  • Tomcat + Spring + CI workflow

    - by ex3v
    We're starting our very first project with Spring and java web stack. This project will be mainly about rewriting quite large ERP/CRM from Zend Framework to Java. Important factor in my question is that I come from php territory, where things (in terms of quality) tend to look different than in java world. Fatcs: there will be 2-3 developers, at least one of developers uses Windows, rest uses Linux, there is one remote linux-based machine, which should handle test and production instances, after struggling with buggy legacy code, we want to introduce good programming and development practices (CI, tests, clean code and so on) client: internal, frequent business logic changes, scrum, daily deployments What I want to achieve is good workflow on as many development stages as possible (coding - commiting - testing - deploying). The problem is that I've never done this before, so I don't know what are best practices to do this. What I have so far is: developers code locally, there is vagrant instance on every development machine, managed by puppet. It contains the same linux, jenkins and tomcat versions as production machine, while coding, developer deploys to vagrant machine, after local merge to test branch, jenkins on vagrant handles tests, when everything is fine, developer pushes commits and merges jenkins on remote machine pulls commit from test branch, runs tests and so on, if everything looks green, jenkins deploys to test tomcat instance Deployment to production is manual (altough it can be done using helping scripts) when business logic is tested by other divisions and everything looks fine to client. Now, the real question: does above make any sense? Things that I'm not sure about: Remote machine: won't there be any problems with two (or even three, as jenkins might need one) instances of same app on tomcat? Using vagrant to develop on php environment is just vise. Isn't this overkill while using Tomcat? I mean, is there higher probability that tomcat will act the same on every machine? Is there sense of having local jenkins on vagrant?

  • VM can't ping LAN name but sees it via nslookup

    - by amphibient
    I am trying to connect to a network resource from my 10.04.4 VM (VMware Fusion) but the destination is unreachable by name. What is weird is that the name is visible in DNS: >nslookup my.name Server: 123.45.67.89 Address: 123.45.67.89#53 Non-authoritative answer: Name: my.name Address: 10.20.30.40 I can reach it (via ping) by the IP address (10.20.30.40) but not the name and I thought that was weird because the DNS clearly resolves the name. What can I do to enable access to this resource via the name?

  • Friday tips #2

    - by Chris Kawalek
    Welcome to our second Friday tips blog! You can ask us questions using the hash tag #AskOracleVirtualization on Twitter and we'll do our best to answer them. Today we've got a VDI related question on linked clones: Question: I want to use linked clones with Oracle Virtual Desktop Infrastructure. What are my options? Answer by John Renko, Consulting Developer, Oracle: First, linked clones are available with the Oracle VirtualBox hypervisor only. Second, your choice of storage will affect the rest of your architecture. If you are using a SAN presenting ISCSI LUNS, you can have linked clones with a Oracle Enterprise Linux based hypervisor running VirtualBox. OEL will use OCFS2 to allow VirtualBox to create the linked clones. Because of the OCFS2 requirement, a Solaris based VirtualBox hypervisor will not be able to support linked clones on remote ISCSI storage. If you using the local storage option on your hypervisors, you will have linked clones with Solaris or Linux based hypervisors running VirtualBox. In all cases, Oracle Virtual Desktop Infrastructure makes the right selection for creating clones - sparse or linked - behind the scenes. Plan your architecture accordingly if you want to ensure you have the higher performing linked clones.

  • How do I allow a standard user to update the kernel modules for VMware?

    - by GUI Junkie
    I've set up VMWare Player for my wife. Every once in a while (notably after a kernel update), the VMWare Player needs to be compiled into the kernel. My spouse does not have su- activated (if anybody screws up the OS, it's going to be me). I'd like to give her permission to do this, but only for that program. Is this possible? Can it be done safely (for the OS)? How can it be done? Edit: I tried to add the following to visudo guijunkette ALL=(ALL) NOPASSWD: /usr/bin/vmware-modconfig When running with her user, after typing her password, the following error occurred: So, in the end, no cigar. Edit: I've given up on VMWare Player and moved to VirtualBox. Made a clean install.

  • How to change the IP address on my Ubuntu virtual NIC

    - by DextrousDave
    I have a physical windows system, on which I run Vmware Workstation. Now on VMware I run Ubuntu 12.10. I am running a webserver on Ubuntu via LAMP, inside VMware. Problem: Now my local IP address for my virtual NIC (the one Ubuntu is using) has an address of 192.168.159.7, and my home router only issues IP addresses of the range 10.0.0.x. So if I want to port forward to the virtual NIC, which has a 192.168 address, I cannot, so my LAMP webserver cannot be accessed externally since the router does not know to send the packets on port 80 to the virtual NIC... How do I fix that? The only way I guess is to assign a 10.0.0.x ip address to the virtual NIC?? But how do I do that? I tried to do it on the host Windows machine with 'Get my IP address automatically' but it issues a 192.168 address every time... Thank you

  • Cann't find shared folder anymore

    - by SoftTimur
    I use VMware Fusion under Mac, and I have installed Ubuntu 12.04 and Windows 7 as virtual machine. Under Ubuntu, by "shared folder", I used to manage a common folder with Mac via /mnt/hgfs/myfolder. Under Windows, I have set up so that this folder is also accessible. But today I cann't find myfolder anymore under /mnt/hgfs in Ubuntu, while it is still accessible via Windows (and Mac of cause). I tried to restart the machine, reset the sharing settings, it still does not work. Could anyone help?

