It''s effectively a point to point link, allowing domain 0 to connect on to the bridge in the same manner that other domains do. (before, packets to domain 0 were short-cutted and came off the

I expect that in most routed configurations people use their own network script rather than using the

Hello, I''m still having problems with my ''upgrade'' to the FC4 xen packages. I have a domain with two virtual network interfaces, in two different subnets. For a domain with a single interface, the new networkd setup script works fine, but it does work (for me) with two interfaces. It used to work fine, and I used to set it up with simply by more or less blindly doing

Hello, I can''t seem to get the network going. I found this message in the log of Domain0: ----------------------------------------------------------------------- Dec 1 15:39:18 zms wait_for_sysfs[4180]: either wait_for_sysfs (udev 039) needs an update to handle the device ''/class/net/br0'' properly (no device symlink) or the sysfs-support of your device''s

Hi John, And an excellent stab that was. I have two network interfaces. eth0 is a 3Com with a Broadcom Corporation NetXtreme BCM5701 Gigabit Ethernet chip, and eth1 is a 3Com 3cSOHO100-TX Hurricane chip. On the gigabit card, I couldn''t test anything, because I could not find out how to disable/enable/check checksum offloading. Using ethtool gives: Operation not supported For the

Hello, Since my last update of xen, I am having problems with bridges and xen. When I want to start a bridge on the dom0 (to run a domU in a different vlan than the default) I run /etc/xen/scripts/network-bridge start netdev=eth0.302 bridge=xen-br302 antispoof=no where eth0.302 is an interface associated with my vlan 302 (it tags with this vlan identifier). The problem I have is that it

Hi, I am using Xen 4.1.1 with Linux 3.0.1 kernel. Previously (Xen 3.4.4 and linux kernel 2.6.18) Xen by default created veth0 <--> vif0.0 pair in dom0. With Xen 4.1.1 these pairs are missing in dom0. Using command ''ip link add type veth'' I can create veth0 and veth1 but vif0.0 is still missing in dom0. (When new domU created I can see vif1.x created) Could you please help

Hello, I''m trying to upgrade to using the "boxed" xen supported on FC4 after having it working fine for a while on a manual installation on FC3. I upgraded the host operating system with the FC4 cdroms, and it went mostly fine (after I turned off SElinux...) Now, when I try to boot one of the provided xen kernels, namely: vmlinuz-2.6.12-1.1447_FC4xen0 I always get the warning

Hi, I''m using RHEL linux 5.1, I can''t add the another NIC to my virtual machine. # /etc/xen/scripts/network-bridge start Link veth0 is missing. This may be because you have reached the limit of the number of interfaces that the loopback driver supports. If the loopback driver is a module, you may raise this limit by passing it as a parameter (nloopbacks=<N>); if the

I''ll end up with this, but I am wondering if this should be the way of things to be

When does vif0.0 get created? Is there some shell magic?

I'm new to the list. hopefully my question is correctly placed here... I'd installed my samba server 3.5.6 on debian squeeze in a openvz container that uses venet. I'd love to keep it that way but I'm not sure if that is ok. Do you use samba server with venet or do I have to change to veth? I already read http://wiki.openvz.org/Differences_between_venet_and_veth and I don't

Hello, I just setup a Xen server and wanted to use bond0 for my network connection. I ended up downloading and addeding the attatched file and making the following change in /etc/xen/xend-config.sxp. I added this line: (network-script 'network-bond netdev=bond0') Would this line be a good one to add to the commented lines and include the network-bond file in the scripts? Just thought

Hi, I'm running OpenStack on CentOS 6.3 to manage lxc instances. And running into series of problem relating libvirt and lxc interaction. For example, libvirt_lxc segfault ( https://bugzilla.redhat.com/show_bug.cgi?id=874549) which has an upstream fix. And another bugs such as fail to start when SELinux disabled. Finally, I decides to adopt libvirt 0.10.2, self compiled from
