Apparently VirtualBox wasn't able to start vboxnet0/vboxnet1, which I noticed when I did: $ ping -I vboxnet1 puffin connect: Network is unreachable The problem could be found with $ip link (...) 5: vboxnet1: <BROADCAST,MULTICAST> mtu 1500 qdisc pfifo_fast state DOWN mode DEFAULT group default qlen 1000 link/ether 0a:00:27:00:00:01 brd ...

While I don't have the exact setup you are using, I was able to run WebGL under firefox with the host running Fedora 21, virtualbox version 4.3.32, and Fedora 22 as the guest. I also tried Centos 7 as the guest, with success. So it is possible to run WebGL in a guest using VirtualBox. I also tried Fedora 20 as the guest with success. You may want to visit ...

I'm posting an updated answer, as because I needed to perform a few additional steps to install. I'm using VirtualBox 5.0.14r105127. Each command will have to be prepended with "sudo". yum update yum install gcc yum install kernel-devel yum install bzip2 yum install kernel-devel-2.6.32-573.el6.i686 mkdir /media/cdrom mount /dev/scd0 /media/cdrom sh ...

Use the Debian jessie-backports virtualbox package. The version is 5.0.14-dfsg-1~bpo8+1. I'm using it with zero problems on my AMD64 Jessie installation. Make sure you get rid of all other related packages and local installations first, of course. To install, add: deb httpredir.debian.org/debian jessie-backports main contrib non-free to your ...

Install the full xorg, plus virtualbox support (you might have to reboot after that): pacman -S xorg virtualbox-guest-utils If you really want to use startx you need either to change your ~/.xinitrc to start blackbox or install ugly old twm instead.

Your problem seems to be that your rc-local.service is started before vboxadd-service.service, but it should run after it. Now, rc.local is a SysV thing (where it runs at the very end of the boot process), the compatibility provided by systemd is not perfect (as you can see in your screenshot). You'd probably better off with a custom home-test.mount unit ...

You need to put your file in: /etc/init.d/ And then you have to change it to an executable file by: chmod +x /etc/init.d/myscript if this does not run you have to create a symlink to: /etc/rc.d/ ln -s /etc/init.d/myscript /etc/rc.d/ Please note that on latest Debian, this will not work as your script have to be LSB compliant (provide, at least, the ...

This is an odd question, but a good one. The truth is that you need to define light weight. There are embedded Linux systems that run in as little as 8 Megs of ram (probably less, but this is the smallest I have done). Of course those don't have a GUI or firefox. From what I find the best your going to get in Firefox is about 100-150 megs of ram. Xorg, if ...

I found out how to solve this. It is just a stupid error. VirtualBox use the network utility ifconfig which is deprecated for many distributions. I had net-tools installed which will install ifconfig but it looks like not all sub commands are support with this. The solution is to install net-tools-deprecated. ...

The Asus N10 Nano has the Realtek 8192CU chipset. I advise to configure the loading of the required kernel modules using the following procedure. Create the file sudo vi /etc/modprobe.d/rtl8192cu.conf, with: options rtl8192cu rtw_power_mgnt=0 rtw_enusbss=1 rtw_ips_mode=1 Then do: sudo rmmod rtl8192cu sudo modprobe rtl8192cu If the modprobe does not ...

Yes, on a computer that support 64bit, you can run 64bit or 32bit OS VMS with out any problem but reverse is not true. That's mean, you cannot use 64bit OS on a computer that support only 32bit. And, if you are really looking for a light weight Ubuntu flavor distro, I would recommend Elementry OS Of course, there are lot of light weight distro but with ...

Virtual Machine is just an ENV for the VM's. You can install 32 bit or i686 OS on any 64 bit Host OS as a VM Virtual Machine is just an ENV for the VM's. Install the VM tray & Guest Addition tools for better performance.

Of course the answer is very opinion based, but I would go with Ubuntu (or any of its derivatives like Kubuntu) as it offers a huge community (e.g. at http://ubuntuforums.org/ or the askubuntu part of the stack network) that is really helpful. Also, many blog posts etc. deal with Ubuntu. As you are new to Linux, this is what you should look out for. On the ...

I think this is a matter of opinion. Also, take in account there is hundreds of posts in Internet informing about the differences between distributions. http://lifehacker.com/5889950/how-to-find-the-perfect-linux-distribution-for-you Anyway, I agree with the link, I am also a beginner and using Linux Mint.

There is an answer to this question right here: http://stackoverflow.com/a/56198 The easiest way to check your workstation is to download the VMware Processor Check for 64-Bit Compatibility tool from the VMware website. You can't run a 64-bit VM session on a 32-bit processor. However, you can run a 64-bit VM session if you have a 64-bit ...

Well, not exactly. VT-X is an extension for virtualisation, enabling the guest system direct access to certain resources. It is used by hypervisors ("VMWare" "Virtual Box" etc.). If you want to run a 64bit Guest system, you need to have a 64bit Host machine. But you can run a 32bit Guest system on any Host (32 or 64 bit).

I had to set permissions not only in the hadoop-data foler as I thought, but in the hadoop folder itself: sudo chown -R hadoopuser /home/hadoopuser/hadoop/ I got the idea from here.

Simple way to check the ssh service is up and running locally on the guest: ssh localhost alternatively: netstat -an | grep -w LISTEN | grep -w 22 If not installed, have a look to http://askubuntu.com/questions/51925/how-do-i-configure-a-new-ubuntu-installation-to-accept-ssh-connections

Check List: Are you able to Ping Slave-1 ? Slave-1 IPtables have allowed SSH port ? Stop IPTables and try once. service iptables stop Slave-1 is having SSH service running or not ? If yes try restarting once. service sshd start service sshd stop service sshd restart Make sure you didnt changed SSH default port. Hope it will help.

It looks like you are using bridged networking and your host and guest already have different IP addresses, 192.168.1.2 for the host (what you call master node) and 192.168.1.5 for the guest (slave node). Don't be confused by addresses in the 127.x.x.x network. These are loopback addresses and they never leave the TCP/IP stack, i.e. two different machines ...

This error generally means you don't have the VB Extension Pack. USB 2.0 support is provided by the VB Extension Pack. So you either: a) install the VirtualBox Extension Pack (https://www.virtualbox.org/wiki/Downloads) b) reconfigure your virtual machine to not require USB 2.0 (in the VirtualBox Manager) click on your machine name -> Settings -> USB -> ...

I hit the same issue today after upgrading to 5.0.14 (I am on Ubuntu 15.10, using the official Virtualbox apt repo) I fixed it with: sudo /usr/lib/virtualbox/vboxdrv.sh setup

This worked for me - sudo apt-get purge virtualbox* Source: https://forums.virtualbox.org/viewtopic.php?f=7&t=65539 And this explains the problem - Note that some Linux distributions already come with all or part of the VirtualBox Guest Additions. You may choose to keep the distribution's version of the Guest Additions but these are often not ...

You can try new installation media (a new OS). Despite Oracle owning it, I have found that even relatively new versions of Oracle Linux are not always compatible with relatively new versions of Oracle Virtualbox.

Fedora 14 is years (4 years!) after EOL (end of life). Current version is 23. The repositories and packages for outdated releases are long gone. Please try to install some up-to-date version.

On CentOS 7, firewalld has replaced iptables as the default firewall. I had to use systemctl stop firewalld to pause the firewall to test the connection from host to CentOS VM. See more here: http://stackoverflow.com/questions/24756240/how-can-i-use-iptables-on-centos-7
