En effet.. Mais c'est une solution : monter le disque sur l’hôte et le 
partager avec la VM.

La virtualisation ne sert pas qu'à résoudre des problématiques réseau.

Elle permet aussi de concentrer sur une seule machine physique 
plusieurs rôles qui ne sont pas compatibles entre eux (requérant des 
os totalement différents)


Elle permet aussi de réduire l'impact de pannes. Si un service est 
impacté dans une VM, il a peu de chance de propager des effets de bord 
à un autre service (mais l'hôte reste un point de faiblesse).


Le cloisonnement par VM peut aussi être une solution pour ralentir ou 
limiter l'impact d'un intrus. Une fois dans une VM, si le réseau est 
bien configuré, on peut ralentir ou stopper l'étendue de l'attaque.


Une VM avec un seul service, en panne, peut se reconstruire plus 
facilement qu'un système avec 5 services "entremêlés dans une unique 
instance du système d'exploitation. La restauration par sauvegarde 
peur aussi aller plus vite.



Enfin, une machine virtuelle peut être capturée dans un état 
instantané, un Snapshot, avant de faire un upgrade risqué. Si ça se 
assez mal, on revient à l'étendue limitée de panne. Une restauration 
d'un Snapshot prend quelques secondes a quelques minutes. C'est bien 
plus rapide que  restaurer un backup. Il faut compter le même ordre de 
rapidité pour créer un Snapshot. C'est un confort incomparable avec 
une sauvegarde traditionnelle de précaution.


Enfin la portabilité d'une VM d'un hôte a un autre est plus facile à 
assurer car le matériel virtualisé est invariable tant que 
l'hyperviseur reste le même. Et encore, entre les différents produits, 
le matériel émulé ne change pas énormément.




Mmm, c'est exact, mais il faut séparer deux problématiques bien distinctes :

1- la virtualisation proprement dite, quand on a besoin de machines (VM 
Windows, ARM...) complètement différentes pour lequel QEMU est sûrement 
le plus adapté.


2- l'isolement des fonctions, les containers, pour laquelle un outil 
linux m’apparaît comme bien plus efficace et génial, tant que les VMs 
restent en linux  : LXD...


La description de la virtualisation de Dethegeek ci-dessus  me semble 
s’appliquer plus à l'isolement des fonction qu'à la virtualisation 
proprement dite. Le deux outils sont magiques mais chacun à sa place.

Quand on installe Debian sans interface graphique, sauf erreur seule

The ability to clearly describe your problem!

Sorry I tried to be minimum... But here are more details?


What did you do?
   I assume you wrote some c code.

Yes, this  code above is written in c (c++ in fact but I have simplified).

   Did you compile it? And if so, how?

Yes, with default tools (gcc under debian bulllseye linked with libodbc)

   You installed odbcunix I assume.
   How did you configure it?

Correctly.

   What is the output of "odbcinst -q -d"?


Correct :

[PostgreSQL ANSI]
[PostgreSQL Unicode]


What did you expect?

That my c program produces the same list


What did not work?
  Include logs, error messages.


Logs and error messages : none (This is the heart of the problem)



What did you do to solve your problem so far?

I have reduced my problem - which is much more complex - to the simplest 
test prograam.


And I ask for help, as I have no more idea after many hours.

https://wiki.archlinux.org/title/Backlight  may warrant a read.

I have to suspect acpi_backlight=vendor on kernel command line is not taken
well by the 3840x2160 screen.


I have tried to remove acpi_backlight=vendor, but

https://paste.debian.net/1204642/

shows no significant difference with https://paste.debian.net/1203999


Whatever caused [ 313.732] (WW) modeset(0): Option "PreferredMode" is not used
I can't tell.


My idea is that this reason is that the limitation to 30Hz is not 
described by



Section "Monitor"
    Identifier  "HDMIcon"
    HorizSync   30-135
    VertRefresh 29-31
    Option  "PreferredMode" "3840x2160"
EndSection

So, I have used gtf to create a 3840 2160 30 Modeline. As i have read 
the cvt is more "modern", I trie now with


Modeline "3840x2160_30.00"  338.75  3840 4080 4488 5136  2160 2163 2168 
2200 -hsync +vsync

 And...

