Hi all,

configuration:
laptop macbook pro retina (late 2013)
OS Mavericks 10.9.1
virtualbox VirtualBox 4.3.6
Vm guests Oracle Enterprise Linux 6.5 or Solaris 11.1 doesn't matter, my problem is the same.
Each vmguests has configured a Host Only Adapter.


I have noticed that after a random time, if I open a ssh connection towards my VMguests, network become slow and than hang for short or long time.

Someone has the same issue? Workaround ??

Thanks

Seen it. IIRC it coincides with network changes on the host OS, e.g., when a VPN connection times out and disconnects.

Hi,
this issue is present also if I restart my laptop without network device actives (no wifi, no ethernet adapter insert).

No vpn configuration present.

Have you tweaked your host-only network? Because the address that you ping is not the "default" for a host-only network, it seems more like a Bridged one. Can you re-check please? Even better, can you post a log of a machine (from boot up to normal shutdown) that exhibits this problem?

yes I have changed it. I don't see any problem here.

I have attached the logs of 2 vmguest and also a simple ping test between host and vmguests

New update,...

if the vmguests are started as:

$ VBosHeadless -s nome

Network is running perfectly without problems.

Reproduce the problem then provide the VM log file, the guest settings, and the output of the following commands on the host : Then on the host & guest - you might need to find the equivalent command on the system, or use sudo :
