Hi,

When running domUs with pygrub, I get errors:

....
xen be core: xen be core: can't open gnttab device
can't open gnttab device
xen be core: xen be core: can't open gnttab device
can't open gnttab device
xen be core: xen be core: can't open gnttab device
.....

domUs start, but these errors continue on dom0


Configuration:

dom0:
Ubuntu 8.10

xen_major              : 4
xen_minor              : 0
xen_extra              : .1-rc3

# udevinfo --version
124

# ls /dev/xen
blktap0  evtchn  pci_iomul

latest linux-2.6.18-xen

domUs:
Ubuntu 10.04 and Centos 5 64bit
latest linux-2.6.18-xen


I failed to find any CONFIG options for GNT in kernel configs.
