vif-antispoof
Hi folks, I started testing the antispoof feature of xen stable (2.0.7). I am stuck with it. I have setup a standard bridged environment. I understood it like this: in domU config I set up the virtual NIC like vif = [ ''mac=ae:00:00:78:78:78, ip=192.168.0.100'' ] Then I configure /etc/network/interface of this domU to show the same IP address for eth0. After restarting

vif-common.sh and iptables
Hey everyone, I have a question about vif-common.sh. I run multiple bridges attached on dummy interfaces, which allow me to put guests in seperate subnets (routed through the dom0). As you might expect I already have quite extensive iptables scripts to accomidate this kind of routing. I was just hoping someone on this list can confirm, that I understand what the iptables lines in vif-common.sh

Bug#698841: xen-utils-common: HVM networking for ioemu devices is blocked when antispoof is on
Package: xen-utils-common Version: 4.1.3-8 Severity: important When antispoof is set to 'on', the vif-common script does not create an ALLOW firewall rule for the emulated vif devices. This means that HVM nodes, unless a Xen PV driver is installed and running, cannot access the external network. The vif-common script creates an ACCEPT entry for the normal vif device (e.g. vif4.0) but not

Dom-U config: whats the role of vif - IP
Hello, in the example configuration-files I always read, that I''ve to add an IP-Adress if I don''t have a DHCPd running. I''m running in bridge-mode. For example: vif = [''ip=192.168.5.99''] But I don''t want to configure the IP-Adress in an config-file on Dom-0; the Admin of the Dom-U should do that with Dom-U''s ifconfig (or

how to get rhel3-ish distro run as domu with xen3
hello! i think i have an very common problem. i want to run a distro based on a 2.4 kernel (Scientific Linux 3/Centos 3/RHEL 3) in xen3 as domu. the dom0 is a 2.6 based and works fine. so i think the way to go is to "simply" use an 2.6 kernel. but now i see there are several things which don''t work for example module-init-tools are missing and i expect problems with the glibc.

In M08.raw/boot I configured grub/menu.lst:

[Xense-devel] [RFC][PATCH][ACM] enforcing ACM policy on network traffic between virtual network interfaces
This patch adds an ACM hook into the network scripts (/etc/xen/scripts). It adds iptables rules that enforce mandatory access control on network packets exchanged between virtual interfaces. If ACM is active, this patch sets the default FORWARD policy in Dom0 to DROP and adds iptables ACCEPT rules between vifs that belong to domains that are permitted to share (determined by using the