It fails too with :

https://paste.debian.net/1204643/

With the following result :

- eDP-1 is dislayed correctly

- HDMI seems to remain as before startx is executed, but a cursor, 
certainly a X cursor appears in the high left corner of the screen. This 
cursor seems to move a little when I move the mouse but returns 
immediately to the corner. I have to kill kill the session with another 
console.


I think that either I have not found hye good "Modeline" either it is a 
bug (maybe in the driver), but it is surprising that I am the 1rst to 
have this problem as this monitor is available since 2019...

There are two X drivers for Intel IGPs capable at least theoretically of
supporting 3840x2160:

Intel DDX, provided by xserver-xorg-video-intel
Modesetting DIX, provided by xserver-xorg-core

The Intel driver has been essentially in maintenance mode for the past 7 years,
its main reason for keeping it maintained being it is the only driver available
supporting ancient Intel IGPs. The only way to tell if it works better on newer
hardware is to try it. Don't expect much from anything as new as yours using the
Intel DDX instead of the Modesetting DIX.

Either of the two drivers can be specifically selected via a .conf file in
/etc/X11/xorg.conf.d/, e.g., assuming xserver-xorg-video-intel is installed:

# file: 15-ddxdrv.conf
Section "Device"
  Identifier "DDX"
Driver "intel"
#   Driver "modesetting"
EndSection

selects the Intel DDX, blocking X from attempting use of the Modesetting DIX.


I have tried intel driver which does not work but does not crashes.

I come back to "modesetting" driver.

I forgot something important to this thread. I got a broken 55" 4K LG TV
for free 8 weeks ago. I spent $40US on parts to fix it.

I just tried connecting it to a Kaby Lake Intel PC (HD 620, not UHD 620)
via direct HDMI, along with an ordinary 1920x1080 Samsung HDTV via 
DisplayPort
to HDMI adapter, using openSUSE 15.2. With only the LG connected, X 
opened up
in 3840x2160@30 automatically. With both connected, both come up in 
1920x1080@60.
However, xrandr --output HDMI-2 --primary --mode 3840x2160 --output 
DP-1 --mode 1920x1080 --above HDMI-2
worked a charm to set 3840x2160@30 on the LG and set the small 
Samsung above

the big LG.

Rebooting to Bullseye to try the same, I can't get the Samsung HDTV 
out of
unsupported mode, even though xrandr reports the Samsung is using its 
native
mode, or trying with any other supported mode selected. This smells 
like a

Bullseye bug waiting to be reported.

Next I tried openSUSE Tumbleweed. It works as expected there too:

You should have no need of gtf or mode creation with 620 graphics. Mode creation
via xrandr is an anachronism. X knows very well how to auto generate modes when
provided with needed specs. If EDID, the usual source for the data, is broken,
then provide the specs via:


Yes, EDID is wrong and does not show 3840x2160 warranted by Samsung for UR59C 
32".
 


/etc/X11/xorg.conf.d/50-monitor.conf
containing the horizontal sync and vertical refresh rates for your display, 
e.g.:

Section "Monitor"
Identifier  "Default Monitor"
HorizSync   28-85
VertRefresh 50-100

Option  "PreferredMode"   "3840x2160"

EndSection



This has no effect but I suppose the problem is due to the 2 screen 
configuration. So I have tried replacing Identifier with :


 Identifier    "HDMI-1"

But it is not better...

I have put in https://paste.debian.net/1203873/
the content of  .local/share/xorg/Xorg.0.log

It seems that the Modeline 3840x2160 is recognized, but the 30hz

Acer swift5 specifies 3840x2160 but with a 30hz limitation, no more 
frequency.

Failure to use 3840x2160 30hz with Intel 620 chipset

When I try (under bullseye) :

This is more complicated than you might wish :-)

The problem centers around the definition of "slow": clearly, some
resource is being hogged by your 'cp', but which one(s) will depend
much on your hardware.
in fact, in this case, it is a copy of mailboxes (many small files) from 
a location to another, the whole on a brtfs RAID1 device...


