virtualbox disables host network on win 8 consumer preview

It is NOT about installing win 8 on virtualbox as a guest OS.

I installed VB on win8 host. Win8 lost its network connection right after reboot/sleep/hibernate. It seems that win8 recognizes only VB Host-Only adapter. The problem was gone when I uninstall VB.

I googled it. It could be solved on win7/vista by changing *NdisDeviceType to 1 in reg. But I got no luck on win8 cp. I found a work around, unchecking virtualbox bridged networking driver in adapter properties. It works so far after waking from sleep. As win8 is still cp, I hope this will be fix in new version of VB and win8.
