[Xen-users] Many vifX.Y and vethX

[Ognyan Kulev <ogi@xxxxxxxxxxxxxxxx>]

Hi,

I'm using Xen 3.0-testing Debian Sarge i386 packages from 
<http://packages.debianbase.de/>.  There are many (unused?) vethX and 
vifX.Y interfaces in both dom0 and domU (I attached "ip a" output).  Is 
this normal?
Regards,
ogi
