Installing Ubuntu guest crashes Hyper-V host
- by Grant
I have a weird problem that I don't even know where to begin diagnosing. Trying to install Ubuntu to a VM locks up the host system!
My setup is:
Dell R715 server, dual 16 core AMD opteron processors, 96GB RAM
Dell MD3600f SAN
Server 2008 R2 Datacenter
System Center VMM 2012
There are 5 windows virtual machines running that have had no problems. This is the first linux VM I've tried to create. I setup a VM through virtual machine manager, set the CD drive to a Ubuntu 12.04 server x64 iso, and started it up.
It boots up the normal ubuntu install menu, but the second I hit enter on "Install Ubuntu Server", I get disconnected.
The HOST machine stops responding to pings. So do all virtual machines on it. It locks up entirely - keyboard on the host won't work, mouse won't move, numlock light won't change.
There's no blue screen - the host is sitting at the login screen completely unresponsive. I can't find any relevant logs in event viewer after rebooting.
What could cause the host machine to freeze like that?
It's not a one time occurrence - it happens every time at the exact same point. Thank god this server isn't in production yet!
