I'm running a Mumble server (Murmur) on a Debian Wheezy Beta 4 KVM guest which runs on a Debian Wheezy Beta 4 KVM hypervisor. The guest machines are attached to a bridge device on the hypervisor system through Virtio network interfaces. The Hypervisor is attached to a 100Mbit/s uplink and does IP-routing between the guest machines and the remaining Internet.
I have 2 virtual machines that can not ping/access one another.
I am setting up a exchange server, and a domain controller as guest machines in virtualbox. All machines including the host are running windows server Datacenter 2008 R2. I have my networking set to "bridged", and static ip's set in both the virtual machines, and host (but not on the network adapters).
I am setting up a network with machines that need to be accessible from the internet. I'm planning on putting these in a DMZ. Some of the machines in the DMZ need access to machines on the private network and machines on the private network need access to machines in the DMZ.
I have read that the most secure implementation is one with two firewalls.
I'm looking for a way (kernel patches, configuration, etc) to bond multiple network interfaces together ... but for limited purposes.
Here's the setup. Machines A, B, C, and D each have 4 NICs, each of which are on separate unmanaged switches. The connections are made in a corresponding way ... e.g. eth0 of each machine are connected via switch 0, eth1 are connected via switch 1, etc.
How do I monitor network traffic usage on Xen virtual machines running on Debian GNU/Linux Squeeze?
I have a number of Xen virtual machines (domUs) running on a few physical machines (dom0s). Each domU can be started on or live-migrated to one of the physical machines.
I would like to monitor and account how much network traffic is used on each domU.
I have a "development" KVM server here at the office, setup in a bridged networking setup with a few KVM guests running on it. For each KVM guest a virtual interface is created on the node with the name kvm[id].0 e.g. kvm126.0 when the guest boots.
Written by: Beverley Head | Published in: Cloud ComputingThe first five nodes of the $50 million Research Data Storage Infrastructure (RDSI) project have been announced.
I am working on a thesis research project, and I am having some difficulty figuring out how to get iptables (running on the KVM host) to block traffic (or rather, manipulate traffic) destined for a BRIDGED KVM guest.
This question is a follow-on from Dedicated NIC or dedicated port for iSCSI?
Excluding the hardware iSCSI initiator point that was made in the accepted answer to the above question, it seems that using separate port(s) on a multi-port NIC for iSCSI is pretty much going to meet the recommendation of using "seperate NICs" for iSCSI traffic.
I'm in the process of planning a small iSCSI installation
