Ticket #4165 (closed defect: duplicate)
Using NAT, ssh logins from Guest to Host disconnect under high CPU Usage
|Reported by:||pablo||Owned by:|
|Version:||VirtualBox 2.2.4||Keywords:||nat disconnects guest to host|
My environment is the following:
- Host O/S: openSUSE 11.0
- Guest O/S: Win XP/SP3
On the Guest O/S I run Cisco VPN software. I also run ssh (cygwin) to setup port-forwarding between my Host O/S and the Guest O/S
With the above setup, my browser on my Host O/S can access the internal web servers via the VPN. In short, the Guest O/S acts like a bridge.
The above works very well when I use either NAT or Bridging for the Guest O/S
The problem is, and I'm not 100% sure this is the cause, when my Host O/S is under heavy CPU load and I'm using NAT, the ssh connection between my Guest O/S and Host O/S drops. As I'm also sshd to the remote servers, these connections are dropped.
The above only happens when I'm running a browser which is displaying Oracle Grid data (somewhat CPU intensive) and I'm using NAT
If I use Bridging on the Guest O/S, the problem never occurs.
As I travel at times, I can't always use Bridging on the Guest O/S
Please let me know how additional forensics can be collected so we can resolve the issue.
