I am using Windows 10 and try to install Red Hat in virtualbox. After its installation it asked me to reboot. But after reboot I will come the install UI again. May I ask has anyone met similar problem?
I have ensured that I have disabled the Hyper-V function. And I installed Ubuntu propertly in VirtualBox two days ago.
Versions:
Virtual box: 6.0.8-130520
Red Hat ISO: rhel-8.0-x86_64-dvd
Unbelievable, I have to mannually remove the installingt ISO in virtualbox via:
Settings-> Storage and remove the installing ISO there.

After MacOS is upgraded to 10.15.X (Catalina), JDK cannot be opened. The message shows "JDK cannot be opened because the developer cannot be verified".
According to java.com:
Changes introduced with macOS 10.15 (Catalina) cause certain Java
applications to behave incorrectly. Therefore, we cannot certify any
JDK version on macOS 10.15 yet. However, as of now, you can install
and run non-notarized software on macOS 10.15 systems by modifying
your security preferences.

I want to install CentOS 7.5 on HP Proliant Microserver G8.
This server use a fake array controller (HPE Dynamic Smart Array B120i Controller) that need kernel specific driver to work.
I've found the driver package (rpm) on HP Suppurt site (b120i rhel7u4/rhel7u5)
I need to supply this driver to the OS Installer.
This it's possible passing linux modprobe.blacklist=ahci inst.dd but for some reason the installer only search for *.iso files.
Is there a way to provide an RPM kmod to the OS installer?
Any help will be appreciated.
You need another packages that are not updated since a lot of time ago: hpvsa-xxxxxx-dd.tgz. Last time I checked it was updated just to rhel7u3. You can find lots of howtos about using it with the CentOS installer.
Install CentOS 7.3 with hpvsa driver, then update to CentOS 7.5 and without rebooting install the kmod with rpm.
Nasty support from HP :/
I am having trouble trying to install OpenCV correctly and configure it with Netbeans.
One of my University units is using Visual Studio with OpenCV but I do not own a Windows PC so need to install OpenCV on my Mac OSX 10.12.3 and configure it to work with netbeans in a C++ project.
I have explored many avenues to do this but can't seem to come to a solution.
If someone could provide a step by step guide, that would be very helpful. Ideally I would like the most recent version of OpenCV.
Option 1
Install Oracle VirtualBox for free on your Mac and then install Windows in a virtual machine. It is a single file on your Mac so you can remove all that ugly Microsoft stuff as soon as you finish your class. You can run the virtual machine at the same time as macOS (it is not dual boot and doesn't mess with your boot sector) and copy and paste between the two, share files between the two and use networking from the virtual machine.
Option 2
Get a free Amazon EC2 Windows instance and run your OpenCV and NetBeans on there. You can connect from home using RDP from your Mac and also from school so your work is always accessible.
Option 3
Install homebrew on your Mac, then install OpenCV and NetBeans with
brew install opencv
brew install Caskroom/cask/netbeans
Then configure the two to work together as per this post.
I purchased a network card to give a separate network to my virtual machine. My host OS is Ubuntu 14.04 . Also i need to mount the USB to my virtual machine and not my host OS, so i downloaded extension pack version 5.0.2 for Vbox-5.0 . While installing virtual box extension pack, there were two VM's running and i got this popup.
Failed to install the Extension Pack /home/aniket/Downloads/Oracle_VM_VirtualBox_Extension_Pack-5.0.20-106931.vbox-extpack.
Failed to load the main module ('/usr/lib/virtualbox/ExtensionPacks/Oracle_VM_VirtualBox_Extension_Pack/linux.amd64/VBoxPuelMain.so'): VERR_FILE_NOT_FOUND - /usr/lib/virtualbox/ExtensionPacks/Oracle_VM_VirtualBox_Extension_Pack/linux.amd64/VBoxPuelMain.so: undefined symbol: RTLogRelGetDefaultInstanceEx.
Result Code: NS_ERROR_FAILURE (0x80004005)
Component: ExtPackManager
Interface: IExtPackManager {3295e6ce-b051-47b2-9514-2c588bfe7554}
Even after power off of VM's and restarting the host OS, I get this similar error code.
Sorry if you think the question is not formatted properly or any other issue with my question. This is my second post, please tell me if there are any things i need to correct in my question.
Thanks in Advance.
After lot of test and trial, the solution I found that the extension pack was not compatible and hence I had to download the compatible version of the virtualbox I am running on.
What happened was this, I was running virtualbox-5.0 and the version I was trying to install was 5.0.20 .
You can check your version by clicking on Help and then About Virtualbox and download the exact compatible extension pack, else it will through the same hex error code 0x80004005 which means file not found.
Run vboxmanage command with sudo, i.e.:
sudo vboxmanage extpack install Oracle_VM_VirtualBox_Extension_Pack-5.1.22-115126.vbox-extpack --replace

