After Ubuntu is upgraded, all data in VirtualBox cannot be used and is lost.

Upgrade is prompted today in Ubuntu10.04. After a rough look, in addition to browsers, there are also system kernels. After the system is upgraded, a problem occurs when the Virtualbox virtual machine is enabled.

We are prompted to upgrade Ubuntu 10.04 today. After a rough look, in addition to browsers, there are also system kernels. After the system is upgraded, a problem occurs when the Virtualbox virtual machine is enabled.

Tip: Failed to open/create the internal network 'hostinterfacenetworking-wlan0' (VERR_SUPDRV_COMPONENT_NOT_FOUND ).........

As a result, it was true that the image was still recovered. At last, I had to delete the image and reinstall it. After re-installing XP, I found that the above fault still exists. In the end, I had to GOOGLE, I found that the problem that can be solved with only one of the following commands was not completed in a day.

Solution:

$ Sudo/etc/init. d/vboxdrv setup

Sometimes, the system may have compatibility issues, such as virtual machine networks that can only be NAT but cannot be bridge. The solution is the same as above.
