Hello
I am trying to install KVM based VMs on my machine. First
Timer...little idea on actually configuring related networking related
issues. Am planning to follow this howto:
http://www.howtoforge.com/virtualization-with-kvm-on-a-centos-6.3-server
My trial machine is a server cum desktop with two network ports..eth0
is normally used for LAN & Internet access...eth1 is reserved for use
with LTSP which is to be configured later. I need my VMs to be
reachable from the internet by ssh & vnc etc. required ports will be
forwarded from the Internet router.
I propose to use subnet 10.0.1.0/24 for my virtual machines. Can
someone please advise the content of bridge configuration file at
/etc/sysconfig/network-scripts/ifcfg-br0, as given in the howto? The
two bridges ltspbr0 & virbr0 shown below, are created by packages
installed & not by me, so if any modifications are required in
them...I need to know. Also, please advise if it is possible to get
the VMs to use a 3G usb device for Internet access through the host
machine Network Manage, in case Internet access through eth0 is down?
Though this is not a priority at this stage, as I am just learning to
use my first VM, but I'd like this feature if it is not too difficult.
With regards.
Sanjay.
