Networking no longer working after Parallels 10 and OS update

Hi -

I've been running a Ubuntu 12.04 vm for several months with no problem. This morning I installed the Parallels 10 update and the latest Apple security patches. Now I can no longer see any external network in my guest OSes. When the linux OS comes up it does not see *any* interfaces besides lo.

My Parallels configuration:
- One interface "Host Only"
- One interface "Default Adapter"

On the linux side:
- Host only is set with static IP
- Default adapter is set to DHCP

What I've done so far:
- Couple of reinstalls of Parallels tools
- Use only one adapter against each type (host only, shared, bridged)
- Power cycled both guests and host machine

Again, this was a working configuration until OS and Parallels updates.

TIA!

 

Update on this. I left the vm untouched for about an hour and the interface appeared and configured via dhcp correctly...
