You too can run containers on your Ubuntu!
Trying out LXD containers on our Ubuntu. This post is about containers, a construct similar to virtual machines (VM) but so much lightweight that you can easily create a dozen on your desktop Ubuntu! A VM virtualizes a whole computer and then you install in there the guest operating system.

I might write a few more articles on LXD. If you have any suggestions for improvement, I would be glad to hear them. In addition, is the blog theme good enough for such tutorials?

Hey Everyone. I've run into an interesting snag and I'm wondering if anyone could give me a hand.

My ideal server for my house would be Ubuntu Server 16.04 with a Cinnamon front end. I started down that road and got server installed and started installing cinnamon and Mate (just for options) but then when I went to install xorg I'm getting a "Server terminated with error (1)."

I"m able to start x from root but not as a user. I know it's a permission issue, but I can't, for the life of me, figure out what it might be. Any thoughts? What would you like me to pull for you?

Thanks guys. I finally decided that because my end result was to be an Ubuntu install without the bloat of unity so I just installed ubuntu mate and added cinnamon. It would have been fun to figure it out with server, but if rather get on with rebuilding my htpc. I have about 4 T of content to move, scripts to migrate, and applications to install and configure. Life's too short to muck with xorg. Thanks again!

Just finished a week long course on OpenStack. It was very cool! The labs were all hosted on Ubuntu servers, although they used Yum instead of apt for package management. We talked a little bit about DevStack for a home lab. Anyone have experience with DevStack? Also, has anyone migrated virtual servers from VMWare esxi 6.0 to DevStack? I'm trying to decide if I want to migrate my homelab network management tools and virtual servers off VMWare over to DevStack, or maybe pick up an additional PC for the lab. Ultimate goal is to try to go to virtual network hardware rather than vendor specific hardware (i.e. shut down my Cisco router, spin up VyOS or some other virtual router, shut down my Cisco switch, but a multi-port NIC in my PC and spin up a virtual switch, maybe play with a virtual firewall for fun).

Thinking this over, it's KVM I want for Network Virtualization (a couple pieces of virtualed network gear in a white box) and OpenStack I want for Server virtualization. So time to grab more hardware for different types of virtualization depending on purpose and goal.

I know that many do not like whatsapp, but it is the most important application that is missing on Ubuntu touch, many people in fact do not buy Ubuntu phone precisely because of this lack. Here there is a direct petition to Mark Zuckerberg to create a version for Ubuntu Whatsapp touch. the votes are progressing well in a short time, also supports you with a signature!

Guys there is a way to setup full HDD backup without the need to use the live CD solutions? I need to make it simple since it's for my dad... I already use the included backup solution dejadup but I want something I just could restore back like an image. Does the snapshot works in my case? If so any good tutorial about it? Thanks in advance to all... cheers ^^

Or ZFS snaps. You should also copy to removable media in case the drive fails

[SOLVED]
Adding a swap file solved it.

Hi again.
I have some major issues with Ubuntu 16.04 on my laptop. I have problems with Nautilus (posted here earlier), Gedit (takes a lot of time to open) and now on Inkscape.
Someone else has these issues?

I'm trying to do a survey of how people feel about their OS for a project (trying to include as large of a sample size as possible with advanced and not advanced users alike). Would that be okay/appropriate to share here?

I don't believe this has been shared here previously, so anyone fancying having a crack at LXD, ZFS and bridged networking, this guide is for you!
LXD works perfectly fine with a directory-based storage backend, but both speed and reliability are greatly improved when ZFS is used instead. 16.04 LTS saw the first officially supported release o…

been seeing some pretty cool desktops lately and thinking about running my main system again. i just can't decide of the flavor.

i've been using ubuntu off and on since 7.10, but to keep up with my friends and gaming i've always had windows on my main computer, sometimes dual booting, currently not. since microsoft gave out free upgrades to win10 i've been sticking with it for awhile (i have 3 other machines on ubuntu though)

since i'm not an avid gamer anymore and all the games i still play have a gold or higher rating on PlayOnLinux, i'm thinking of dropping windows all together

TL:DL - what flavor are you using and why? what advantages do you see with it?

Ubuntu performance fine tuning

Applications have different characteristics. Parts of a binary typically can be swapped out to leave more memory for data. Inmemory databases, like memcached should never swap out.

PostgreSQL, MySQL, MariaDB heavily make use of memory buffers, which become pretty useless, when your database is much larger than available memory. Double buffering (database own buffers) and Linux kernel buffering accesses to database file itself - is pretty useless.

Every VM can run identical binaries. Linux supports Kernel Samepage Merging. So, 20 identical Apache binaries share same code. In that case, swapping dramatically decreases performance of 20 virtual machines (or containers) at the same time.

Mobiles, looking up mobile web pages over bandwidth limiting carriers, causes TCP/IP buffer size to dramatically increase. Setting TCP/IP connection timeout, lowering TCP/IP buffer size (per connection), helps.

High loads typically cause SSH login delays. Administrative access feels unresponsive. Rising priority for certain ports, short packages solves this Linux specific problem (FreeBSD hasn't!).

Game servers typically require kernel realtime patches for reducing latency.

Running hundreds of fully virtualized machines, e.g. KVM on many cores finaly require setting different parameters, depending on load characteristics. Same for running thousands of Linux containers. Depending on VM and container namespace, Linux allows to set parameters individually for each VM/container.

Some CPU's have direct connection to network cards, others only indirect. Pinning network I/O intense processes to these hardware preferred CPUs (and interrupts) can dramatically increase performance.

SSD drives typically show very low latency and high IOPS. Optimizing for that is ok. When most IO are read accesses. When only a single process keeps on permanent writing to file system (longer than 20 seconds), performance of SSD untypically collapses, leading to performance far below magnetic drive. Reason: SSD RAM write buffers saturated. Same for SSD drives, that tend to "full". Leaving more than ⅓ free on FLASH drive helps.

... and, and, and ...

Have fun!

I don't know but my Ubuntu 16.04 give me a lot of problems during installation and updating. The previous versions are very stable but 16.04 is very Buggy and in-complete.

I install mint 17.3 but my system does not respond then I install Ubuntu studio 14.04 but the software centre doesn't update. I really love Unity that's why I cant leave Ubuntu because unity is not provided and supported by other distros officially
