Version 6.1 is running without problem for me.  I download the rpm from
virtualbox.org.  I usually remove the old one before installing. Don't know
if any of that helps.

Yes.

It "just works" for me.

How did you install it?  I installed it with dnf using the VirtualBox rpm and 
didn't get any error messages.

I just checked and I don't have any "elflibs" rpms on this computer, either.  I 
do have elfutils-libelf, though, which may be something similar or may be 
entirely different.

Again, though, VirtualBox works fine here.   
VirtualBox-6.1-6.1.12_139181_el8-1.x86_64 according to the output from the rpm 
-q command.

So all of this makes me wonder if the problem is the way that you installed it 
or what you did to satisfy the mystery dependency(?) on elflibs, whatever that 
actually may be.

[CentOS] VirtualBox extensions and the new kernel

[Klaus Kolle]

I've been running Centos for different purposes in a VirtualBox
environment for quite long now. But the newest kernels miss something so
I can get the VirtualBox Extensions linked in.

I can see in the virtualbox log file that I shall run maken oldconfig
and make, but I get these errors:

# make oldconfig && make prepare
scripts/kconfig/conf --oldconfig Kconfig
#
# configuration written to .config
#
scripts/kconfig/conf --silentoldconfig Kconfig
make[1]: *** No rule to make target `arch/x86/syscalls/syscall_32.tbl',
needed by `arch/x86/syscalls/../include/generated/uapi/asm/unistd_32.h'.
 Stop.
make: *** [archheaders] Error 2

Probably it is something that I misses, but what, I cannot figure out.

I see the problem both in Centos 7.7 and 8

I've manged to 'solve' the problem - which wasn't anything to do with 
CentOS 7 ... the host running CentOS 7 was patched into a switch with 
MAC access control enabled - as were the two other CentOS 7 boxes I 
tried - whereas the CentOS 6 host(s) I used had no MAC access control 
enabled

Just wish it hadn't taken me nearly a day to work that out :-)

What kind of hardware? There can be issues with trying to bridge across a
WiFi connection and you may need to use NAT. On wired on a server I've had
issues where the network had multiple VLANs allowed directly to the
ethernet adapter and I had to configure where the VLAN was being tagged for
the VMs. A bit more fleshed out description of your hardware and network
set up would help out.

I hate to be the first to say "works for me", but it does! :)

I have (or have had) many VMs in Virtualbox, both Windoze and various
flavors of Linux, as well as one or two other things. I always set
them up as bridged and they "just" work.

Can't think of what might cause it, but you might want to look at
/var/log/messages, etc., on both the guest and the host. Make sure
the vbox kernel module(s) is(are) installed. I don't think the vbox
tools for the client would have anything to do with this, but it won't
hurt to check that they are properly installed.

Good luck!

[CentOS] VirtualBox on CentOS 7 with bridged network not working

[James Pearson]

I've installed VirtualBox v5.2 on a CentOS 7.4 machine, but VMs set up 
with bridged networking can not 'see' past the VirtualBox host machine

i.e. the VM can ping the host and vice versa, but the VM can not ping 
anything else and other machines on the same subnet can't ping the VM

There are no firewall rules configured on the 7.4 host and selinux is 
disabled

I have a similar set up on a CentOS 6.9 host, where everything works as 
expected

Googling doesn't show up any similar issues, so I guess I'm missing 
something on the host machine

Does anyone have any idea what could be the issue?

How do you make a Virtualbox image of C7 so that when you EXPORT that image
and someone imports it that the values in /etc/fstab will be OK.

Example:
UUID=13813d49-15b7-48ed-ab0d-da52aa3a9078 /   xfs

/dev/mapper/centos-swap swapswapdefaults0 0

Then the exported, imported image boots its still referencing
the first UUID there and it cannot find it so it does not boot.

How can I change this so my image runs, and then when I export it and
someone imports it
that their image runs. ???

When trying to install such a RPM I get an error message which

This is probably an easy problem to solve, but I'd like to avoid to

As Barry notes, you need to resize the file system.  Since you already
resized the LV, you need to use resize2fs.

You could have resized both the LV and file system with lvextend in the

 As Barry notes, you need to resize the file system.  Since you already
 resized the LV, you need to use resize2fs.

 You could have resized both the LV and file system with lvextend in the
 beginning (using one command) by passing -r or --resizefs parameter to
 lvextend.


That's good to know.  I'll put it in my notes.

[CentOS] virtualbox, lvextend, etc.

[Wes James]

I'm using virtualbox with one of the tests I have for centos 6.4.  I
realized after creating the disk, the default was too small.  I added more
disk space with:

VBoxManage modifyhd /Users/user/VirtualBox\ VMs/centos\ 6.x/centos\ 6.x.vdi
 --resize 25000

I then used this site to help me resize the lvm:

http://community.spiceworks.com/how_to/show/2768-extending-lvm-partition-with-free-space-from-the-same-hdd-or-with-a-new-partition-from-a-new-hdd-on-centos

but when I do:

df -h

I still see only the original 8gig disk (8gig total - 4gig data/4gig swap)).

When I look at pvscan in lvm, it says 23.92GiB is the size of the volume.

Why doesn't df see it correctly?

Thanks,

Re: [CentOS] VirtualBox on CentOS 6.0?

[Roy Trubshaw]

A few things:

- It didn't/doesn't play well with other virtual machine libraries.
- Don't forget to install the vbox extensions if you want/need to use USB 2.0
- Don't forget to install DKMS before pretty much anything else.

