Of course. You've asked it to couple the display with its embedded VNC 
server. You'll need to connect with a VNC client to see it.

The parameters you used look fine. Display ":0" should translate to TCP 
port 5900, meaning that qemu should be listening on port 5900. You can 
check with netstat or ss.



2) What "vncviewer" or "vncconnect" parameters do I use to get to the
qemu session?


Assuming both server and client are run locally, connecting to either 
"localhost:0" or "localhost:5900" should work.




   I just had a scary thought... the vnc "help" mentions connecting to

In portage's defense, the symbol used is not really mathematical
notation, it's an operator used in code, and only in code.

We do this lots:

* is multiplication
^ is exponentiation
% is modulus (sometimes just mod)

and several more, all driven by the lack of appropriate symbols on early
ASCII keyboards (and the majority of current keyboards...)

I would probably have selected "/" as well if I were the implementer,
but that's because I heavily resist using backslash for anything other
than escapes. My brain usually will not let me go against this one...

I'll look into those, but do take note those books are 14 and 18 years
old - that's eternity in our world.

Basics never change, details do. Some features are here for the long
haul and I doubt anything will really change them: pipes, named pipes,
unix sockets and things of that ilk. The real bugbear with IPC is people
reinventing the wheel over and over and over to do simple messaging -
writing little daemons that do very little except listen for a small
number of messages from localhost and react to them.

Use a generic message bus for that! It fits nicely in the grand Unix
tradition of do one job and do it well, and few apps have passing
messages around as their core function. Hand it off to the system,
that's what it's there for.

One day I might well do an audit of a typical server base system and
count all the apps that have a hidden roll-your-own message process in
place. I'm certain the results will be scary.

I was also surprised to see `/'.  A part of me was going to send about
quotient groups (the normal usage of '/') but I managed to refrain
myself.  However, now that willie has opened the door ...

/ is normally used for quotients.  For example, if we take the group Z
of integers under addition and the subgroup 2Z of the even integers,
then Z / 2Z is the quotient that results from taking Z and identifying
all the elements of 2Z.  So in Z / 2Z, all the even integers are zero
and hence all odd integers are equivalent (since they differ by even
integers, which are zero).  Thus the quotient has only 2 elements and is
the familiar group Z2, the integers mod 2.

The above can be generalized.

I know, let's do all process-scheduling in user-space, I mean who needs 
preemptive
multi-tasking when we have such experts in the early userspace at our disposal.
User-land threading works really well too: so long as we worship at the altar of

systemd *is* udev; they are the same package. Uninstall the Gentoo
packaging of udev (which basically strips systemd), install systemd,
and it includes the official udev.

looks like both openrc and systemd should depend on baselayout, so

You can rewrite (A \\ B) as (A && !B), giving you one less case to worry
about.

But, some people (most notably, programming languages) assign a higher
priority to intersection (&&) than they do to union (||). Of course,
mathematically, they should probably have the same priority, so many
people do the left-to-right thing.

So in practice, you'd better use parentheses if you want anyone to know
WTF you're talking about.

Hi,

Do you have baselayout installed? /etc/profile should be included in  
baselayout.




Thanks, I had to reinstall baselayout (2.2). I wonder which package  
(systemd?) has removed /etc/profile

Hi,

Hi,

previously and still documented nearly everywhere

one has to do

env-update
source /etc/profile

after chroot

but in recent systems, the file /etc/profile is gone.

How to adapt the environment in a new system?

There are a few bugs regarding this issue, for example: 472938, 476992 and 
477214. If I understand things correctly, all installed modules are enabled, 
but they're loaded "on-demand" (I guess this means the first time they're 
used, but I'm not sure). The way suggested in one of these bugs to have a 
working autocompletion is to source /usr/share/bash-completion/bash_completion 
from you .bashrc file.

I think it's the former. But I've been known to be wrong on things
(lately, more often than not...)

Just looked on The Google, and there's no consensus I can find. Best
advice seems to be that union and difference are equal precedence so the
expression is evaluated left to right.

Hence it's the former :-)

Is the problem with reading the module file or loading it? If you
modprobe the kvm module as root first, can you then run it as a user? You
may want to add the module to /etc/conf.d/modules.

I can't think how intersection could be generally useful in portage

I have:

"binary" USE flag set for upstream compiled binaries
...

using the binary USE flag (upstream compiled)
*  app-emulation/qemu

...

and kernel 3.10.1

It's standard mathematical set operators. In maths, a set is defined as
"a collection of well-defined objects". Sets have no dupes.

http://en.wikipedia.org/wiki/Set_%28mathematics%29
http://en.wikipedia.org/wiki/Set_theory

Sets have several well-defined operations that can be done on them:
union, intersection, difference plus a few others.

