Ubuntu Server on Hyper V Keeps Locking up

[fiza]

I have an Ubuntu Server on which I run the Concerto application for Digital Signage. When I had Ubuntu on a physical machine it ran fine. I have now built it as a VM on a beefy Windows 2008 R2 machine HYPER-V install but the Ubuntu server keeps locking up. Users cannot login to the Concerto web front end and I cannot ping the server. When I go into Hyper V and pause the server and then click Resume it kicks into life. I have given the ubuntu machine 1 Virtual Processor and 4GB RAM.

 

Any ideas why it keeps locking up?

 

Has anyone successfully run Ubuntu Server under Hyper-V?

Is the network adapter in Hyper-V a Synthetic or Legacy adapter?

Not a legacy Adaptor

[irsprint84]

has to be legacy

has to be legacy

 

Ubuntu includes the HyperV drivers. Once you enable them you can run synthetic network drivers.

 

Altough not officicly supported by Microsoft, it works great.

 

nano /etc/initramfs-tools/modules

& add below lines

hv_vmbus
hv_storvsc
hv_blkvsc
hv_netvsc

then run

update-initramfs –u

and reboot
