I have a "demo" virtual machine with Ubuntu OS for our sales people with gets updated periodically and then re-deployed (copied) to the client machines (Win 7 x64).
I am used to errors at first start about missing/wrong network adapters, which is "ok" - the clients' interfaces are different to mine (I update the VM).
This time I get errors: Failed to open/create the internal network ...
The network adpater is online/active without errors.
Of course I tried rebooting and double checked the VM configuration and linked network adapters from the host machine.
In the first client the network config was fine, but when I start up the VM and I get the message, all adapters in virtual box are labeled "adapter 0" and empty! (I can go to the VM setting from the error screen).
After I cancel the startup and check on the VM settings again, all infertaces are fine again.
On one client notebook I suddenly was able to poweron the VM. I saw there wasn't enough free mem on the host client so I reduced it for the VM and it booted. Also I had the notebook detached from its dockingstation, but this shouldn't make any difference in windows or VM drivers.
I tried that on the second client notebook without any success.
I did the exact same things (checked available memory, detached from dockingstation,reboot etc) but no chance :(
I also tried disabling all VM interfaces - then the VM startsup fine but this doesn't solve the issue; I need to address the vm-interal webserver by host-only IP.
Booting up with disabled network bridge but enabled host-only adapter also does not work and ends up in the same error message.
Does anyone have a clue on this?
Attached there is also a screenshot of the exact error message.
Starting a new version of the VM has never been such a pain. The old one was removed before.
I already found some hits on google but without success so far.
I.e. i removed the key under HKEY_LOCAL_MACHINE\SYSTEM\
ork "MaxNumFilters" and rebooted...
We use Oracle Vbox 5.0.4 on all machines - no differences in version.
Has anyone encountered this before?
