Hi

I'm trying to upgrade my environment from xen 3.4.0 to xen 4.0 via
rpm that fits in our product. I installed new tools and xen, and it
looks like I am missing a step.

In 4.0 qemu DEVOPS_FLAG_NEED_GNTDEV was added to xen_console_ops. This
results in xc_gnttab_open() being called which calls
xc_find_device_number() to get device nums for /dev/xen/gntdev so it can
mknod. xc_find_device_number() is failing because there is no entry in
the the sysfs.

So, can someone please advise how the entry is created in the sysfs? The
exact path it's looking: /sys/class/misc/gntdev/dev


thanks,
Mukesh
