Can Virtualbox Run Live Guest Servers?

hi guys,

i have virtualbox running on centos 7
i want to install another centos7 vm
i googled and found a few sites that show setup
but none show your initial setup in virtualbox
when i want to create a new vm i am offered:
linux 2.2
linux 2.4 (32 bit)
etc etc

all look 32bit...i thought centos7 was 64bit...or is it just emulated?
the only logical choice i can see is either:
red hat (32 bit)
or linux 2.6 / 3.x (32 bit)

i know its only a vm and i can experiment without breaking things (only the vm install) but i have a bit of a time restraint...

I have VirtualBox up and running on my headless Centos 6 machine, am using http://sourceforge.net/projects/phpvirtualbox/ as a GUI, and created a virtual machine and installed Windows 7 on it.

I can access it using the VirtualBox console (via phpvirtualbox interface), however, only can see part of the screen and the mouse doesn't work properly. I can also access it using Windows Remote Desktop Connection using IP 192.168.1.200:9000 (why port 9000?), but again the mouse doesn't work.

I have the following ext packs installed on the server.

Do I need additional extensions to better interact with the guest? How are they installed? Thank you

Hi All

I'm trying to bring virtual guest from headless mode to gui mode in VirtualBox. But I don't know how to do it. I really appreciate if someone help me on this.

I usually run linux virtual machines in headless mode and connect to it through ssh. I have setup tigervnc-server on linux virtual machine, so that i can connect through vncviewer whenever i want to work on gui.

But recently, one of my friend said, I can also start virtual machine in headless mode in VirtualBox window by holding <SHIFT> key and press Start. Sure it did, it started in headless mode. But, now I don't know how to bring back window again.

Thanks you.

I am running Antergos Linux 64 bit on virtual box. when I try to do full system upgrade I get a error:

resolving dependencies...
looking for conflicting packages...
error: failed to prepare transaction (could not satisfy dependencies)
:: virtualbox-guest-modules: requires linux<4.0


I am using Ubuntu as my host OS and it's kernel version is 3.13.0-49-generic and in Antergos is using 3.19.3-3-ARCH. I guess both are less than linux 4.0

I don't know how to solve this.

I have Windows 8.1 Update as my HOST operating system.
I have installed vmware workstation and installed on it the latest
version of CentOS (7.0) as Guest OS.

I have 8 GIG of RAM and have allocated to VmWare around 5GIG~.
HDD size is 30 GIG.
I also have de-fragmented the HDD.

From the beginning of the installation of the CentOS it was SLOW. It is NOT a sudden change or decline in performance.

Formerly, I had installd CentOS 6.4 which worked OK and had not speed problem while I just had allocated 1 GIG of RAM. Where do you think lies the problem?

Hi guys

I have installed Linux in a virtualbox on a windows 8 laptop. I found the screen size in the vrtualbox running ubuntu to be too small so I looked around for a solution.

I came across this

'Use Xdiagnose From the Dash, search for and launch Xdiagnose, then enable all the options under the Debug section. Click the Apply button, then close the window and restart the system. You’ll have to restart. Logging out, then in won’t do.'

After doing so my screen went from bad to worse and now I can only see a pixelated view of my screen.

Does anyone know how to work around this problem and get a bigger screen in virtualbox ?

It would be great if someone could share and provide some useful pointers/ advice on the feasibility of running .Net C# code on Linux Headless VPS Servers.

I had Kali and Linux Mint installed and erased Mint to install Centos7. Grub was totally deleted and I could only boot into grub recovery. Many hours of cussing later I got Kali back, I can see Centos filesystem mounted on my desktop and in disk utility. I never finished setting Centos up as I was rushed out the door which probably caused the problem in the first place, for some reason it's raid and although it's 2 harddrives they are not set up for raid and 1 is Kali and 1 is Centos. The Centos boot folder is still empty after running grub-install on it twice and it does not show in grub. How do I get Centos as an option?
