Unless you are using a version of Firefox which was packaged by your

Re: auto-maximize a logical partition with ext3

[Etzion Bar-Noy]

DD is a lousy OS replication tool, and I would not have used it. Using
simple (!!!) scripting to replicate systems, with any possible combination
of sfdisk, LVM, mkfs.ext3, resize2fs would probably be better, not to
mention - faster.

Example:
Boot; create a new partition layout on your new disk using sfdisk and an
answer file (hint: read the man pages); format partitions (all full size,
yes?); mount partitions; replicate using 'tar' over network, or over NFS
share (better do it from a single tar file, or compressed tar file. It's
faster to decompress than to compress); mount/tar remaining partitions; fix
boot loader; reboot

I have done so countless times in a set of automated tools. Easiest possible
solution. DD seems faster on first look, but sets so many additional
problems (amongst is the one you have described. Others deal with different
hardware layout), and you copy lots of dead nothing.

that solution has come to mind, and I have seen one case where it was
used (to create, not resize). there's no need even for expect, you can
simply redirect the input because the interaction is well known in
advance, but it's a very ugly solution I hope not to have to implement

Re: Linux has won!

[Steve G.]

One machine is a netbook, and is barely usable as it is...

The other could handle a VM, but I have never had any luck installing
Windows into a VM. Using windows as my main OS is too painful - always some
crap to take care of, not worth the hassle.

Finally, vmware requires recompiling any time the kernel changes, and
virtualbox on my other linux box was a resource hog. This new one may be
better, as it does have the right hardware to natively support VMs, but I
have not tried it yet.

At least in the case of VirtualBox, USB can be redirected from host to
virtual machine.
When you are running a virtual machine, VirtualBox offers a menu and one
of the menu options is to open a list of USB devices connected to the
host and make it possible for you to select some of them for redirection
to the virtual machine.
Note that the keyboard and mouse receive special handling.

This is a good point, but I think the situation is now different: It's not
just one type of business device that has Linux - it's almost every new
"smart" device, and devices that people commonly bring into their home.
And many of these devices (especially Android) do give the users some feeling
of an "operating system", unlike the situation of ATMs.

Right. Linux is not receiving the publicity it deserves. So it has one,
but nobody knows it yet ;-)

But line of reasoning brings, as I exlained, two questions:

1. There is a trend of the traditional "desktop" being replaced, or just
   eclipsed, by "alternative" devices, such as tablets, smartphones, tvs,
   streamers, networked hard disks, etc. If all of these use Linux but
   traditional "desktops" still don't, in what sense has Windows continued
   to win?

2. If people get used to alternative UIs from all these devices, what will
   they have left as an excuse to choose the expensive Windows and Office
   on their desktop?

Re: Linux has won!

[Steve G.]

FWIW, I have machines running dual win7/ubuntu. I use windows for one thing
only - managing podcasts on iPads with iTunes (seems that Apple has Windows
software, but not Linux (maybe this is how they repay Windows for the
investment when Apple was going down the drain a few years ago).

For my needs, Windows is not worth the trouble. Virus checks, spyware
checks, daily updates that can sometimes take hours, it is slower to start
and shut down, slower in performance, and while it does not crash as often
as XP and NT and 2000 used to, it is not as stable as Ubuntu. The only
advantage it does seem to have is hardware compatibility.

So I have it in use 5 minutes every couple of days, and the rest is pure
Linux.

Today over lunch, a few of us were talking about Linux vs. Windows.

Somebody said, among other things, that he prefers Windows because it is more
popular. Then it dawned on me: We're so used to thinking that Linux is a
niche OS that only 1% of the people use at home, that we (or at least I)
missed the fact that this changed! Over the last few years, suddenly that is
no longer true: Today there are probably more copies of Linux than Windows
running in people's homes!

Why am I saying this? Because while most "traditional" PCs are still running
Windows, new kinds of consumer home have appeared to replace or accompany
the home computer, and many of them are running Linux:

   * Smartphones and Tablets with Android, WebOS or MeeGo.
   * Media streamers (e.g., Xtreamer, Popcorn, etc).
   * Residential gateways (a.k.a. home "routers").
   * DVRs (e.g., Tivo)
   * Televisions (e.g., from Samsung and Sony)
   * GPS (e.g., from Garmin)
   * Networked hard disks (e.g., WD My Book Live)
   * Personal video screens on airplains

So probably the number of home installations of Linux, in one of these home
devices, is already greater than the number of home installations of Windows!

And of course, add to this the fact that Linux is also more popular on
servers, e.g., Google's and Facebook's servers - over a million (!) of
them, all use Linux - so even if your PC is running Windows, the Web sites
you use are actually based on Linux.

