similar to: Changing MAC address of Xen domU after live migration?

Hello everybody, I'm developing a source code transformation system for real-time systems currently, i.e. I want to map the application (a set of event handlers) to a run-time or operating system semi-automatically (if anybody is interested in the background - see below, of course, comments are welcome there, too ;-)). Therefore, I have to be able to express dependencies between different

orabug: 14470382 When Dom0''s network environment change, for example the issue, DomU should send send gratuitous ARP initially to notify how to reach it. To fix the bug, we should modify backend and frontend at the same time. For fixing frontend, i filer the new bug 16182568. The review only to backend. For fixing the backend, I have 4 patch for review. Thanks, Jason

Hi! I have some problems with an bridge between wlan0 and eth0 device... It works and I can from both sides ping the router with the bridge device but I cant ping the devices from other net so I cant ping wlan devs from eth net and other way around the wlan card is an atmel usbw11 from linksys and eth is a intel e100 10/100mbit nic I have configured the bridge according to the how to and

I''ve implemented code to send out bogus gratuitous ARP packet from vna in order to fix CR 6701114.

But, the

hi list members, my goal is to make one of my DomU''s act as a wireless accesspoint... So, i need it to have access to the pcmcia wlan card attached to dom0. But how ? when i give the pci=[] option to the domU config file its shows up with lspci but i cant use it... (on debian with module-assistent get rt2x00 in de DomU) Is it possible or would it be better to use a more direct interface

Hello all, I had setup shorewall before succesfully with a normal LAN to internet connection. Now I''m connected to the internet via VPN and I got problems with configuring Shorewall. Any help is appreciated. This is my setup: - Gentoo Linux laptop (kernel gentoo-dev-sources-2.6.8.1) with Shorewall 2.0.4 (setup for Standalone one interface) and iptables 1.2.11 - VPN client is

Hi, I would like to know if somebody can point me out how to configure several DomUs in a private LAN (for example 192.168.100.0/24) and one DomU with two interfaces (one - 192.168.100.0/24 and two - internet). So far I have enabled in xend-config.sxp: (network-script network-route) (vif-script vif-route) My config files have: /mnt/VM/1.cfg:vif = [''ip=192.168.1.3'']

I''ve had a shorewall firewall protecting my home network for almost 3 years now which is currently on a RedHat 7.3 box and I''m running version 1.4.7 I''m replacing this box with a newer one and have set it up with Gentoo linux and the 2.6.9-r9 kernel and installed Gentoo''s distro of shorewall which is version 2.0.7. I have also compiled the needed netfilter

Hi all, I have plan to replace my Centos5.7 VM with newer version. The VM works as our network gateway. I want to ask from your experience, will it be a bad decision? My concern is that since the Mac Address of the gateway will change, will it disrupt the network? How fast the Switches can recognize the new mac? Any other pitfall? Thanks Fajar.

So, I'm setting up my first bridge, and I'm running into an interesting issue. I have a 4 port NIC (formerly 4 seperate /29 and /28 LANs) and an onboard NIC (to my ISP). I've setup the bridge using the script included at the bottom of this email (modified from Gentoo for Aurora). When the WET11 (the WET11 is a simple ethernet to wireless bridge) is unplugged, the bridge works

After a guest is live migrated, the xen-netfront driver emits a gratuitous ARP message, so that networking hardware on the target host's subnet can take notice, and public routing to the guest is re-established. However, if the packet appears on the backend interface before the backend is added to the target host's bridge, the packet is lost, and the migrated guest's peers become
