[Fedora-xen] interface tun0 does not exist!
Hello, I can not setup any guest''s becose of missing interfaces. /var/log/xend-debug.log: Link veth0 is missing. This may be because you have reached the limit of the number of interfaces that the loopback driver supports. If the loopback driver is a module, you may raise this limit by passing it as a parameter (nloopbacks=<N>); if the driver is compiled statically into the kernel, then you may set the parameter using loopback.nloopbacks=<N> on the domain 0 kernel command line. interface tun0 does not exist! interface tun0 does not exist! interface tun0 does not exist! interface tun0 does not exist!>From dmesg:bnx2: eth0 NIC Link is Up, 1000 Mbps full duplex bnx2: eth1 NIC Link is Up, 1000 Mbps full duplex bnx2: eth2 NIC Link is Up, 1000 Mbps full duplex bnx2: eth3 NIC Link is Up, 1000 Mbps full duplex /etc/grub.conf: # grub.conf generated by anaconda # # Note that you do not have to rerun grub after making changes to this file # NOTICE: You have a /boot partition.

AW: [Fedora-xen] interface tun0 does not exist! -> HALF SOLVED
Hello again, I found the problem..stubid.. I have installed kernel-xen With kernel-xen0 the interface are there. Becose then I can use only 4Gb memory. What can I to now do use 16G of memory ?
