Xen project Mailing List

Hi Emre,

Sorry for the late response.

How could I modprobe xen inside the DomU? I knew to do it in dom0 only.

Thanks.

Hi,

To use xvd* devices, you need to modprobe xen related paravirtual modules (unmodified_drivers) inside your DomU. Then your xvda devices will appear.

In my distribution (Pardus 2008), these drivers are called:xenblk xenfb gntdev xennet xenkbd

To use them, you modprobe them when the system is up, or if you want to use them as your root disk, then you need to create an initramfs with these modules inside.

Best Regards,

Emre

You mean you created /dev/xvda on the dom0? If so, you don't need to
do that, on the other hand it needs to exist inside the domU,
presumably it's a hard-coded device in /dev from the initrd rather
than udev created (it'd be to late), I've never had to check.

I wonder why it mixes its xvd* and sd* devices?
