  • Multiple VM environment for developing/testing

    - by Hippo
    I was asked to create a setup for automated deployment, configuration, installation/updates of websites. A bunch of small websites will be bundled on one server. If more website will come up a new server will be created... I decided to us chef for this task. All servers will be running Ubuntu at the same version and configuration. The actual question: Everything needs to be tested properly before starting live deployment, so my question is: What is the best virtualisation tool to run multiple (5 - 10) virtual machines on a Ubuntu Laptop? Requirements: easy setup, fast (clone/snapshot of VMs) All VMs should be easily connected to the internet and should be able to communicate to each other (Open-Source / free would be great) So far I looked into: Virtual box is more for Desktop virtualisation, Cloning not possible, every new machine needs to be installed VMware Player Any suggestions? If there are any question about what I am doing please comment on this question, I will answer as soon as possible. This question is not about the actual set up, it is about a nice working environment.

  • Should I be able to Windows Phone 8 emulator running with this AMD config

    - by pete
    I have just bought a new system as follows * AMD A4-5300 Trinity 3.4GHz * Gigabyte GA-F2A55M-DS2 Motherboard I checked and the A4-5300 supports Virtualisation. I have run the SLAT checking tool and it says that my machine supports SLAT. Been into the BIOS and ensures that SVN is enabled. I have also run the coreinfo tool that indicates that SVN is not valid fort the machine nor is NPT.. not sure why this conflicts with the true BIOS setting (I checked with GIGABYTE and seems that NPT and NX are not options that can be set in the BIOS) But.. when I run the emulator I it hangs - I can see some activity in Hyper-V manager, but it doesnt get very far and no meaningfull error messages. Been working the plethora of suggestions to get around this, but so far, nothing has worked. My question is should this setup allow the WP8 emulator to run. I am positive the CPU supports virtualisation, but are there issues with the motherboard here? I have spent a huge amount of time on this so far....am I wasting my time with the current configuration, or should it work? thanks

  • Driver for Ensoniq AudioPCI ES1370 on Windows 7

    - by Matthew Steeples
    KVM is a virtualisation package for running operating systems such as Windows on Linux. Windows XP works fine in this, but Windows 7 fails to recognise the sound card. According to the documentation, the soundcard is a Ensoniq AudioPCI ES1370. Does anyone know where I can find a driver for this, or a compatible driver that will run under 7. I've not tried this in Vista as yet.

  • Cloud hosting for windows domain controller, possible?

    - by Preet Sangha
    We currently host our own domain controller (small company) locally on dedicated h/w. However to mitigate disaster recovery we're considering the use of virtualisation and cloud hosting. One thought is Virtual primary domain controller hosted in the cloud + a local (secondary) virtualised server running in the office as a cache? Is this possible or should I consider something else? We're happy to pay for the decent hosting and DR but this is really out of my experience.

  • How is a VM isolated from the physical host?

    - by dotnetdev
    Hi, I was thinking about virtualisation and how to explain it to a non-technical person and one of the things that I was wondering was how to explain the way that a VM is isolated and seperate from the phyiscal machine (so I can have a virus on a VM but this would never effect my physical host, right?). How does this technology work exactly? As I am a programmer, when I think of isolating processes, I think of using appdomains (I work with C# primarily). Thanks

  • High I/O latency with software RAID, LUKS encrypted and LVM partitioned KVM setup

