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. I want to keep the

Xen 3.3 bridged-networking
Hi I don''t quite understand the new xen networking. We use network-bridge! Everything works fine except that an iptables firewall on dom0 blocks all my domU. In my firewall settings i use eth0. I figured out that eth0 is the bridge but where is the interface for dom0? I want my firewall setting to only apply to dom0 interface! Since there is not anything like vif0.0 i don''t know

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

ping out of domU OK ping in to domU not OK
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 Dom0 network fails to start at boot
I have a server running Centos 5.2 as a Xen host. A problem that's shown up recently is that at boot, the dom0 interface eth0 doesn't come up properly, with the result that the host is only accessible via remote console. If I execute 'service network restart', eth0 comes up normally, with an IP address and the correct routing. Three guests have been created via virt-manager

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

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

Cannot ping DomU from Dom0 / cannot ping same site from two DomUs at the same time
Hello! I have two problems. One is, that I cannot ping a DomU from Dom0 (or any other host in my local network) and the second one is, that I cannot ping the same site (eg. www.suse.com) from two DomU''s at the same time. I have a fresh installation of openSuse 11.0 with Kernel 2.6.25.20-0.1-xen and my box has two physical ethernet cards. As far as I have investigated, eth0 is the one

Networking problems with fresh install
I just did a fresh install of centos 5.0 from cd, followed by yum update which installed 399 packages. No failures or errors that I can see. I have three nics in the box, but am only setting up one at the moment. The box can ping others in my network, but if I try ssh, telnet, ftp, etc I get this: [root at cm network-scripts]# ftp watchdog ftp: connect: No route to host ftp> [root at cm