Since you have tried 'nice' with no effect, let's assume that this
resource isn't CPU.

Yes, top, shows it (what it is  allowed to run ;)

  Then, you might have a look at 'ionice' (from
the package util-linux). But too little RAM might be as well a
problem.

Another avenue might be using rsync, which offer a rate-limiting
option (--bwlimit).


Thank you, sure I shold use rsync or ionice.

Anyway, it not a reptitive tasks, but it was yo understand...

Because you did exactly this. su(1) says:

Make a habit of using 'su -', as this behaviour is here to stay.



Is it a bug somewhere in debian ? Installing snap ?

It's a change in Debian, see #833256.
There are two su utilities, from 'shadow' and from 'util-linux'.

Pierre Couderc composed on 2018-07-12 12:20 (UTC+0200):


The point too is the font is very small on these Acer Swift when nothing
is installed, and as I am a bit old I have difficults to see characters...

While dpkg-reconfigure console-setup would be the preferred way to make console
text bigger, it takes time and effort to set up. Last century I found a simpler
approach that works well to produce bigger console text: tell the kernel to use
a video mode that reduces screen resolution via cmdline option at boot time.
This method can be applied temporarily with Grub2 using the e key at its menu.

I don't find anything objectionable to using reduced resolution in fullscreen
framebuffers, so this simplicity works well compared to finding, selecting and
installing a different console font, and having to do it all over again when I
use another PC or display. In fact, I've yet to find a console font I like as
well as the one the kernel uses by default, so the third thing I do on a fresh
install is dpkg-reconfigure console-setup to employ FONTFACE="" & FONTSIZE="" in
/etc/default/console-setup (#2 is apt install mc following apt update).

To illustrate, if a screen with native mode 1920x1080 is in use and its console
text is too small, I append video=1440x900 to make the text slightly larger,
video=1280x720 to make it larger still, or video=1000x600 to make it really
large. On a video=3840x2160 screen I use video=2560x1440 or video=1920x1080,

Have you tried experimenting with different font faces?

 # dkpg-reconfigure console-setup

Different faces permit different sizes, which you can read about[1] in

  $ man 5 console-setup

under OPTIONS, in the section on FONTFACE and FONTSIZE:

| FONTFACE and FONTSIZE

| Valid font faces are: VGA (sizes 8x8, 8x14, 8x16, 16x28 and 16x32),
| Terminus (sizes 6x12, 8x14, 8x16, 10x20, 12x24, 14x28 and 16x32),
| TerminusBold (sizes 8x14, 8x16, 10x20, 12x24, 14x28 and 16x32),
| TerminusBoldVGA (sizes 8x14 and 8x16), and Fixed (sizes 8x13, 8x14,

| available font faces are Goha and GohaClassic, each in sizes 8x12,

I don't know about your particular device, but FWIW the Terminus
fontface frequently proves helpful for me.


I had not. And on your advice, I have changed to terminus 10x20 and it 
is very fine for me now !

You can now access packages on DVD-1. But what about DVD-2, DVD-3 etc?
If not having a network connection is to be a feature of this machine,
you could consider having as many DVDs as you want on the hard disk or
on a USB stick. You might find the Installation section of the wiki
gives a relatively easy way to do this with a single entry in the
sources.list, rather than with separate entries.
Thank you very much. Sorry, I cannot explore this way these days,  I

Merci  beucoup, Curt I had seen this kind of solution, but it did not work
as I had not discovered the "trusted" option.
Now, I have to understand why it says me :

Malformed line 6 in source list /etc/apt/sources.list (URI parse)

URI parse - apt does not understand the URI you have in sources.list.


when my line 6 is :

deb [trusted=yes] file:/media/cdrom/ stretch main

Did you type this into your mail or was it a copy and paste? (The URI
above works for me).


And if I remove the , I get the message about file not signed...
  [trusted=yes

If you get this message then apt finds the URI acceptable. If the URI
is not ok, it won't get this far.

I doubt that bug #872543 has anthing to do with your issue.


I cannot copy paste as I have not access to lan/wan
So I typed this in my mail..

