Second Xen NIC not being recognized?
I've got a Xen domU running Centos 5.2 (dom0 is also Centos 5.2) with two
NICs configured. Both NICs show up in the Xen hardware details display.
Looking at dmesg output from rebooting the domU, I see both eth0 and eth1
appearing there. But network configuration only knows about eth0, the one
that was installed originally (eth1 was added later). There's options to
create another NIC in

[Bridge] One NIC not bridging?
Hello,
I'm having a problem getting two (working) NICs enslaved to a bridge to both
work in the bridge.
The setup is just for testing and looks like this:
(NETWORK)-------|bridge|---------|test PC|
I'm building a bridge from an old Dell Optiplex GX1 desktop. Using
kernel-2.6.9-gentoo-r4, with bridging and ebtables compiled into the kernel;
the two PCI NICs are Intel, and the e100

VM nic not taking IP address
I have a DomU as a firewall (using the Dom0 kernel). I hid the three
nics from Dom0 and assigned them to the firewall VM. The firewall VM
sees the three nics no problem. Eth0 comes up and grabs an IP
automatically from my DHCP server, however eth1 and eth2 are configured
with static IPs but they do not come up with an IP:
Here is my ''ifconfig'':

2nd NIC troubles
Hi All,
I have 2 NICS in this system. CentOS 6.4
eth0 is the virtual IP from PFSense mapping connected to the router, works
fine.
eth1 is a second NIC that I have assigned a private IP to and connected it
to a switch on the private network. I have many other private devices, so I
know this setup works.
When I connect the cable to the switch and bring up eth1 the system
basically stops taking

Can't assign the 2nd MAC address to the VM
to all who read this message,
I can't assign the second MAC to the second NIC for a VM. If only use 1 NIC, assigning MAC works. But not for 2 NICs or more. Do anyone has any ideas?
I have installed KVM on Ubuntu 11.10 64bit on my laptop. Also created the bridge on the host, and also taps.
I created a RHEL 6.1 64bit VM on this environment and run:

error enable msi for guest 4 status fffffff0 (link of nic exposed directly to domU using pciback stays down)
Hi xen-devel,
I have been trying to pcihide a NIC from dom0 and directly claim it on domU.
The dom0 had come up with the bnx2 driver claiming the nic card, but after
that i did an unbind and bound the pciback driver with this interface.
lspci on domU shows the only pci device and it is claimed by the bnx2
driver.However the link of the interface as shown by ethtool continues to be
down.

udev rename NIC failed
Hi,
Sometimes, I found one of my Mellanox NIC renamed to rename6, instead
of eth1. The right names of NICs in my system should be:
eth0 Mellanox NIC
eth1 Mellanox NIC
eth2 Intel NIC
eth3 Intel NIC
eth4 Intel NIC
eth5 Intel NIC
eth0 and eth1 will combined as bond1 with mode 4. However, the current
names are:

[BRIDGE]A basic question: what's the relationship of the Rx/Tx packets count between the bridge and its enslaved NIC.
I have a bridge br0, it enslaves two NICs: eth0 and eth1.
By using "cat /proc/net/dev ", i can see the Rx/Tx packets and bytes
through each interface. just like this:
[* time tick 1 *]
Inter-| Receive | Transmit
face |bytes packets errs drop fifo frame compressed
multicast|bytes packets errs drop fifo colls carrier compressed

work fine in the non-xen kernel.
