I'm running ubuntu 14.04.4 as a VM on Hyper-V (Server 2012 R2). The VM is configured to only have 1 VCPU and 2GB fixed ram.
Shutting down, or restarting takes around 15 minutes (sometimes a lot longer). The terminal disconnects immediately, and I can't reconnect but other than that nothing appears to happen. Connecting to the VM (I think it's called tty1, but I'm very new to linux!) I can see this:
In Hyper-V the state goes to "Stopping-Critical" and the status is "In Service". Eventually the machine wills top.
I've had a look around the issue but I'm struggling to find any obvious issue (I also can't tell if Hyper-V is causing the issue or not).
I think I might need to do something with grub to show me more info, but I'm a little out of my depth here! Any advice would be really useful!
After rebooting another ubuntu machine running on the hyper-v server I can see it's having the same issues. I'm going to move the machine to another hyper-v server and see if that is the issue, but at the minute I suspect it is.
