[BlueOnyx:12303] Re: Server lose network connection

[Lew Berry]

Tried changing the adapters too. BX installer bails on the standard adapter. Rolled back to a previous kernel. No joy! At this point I'm guessing some windows update has broken it. Going to try a V2P conversion tomorrow.

My sympathies Lew.  I'm also fighting a 'BlueOnyx on Hyper-V' problem.  In my case, the LVM container won't mount - so the system can't get into the partitions to boot.  I'm still attempting to recover that LVM container. 

One of the things I've notices while having to manage multiple BX servers on Hyper-V - it occasionally looses the network configurations/connectivity.  Most of the time it happens, we're able to modify the Hpyer-V settings to get the networking back up.  Change it from "Public" to "Internal LAN", and then back.  Sometimes, we didn't even have to shutdown the VM.  Making the changes fixed it right away.  Other times, we'd have to shutdown/modify/reboot to fix it.  And in one case - we never got it fixed and I rebuilt that BX server..... 

OH YEA!  And make sure your Hyper-V VM is using a "Legacy Network Adapter", not the standard "Network Adapter".  If you're using the standard "Network Adapter" - you'll have all kinds of network problems (including loss of network connectivity like you're having).
