Building a C5 chroot on a C6 machine
I'm trying to do something slightly silly; rather than having a C5 machine
and a C6 machine around for compiling and testing, I want to create a C5
chroot area. Something similar to "mock" but using lvm snapshots and some
local config specific stuff.
(Potentially even using Linux Containers to enter the chroot environment).
So I thought I'd build out the chroot...

Steve,
Thanks, makes sense.
I just don't see why I have to effectively waste an extra IP address to get
my connection established.

error configuring a public bridge --> uvt-kvm: error: libvirt domain 'newtest' has no NIC MACs available.
Hi all,
First at all, excuse if this is not the right place for sending this email.
I'm using ubuntu 14.04 server edition and i'm trying to deploy some virtual
machines in a server in such a way that they are visible in the same
network that the host machine.
The tools I'm using are the uvtool package and libvirt.
The error I'm getting is the following:

VLAN issue
Do you need the whole configuration? On the switch end, we have the
relevant VLAN (VLAN 48) with the assigned IP address of 192.168.48.101 and
the range of ports (Gi1/0/1 - Gi1/0/8) assigned to that VLAN.
Seems - and acts - like a legitimate setup and works fine, except for this
particular instance.
Thanks.
Boris.

can't disable tcp6 on centos 7
Tim,
where did you installed this nrpe package? is selinux running enforcing
mode (getenforce command), try disabling with setenforce 0. why you are
running it under xinetd as usual way is to run it as nrped daemon.
test against with check_nrpe, not using telnet.

Solaris /bin/sh was a real real dumb version of the bourne shell.
Solaris included /bin/ksh as part of the core distribution (ksh88 was a
part of the SVr4 specification) and so many scripts were written with

VLAN issue
Hi Boris,
what I'd like to know is the actual VLAN configuration of the switch
port (link-type and tagged and untagged VLANs). When I look at the
switchport coniguration here I get (among other things):
...
Port link-type: trunk
Tagged VLAN ID : 8, 1624
Untagged VLAN ID : 10
...
Here is my suspicion:
Your ports have an access link-type with an untagged VLAN ID of 48. That

If you are on a trunk port then your machine needs to be configured
for VLANs. If you are not on a trunk port then your machine needs
to be configured normally.
It _sounds_ like you have configured your machine for VLANs but are not
on a trunk port.

Disabling IPv6 in CentOS 4.7
I thought I'd done that standard stuff
/etc/modprobe.conf:
alias net-pf-10 off
alias ipv6 off
/etc/sysconfig/network:
NETWORKING_IPV6=no
But on reboot I still see ipv6 entries against the eth devices, ipv6 module
is still loaded, and sit0 tunnel is present.
What needs to be done to disable ipv6?

Xen vs. KVM console
Hi,
I'm trying to get the console support in KVM working as well as on Xen but
right now I'm stuck. I followed these instructions:
http://prefetch.net/blog/index.php/2009/06/17/redirecting-the-centos-and-fedora-linux-console-to-a-serial-port-virsh-console-edition/
This works out fairly well except that I cannot watch the bootup of the
machine in the vnc console anymore only on the
