so close! just an iptables rule away.....?
Hi,
I''ve been making leaps and strides with Xen on FC4. It has been easy to get
installed and to start our first virtual host.
I''ve got one outstanding issue with iptables that is preventing me
progressing further.
This is a colo''d server. It has s single NIC with public IPs.
The bridge is set to come up binding vif* <> xen-br0 <> eth1.
I can start a

KVM live migration i/o error
Hi.
I have three Ubuntu Server 14.04 trusty with KVM. Two of
them are HP servers and one is Dell. Both brands run fine
the KVM virtual servers, and I can do live migration between
the HPs. But I get I/O errors in the vda when I migrate to
or from the Dell server.
I have shared storage with NFS, mounted the same way in all
of them:

FreeBSD, NUT OmniVS1500
Howdy,
I had this working with lots of help for a developer before (Charles Lepple),
but after upgrading to a somewhat more current version of FreeBSD the
patched-up version stopped working. Seeing as this was more than a few years
ago, I thought I'd give a new libusb and NUT a try to see if it might work out
of the box. So far, no luck.
Some info:
FreeBSD 6.3
libusb 0.1.12
NUT 2.4.1

[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

TC on multiple nics
Happy New Year.
Finally got my fw and tc rules down pat for the bridge, now interested
in introducing a third nic to have nat on the box as well. Does anyone
have a idea of a good place to start reading up on the subject, mainly
interested in how to setup the flow direction to start with as to get a
overall understanding of the flow, found that help best.

need to load uhci_hcd with acpi=off
Dear all,
I have running a DOM-0 on debian squeeze with the most recent kernel:
Linux 2.6.32-5-xen-amd64 #1 SMP
On 30% of all reboots the system hangs and only a reset helps.
acpi=off as an additional kernel parameter solves this problem, but
the usb keyboard of the installed ip-kvm is not found then.
with acpi=off Ican find a lot stuff like:

2 NICS - local services not shaping correctly
Hi
Having a problem trying to figure out how to shape local services
running on the debian box (asterisk, squid etc) as currently the voice
only seems to be getting shaped one way when making external calls. For
example I have the rules below (these are the matching rules only not
the actual policy rules):
#Create Chain for local traffic (outbound)
/sbin/iptables -t mangle -A match-all -m

Mail server on DMZ
Hello,
I have this problem: when my mail server on the DMZ starts a connection to
the internet it''s ip (213.58.230.26) is "masqueraded" with the firewall ip
(213.58.230.50). I wouldn''t mind but there is a one customer who rejects the
connection because it makes reverse dns and finds no dns entry for the
firewall ip.
How can i correct this?
Thanks,
MSantos

Bug#571634: bridge loosing connection
Hi,
I'm not sure but I think I suffer under the same problem with a bit
different setup with squeeze testing and xen 4.0rc5.
In fact I'm using bridges in the dom0 and the connections to the domU
get lost sporadically.
In don't see where's a solution to the problem... Is it now a bug? When
it's an iptables bug, where's the corresponding bug in the iptables

Htb queueing problem
A note to confirm that "-m physdev --physdev-is-bridged" in the iptables
command does enable iptables to work in a bridged environment. I was
fighting the same problem and this indeed solved it.
Below is my test script running on a two NIC Debian 3.1 266MHz bridge.
Before adding the physdev flag, only the "tc filter" commands worked but

Bug#571634: xen-utils-common: using --physdev-out in the OUTPUT, FORWARD and POSTROUTING
I recently encountered this in the logs of a new Debian Xen Dom0, and
having now spent the better part of a day researching and testing, I've
come to the conclusion that this is not a bug in xen-utils-common or
even iptables; it's merely the consequence of structural changes to the
core netfilter code starting in the 2.6.20 kernel.
This is rather long, but the issue is complicated. Please

Xen bridge + iptables FORWARD
Hi all,
I have Xen 3.2 newly installed on Lenny with network bridging configured.
When I built my first VM, I found it couldn''t connect to the Internet. This
turned out to be because my dom0''s iptables was configured to DROP all
packets on the FORWARD chain (when I removed that, it started working).
The "Xen Networking" page on the wiki describes this exact situation

Accepting RELATED, ESTABLISHED (TCP) connections into VM using Network Filters
Hi,
Over the past few days I've been trying to get a prototype working of a stateful firewall for a Virtual Machine using Libvirt's network filters.
My goal is to replace the current custom Python/Java code in the Apache CloudStack [0] project by Network Filters of Libvirt.
Both IPv4 and IPv6 should work, but I started off with IPv4 and I have issues with accepting back