As you point me in the good direction, I have removed the full line and

I suppose that I did key some bad character somewhere...

I don't see exactly how that bug explains your malformed line error;
there is also the  '--allow-unauthenticated' flag to apt-get that you
might try if [ trusted=yes ] is truly the problem.

  apt-get --allow-unauthenticated ...



No apt works as source.list seems wrong.

Ah, I see you're using LuaLaTex to compile the document instead of
pdfLaTeX. The .tex file you're using uses the T1 font encoding
(“\usepackage[T1]{fontenc}”) which is incompatible with the LuaTeX
engine. If you do not load the fontenc package, you should be able
compile the file using `lualatex`.
So either compile using `pdflatex` or using `lualatex`, but then remove
the line “\usepackage[T1]{fontenc}”.


Oh yes, this is the point. By removing fontenc, all is good.
Thank you  and thank you all.

I believe you have the OTF font installed, but pdfLaTeX cannot use OTF
font. (However, LuaLaTeX and XeLaTeX can be used to compile documents
using any OTF font.)

Did all this.
All my free -th results looked the same.
Could it be it was already there?

Assuming there is an advantage to this, how does one get it going on startup.
I HAD a sysinit script for it at one time, before the new days of systend.


I have decided to use the following script and it seems to work :

git  clone https://github.com/Jiab77/systemd-zram
cd systemd-zram
./install.sh

You can the remove systemd-zram directory.

Here you can modify /etc/systemd/zram.conf from 33% to 50 for next 
reboot… But it is only to adopt the same policy as Ubuntu,  but the 
original prefers 33%...

I didn't even know what it is -- but the zram(8) man page and a little

I assume you'd want to load the zram kernel module (sudo modprobe zram,
I'd guess) to be in in the fun.

There's some doc about the Linux kernel module itself (just follow the

Let us know how it works out and... make a backup first!

How to use zram ?

[Pierre Couderc]

I have found no howto for zram under debian,  nor even the word "zram" 
in the archives of this list !


I have tried to use zramctl but it refuses with :

root@nous:~# zramctl --find --size 1024M
zramctl: no free zram device found

I suppose I should init something somewere, but what ?

On the contrary ubuntu has a dedicated zram-config to make the job.

Thanks for any help.

Again: nobody is suggesting it's a hardware problem. Just that we
suspect that you *can* convince your BIOS to "simulate" a traditional
keyboard, just for GRUB. Once the full linux is up and running,
USB is not that much of a problem.

So the questions there ("BIOS?", "PS/2 interface?") are not because
people here don't know what they are doing, but rather to get a feeling
on what kind of machine we have.

Machines having USB *and* PS/2 keyboard interface almost surely have
a way to set "legacy peripherals" in BIOS (this was the transition
period) *except* the very first ones. But if the BIOS itself works
with USB, then... nearly sure.

figuring out why the early stages of the install aren't happy (please
note, they work fine for others, including myself, so whatever it is it
isn't a straightforward "Debian doesn't work" problem).
Yes, I do not like the "Debian doesn't work"answer.. But it is not 
because it has worked for you that it works for all.
Anyway, I cannot says anything else that "when I put debian install

In this case,
the suggestion I made about kernel boot parameters is the best idea we
have so far to work with and would bear further research.
Yes, but I do not know how to change boot parameters. I put my CD in the 
reader and it boots before I can change anything...

Should I build my own install disk...?
I am still googling and have not soon found.

This PC was under XP and did work fine. It is a debian (or linux ..?)

I have a feeling someone else faced a similar problem somehwat recently
(say in the last 6-12 months) and there was a boot parameter that sorted
it for them. I'm afraid I don't remember details. The closest I have
personally come to this is finding a Bluetooth keyboard not working at
that stage, but a wired USB keyboard did work. That was a release or two
of Jessie ago.

I'd suggest that Google will make short work of searching the archives
of this list to find the answer.

In parted on a GPT disk, the boot flag identifies an EFI system

flag (with parted, not fdisk) and check whether the system can boot again.

parted /dev/sda set 1 boot on



As I explained elsewhere, it now boots without problem.
But the gtp remains exactly as on above with no boot flag

Why do you think it tries to boot from a network?

