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 :-) Sorry for the noise James Pearson ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

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. ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

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.

Ah, I think I misunderstood. So far my vbox/Centos-7 experiments have been using Centos-6 (or Win-7) as the host and C-7 as the guest. -- Fred Smith -- fre...@fcshome.stoneham.ma.us - "And he will be called Wonderful Counselor, Mighty God, Everlasting Father, Prince of Peace.

Can you tell me where exactly they have got the appropriate RPMs to CentOS 7 from? The closest I can find in under https://www.virtualbox.org/wiki/Linux_Downloads but the RPMs for Enterprise Linux are only available for the 6 Series. When trying to install such a RPM I get an error message which consequently complains that Python is installed in the wrong version. This is probably an easy problem to solve, but I'd like to avoid to contaminate my installation with third party packets when it is "official" is a way.

There's an RC of 4.3.14 available, and so far the video driver support for an EL7 guest seems to work OK for me.

I always just download it from virtualbox.org, also making sure to get the extensions package for the same veresion, also from virtualbox.org. they offer binaries for all the "big" linux versions, inncluding .RPM for RHEL/Oracle Linux, and you would use that one for Centos. What they don't have yet, is the "guest additions" for EL7.
