Very well, it seems that if instead of doing posts lengths, I do short, I write that more ….no I will speak much of the topic just in case

Now we are going to create a storage pool in KVM with libvirt, we will use the VG that we create in the previous post of pool of the following way:

East is going to be rapid and brief but I hope that it should help you as to me. He needed to reduce a Volume Group (VG) to create other, the original (vggentoo) was composed by two devices RAID1 for software (md0 and md9).

Did the result of the operation have to be 2 VGs, vggentoo with md9 and vgkvm with md0 and as I have done it?

sergio@thor: ~ $ sweated vgdisplay-v vggentoo

We make sure that what we have occupied in md0 us fits in md9.

sergio@thor: ~ $ sweated pvmove - to and/dev/md0/dev/md9
/dev/md0: Move: 0.3 %
/dev/md0: Move: 0.6 %
…

Finally we decide and we already have the updated house servant!! The hardware that runs at present is:

• CPU: AMD Phenom (tm) 8450 Triple-Core Processor
• RAM: 4 x 1GiB Kingston DDR2 800MHz
• HD: 2 x 200GiB Digital Western
• Mobo: Gigabyte GA-MA78GM-S2H

We might have started the system that we had installed since the previous processor also belonged to the family x86_64 but we decide to realize a new installation since we wanted to mount servants virtualizados as what the system with the hypervisor, in this case KVM, does not need to have everything what had the ancient servant.

Do we return to the attack with the granduyón, in the last post we remain just to begin the installation, have the CD truth? since forward!

As soon as the portable one was started, we will have ahead a bare commands line … the first thing that we must do is to form the network, if it is that we do not have clear DHCP in our network. If our network has automatic directions allocation, as in my case, we will not have to worry about anything since netplugd he will take charge of everything. If we have no DHCP, we will have to form the network using the assistant or to hand, as let's want: Si no tenemos DHCP, deberemos configurar la red usando el asistente o bien a mano, como queramos:

livecd ~ # net-setup eth0

Being still the assistant we will have the network formed concerning a few seconds.

Particionando the disc …
To work with the disc we will use cfdisk, we are going to create two divisions, the first one will be of 512MiB for / boot and the following one of approximately 120 – 130GiB that it will serve to us to create a VG. We will leave some free GiBs to lodge the swap out of RAIDs and LVMs: why? everything patience will come ;). todo llegará paciencia….;)

Is it already time to take this M$ Vista from us of above, that we are going to install? Gentoo! And because? you can ask that … well, all right it is with the distro which more comfortable I meet. I realize that portage since implementation is not the best of the world, for example, it might be more rapid … but good inside the imperfection that we might find in any software as our needs, Gentoo for me is perfect Y porque? podeis preguntar…pues bien es con la distro que más comodo me encuentro. Soy consciente de que portage como implementación no es la mejor del mundo, por ejemplo, podria ser más rápido…pero bueno dentro de la imperfección que podriamos encontrar en todo software según nuestras necesidades, Gentoo para mi es perfecta

What is the idea?
Making use of two discs of the HP Pavilion dv9890es let's mount the system with the discs in RAID-1 (mirror, mirror …) thus we will have all the resulted information and in case of casque of 1 disc ….estaremos brans! But do I remember that to have the discs in RAID-1 is not a stand-in of the safety copies OK? As the yankees would say, shit happens or what comes to be … (from slightly more polite form) everything can go on since a RAID-1 does not protect us from human mistakes, I even remember that time mounting a RAID-1 for software that I was wrong of division and remained without / home that precisely wanted to answer! Como dirian los yankees, shit happens o lo que viene a ser…(de forma algo más educada) todo puede pasar ya que un RAID-1 no nos protege de fallos humanos, aun recuerdo aquella vez montando un RAID-1 por software que me equivoqué de partición y me quedé sin el /home que precisamente queria replicar!

To part of the RAID-1 we will mount LVM, which will allow us to manage the space of our divisions of a more comfortable form in case that we lack in some place.

