Bug in virtualBox

[futex]

Hello all,

I'am on linux mint 18.1 up to date and i use the version 5.0.40_Ubuntu r115130.

My problem is i have a VM running another Linux with have two networks interfaces, the first one is binded on his internal virtual network (innet) and the second is NATed.
When i finished to work i freeze the VM, and when i start i unfreeze it, but the VM is unable to retreive IP on some interfaces, sometime the somertine the second. I have tried manualy to do a dhcp eth0/eth1 without success (the route table seem ok), And a reboot doesn't correct anything

Anyone have this behavior and/or have an idea to solveit?

Thank you

And if i reboot the problem disapear (sometime), but if i freeze the VM after the problem come back, and network manager on the VM is unable to retreive DHCP. I have check the route table, they are the same before (when all is ok) and after the freeze.
That's weird.

it's generally suggested that you use the V5.1.xx of VirtualBox:
https://www.virtualbox.org/wiki/Linux_Downloads
rather than the version, that you are currently using.

you will need to Un-install the version 5.0.40_Ubuntu r115130
- before you can install the later version, or you will get some errors, otherwise.
