I have Windows 10 and first installed VirtualBox version 5.0.10 r104061 a couple weeks ago and installed PeopleSoft HCM, HCMDB-SES-854-14. It has been running flawlessly for about 2 weeks.

I received automatic Windows updates overnight, and since then PeopleSoft will no longer start on the VirtualBox. I get the errors below:

Could not start the machine HCMDB-SES-854-14_1 because the following physical network interfaces were not found:
VirtualBox Host-Only Ethernet Adapter (adapter 1)
You can either change the machine's network settings or stop the machine.

Failed to open a session for the virtual machine HCMDB-SES-854-14_1.
Nonexistent host networking interface, name 'VirtualBox Host-Only Ethernet Adapter' (VERR_INTERNAL_ERROR).
Result Code: E_FAIL (0x80004005)
Component: ConsoleWrap
Interface: IConsole {872da645-4a9b-1727-bee2-5585105b9eed}

I have tried changing the settings and was able to get what appeared to be a successful start up, but after that I cannot log in to the PeopleSoft HCM application, nor to Application Designer and cannot connect to the database using SQL Developer.

It appears that the settings for the Network tab for Adapter 1 are no longer valid. When I open that tab, there is a message at the bottom of the page "Invalid settings detected". The settings are:

Enable Network Adapter: checked
Attached to: Host-only Adapter
Name: Not selected (and no choices are available)
Advanced
Adapter Type: PCnet-FAST III (Am79C973)
Promiscuous Mode: Deny
MAC Address: xxxxxxxxxxxx
Cable Connected: checked

Uninstall 5.0.10 (don't worry, your VMs are going to be fine) and update to 5.0.12. See if that fixes it...

Thanks for the suggestion to reinstall/upgrade the Virtualbox and that it would not affect my VMs. I had been considering that, but was concerned about losing my data.

In the meantime, I have gotten my PeopleSoft application to work again. These were the steps that fixed it:

1. For some unknown reason, my Virtualbox Network settings had become invalid. They were set to "Host-only Adapter", with the Name "Not selected", which causes an invalid condition. I don't recall if these were the original settings or if they somehow got changed by a software update. I changed this to "Bridged Adapter" with the Name "Intel(R) Dual Band Wireless-AC 3160", and this caused the invalid condition to go away.

2. I restarted the VM. This time, every process started, but I was still unable to access the web application, Application Designer or Oracle database (using Oracle SQL Developer).

3. On the VM, after all processes started, I logged into Unix as root, ran the ifconfig command to get the inet address and discovered that it had changed since the initial installation. I took the new inet address, updated my tnsnames for the database and updated the U R L used to access the web application. After this, everything was successful and back to normal.

The inet address had never changed since my initial installation and restarting the VM several times, so I assume that the change was related to the Network settings change.

My issue is resolved now, but if anyone can explain what might have caused this issue to happen in the first place,that would be good to know.