I uninstalled virtualbox,then reinstall it. After this the extension pack got installed successfully. My version is `5.1.12 r112440 (Qt5.6.2)
I encounter this problem again, but this time I disable my antivirus software(mcafee), that is ok. refer by https://www.virtualbox.org/ticket/7972
I am trying to write some openFrameworks (C++) code in a VM. My host is Windows 8 and I've tried both Arch Linux and Ubuntu guests. My host computer runs the graphics code just fine with an NVidia Optimus setup and 8GB of RAM.
I do my main development in Visual Studio, however I do prefer to create Android and test packages from Linux. For this reason I just want to fire up a VM and take care of business. The problem is that some of my graphics apps need OpenGL 3+
Has anybody else had the same problem and solved it?
Give up on VirtualBox. VB's OpenGL guest support craps out at 2.1, even then only after you install VB Guest Additions from the command line with switches and then add some Registry keys to actually enable the OpenGL guest drivers.
If you're willing to shell out money, VMware Fusion for Mac and VMware Workstation for Windows both support DirectX 10 and OpenGL 3.3.
A bit late to the party here, but hopefully helpful for someone encountering similar issues these days:
The mesa software renderer now supports OpenGL 4.5, so for me, the solution is to disable 3D acceleration in the settings of the VirtualBox machine!
The mesa software OpenGL support then takes over and provides its capabilities. It's for sure not that fast, but for my purpose (testing whether an OpenGL application starts and displays something under linux) it's sufficient!
Tested both on Fedora 34 and Ubuntu 20.04.
Try VirtualBox and prepend MESA_GL_VERSION_OVERRIDE=3.0 MESA_GLSL_VERSION_OVERRIDE=130 to your linux command line. Some of the opengl3 functions may work. Though not all of them will. I used that to bring up Civ5, the animation did not show up, nor did the on-screen fonts.
If you want to see the source code:
VirtualBox uses chromium 1.9 that is opengl 2.1. The info can be verified by the glxinfo command. Use the following commands to track the VirtualBox opengl lib file:
$ ldd /usr/bin/glxinfo
$ apt-file search /usr/lib/x86_64-linux-gnu/libGL.so.1.2
$ LIBGL_DEBUG=verbose glxinfo
Then follow links:
$ ls -l x86_64-linux-gnu/dri/
lrwxrwxrwx Apr 14 2014 vboxvideo_dri.so -> ../../VBoxOGL.so
$ apt-file search /usr/lib/VBoxOGL.so
virtualbox-dbg: /usr/lib/debug/usr/lib/VBoxOGL.so
virtualbox-guest-x11: /usr/lib/VBoxOGL.so
$ dpkg -l virtualbox*
ii virtualbox-guest-x11 4.1.18-dfsg-2+deb7 amd64
$ apt-file list virtualbox-guest-x11
...
The source code tarball was virtualbox-4.3.10-dfsg.orig.tar.gz from trusty repo. The version string can be grep'ed by $ grep -r CR_OPENGL_VERSION_STRING * and $ grep -r CR_VERSION_STRING * in the source code directory.
Update 6/1/2017: Someone told me the kvm works for civ5. A quick search turned up this thread titled "GPU Passthrough with KVM: Have Your Cake and Eat it Too". The thread is too long to read, though hope it could be useful to somebody.