How do we start?
The first thing that we are going to do is to lower an iso minibadly of gentoo for amd64, if I do not remember badly Gentoo a stable iso does not publish from 2008.0-r1 so we will look for a mirror with autobuilds, that are not any more than iso done of a form automatic and published to have anything more recent than the official version.

The advantages of these autobuilds are basically that everything what they take it is much newer, what I was walking looking is to have a recent kernel during the installation and not to find me with problems of absence of drivers of network, SATA, etc …

Good like late Christmases gift me a portable one has fallen down, that the ancient one was already needing a plan I renewed later more than three years.

Like lately my needs have changed this time I have looked for something that allows me to work comfortably at home but that simultaneously could move it (although the back means to destroy me a little), he was looking for something of 17 ″ with a good resolution, enough memory and a CPU that me lasts at least so much or more than that of my ASUS W5A. Finally the product that for price and for characteristics better was fitting to my needs was a HP Pavilion dv9080es that a Core 2 Duo wears to 2.4GHz, with 3GiB of RAM, 2 discs SATA of 160GiB, NVIDIA Geforce 8600M GS, Reader of Blue Ray, screen widescreen of 17 ″ with resolution of 1440×900 and typical trifles of a portable one nowadays how webcam, bluetooth, etc …

The truth is that for the time being I am very satisfied with the buy and with the seller, I have acquired it across eBay, specifically of the shop that there has HP where 0 sells products KM as they call them they, that there are only products that went out with some defect and after conditioning them for his sale, they cannot sell them as new … but they sell them with a year of guarantee and saving yourself a few pelillas

Since I mounted MythTV I have had problems to syntonize the channels of Antena3 (Antena3, Antenna. Neox and Antenna. It nongoes). On having scanned the channels, everything was correct, that is to say, the tuning of these channels was obtained correctly but at the time of visualizing them in the frontend it was not managing to go on from Partial Lock (L_s).Nova). Al escanear los canales todo era correcto, es decir, se conseguía la sintonización de estos canales correctamente pero a la hora de visualizarlos en el frontend no conseguía pasar del Partial Lock (L_s).

After several hours looking for information of because it is possible to produce this error I understood something of the logic of the structure of information that MythTv keeps in MySQL. I managed to realize from which the problem was with the stage channel and dtv_multiplex.

It seems that Vodafone is a little saturated by the high ones of ADSL and for it we go waiting almost 1 month and we still have not even the router …

Fortunately, a few months ago we hire a Movistar flat rate for my HTC TyTN (aka HTC Hermes) and till now we have been using it with me portable connected for bluetooth. I have to say that there is sorrow of which the speed is not anything of another world … it allows me to sail without problems and it is turning out to be stabler than he had never waited.

Finally I have got tired of waiting and have prepared two of my cacharritos (Linksys WRT54GS and Soekris net4801) so that they give connectividad WiFi and to Internet across the Hermes.

And this is what we want to explain in a series of posts, step by step, beginning for the connection between a PC (me portable) Internet across a device with Windows Mobile 6.1 (my HTC Hermes).

Very well, I believe that I have managed to do the first version of the script who was commenting in one of my last posts. At the moment it is a preliminary version, it neither detects if the TV is used, nor does big control of anything … but for the time being it realizes his principal task.

Only it uses standard console hardware, tzap (of the bundle media-tv/linuxtv-dvb-apps) and tv_grab_dvb. To start we will install the necessary bundle:

sergio@sjr ~$ sweated it emerges-Dv linuxtv-dvb-apps

What sound the information EPG?
EPG is the information transmitted by the digital channels publishing his programming.

How can we obtain it from the commands line?
To carry out this task from the line of commands of our machine Linux we will need to use tv_grab_dvb while we syntonize a multiplex in our card DVB.

A multiplex comes to be a set of channels that share the same frequency, they divide the sign in a concrete frequency and manage to transmit different channels. To syntonize one only we have to throw our reproductive TV program and to put a channel from which let's want to receive the programming.
