Simple routing question
We use a dual homed CentOS-6.3 host for our Internet gateway router. Its internal nic (eth1) is configured such that the address 192.168.0.1 is one of its aliases. # cat /etc/sysconfig/network-scripts/ifcfg-eth1:192BOOTPROTO=none BROADCAST=192.168.255.255 DEVICE=eth1:192 IPADDR=192.168.0.1 IPV6INIT=no MTU="" NAME="LAN - Non-routable" NETMASK=255.255.0.0 NETWORK=192.168.0.0

Strange network failure on C6
Hi all! I'm running C6 (up to date) on x86-64. have been running on the same system for over a year. a couple of times lately access to the outside network has suddenly stopped working for reasons that I didn't figure out until it happened again yesterday. I had the time to fool with it, yesterday, so after quite a bit of head-banging I found that it had no default route set up (to make

CentOS-5.4, KVM, QEMU, Virt-Manager and kvm-qemu-img
What is the correct combination of packages to configure and manage VMs via virt-manager undet CentOS-5.4? If I use qemu then while virt-manager works I obtain SELinux alerts with respect to the real-time clock. If instead of qemu I use kvm-qemu-img then virt-manager simply does not work. It starts but it does not find any form of qemu and the selection boxes are all greyed out. Further, do I

The save button remains greyed out. -- *** E-Mail is NOT a

Using Puppet to swap eth0 and eth1
I''ve been using Puppet now for a month or so and I''ve come to a problem that may warrant an additional Puppet metaparameter. I''m advocating the addition of a metaparameter called "preaction" (or something like that), which will perform some arbitrary action before the resource is modified. There may be a way to do this within Puppet already (with some

SELinux and KVM
I am trying to set up a test kvm virtual machine on a core2 quad system. I have managed to thread my way through bridging eth0 and I have a CentOS-5.4 dvd iso prepared. Using virt-manager, when I try and add a new guest then I get the error reproduced below. Now, I know that I can 'fix' this by building a local mod via audit2allow and installing via semodule. However, I cannot seem to
