Re: [Fedora-xen] Lost peth0, not sure how to get it back...

[Mark A Heilpern]

I had a similar problem, though not exact. Perhaps my work-around will work for you also.

In my case, peth0 (which I needed) would not get created, but peth1 (which was useless to
me) was created. I tried swapping IP addresses, name designations, etc, but the pethX
device created was always for the wrong interface.

I modified the eth1 device configuration to make it not come up on boot, and peth0 was
being created. I also modified my rc.local script to bring up eth1, which worked fine with
regards to xen since xen had already done its thing.

It's an ugly hack, but it did the trick.

back...I have been playing with xen and domU and things were working fine, I've added
a second nic to my setup and somehow when configuring it I have lost peth0, so none of my
domains are working.  When I run the xen network-bridge script I get the following:

[root@localhost scripts]# ./network-bridge start
net.bridge.bridge-nf-call-arptables = 0
net.bridge.bridge-nf-call-ip6tables = 0
net.bridge.bridge-nf-call-iptables = 0
SIOCSIFNAME: Device or resource busy


Here is the output of my ifconfig -a (note no peth0):
