I need to create a 16.04 LTS Server qcow2 image with some modifications. Questions: What is the best way to do this? Is it possible to do with python-vm-builder? Please show how.

I have built a 16.04 LTS qcow2 image with python-vm-builder, but KVM says it doesn't contain an operating system. What could be wrong?

I need to build a 16.04 qcow2 image. I could really use some help on this

Can VMbuilder create a 16.04 image?

When I try to install python with Conda I get:

/opt/conda/pkgs/python-3.5.1-0/bin/python: error while loading shared libraries: libpython3.5m.so.1.0: cannot open shared object file: No such file or directory

What should I use instead?

Is vmbuilder deprecated?

@Rinzwind Ok, thanks

If I install samba4 on Ubuntu server, does it start automatically when I reboot or do I have to do something?

It's running Ubuntu Server LTS

@Albas I thought the ineq. sign should only be reversed when I divide or multiply with a negative number

macurie

Feb 17, 2016 13:10

@Albas Yes, but I can't see how to get $\frac{1}{\epsilon}-1\le 2n$

macurie

@TobiasKildetoft

macurie

Feb 17, 2016 13:08

But I know that the inequality sign should be reversed

macurie

Feb 17, 2016 13:08

I get $2n\le\frac{1}{\epsilon}-1$

macurie

Feb 17, 2016 13:07

Sorry, I meant $|\frac{1}{2n+1}|\le\epsilon$.

macurie

Feb 17, 2016 13:06

I have problems solving for $n$

macurie

Feb 17, 2016 13:05

Sorry, I meant $|\frac{1}{2n+1}|\le\epsilon$.

macurie

Feb 17, 2016 11:34

@TobiasKildetoft So I should just draw it as dots approaching 0 from 1?

macurie

Feb 17, 2016 11:27

@TobiasKildetoft I mean how would one sketch it?

macurie

Feb 17, 2016 11:26

What does the set look like?

macurie

Feb 17, 2016 11:26

What does the set $\{\frac{1}{n}|n\in\mathbb{N}\}$ on a number line?

macurie

Feb 8, 2016 12:58

It's the first one I'm worried about

macurie

Feb 8, 2016 12:57

Is it correct to pronounce $a\ge b$ as "a is greater than b" and $a>b$ as "a is strictly greater than b"?

macurie

@Semiclassical Thanks!

macurie

Jan 25, 2016 20:58

yes

macurie

Jan 25, 2016 20:57

@Semiclassical Sorry but I don't follow the last part of the argument

macurie

Jan 25, 2016 20:36

How can I do that?

macurie

Jan 25, 2016 20:33

@Krijn Yes, but I want to prove it with sumbols

macurie

Jan 25, 2016 20:19

Let $x\in\mathbb{N}\Rightarrow$ be even. How do I prove that "x^2 is odd" ==> "x is odd" without proving the contrapositive?

@prive hi

I meant "let $U$ be a subspace in $\mathbf{R}^n$".

macurie

Jan 22, 2016 21:25

w again?

macurie

Jan 22, 2016 21:25

Let w be a vector in $\mathbf{R}^n$ and $U$ be a subspace in $U$. Let $w\in U$. What do I get when I project w onto U?

macurie

Jan 21, 2016 15:47

I think you mean $\vec{a}$ :)

Jan 21, 2016 15:42

Should I use superscript arrow or bold for vectors?

macurie

Jan 21, 2016 15:41

@Huy Thanks

Jan 21, 2016 15:39

How do I express that two vectors $u$ and $v$ in $\mathbb{R}^n$ are not null vectors?
