kvm with bridged network
...reinstall these guest very often). unfortunately it''s not
possible to use routed network with pxe boot. so we _need_ bridged setup
kvm with config as described in:
http://www.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6-Beta/html/Virtualization/sect-Virtualization-Network_Configuration-Bridged_networking_with_libvirt.html
is it possible with shorewall?
eg how can i add this rules to shorewall:
iptables -I FORWARD -m physdev --physdev-is-bridged -j ACCEPT
or is it enough to add bridge to the interfaces file?
thanks in advance.
regards.

Centos 6.2 / KVM troubles with network
...addres for both eth0 and br0 interfaces. ifconfig
shows that eth0 has no IP address, br0 has IP address. So, I test this
case.
- I use Red Hat documentation:
http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5/html-single/Virtualization/index.html#sect-Virtualization-Network_Configuration-Bridged_networking_with_libvirt)
- On virtual machine I created bridge connection with br0 interface on
CentOS 6.2.
- All machines have all connections.
- All firewalls and SELinux are closed.
NFS server on CentOS 6.2 (hardware machine) doesn't serve exported file
system.
The questions:
1. Is it proper that eth0 has no IP a...

Network configuration on KVMs
In the Redhat EL6 virtualization guide (
http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Virtualization/sect-Virtualization-Network_Configuration-Bridged_networking_with_libvirt.html
) I read this:
#
Configure iptables
Configure iptables to allow all traffic to be forwarded
across the bridge.
# iptables -I FORWARD -m physdev --physdev-is-bridged -j
ACCEPT
# service iptables save
# service iptables restart
Disable iptables on bridges
Alternatively, prevent bridged traff...

problem with bridged network for a kvm guest
I'm having trouble with the bridged network setup. I'm new to kvm, but I
got a window xp sp2 guest set up without trouble a few days ago. I followed
the instructions in the RH virtualization guide, and all was fine until I
had to reboot the host machine a few days later.
Then, I lost networking altogether on the host machine. I lost track of all
the things I tried, but finally got

Centos 6 - Networking: Some Queries -- GURUS HELP PL
With NM_Controlled=No in the ifcfg file, NM applet shows "Not Managed", so
the ifcfg file is being read. What is the extent of interaction of
NetworkManager with ifcfg files is unknown....very little information on
the net. Seems Network Manager is still mostly unplublished compared to
other utilities. Any pointers to literature on this or macro architecture
of NM would be appreciated,

KVM host question about host firewall
Hello All:
I'll ask this in the virt list later if this is not the appropriate forum...
Yesterday I was troubleshooting an issue with a KVM host. I was
unable to access the DNS service on a KVM virtual machine. After
verifying that the vm allowed through the DNS ports (53 on UDP/TCP)
and still being unable to access, I was able to connect immediately
after allowing those ports on the

configure network bridge listing bridged intefaces
Hi all,
Having a 4 NIC server, I want to bridge eth2 and eth3, with a bridge
named br0.
Searching the web I only found about creating a file
/etc/sysconfig/network-scripts/ifcfg-br0, but did not find where to
explicitely list what ports will be bridged.
Where is it configured?
Thank you.

my notes on bond, bridge, network, kvm, host and virtual so far
I put this page together just so I won't spam the board anymore begging
for help..lol
http://bobhoffman.com/vmissue.html
This shows a working effort of bonded eths, bridged into a vm, and a few
other things.
The only missing thing is something on the host that ends up putting the
VM internet
connection into some kind of limbo.
Whether it is hardware related, bug related, libvirt nat

Centos and Bridging
Hello,
Presently I am running CentOS release 5.5 (Final). I am looking to setup

but I cannot figure out where I am going wrong and would be thankful if
someone could point me in the right direction.
