Network issues on OS X 10.10 Yosemite

[lclemente]

I'm having trouble with guest network connectivity with Virtualbox 4.3.12r93733 running on OS X 10.10 Yosemite build 14A238x. There seem to be two issues with a Ubuntu Trusty VM i created using vagrant:

• Network connections (e.g. ssh sessions) to the VM keep hanging for 1-2min. When typing in ssh sometimes the shell is unresponsive for a couple of minutes.
• Network connections from the VM to the internet fail often (~50% ping drop), also this problem happens: ​http://stackoverflow.com/questions/24060099/docker-failed-to-pull-images-from-registry

I've tried: Restarting host / guest, recreating the VM, playing around with network settings (although I don't know much about that).

Let me know if you need any more details, I'm happy to help anyway I can.

This is also causing problems with docker downloading images. Please upgrade the severity of this bug, it is show stopping for us.

try disabling Bluetooth on the Mac. There are issues with Bluetooth and WiFi both being on with 10.10. It has nothing to do with VirtualBox. I have been running Ubuntu 14.04 in VirtualBox since I installed 10.10.

Issue still occurs for me with bluetooth disabled

Replying to russianator:

Issue still occurs for me with bluetooth disabled

I suspect it's a problem with Vagrant. I don't use Vagrant so I can't check.

Same issue, Mac 10.10 Beta + Vagrant +Ubuntu guest losing network repeatedly. Bluetooth on/off has no effect.

This seems still unresolved under OS X 10.10 Beta 3

Having the exact same problems here with Vagrant / VirtualBox. Ubuntu 14.04. SSH is very unresponsive (about 1-2 minutes to login) and about the same for any input to be recognised. Also fails to connect to the Ubuntu package registry while provisioning (consistent with the network problems described here).

Is this still a problem?

Suggested workaround linked in comment:7 turns off DNS proxy DNS host resolver, which obviously shouldn't affect ping.

Since initial OS X 10.10 release had known WiFi issues, I wonder if this is what you see here with 10.10 beta.
