correctly, as GRUB 2 starts up correctly (and
is thus able to read the LVM volumes). When choosing "XenClient - Debug", I
get a black screen and the following serial output from the kernel (only
last few lines):

The LVM is found immediately by a Debian live CD, but XenClient's kernel
doesn't seem to find it... What could be the problem here?
Hi,
It's probably because we don't have disk driver for VmWare in our dom0
kernel config.
Jean
Yes I think you're right, as the kernel doesn't show any "sd: "
messages. In the dom0 /lib/modules folder, there are neither
the scsi nor the sd module.
Could you please give me a hint on how to change the dom0 kernel
configuration (menuconfig) and rebuild it?
