[ovs-discuss] OpenVswitch with KVM virtual machines
I am running NOX controller with a python script that prints out the
destination mac and the source mac for each packet arriving at the now
controller and then floods it out. So here's what happening:
With em1 connected, all the packets that arrive at em1 are coming to the
controller and printing out the details. However, without em1 connected to

[Fwd: Re: [Fwd: Re: Still ATAPICAM Lockup/Slowdown]]
Thomas,
Have spoken to Soren, from my bootlog he believes that the problem is in
atapicam causing the system to lock up. He is happy to answer some
questions but doesnt have time to delve into atapicam himself.
Did you author atapicam, I have seen your name on the sourcecode, can
you help me further? Whats next?
Thanks Adam.

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

Please help....normalization by the median of some control genes
Can someone show me some code to do normalization by the median of some control genes for the example below?
Many Many Thanks in advance
This strategy selects a subset of genes (called ?control genes?) and makes the median of their data distribution similar across arrays.
??? ??? id1??? id2??? id3
control1??? 0.8??? 0.7??? 0.6
control2??? 0.6??? 0.2??? 0.4
probe1??? ??? 0.3??? 0.2??? 0.5

about the script /etc/qemu-ifup with nmcli command
Hi,
I have tried the qemu-ifup script as below with nmcli command as brctl is
deprecated on rhel8, but the guest network can not work.
I think the script needs update. Could you please help to have a look?
Thank you in advance.
1. prepare a linux bridge on the host named br0;
2. prepare the qemu-ifup script as below:
# cat /etc/qemu-ifup
#!/bin/bash
# A br0 bridge should be already set up.

KVM - Network bridge issue - lots of overruns
Hi everybody
I've a very big network problem with some server running CentOS with
KVM and some linux-like VMs on the top of it.
The vm's network is bridged with a physical dedicate NIC (an Intel
PRO/1000) with 2.4.14-NAPI driver (but the problem persists with various
versions of the driver) and the CentOS version is 6.4 (same problem with
a 5.7 sever) with all the last updates.

Need info on vnet mapping to guests
Hello:
I have a host running two KVM guests. The guests
use br0 and each has a static IP address.
I am trying to figure out if there is a way to
use snmpd on the host to measure the traffic
usage of the guests. I do not want to require
anything running on the guests since I do not
control them.
Looking at netstat -in on the host, I see this

Remove Virtual bridge and DNSMASQ
I am running KVM virtualization with libvirtd (libvirt) 0.10.2 in bridged
network mode, however I still have the default virtual network
bridge/interfaces and dnsmasq on the host. What I am trying to understand
is whether or not dnsmasq and the virtual network (*virbr0, Vnet0 and Vnet1*)
still play any role. If not, can I remove them?
On most virtual hosts I see they are left around even when a

gPXE fails automatically, succeeds with manual autoboot
Hi Folks,
I'm trying to auto-create a VM using a kickstart server and gPXE with