Because it is displayed.

Again, I don't think filing a bug without any info but it doesn't

work will get your problem solved.


I am not able to find the bug myself. I am ready to spend hours to fix
it, but I need the help of someone to tell me where to search...

I think we got a differing understanding here. I think you just
encountered a bug, or you did something really stupid, which shouldn't
happen if you sanely try to install Debian. We got to describe the bug
now, so it can be fixed.
If some software let its user make someting really stupid, the problem 
is not with the user but with the software. And after 40 years in 
computing and a full week in trying to install jessie, I know I can have 
done someting stupid. But there is too some probability that there is 
some bug in grub...

So, as you say, the point is to well describe it.


Now my solution attempt, it worked for me once (but like 3 years ago)


# fdisk /dev/sda


Thank you, anyway fdisk cannot be used, I must use parted.
And I need the solution at long term, I cannot accept a that next 
aptitude upgrade breaks my boot...

Re: Debian sur ACER Travelmate ne boote pas

[Pierre Couderc]

Merci, la réponse est que dans la doc officielle, il est écrit qu'il 
faut passer par wheezy pour installer sid...
Je ne connaissais pas cet installer, je vais essayer mais je suis 
inquiet de  prendre le risque que mon PC brutalement ne veuille pas 
démarrer un jour de mise à jour.


J'essaye et rendrai compte.

J'ai compris ce qui se passe.
L'installation sous wheezy se passe bien.
Je boote et je reboote sans problème.

Puis, je fais une migration à jessie (en suivant les instructions

Une migration sur un serveur, avec beaucoup de configuration..., 
encore passe, mais là, une install from scratch,  sur un portable, 
pourquoi pas directement avec l'installeur jessie 
https://www.debian.org/devel/debian-installer/index.fr.html ? Avec 
toutes les modifications y compris dans le démarrage (systemd...), je 
ne vois pas l'intérêt de passer par une installation wheezy suivie 
d'un upgrade.


Bonne soirée,

boot fails on jessie on Acer Travelmate

[Pierre Couderc]

Hello

I have a problem with  jessie : my Acer Travelmate (P253) refuses to boot.

I have used 2 methods :
1- install wheezy, all is ok, I boot and boot again.  I change it to 
jessie (following standard instructions) : I can boot no more
2- I have used net installer debian-jessie-DI-b2-amd64-netinst.iso . 
Same problem.


There is no message, but it seems that the HDD is not seen and the PC 
tries to boot on the network.


I have repeated many times the problem, so I suppose it is not a mistake 
of mine.
I think that it did boot correctly with wheezy, but a regression in 
jessie creates the problem.


1- what am I missing ?
2- if it is a bug, in what package should I declare it ?

I am willing to help to fix the bug, if any.

Thank you in advance

Pierre Couderc

This may not help at all because things may have changed in the last
couple of months, but I'll give it a larrup.

I don't know what the standard instructions are?

This is exactly what you say above.


If you can install wheezy with a minimum install, no packages other
than what you need to get a bootable system, and you're doing a net
install.
I did that : only standard utilities. Boot  and reboot, and rereboot to 
be well sure.

By only installing the minimum packages on the install of wheezy, you
don't get a lot of stuff left behind from the change to jessie.

On the reboot ***after*** removing the CD/USB stick or whatever, just go
into your /etc/apt/sources.list and change every instance of wheezy to
jessie.

I did that.

Save the file and the do an apt-get update  and  apt-get upgrade. When
this is complete and everything is configured.
I did that. But I had to repeat the upgrade operation many times until I 
get a clear system with no more packet loaded with the last upgrade.



  Reboot.

:(

Should then be fine.

:(   :(


Like I say: if nothing has changed in the last couple of months since I
installed a jessie system on a clean machine. This way has always worked
for me in the past, but your mileage may vary.
As I imagine this has been tested thousand times in the world , I thnk 
this may be a problem due my particular computer.
And I would like to report it as a bug. But I do not know in which 
package : grub-common ?

Strange indeed.



Thank you Charlie,
But as I did all on correctly - I hope -, I think that this is a bug 
linked to my own computer.

