vif''s disappear after dom1 reboot
Today I found I can not ping some of my domU''s. I logged in to dom0, did a "xm list", all domU are there. Then I did a "ifconfig" and surprised to find some of vif''s disappeared! Like for example. "xm list" show dom13 is alive, but "brctl show" shows no vif13.0. If I "xm console 13", there''s some message: WARNING:

Bizarre Networking
Hi, I''ve bit the bullet and gone with Xen, but I get some odd networking. Basically, this was the original idea. eth0 external eth1 internal create bridge br0 for eth0 create bridge br1 for eth1 Strip IP addresses for eth0 and eth1 and assign to br0 and br1 respectively. Worked great in a non-xen kernel under Fedora 8 in KVM/Qemu. Booting into Xen, my eth1 becomes eth2, I also get

Not sure if my bridge is the problem or my firewall
I''m running Xen and created a virtual os called Domain-1. So now I have two systems, Domain-0(dom0) and Domain-1(dom1), both running fedora 8. I only have 1 ethernet device eth0. However, for some reason, my internet doesn''t work in Domain-1. My output for route -n on Domain-0 is: Kernel IP routing table Destination Gateway Genmask Flags Metric Ref

RE: veth0 is from netback and vifu.0 is fromthebridge-utils?

You can have multiple vethX interfaces on recent builds -- see netback/loopback.c. I think the current default is a rather miserly 1 (and should be increased), but can be set on the command line.

Promiscuous mode
Hi Everyone, In order to prevent DomU from entering promiscuous mode, is it just a matter of adding these 2 rules when the vif is created? # Accept packets leaving the bridge going to the domU only if # the destination IP for that packet matches an authorized IPv4 # address for that domU. iptables -A FORWARD -m physdev --physdev-out vif1.0 \ --destination 216.146.46.43 -j ACCEPT

vif-bridge
All works fine on my virtual hosts, except the network. The internal interface is created (have an ip address), the external bridge is ok, with the external vif1.0 for the virtual host, but `ping virtual_host_address` dont work. Ok, I try to put on vif1.0 an ip address. When I do an `ifconfig vif1.0 127.1.2.3` the network works fine, `ping virtual_host_address` works and all machines from my

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.

Vif only accepts connex after talking out of domain.
My domains dont see any traffic until you try to connect out from within the domain. Tried this several times and it was consistent. I have no firewall either. running each domain on different cpu probably doesn''t help, although Im no network expert. Here is some info. ================ [root@a root]# xm info system : Linux host : a.b.com release

HVM vif without bridge
Hello, When using xen without a bridge but NAT or routing, HVM domains can''t boot, and qemu-dm-n.log contains: config qemu network with xen bridge for tap0 xenbr0 bridge xenbr0 does not exist! That''s because the qemu-ifup script always tries to add the vif to a default-named xenbr0 bridge. On the contrary, PV domains just work fine with the same configuration file except HVM
