Problems setting up bridge
Hi,
I have a fc14 box with two interfaces that I'm having some difficulty
setting up a bridge properly. I have a few kvm guests set up and
running, but I've switched from using NetworkManager to using standard
networking with a bridge. I've modified the ifcfg-eth0 and created
ifcfg-br0 as per the standard documentation, but I think I'm having
routing problems. This is what the

SSH ping etc not working between dom0 and domU''s
Hi!
I have a problem with my new Xen setup. I have installed Debian etch
with netinstall and I''m using 2.6.18-6-xen-amd64 kernel in my dom0 and
3.0.3-0-4 version xen hypervisor. I''m using four network cards on my
system and using three of them as xen bridges and dom0 is using the
fourth one only for it''s own. So basicly both of my virtual servers use

Network inoperable with QEMU arm example image
I am running Fedora 16 64bit and installed libvirt. I have the VM
running with arm emulation with this one issue I can't figure out. I
used Virtual Machine Manager to manage the VM and can access its console
there. The Ethernet appears to be eth1 and the guest can set an IP on
it etc. However, I cannot see any traffic from the Host when dumping
any of the interfaces. I've tried

Xen Networking Issue with CentOS 5.1
Hi,
I tried this post on the Xen list first with no answer. I have 4 machines and 3 of which (all different) have no network access when booted into Xen. I tried using Fedora Core 8 and it produced the same results. Is it normal for the virbr0 interface to take an arbitrary IP? How does it decide what to use? An ifconfig when booted into Xen shows the following:

TEQL and Subnet problem
TEQL and Subnet problem
I have a network topology shown below, and I am trying to use TEQL. My
problem is: When I ping to P3.teql0 from P2 ("[P2]# ping 16.119.144.66"),
the traffic can never go from P2.eth1, and all traffic only goes to
P1.eth0. What P2.eth1 (16.119.144.33) did is broadcasting an ARP asking

Slow network

Any suggestion on how to track down the problem with speed.
I have checked the packets with wireshark, no