So I want to declare it and my question is : where ?
If I get no better  answer, I sall declare it in grub-common

Sent this to Pierre's private mail first. Sorry.

Hi Pierre,

you might want to dig further into this,

Mmm, what is my other choice ? W8 ?  Ubuntu ?
as I can't see how a developer could fix the error you are 
experiencing without more information.

But I am ready to spend hours to fix that !
Wht is needed ?
Have you tried chrooting into the unbootable system from an install 
cd's rescue mode? Is there anything suspicious in the logs?

Yes, I can read files from a mive CD. What log shold I search ?


When exactly does the boot-up stall? You don't even see the GRUB menu, 
do you?
I am not sure what is the grub menu, but if it is the blue menu asking 
which debian version to load. I do not arrive there.
In fact, it seems  to me that the disk is not read, but it tries to net 
boot.


Have you tried with another boot loader? Last time I installed, LILO 
was still available for selection from expert install iirc. If the 
system boots with LILO, you would have narrowed down the problem quite 
a bit.
No, sorry, I am not enough expert. If this is a regression in GRUB, it 
must be solved, one way or another.
Debian wheezy works fine on this computer. Jessie has worked too, but no 
more today.


If you do get to GRUB but booting fails afterwards, you can try adding 
debug flags to your kernel options, see:
https://wiki.archlinux.org/index.php/boot_debugging This link is for 
Arch, so be careful, not every last bit also applies to Debian, but it 
was the most comprehensive guide I could find now.
I do noth think I go up to grub, but I thnk that something is grub 
broken by the installation of jessie.


Again, I don't think filing a bug without any info but it doesn't 
work will get your problem solved.


I am not able to find the bug myself. I am ready to spend hours to fix 
it, but I need the help of someone to tell me where to  search...


Thank you Simon
PC

Debian sur ACER Travelmate ne boote pas

[Pierre Couderc]

Bonjour,

J'ai un problème en installant une debian sur un Acer Travelmate (sans 
aucun OS alternatif).
J'ai fait une installation minimum (laptop, utilitaire système), après 
avoir désactivé le boot EFI (Legacy Bios).

Et il refuse de booter.

Il passe en :

grub rescue 
en déplorant l'absence de /mnt/boot/grub/i386pc/normal.mod

En bootant avec un CD live, le disque a une bonne tête, avec une 
arborescence semble-ril normale.


Merci pour votre aide.

Le /mnt me fait légèrement tiquer...



Ben, moi  z'aussi !
J'ai essayé de réinstaller en ayant tout effacé, y compris la GPT, et 
sans l'empêcher cette fois de créer la partition UEFI.
Dans ce cas, il ne boote pas sur le disque et essaye de booter sur le 
réseau (legacy boot ou UEFI boot)...


Je galère depuis deux jours à essayer d'installer un système bootable, 
UEFI ou non.

Mais c'est possible car j'ai déjà réussi une fois sur ce PC.
Je me demande s'il n'y a pas des instabilités dans grub.

Question candide :

Merci

- je vois ACER TRAVELMATE et boot UEFI désactivé.
- je vois ...grub/i386pc/...

Je me pose la question d'un PC sous 32 ou 64 bits ?
 UEFI = machine moderne sous 64bits.
 i386 = veille machine sous 16/32bits.

Peut-être rien à voir avec tout cela, sorry pour le bruit dans ce cas.


Mmm, cela à peut-être à voir.
Il s'agit d'une machine moderne 64bits. Mais je ne sais pas booter en 
UEFI un CD debian, donc je l'ai booté en legacy BIOS.
et je l'ai installé en modifiant manuellement pour supprimmer la 
partition UEFI qu'il avait tendance à me rajouter.

C'est là que j'ai eu ce message.
Puis j'ai retenté une install en le laissant mettre sa partition UEFI 
mais là il n'essaye même plus de charger sur le DD (legacy BIOS  ou UEFI).

J'ai réussi à installer en UEFI de base. Je n'ai pas compris pourquoi 
j'avais échoué précédemment, mais ça a l'air de fonctionner...
