vif0.0: received packet with own address as source address
Hi all, Has anyone seen this before? I''m running a CentOS 5.3 with xen 3.0 and the server has been running fine for a long time. In fact, it was up for 186 days before I had to reboot after the "network died", and I couldn''t fix it. The server has multiple domU''s on it, which all still works when the host node (dom0)''s network dies with these

Arp Flip Flops make machine inaccessible.
CentOS 5.5 Xen "standard" Xen Installation. I have two nics. I just put the second one to DHCP and modified the ifcfg-et01 and so far I am holding, but I am not confident. Prior they were sequential IP Addrs on same subnet. arpwatch has indicated flip flips. I can find no rhyme or reason to predict them. I know I missed I must have missed a step somewhere.

Strange dom0 networking error with Debian "Etch" amd64
Hi, We''re trying to run Xen on a Debian "Etch" base system (kernel 2.6.18-6-xen-amd64), but have come across a strange networking error whenever bridging (vif-bridge/network-bridge) is in operation. The symptom is that the dom0 base system loses all network connectivity to the outside world while the two guest instances function perfectly well. As far as we can tell, we

Centos and xen network bridge issue
Hi All, We have a single Centos 5.11 server running a xen hypervisor that went down hard after an extended power outage this weekend. I'm mostly familiar for KVM as that is the majority of what our guests run under and have tried getting up to speed on xen bridging to no avail. The problem is that after the xen server spun back up, the previously defined xen bridges were lost. I've

I''ve setup Xen 3.0.2-2 (binary install) on Ubuntu 6.06, got my domUs up and running, got them connected to the Internet but I can''t even ping to any of these VMs. Now I''m not linux/xen genious but could the problem be that xen-br0 doesn''t have an IPv4 address? (it''s got an IPv6 address) Since I don''t use IPv6 on my network this seems a

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: eth0 Link encap:Ethernet

NIC bonding - missing eth0?
I have nic bonding (mode=802.3ad) setup on 2 servers, both running Centos 5.5 In the "Active Aggregator Info", on one reports 4 ports - which is correct - but the other only reports 3 ports. It's always eth0 that shows a different aggregator ID. Changing the cables around so it hits a different port on the switch makes no difference. The switch is correctly configured for the port