    - by aef
    I found out a performance problems with a Mumble server, which I described in a previous question are caused by an I/O latency problem of unknown origin. As I have no idea what is causing this and how to further debug it, I'm asking for your ideas on the topic. I'm running a Hetzner EX4S root server as KVM hypervisor. The server is running Debian Wheezy Beta 4 and KVM virtualisation is utilized through LibVirt. The server has two different 3TB hard drives as one of the hard drives was replaced after S.M.A.R.T. errors were reported. The first hard disk is a Seagate Barracuda XT ST33000651AS (512 bytes logical, 4096 bytes physical sector size), the other one a Seagate Barracuda 7200.14 (AF) ST3000DM001-9YN166 (512 bytes logical and physical sector size). There are two Linux software RAID1 devices. One for the unencrypted boot partition and one as container for the encrypted rest, using both hard drives. Inside the latter RAID device lies an AES encrypted LUKS container. Inside the LUKS container there is a LVM physical volume. The hypervisor's VFS is split on three logical volumes on the described LVM physical volume: one for /, one for /home and one for swap. Here is a diagram of the block device configuration stack: sda (Physical HDD) - md0 (RAID1) - md1 (RAID1) sdb (Physical HDD) - md0 (RAID1) - md1 (RAID1) md0 (Boot RAID) - ext4 (/boot) md1 (Data RAID) - LUKS container - LVM Physical volume - LVM volume hypervisor-root - LVM volume hypervisor-home - LVM volume hypervisor-swap - … (Virtual machine volumes) The guest systems (virtual machines) are mostly running Debian Wheezy Beta 4 too. We have one additional Ubuntu Precise instance. They get their block devices from the LVM physical volume, too. The volumes are accessed through Virtio drivers in native writethrough mode. The IO scheduler (elevator) on both the hypervisor and the guest system is set to deadline instead of the default cfs as that happened to be the most performant setup according to our bonnie++ test series. The I/O latency problem is experienced not only inside the guest systems but is also affecting services running on the hypervisor system itself. The setup seems complex, but I'm sure that not the basic structure causes the latency problems, as my previous server ran four years with almost the same basic setup, without any of the performance problems. On the old setup the following things were different: Debian Lenny was the OS for both hypervisor and almost all guests Xen software virtualisation (therefore no Virtio, also) no LibVirt management Different hard drives, each 1.5TB in size (one of them was a Seagate Barracuda 7200.11 ST31500341AS, the other one I can't tell anymore) We had no IPv6 connectivity Neither in the hypervisor nor in guests we had noticable I/O latency problems According the the datasheets, the current hard drives and the one of the old machine have an average latency of 4.12ms.

  • How to handle many daily emails from cron efficiently?

    - by drumfire
    With each new server comes at least one more daily crontab email. The FreeBSD servers even send two: a daily and a security run output. Thanks to my obsession with virtualisation the number of emails I need to read (and then often discard without further action) is becoming too much. What ways are there to manage / automate this process? Can emails be replaced by something that is web based? Surely some of you must have found creative ways for this.

  • what are the components you can install on RHEL?

    - by user16654
    I just got a question from a customer(actually from a customer to my manager then to me) and he is asking the following question: What are the components that were installed with RHEL? It may sound like a silly question but to me it sounds vague. The main thing I am thinking about now is during install you can select three components: webserver software development and virtualisation. Could they be asking fro something else?

  • Thanks to .Net Developers Network in Bristol - Hyper-V for Developers slides not available for downl

    - by Liam Westley
    Thanks to the guys at .Net Developers Network (http://www.dotnetdevnet.com) for inviting me down to Bristol to present on Hyper-V for Developers.  There were some great questions and genuine interest, especially surprising for a topic that often has a soporific effect on developers. You can download the original PowerPoint file or the PDF complete with speaker notes from here, http://www.tigernews.co.uk/blog-twickers/dotnetdevnet/HyperV4Devs-PPT.zip http://www.tigernews.co.uk/blog-twickers/dotnetdevnet/HyperV4Devs-PDF.zip I should be back for DDD SouthWest (http://www.dddsouthwest.com).  You can get voting from Monday 29th March 2010, and for a change my proposed topic is not about virtualisation! Finally, apologies to Guy Smith-Ferrier for dragging him away from the Bristol Girl Geek Dinners (http://bristolgirlgeekdinners.com) crew so I could catch my train back to London.

