Dear I need create second bridge xenbr1 for separate traffic between my virtual machine , I following this step but show message that Link veth0 is missing, how I can create veth0 ? When I run script for create xenbr1 ./network-bridge netdev=eth1 bridge=xenbr1 start Shwo this message Link veth0 is missing. This may be because you have reached the limit of the number of interfaces that the

Still trying to make my VMs appear on a subnet of their very own and route traffic to/from them from the Dom0. This network-multinet script sounds ideal for what I want: http://thepenguinpriest.com/linux/scripts/network-multinet.html However, the description of building a routed network says I need to call the script and give it the "virtual ethernet device (vethX)" that lives in

Package: xen-hypervisor-3.0-unstable-1-amd64 Version: 3.0-unstable+hg11292-2 Severity: important My server is a dell 2950 server. Before the dom0 rebooting bug ocurred, xen was well even for hvm domU. By now i have tried xen-hypervisor-3.0-amd64 (3.0.2+hg9697-2) and xen-hypervisor-3.0-unstable-1-amd64 (3.0-unstable+hg11292-2), but both of them are unusable for me. for

Hello, many of our platforms do not have a integrated floppy, some even don''t have a floppy controller. As pxelinux still has a problem with machines without a floppy in combination with some bios versions I need to chainload a different bootstrap loader which works on the floppyless platforms. But I also need to load a BartPE and the other BS loader does not support that. So I tried to

When does vif0.0 get created? Is there some shell magic? I''m trying to figure out how to do a similar peth1/veth1 split for eth1. -- Nicholas Lee http://stateless.geek.nz gpg 8072 4F86 EDCD 4FC1 18EF 5BDD 07B0 9597 6D58 D70C _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hi list. I started with Xen yesterday, but I am facing a bit of a problem. My system had always configure eth0 with 10.0.0.4/8 I am using Xen unstable source (on Debian sid) Now I installed Xen, rebooted the machine, and first the usual network is coming up and then the xend will be started. I''ll end up with this, but I am wondering if this should be the way of things to be

Hi, I'm wondering about the impact of using both dom0 and domU's on a server at the same time. I'm worried about the performance impact of running a Mysql server in a domU and now I'm thinking about moving the Mysql part of a LAMP setup into dom0 and running a few Apache guests as domUs. Since the Apaches will serve mostly from an NFS share they won't have much impact on

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

During my attempts to get the latest bridge networking model working on my system, I often invoked ''network-bridge stop'' with total failure.

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

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! Is it HTB fully compatible with BOND interface? I have this setup (mode= fault tolerance) : BOND0 -> ETH0 + ETH1 BOND1 -> ETH2 + ETH3 ( http://www.kernel.org/pub/linux/kernel/people/marcelo/linux-2.4/Documentation/networking/bonding.txt ) HTB work very well with Class over BOND0. If I add Class for BOND1 it generate balance errors. Also with HTB.init

Using the same pktgen script (i.e with clone=0) I see that a veth-->bridge-->veth configuration gives about 400K PPS forwarding performance where

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

Getting "bnx2i: iSCSI not supported, dev=eth0" for all the NIC adapters on all of my R710's running CentOS 5.5. Here is an sample of the error messages: bonding: Warning: either miimon or arp_interval and arp_ip_target module parameters must be specified, otherwise bonding will not detect link failures! see bonding.txt for details. bonding: bond0: setting mode to active-backup

Hi All, I see an unexpected beahviour from NetworkManager on CentOS 7.1. Using nmcli tool, I create a bond with two slaves as explained in the Red Hat 7.1 Networking guide. I enable slaves and master; bond works as expected. When I restart NetworkManager, it creates a new bond with the same name but not connected to any device. Two bonds with the same name is confusing for my other monitoring

Hi all, Read many posts on the subject. Using 802.3ad. Few problems; Cannot ping some hosts on the network, they are all up. Cannot resolve via DNS which is one of the hosts that I cannot ping, internal nor external DNS hosts. Unplugging the NICS and plugging them back in will then not allow pining if the default d=gateway. When cold booting it somewhat works, some hosts are pingable while
