Issue when running Ubuntu in VirtualBox - virtualbox

I installed VirtualBox on a Windows 10 PC. I installed Ubuntu v. 16.04 in it. But when I shutdown the virtual machine and restart it, it asks me to install it again. The installation itself is not saved to my virtual machine.

It sounds like your virtual machine is booting from the installation media.
In virtual box go to your virtual machine's configuration and ensure that you remove the live USB / disk image from the available devices section. However, a more suitable place for this question is Ask Ubuntu.

How to install CentOS7 in PRIMERGY TX1310 M1 which already has VMware ESXi 6.5 server in it?

I have a FUJITSU PRIMERGY TX1310 M1 with VMware ESXi 6.5 server running.
How do I uninstall this and then install CentOS7 to this machine?
I am new to building servers and would be happy if somebody could help me out on this.
Warm regards,
sunnyday
You will need to start the physical system and point it to either a CD-ROM and/or ISO which contains CentOS7. Once booting from the CD-ROM or ISO, it will walk you through the installation process.

Copy + Paste funcionality doesn't work between host and virtual machine both VirtualBox and VMWare

Good morning,
I cannot copy&paste between host and virtual machine. It seems that both host and VM won't share Clipboard.
I tried many programs and different virtual machines and it doesn't work at all in both directions.
I can't copy anything.
Host is Windows 10. I tried:
VMWare Workstation 12, VMWare Workstation 15 - Fedora (Gnome, lxqt, lxed)
VirtualBox - Fedora (lxqt), Solaris, Windows 8.1
All options inside VirtualBox either VMWare were set properly.
On any of listed machines copy&paste doesn't work.

VMware Tool doesn't install

I have a virtual machine with Windows XP. And my host computer is on Windows 10. I'm using VMware version 14. I'm trying to setup a shared folder for my virtual machine and faced with an issue that Shared Folder doesn't appear on my VM. I've started investigate and found that VMware Tools are not installed on my VM. When I go Player -> Manage -> Install VMware Tools -> nothing happens. I don't see any pop-up windows with installation. It seems like virtual CD is inserted but nothing more. I can't see it in My Computer.
What did I miss?
Can you ping your XP VM from your Host Win 10 Machine?
If you couldn't ping your XP VM IP from your host machine, turn your firewall off on both machines and try to ping again.
Did you turn on your network discovery on your Windows 10 Machine and XP Machine?
If you can ping your VM from Host machine, turn on file and print sharing settings.

Are any changes made to the host Operating System upon installing any package in virtualbox?

My host OS is windows and I installed CentOS in virtualbox. Will the packages that I install in the virtual box, be accessible/modified in windows?
Are any changes made to the host Operating System upon installing any package in virtualbox?
No.
Will the packages that I install in the virtual box, be accessible/modified in windows?
You should also be able to read and write files in the guest file system's disk image from the host system. With the caveat that the guest probably needs to be "off" while you do that, otherwise there is a risk of either corrupting the guest file system or seeing an inconsistent guest file system state from the host.
Installing packages in the guest does not modify the host operating system ... if that is what you were asking.

Enable hyper-V on Windows 2012

I have a window7 (32 bit) machine. I installed Virtual Box and created a VM (Windows 2012 {64bit} with enabled VT-x/AMD-V,Nested Paging).
I want to enable Hyper-V on this VM any Idea?
I tried following links but not working for me:
Link1
Link2
but in my case I am using Virtual Box.
How can I enable Hyper-V feature?
Do you want to expose VT-x/AMD-V to the guest system in the VM so it can run Hyper-V inside VM? As far as I know, VirtualBox does not support it, but VMWare does, even in their free VMWare Player.
I have been running Windows Phone 8 emulator in VMWare Player without problems. Yes, it required manual editing of .vmx file, but is works reliably and without any problems at all.
If you decide to give VMWare Player a try, make sure you have VT-x/AMD-V available and enabled on your physical host computer. Then add the following setting to your VMWare machine:
hypervisor.cpuid.v0 = "FALSE"
mce.enable = "TRUE"
and you should be able to start Hyper-V inside your VM.
For more information, see these links:

and some useful topics on VirtualBox forums which explain why the feature is not available on VirtualBox:

I really miss this feature on VirtualBox because I find VMWare Player to be bloated and it slows the host system down much more than VirtualBox does.