  • Compizconfig Grid doesn't work under Ubuntu as virtual machine

    - by SoftTimur
    I have installed Ubuntu as virtual machine within Mac. I have installed VM tools. The approach in this link of Compizconfig Grid, which worked in my previous laptop where Ubuntu was not a virtual machine, does not work anymore. I set some shortcut, but no action is launched... Does anyone know why? The major functionality I need from Grid is tiling windows to left/right side of the screen... Does anyone know any alternative?

  • Welcome to our Friday tips series!

    - by Chris Kawalek
    Today we're starting a brand new blog series. For your Friday afternoon reading, we'll be posting a technical tip or question and answer on a technical topic. We'll start by introducing ideas on our own, but we'd really like it if you were involved and asked us questions via Twitter! Tag your tweet with #AskOracleVirtualization and we'll consider your question for the blog. Today's tip is on Storage and Oracle Virtual Desktop Infrastructure: Question: I run Oracle Virtual Desktop 3.4.1 on Solaris and use a local ZFS storage pool.  How should I configure my ZFS ARC cache?  Answer by John Renko, Consulting Developer, Oracle: Oracle recommends about 5G of ARC cache per template in use to achieve up to a 90% disk read offload. Set your ARC min=max to reserve the maximum amount of your remaining memory for your running VMs. In /etc/system: set zfs:zfs_arc_min = 5368709120 set zfs:zfs_arc_max = 5368709120 The amount you need to reserve will depend on your template but this has proven to be a great start for a typical windows 7 VM running productivity applications.

  • No sound in 12.04 on VirtualBox

    - by john crisp
    No sound when installed in VirtualBox. When I boot from the live CD in Windows, sound works fine on my speakers. When in boot the live CD in VirtualBox it does not see my speakers. In sound properties only digital output built in S/PDIF and headphones! I've done the pavcontrol - alsamixer - all settings are OK. I've tried both 32/64 versions of Ubuntu. Running current version VirtualBox. System: Windows 7 64 - i5. What am I overlooking?

  • Regulating outgoing traffic on ubuntu VM

    - by DazSlayer
    I am making a virtual network setup for my high school cybersecurity team to practice. I am connecting all the VMs together through a VPN and then people who are practicing will VPN in and ssh/remote desktop into the different VMs. The problem is that for practicing, they will need root access into the VMs and because the VMs are connecting to my personal network, the VMs pose a security risk to my personal network. Is there any way in either VMWare or VirtualBox or even making an unchangeable iptable (I can make all the windows VMs go thru a linux VM) to prevent people from connecting to my local network via the VM?

  • New Project Starting. Got Gas?

    - by merrillaldrich
    “Storage is just like gasoline,” said a fellow DBA at the office the other day. This DBA, Mike is his name, is one of the smartest people I know, so I pressed him, in my subtle and erudite way, to elaborate. “Um, whut?” I said. “Yeah. Now that everything is shared – VMs or consolidated SQL Servers and shared storage – if you want to do a big project, like, say, drive to Vegas, you better fill the car with gas. Drive back and forth to work every day? Gas. Same for storage.” This was a light-bulb-above-my-head...(read more)

  • Ubuntu 12.4.1 failing in vm both Vbox and Vmware on new HP Envy 4t-1000

    - by Chas
    Brand new to Linux, getting frustrated trying to get an environment up with Ubuntu. My primary goal is to learn Linux and Apache/PHP development. I need to keep my Windows OS as main on my machine for work, so i'm trying to virtualize Ubuntu 12.4.1 without luck (many attempts). I have a new HP Envy 4t-1000 with 16gb ram, and 32 gb ssd caching with 500gb spindle hard drive. Graphics card is an Intel HD 3000 with AMD Radeon 7670M. With installing Ubuntu desktop in VBox, I'm getting this result: https://forums.virtualbox.org/viewtopic.php?f=6&t=51939 With VMware workstation 7 (patched), I complete the install of Ubuntu, it reboots, purple desktop briefly flashes then it drops to command line. I bought a beginning Ubuntu book, and it recommends trying to manually configure graphics if this happens. So I tried doing a safe boot holding shift - I get to the first screen (GRUB) loads fine, and I choose recovery mode. After choosing the recovery mode, I get the recovery mode options, and can arrow down to what the book suggests 'Run in fail safe graphic mode.' Once I select this option, I get a black screen with a large white dialogue box, at the top it says "The system is running in low-graphics mode. Your screen, graphics card, and input device settings could not be detected correctly. You will need to configure these yourself." Then there is an ok button way down at the bottom. When I select 'ok' I get a menu for a few options, book recommended 'reconfigure graphics.' When I try this, I get a menu of two options: 1) "Use generic (default) configuration or 2) use backup. I've tried both options several times, hitting ok just refreshes screen and nothing more. Rebooting at this point just goes back to command line as before. I don't know what to do at this point, I've spent too many hours this weekend trying in both VBox and VMware to get Ubuntu going. Isn't there like a very basic graphic display or something I can use to at least get into the desktop? I explored the GRUB some more, and tried to look at the startup and xserver logs - both are blank. No help there I guess? When I try to choose 'Edit the configuration file, then 'ok' screen just refreshes on same menu options, nothing happens. thx for any advice. I really need to focus on learning Linux, Apache and PHP, so perhaps Ubuntu just won't work on my hardware? Any other suggestions? I will need to virtualize - THANKS for any help/advice.

