Re: Xen 4.5 & modules-load fialed .

I think Xen modules got renamed. Taking the "gntdev" module as an example, please try running the following commands:

find /lib/modules -name '*gntdev*'

and

grep '^BACKEND_MODULES=' /etc/init.d/xencommons

I'm running Xen 4.5.0-3 on kernel 3.18.6-1 (yes, I know it's an old one, due to an unrelated problem I've been having) and I get these results:

[ashley@hoom ~]$ find /lib/modules -name '*gntdev*'
/lib/modules/3.18.6-1-ARCH/kernel/drivers/xen/xen-gntdev.ko.gz
[ashley@hoom ~]$ grep '^BACKEND_MODULES=' /etc/init.d/xencommons
BACKEND_MODULES="xen-evtchn xen-gntdev xen-gntalloc xen-blkback xen-netback xen-pciback evtchn gntdev netbk blkbk xen-scsibk usbbk pciback xen-acpi-processor blktap2 blktap"

If I remember correctly, you have to edit /etc/init.d/xencommons so it names the modules correctly.
