Everyone, please welcome my daughter Diana into the world.

She arrived at 7:26am today!

This guide assumes you already have a running Ubuntu 15.10 system on which you want to configure Xen Orchestra, everything else is documented below.

TL;DR: Run this command as root on Ubuntu 15.10...

sudo curl https://raw.githubusercontent.com/scottalanmiller/xenorchestra_installer/master/xo_install.sh | bash

During the installation of your OS, you'll want to create a user outside of root, I made my user account xoadmin

How to Install Xen Orchestra Source on Ubuntu 15.10 (self compiled) AKA MANUAL installation

sudo apt-get install --yes nfs-common
curl -sL https://deb.nodesource.com/setup_5.x | sudo -E bash -
sudo apt-get install --yes nodejs
curl -o /usr/local/bin/n https://raw.githubusercontent.com/visionmedia/n/master/bin/n
chmod +x /usr/local/bin/n
n stable
node -v
npm -v
sudo apt-get install --yes build-essential redis-server libpng-dev git python-minimal
git clone -b stable https://github.com/vatesfr/xo-server
git clone -b stable https://github.com/vatesfr/xo-web
cd xo-server
sudo npm install && npm run build
cp sample.config.yaml .xo-server.yaml
nano .xo-server.yaml

#Edit and uncomment it to have the right path to XO-Web, because XO-Server embeds an HTTP server (we assume that XO-Server and XO-Web are on the same directory). It's near the end of the file:
#  mounts: '/': '../home/xoadmin/xo-web/dist/
#  save and exit

cd ~
cd ../xo-web
sudo npm i [email protected]
sudo npm install
sudo npm run build
cd ../xo-server
sudo npm start

The scripted installation thanks to @scottalanmiller

Github Repo

Below is the preferred Installation method. It includes the systemctl xo-server.service written by @Danp

sudo bash
<password>
sudo curl https://raw.githubusercontent.com/scottalanmiller/xenorchestra_installer/master/xo_install.sh | bash
<password>

In your favorite web-browser go to this VM's IP Address, login with the default user: [email protected] and "admin" for the password. Update your Login Details!!

Add your Xen Server(s) and go to town.

Automatically Start XO at Boot - See this Post by @Danp Also copied below.

Create a file in /etc/systemd/system/xo-server.service and enter the below into it.

# systemd service for XO-Server.

 [Unit]
 Description= XO Server
 After=network-online.target

 [Service]
 WorkingDirectory=/opt/xo-server/
 ExecStart=/usr/local/bin/node ./bin/xo-server
 Restart=always
 SyslogIdentifier=xo-server

 [Install]
 WantedBy=multi-user.target

Save the file, and then run to enable the service at start up.

sudo systemctl enable xo-server.service

To monitor the service you can then run

journalctl -u xo-server -f -n 50

For everyone on the newer releases of the "stable build" at least as of April-8-2016 there appears to be a bug when attempting to mount an NFS share; to resolve this follow the short process below

• Login to your XO web console
• Go to Backup
• Select Remote Stores
• Add your NFS Share, it'll likely fail out(unless it's been fixed since this posting)
• Back on your XO console go to /tmp/xo-server/mounts
• Run "ls" to see what mount is listed on your server
• Next run "mount -t nfs nfs-server-ip-address:/path/to-share remote-#"

Replacing nfs-server-ip-address with the actual IP of the remote server and the remote-# with whatever is listed on your console.

Any suggestions?

Tell your CFO to stop giving tours of your server room and focus on saving money for more important things.

Since Scott is our resident expert on said topic, I figure here would be as good a place as any to post SW articles regarding IT people who are in a position where they are unknowingly building an IPOD.

@BradfromxByte thank you for dealing with all of the back and forth and kick ass servers.

@EddieJennings said in IBM Datapower on Linux:

I've never dealt with Datapower, but I suspect there's a configuration file related to datapower-control that may need some editing.

So there is a configuration file, but there is no reference at all within the conf file (/var/ibm/datapower/datapower.conf) regarding the LUKS partition.

@CCWTech I wish I had that monitor setup

As for getting everything to open on a separate monitor and with the content you had open I'm not sure of off hand. I only use two monitors... and all of my content is constantly changing.

@CCWTech said in How to get Chrome to remember which monitors to open on:

I am using Windows 11. This worked fine on Ubuntu but I needed to switch to Windows in order to support other apps.

Maybe I am asking too much but I have 4 screens. I have Chrome open on each screen and about 8 tabs open on each screen.

But, when I reboot, Chrome remembers the tabs I have open, but puts them all on one screen and I have to then re-arrange each time. It's quite a pain, especially with how often Windows makes you reboot.

Is there anything I can do to get Chrome to open as I want it to?

Are your monitors selected as Primary and Secondary, right click on the desktop, Display Settings.

If you want your "right" monitor to be the primary, change it so it is and then move Chrome to that screen. Close it, and reopen to see if the issue is fixed.

Does anyone have any experience with Datapower on Linux?

Simply put, it should be an installation through RPM, which I have all of the RPM. What I'm getting hung up on is the LUKS partitions which are apparently required, but not specified what needs to be done to configure these.

From IBM:

Resource requirements on Linux hosts
To install the DataPower Gateway, the host must meet the following requirements.
To install the RPM packages, the host must be running a supported 64-bit version of Linux.
2 GiB of free storage must be available on /opt.
5 GiB of free storage must be available on /var.
At least two free loop devices are needed, with another loop device when RAID storage is used.
RAID storage, if used, must be configured in the datapower.conf file.

I'm not using raid, here I'm showing the disk layout and the loop devices.

The installation which is a simply yum install xxx.image.x86_64.rpm xxx.common.x86_64.rpm

Which I then should have a stopped "datapower.service", but the service keeps crashing because it's looking for these LUKS partitions.

I still say it could have been avoided if CrowdStrike had tested the change on a single device prior to releasing it publicly. It could have been a simple automated test as part of their release pipeline.

Even a better rollout strategy could have prevented it from going too far.

What's funny is that CS is now saying that they have decided to start testing their releases with the use of "besides showing interest in working with Microsoft to work on the “kernel-level restrictions” development, is also taking a new approach to certify each new sensor release through the “Windows Hardware Quality Labs."

Whats also funny is that if you look at almost any open source software of similar caliber, they do all that stuff in their build and release pipelines or other work flows before public releases.

Exactly!

@dbeato Yeah it does it has a webpage that is native to the solution. I don't know that it's optimized for mobile, but I doubt it.