  • PCI hotplug doesn't seem to work

  • OpenStack + Ubuntu 12.04

    - by csgeek
    Supposedly openstack can be installed easily under Ubuntu 12.04 LTS. I've installed 32 and 64bit versions of Ubuntu Server with the same behavior. sudo tasksel check OpenStack hit Okay then I get a tasksel: aptitude failed (100) I've seen: http://www.hastexo.com/resources/docs/installing-openstack-essex-20121-ubuntu-1204-precise-pangolin and https://github.com/EmilienM/doc-openstack documentation, but I was hoping that since it was an LTS released and it was an option in tasksel that I was simply overlooking something obvious and it's just a matter of selecting the right checkbox and hitting okay. Too much wishful thinking?

  • VirtualBox install

    - by Chris
    I am using Win 7 Ultimate. I have the current version of Virtualbox. I downloaded Ubuntu 12.10 from the Ubuntu website and the install as disc image. Ubuntu probably goes thru about 75% of the install and then I get an error message saying that there is a hardware issue and cannot continue. The error message also says it cannot read the disc, etc, etc. I have downloaded 2 different versions of Ubuntu. I had downloaded and re-installed VirtualBox twice. I also tried 12.04 but came into the same issue. I downloaded the "desktop AMD-64" Thank you in advance for your help.

  • Why is "sudo virsh" hanging in the console?

    - by technophobia
    I wanted to experiment with OpenStack on my iMac: So I installed Ubuntu Cloud Live Image on a VM and I also ran DevStack on a fresh Ubuntu 64-bit Server VM. The DevStack script hangs on the following line: instances=`sudo virsh list --all | grep $INSTANCE_NAME_PREFIX | sed "s/.*\($INSTANCE_NAME_PREFIX[0-9a-fA-F]*\).*/\1/g"` I commented that block and ran the script again, this time it did not hang; thus completing its run. I attempted to run sudo virsh list --all on my CloudLive VM and it just hands until I break out of it. Why is sudo virsh hanging? Your help is appreciated. Note 1: The virsh command responds without sudo. Note 2: Not sure it matters, but I'm running my Virtual Machines in VMWare Fusion.

  • Can I virtualize a pre-installed Windows 7?

    - by SpashHit
    I am considering buying a new computer with Windows 7 (64-bit) pre-installed. Would it be possible to install Ubuntu (preferably 64-bit) dual-boot on such a machine, and then, using VirtualBox / VMWare, etc. under Ubuntu, make a virtual machine that "points to" the existing Windows 7 OS (without making a copy of it)? Just to be clear... at the end of this process: I would have a machine that dual-booted both Windows 7 (64-bit) and Ubuntu (64-bit). If I choose to boot Ubuntu, I would then have the possibility of running a visualization of Windows 7 within Ubuntu. There would only be 1 copy of Windows 7 on the hard disk.

  • Can I use my VirtualBox 3.* VMs with VirtualBox 4.0? If so, how come the repository doesn't have it?

    - by ximbim
    I had the following repository for virtualbox in my /etc/apt/sources.list: deb ttp://download.virtualbox.org/virtualbox/debian maverick non-free Then I found out there was a new version when I opened it today (the program prompted me with a window to manually download it from Oracle's site). Then I tried sudo apt-get update && sudo apt-get upgrade and got nothing. Here you have a way to add virtualbox-4.0 to your apt-get, but the problem is that it isn't updating, meaning I would have the two installed. I'm also worried if I'll have to do something like that each time it updates since that would defeat the point of apt-get. I've been using virtualbox with the apt-get update for more than a year now and this is the first time it has happened, so I was wondering if there would be a way to just update my current installation.

  • How to get VMware Workstation 8.0.4 work on Ubuntu 12.04 64 bit?

    - by user73987
    I've bought VMware Workstation 8 just today. After the installation I launched it and the application noticed me that "several modules must be compiled and loaded into the running kernel". During the process, VMware noticed me that was impossible to configure Virtual Network Devices and at the end, was impossible to start the services. The last message said that further information could be found at this address: /tmp/vmware-root-975001794/modconfig-22789.log So, I've pasted the content of the log message here. Can you help me or, rather, you suggest to wait for future updates of Ubuntu? My desktop environment is Unity.