- It _is_ worth the hassle of adding the vbox guest additions to support 
seamless mouse and keyboard integration
- ... not to mention resizing the machine window
- Here's a relatively complete description on turning VirtualBox into a service 
under Redhat/Centos/Fedora 
(http://www.kernelhardware.org/virtualbox-auto-start-vm-centos-fedora-redhat/). 
Though I'd replace vboxmanage with vboxheadless. [Can't be bothered to remember 
if either of the two apps are camelcase or not - check.]
- Dismount the guestadditions ISO / O/S installation ISO / any other 
non-essential ISO _*before*_ you take a snapshot. 8-)
- If you want the guest system to be a server you need bridged networking (it 
works pretty well 'out of the box' actually).
- RTFM (really)

It was the first VM I used (mainly because it works on hardware the doesn't 
support hardware virtualisation) and the only real problems I have had have 
been 64bit guests on 64bit hosts (both windows and unices).

YMMV

Subject: [CentOS] VirtualBox on CentOS 6.0?

I have an older quad-core AMD processor that supports hardware
virtualization on a motherboard that does not support it in the bios.

Eventually I'll swap the mobo out on this box for one that will support
hardware virtualization and use qemu-kvm. I prefer kvm because of
SELinux and sVirt that protects the host from VM breakout should a VM
become hostile.

In the meantime, I want to start work on a web project and want to use
this idle machine and CentOS 6.0 in a VM. What I prototype and learn
will eventually be moved to the production machine using kvm and sVirt.

So...I downloaded and installed Virtualbox 4.x but haven't yet had the
time to check it out.

Any tips/tricks concerning it?

I had problems with VBox 4 in my CentOS6, so I had to install

VMware Server meant a lot of problems with new kernels and the patch

I use VBox 4.x (there is even repository for it) without problems. There 
was some initial problems with USB, but it was solved 3-4 months ago.

Notice that you can not upgrade 4.0.x to 4.1.x. You have to uninstall 
previous minor version to install newer minor version, but all settings 
remain the same.

On my windows Guest (banking app and sometimes for support) sometimes, 
after initial start, I have to restart guest to recognize card reader, 
but once it is up it is rock solid.

Use VBox share folders for nice network file sharing.

If you want to install Virtualbox in CentOS, it is easy. Go to this download 
link http://download.virtualbox.org/virtualbox/4.1.4/VirtualBox-4.1-4.1.4_74291_rhel6-1.i686.rpm .
 and download the RPM File, after simply install it.

I am not such a fan of Virtualbox neither but You can try installing VMware 
Player or buy VMware workstation, Both of them work perfectly on CentOS.

Using VB 4.1.x under CentOS 6 to run CentOS 5  6 and WindowsXP guest VMs
without issue.  Be sure to read the comments on the above link, the script
needs some minor adjustments.

Being able to copy guest VMs between Linux and Windows Hosts supports a
robust development and fall back environment.

While I have noticed a few minor issues with VB, overall it has been
stable.  The issues I've noticed are occasional screen paint issues using
seamless mode and there is no way to delete a snapshot without applying the
changes from the snapshot.

4.0.x was okay for me (Windows server guests) but 4.1.4 was a complete

This doesn't appear to be universally true.  We've run 4.1.4 with Windows 7
64bit on top of CentOS 6 and not seen any noticeable performance problems.

  I recently doownloaded and installed the latest RHEL5 rpm from the VirtualBox

  This seems to be a very common problem. Many references to it turn up in a
  web search, but I have not found a solution that works on CentOS 5. I got no
  response on the vbox-users mailing list either. Can anyone here help?
 
  Among the things I tried were various /sys and /proc/bus/usb related fstab
  and rc.sysinit changes. Drew a total blank on this one ...

I have had the same problem. The only thing that I've found to work is this:

Get your vboxusers group ID
# cat /etc/group | vboxusers

Remount the USBFS with your vboxusers GID
# mount -t usbfs -o remount,devgid=GID,devmode=664 /proc/bus/usb 
/proc/bus/usb

Change the permissions on /dev/vboxdrv
# chmod g+rw /dev/vboxdrv

Restart the vboxdrv service
# service vboxdrv restart

Now when you boot your VM up the USB devices aren't greyed out any 
longer. I suppose you could script this if you wanted, add the usbfs 
mount to /etc/fstab and have the chmod go in a startup script or something.

 This is the bit that won't work. The mount options seem to have no effect:

# ll /proc/bus

 Change the permissions on /dev/vboxdrv
 # chmod g+rw /dev/vboxdrv
 
 This one is new to me ...

 Restart the vboxdrv service
 # service vboxdrv restart
 
 ... and this one resets the permissions on /dev/vboxdrv to 600.

 Been there, tried that.

 VirtualBox actually complains if you mess with /sys/bus/usb/drivers:

 You seem to have the USBFS filesystem mounted at /sys/bus/usb/drivers.
  We strongly recommend that you change this, as it is a severe
  mis-configuration of your system which could cause USB devices to fail
  in unexpected ways.

Ridiculous, I know...a computer should know what you're thinking and how 
to spell it. :)

I tried everything in that post as well, and nothing worked for me. 
Finally I found the process I laid out and it worked.

The link to it is here which is an old ticket:

Not to doubt you, but you made sure to put your group id in 
devgid=some_number?

  ... and this one resets the permissions on /dev/vboxdrv to 600.

Hmmm, the permissions stay for me.

I too struggled to get USB to work, it seems to be pretty lacking with 
Linux support in VirtualBox, which is a big downfall. Although, I had a 
lot of issues with permissions with VMware Server as well when I ran it. 
I guess pick your poison.

This process works for me though, so I'm not sure what else to suggest 
to help you out.

You are building against the regular kernel-devel and not the 
kernel-PAE-devel.


you need to install kernel-PAE-devel and the /usr/src/kernels/version 
needs to contain PAE as well.

Ah ha!  I hadn't spotted the other devel kernels because I'd done a
  yum list 'kernel-devel*'

Thanks!