  • Agile Testing Days 2012 – Day 1 – The birth of the #unicorn…

    - by Chris George
    Still riding the high from the tutorial day, I arrived at the conference venue eager to get cracking with the days talks. The opening Keynote was “Disciplined Agile Delivery: The Foundation for Scaling Agile” presented by Scott Ambler. The general ideas behind the methodology such as not re-inventing the wheel, and being goal driven, not prescriptive in how you work certainly struck chords with how we are trying to work in my team. Scott made some interesting observations about how scrum is quite prescriptive and is this really agile? I agreed with quite a few of his points on how what works for one team may not work for another. How a team works should be driven by context and reflection, not process and prescription. However was somewhat dubious about some of the statistics he rolled out towards the end. However, out of this keynote was born something that was to transcend this one presentation. During the talk, Scott mentioned on more than one occasion “In the real world”, and at one point made reference to people living in the land of unicorns and rainbows. The challenge was then laid down on twitter for all speakers to include a unicorn in their presentations… and for the most part this happened! It became an identity for this years conference, and I’m sure something that any attendee will always associate with Agile Testing Days 2012! Following this keynote, I attended “Going agile with Automated GUI Testing – Some personal insights” by Jan Zdunek from codecentric on the vendor track. My speciality is test automation, and in particular GUI testing, so this drew me to this talk more than the others. Thankfully, it was made clear from the very start that this was not peddling any particular product (even though it was on the vendor track), and Jan faithfully stuck to that. Most of the content was not new to me, but it was really comforting to hear someone else with very similar experiences to my own. In particular, things like how GUI testing is hard and is not a silver bullet; how record & replay is NOT a good thing to do (which drew a somewhat inflammatory tweet from an automation company when I tweeted that!). Something that I have started hearing around the place, and has certainly been murmuring at work is to push more of the automation coding onto the developers. After all they are the coding experts. I agree with this to a degree, but I personally enjoy coding and find it very rewarding doing so, therefore I’d be reluctant to give it up. I think there are some better alternatives such as pairing with a developer. Lastly, Jan mentioned, almost in passing, that we should consider virtualisation for gui testing for covering configuration combinations. On my project we’ve been running our win32/.NET GUI tests in cloud virtualisation for a couple of years now… I really should write about that! After lunch the second keynote of the day was by Lisa Crispin and Janet Gregory,”Myths about Agile Testing, De-Bunked”. It started off well… with the two ladies donning Medusa style head bands whilst they disbanding several myths about agile testing! I got the impression that it was perhaps not as slick as they would have liked, but then Janet was suffering with a very sore throat so kept losing her voice. Nevertheless, the presentation was captivating, and they debunked several myths such as : “Testing is dead”, “Testers must write code”, “Agile teams always deliver faster”. I didn’t take many notes for this because it was being recorded, but unfortunately the recordings have not been posted yet so I’ll write more about this when they are. The TestLab was held during a somewhat free for all time during most of the afternoon. It looked intriguing and proved to be one of the surprising experiences of the conference for me. Run by James Lyndsay and Bart Knaack, it consisted of a number of ‘stations’ that offered different testing problems. I opted for testing a mathematical drawing app call Geogebra, the task being to pair up and exploratory test it. After an allotted time, we discussed issues we’d found and decided if we wanted to continue ‘playing’ to which we all agreed! It was fun! The last track talk of the day was “Developers Exploratory Testing – Raising the bar” by Sigge Birgisson. One of the teams at Red Gate have tried Dev or Team exploratory testing a couple of times, and I was really interested to go to the presentation that prompted that. I was not disappointed! Sigge gave a first class presentation, and not only explained what DET was all about, but also how to go about implementing it. Little tips like calling it a ‘workshop’ rather than ‘testing’ I can really see working! Monday evening saw the presentation of the award for the Most Influential Agile Testing Professional Person go to a much deserved Lisa Crispin. The evening was great, with acrobatics, magic and music. My Takeaway Triple from Day 1:  Some of the cool stuff that was suggested in the GUI Testing talk, we are already doing. I should write about that! Testing is not dead! Perhaps testing will become more of a skill than a specific role, but it is certainly not dead. Team/Developer exploratory testing… seems like a no-brainer assuming you have a team who is willing.  Day 2 – Coming soon…

  • I&rsquo;m going to have to stop using MS Virtual PC 2007

    - by John Breakwell
    Originally posted on: http://geekswithblogs.net/Plumbersmate/archive/2013/10/23/irsquom-going-to-have-to-stop-using-ms-virtual-pc.aspxFor many years now I’ve been happily chucking around Windows XP virtual hard disks and loading them with Virtual PC. Sadly I’m going to have to turn to something modern as the virtual processor is no longer up to scratch, as I found when trying to install Windows 8.1 evaluation. In the past this would have been a Blue Screen but they’re handled differently in Windows 8, usually with a frowning emoticon. 0x0000005D means UNSUPPORTED_PROCESSOR and the solution would be to enable No-Execute Memory Protection in the BIOS. Virtual PC is ancient so the AMI BIOS has no such setting on any of the menus. Off now to find a virtualisation product I like.