Some might argue that the fact that these devices use Linux is irrelevant,
because their Linux is not exposed to the users. I argue that this is not
accurate: Some of them do expose an operating system (e.g., Android), in some
of them you need to be aware of Linux to add extensions or understand their
on-disk formats. But more importantly - The fact that these devices are *not*
based on Windows is what matters. It is starting to educate the users that
Windows isn't the only "allowed" user interface: People used to hate Linux's
UI (e.g., Gnome, KDE, OpenOffice) because they are different from Windows'.
But now everything is different from Windows: Android is different from
Windows, Apple iOS is different from Windows, Xtreamer's menu system is
different from Windows, Gmail's UI is different from Windows - suddenly Linux
doesn't look that "alien" any more.

And finally, as Linux-based devices outnumbers Windows-based PCs, and perhaps
even out-costs them, the amount of investment into Linux development will
increase, to the benefit of all Linux users.

So,

We won!!!

Vive la revolution :-)

sizes, installing a few dozen machines every day. I would like to make
the process more unified - install the same 4G image on all medias (dd)
and then maximize sda6, the last ext3 partition, and naturally, the
underlying extended partition sda4.

The only tool that automates resizing like that is parted, and it still
needs a precise partition length instead of "use all available space",
and won't resize ext3 if I don't turn off the journaling first (make it
ext2). I tried deducing the maximum partition size with fdisk -l and
other sfdisk instead, but each uses different units and I have no idea
how to convert them all correctly so I'm left with working, non
overlapping partitions.

I'm prepared to do it the hard way, I just wondered if there's a tool I
missed or an existing script that already does this.

Thanks.

I have had a very good track record with Proxmox VE:
http://pve.proxmox.com/wiki/Main_Page

It's a Debian with both KVM and OpenVZ, built-in clustering and a
unified Web interface to create and manage the machines.

For the record, the direct replacement for Linux VServer would be OpenVZ
or (for newer kernels. Not Centos 5.x) potentially lxc.

Hi Tom,

A couple of questions:

1. Are you talking about Internet facing environment or are you talking
about an internal server?

2. What are you planning to run on the server(s)? Linux VM's? Windows
VM's? What level of support do you require?

3. As others have mentioned, CentOS 5.4 is getting old, I'd use CentOS
5.5 instead.

4. Beyond that, given the difficulties CentOS is having in releasing
both CentOS 5.6 and CentOS 6 (RHEL 6.1 has already in beta testing while
CentOS developers have no clear roadmap for CentOS 5.6 and 6.0 release).

5. Having said all that, I'd either:
a. Buy RHEL 6.0 (if you require small number of VM's)
b. Buy RHEV 2.2 (if you require better support and/or larger number of
VM's; should be twice as expensive as RHEL 6.0)
c. Use Fedora 14/x86_64. (If you don't mind the 13 month-long support
cycle or this is an internal server that doesn't require daily patching)
d. Switch to another distro (SLES?)
e. Switch to CentOS + VMWare server.

In my case, I usually opt for Fedora for in-office [1] use and RHEL for
out-office use. But than again, I will be able to give far better advise
with some additional information.

Xen should be better for servers.
You can download red hat 6 from red hat site (free register, free download
for 30 days or so, you can use it forever, but is not legal :).

Ram on.

Just demand RHEL6 from them. RHEL6 includes kvm+libvirt and you get support from
Red Hat (as long as you use libvirt to start kvm guests).

Smart choice. RHEV is... I don't even have a word for that. And that's even
before the fact that you need Windows(TM) Server (???) 2008 (???) R2 (???
!!) to actually use it at its latest version. (or so we were told...)

Re: Looking for KVM consultant

[Tom Rosenfeld]

We spoke to Matrix, but they of course want to sell us the whole RH RHEV
suite. We just want the open source stuff.

About the version: I will check, I just did a yum install. How stable is
CentOS 6? The only thing the physical host will do is to host KVM. Should I
be using CentOS 6, or perhaps something lighter?

Thanks,

Being in .il, who can help with Red Hat's technologies better than Matrix?

And yes, 5.4 is old, kvm works much better in 5.6, and even better in 6

Re: Looking for KVM consultant

[Hetz Ben Hamo]

Hi,
Few things:

1. Did you compile KVM from source? CentOS 5.4 is really old, and for best
results you should either use RHEL 6 or the latest Fedora.
2. It's pretty hard to find a consulting for KVM. Frankly, they're doing a
lousy job of marketing it, specially for hosting businesses.

Good luck,
Hetz

Looking for KVM consultant

[Tom Rosenfeld]

Hi guys,
We are looking for help setting up KVM in our production environment.
We have been using Vserver, but want to move to KVM which has many more
tools for management.

Our initial tests under CentOS 5.4 have not been good. The KVM guests often
hang when they are under load.

Any recommendations?

Thanks,