@set1+@set2/@set3 reduces to:

all the elements of set1 and set2 without the elements that are in set3
(/ is difference).

As an example, assume portage ships two sets @kde and @kdedev:

@kde
  kdeadmin-meta
  kdebase-meta
  kdemultimedia-meta
  kdepim-meta
  ...

@kdedev
  kdewebdev-meta
  kdebindings-meta

However, kmail sucks and akonadi sucks moar, so define for yourself

@suckykde
  kdepim-meta

And add to your world sets:

@kde+@kdedev/@suckykde

effectively giving you kde without kde-pim.
Without operators, you have to copy-paste an existing set and maually
remove the entriess you don't want.

Useful, not so?
Well, it all gets extremely murky very very quickly. Portage applies
more than just mathematical sets, there's this concept of deps that are
not part of set theory.

What if something in set1 has a dep, and that dep is listed in set3 and
must be removed. To resolve this, you must have precedence rules and
must ignore something. You either ignore set3 and install anyway, or
throw a blocker and say the item is required in set1.

Either way there's no clean way to do it and lots of users are going to
get annoyed. Not to mention the extra bug reports

What does that mean? set1 and one of set2 or set 3? Or both set1 and set2
or set3 only? I'm not sure how this would be useful but I can certainly
see how it would cause confusion and problems, but I hadn't heard if it
before.

Wow thats intresting. What could the / operator possibly do in the case
of sets?

you've been using it for years, it has gone through 186 alpha versions
and before that just over 100 pre versions. You never had a problem with
it. Neither has anyone else really.

So what are you worried about again?

Just pretend that "alpha" isn't in the name and it isn't masked -
effectively that is actual status - last I heard from Zac there is one
or two odd edge cases that still aren't 100% right, but few people ever
run into them. You are highly unlikely to be one of those few people.

[gentoo-user] Portage 2.2

[Pavel Volkov]

What is the status or portage 2.2?
It takes so long to get out of alpha. Has anyone here had any serious
problems with it? I've been using it for a a few years without any
accidents. Just wondering if I should be prepared for the worst.
I also remember reading in Changelog that 2.2 remains masked until 2.1 gets
enough testing, that was ages ago.

It initially suported set arithmetic (you could writes expressions like
"@set1+@set2/@set3"), I wonder why it was dropped :)

[gentoo-user] QEMU setup questions

[Walter Dnes]

  So I emerged QEMU, which pulled in some dependancies.  Things are not
going well...

1) The following warning shows up in elog...

> WARN: pretend
> You have decided to compile your own SeaBIOS. This is not supported
> by upstream unless you use their recommended toolchain (which you are
> not).  If you are intending to use this build with QEMU, realize you

> Virtual machines subtly fail based on changes in SeaBIOS.

  I don't see any USE flags about this.


2) I download a Gentoo install ISO, and create a 7 gig raw file sda.raw,
and start qemu-kvm

$ qemu-kvm -hda sda.raw -cdrom installx86.iso -boot d
Could not access KVM kernel module: Permission denied
failed to initialize KVM: Permission denied

but... but... but... I am a member of group "kvm".


3) su to root and retry to start QEMU

# qemu-kvm -hda sda.raw -cdrom installx86.iso -boot d
qemu-system-x86_64: pci_add_option_rom: failed to find romfile "pxe-e1000.rom"
VNC server running on `127.0.0.1:5900'

So root has sufficient permission, but there's a problem with the BIOS,
possibly related to item 1) above

Note; I can run as regular user, either of the 2 commands...
$ qemu-system-i386 -hda sda.raw -cdrom installx86.iso -boot d
$ qemu-system-x86_64 -hda sda.raw -cdrom installx86.iso -boot d
This doesn't run into permission problem 2), but still runs into the
rom not found problem 3).

4) At least VNC is running.  I emerged tigervnc and tried it

$ vncviewer 

TigerVNC Viewer 64-bit v1.2.0 (20130723)

X_ChangeGC: BadFont (invalid Font parameter) 0x0

...and the dialog box is all blanks, presumably because of the missing
fonts.


  I had QEMU working a few years ago, and I don't remember running into
all these problems.  What gives?

you forgot that shared library nonsense. Every app should just bundle
static copies of everything it needs and leave it up to the dev to deal
with bugs and security issues

Yes, lets have lots of IPC mechanisms instead of one daemon that handles
IPC for everything. While we're at it, let's get rid of syslog and add
file logging code to every program that needs it. cron and at seem a bit
of a waste of space too.
