June 7, 201610 yr I have a general question on sleeping/waking etc. What happens to a VM when unRAID is set to sleep if the HDD's are spun down? Are they simple suspended also and wake back up when unRAID does? Is it possible to wake unRAID from USB connected to a VM? Here's my possible scenario. I have an i7 6700, 32GB RAM, 960GB SSD and a H170 motherboard that I was going to build a Windows 7 Pro workstation with. On this machine I'd use Stablebit Drivepool to pool my drives. Then obviously this machine could sleep when not needed but WOL when Kodi needed to access some content from the pool. Or I could run unRAID on the machine as a base OS and that would handle the storage pooling and sharing of data. Put a VM on top for my workstation and connect the monitor, keyboard and mouse etc. Probably won't be as fast with the VM but fast enough. But if I allow unRAID to sleep, how can I wake it to use the workstation? Also is it possible to stop unRAID sleeping if a VM is in use?
June 7, 201610 yr Community Expert Sleep is not officially supported on unRAID (it is a server OS after all) although many have had success in setting it up. As a result you will not get support from Limetech in this area, but only from forum members. From what I have seen it can be a bit hit-and-miss as to how well it works in any particular.hardware configuration.

Sleeping VM's can be tricky too. It's best to stop or hibernated. Then you could wake the VM through my libvirt wake on lan plugin. It monitors wake on lan packets on the network and will start a VM if the packet contains the mac of the VM. My question would be What is your goal? Save money on power or hardware. Also how many other device need access to your storage pool?
July 2, 201610 yr How does one turn on wake on lan for a network adapter in a VM? I'm currently using the NetKVM drivers for my Win10 VM and don't have a Power Management tab because of which (Win10 Pro x64). Should I change the adapter to a E1000 for the option to appear?

July 2, 201610 yr K, already did that. Generally speaking with WOL in Windows, you have to set the NIC to be allowed to be woken up in the power management tab. Thought I might be missing something since the tab doesn't exist with the virtio drivers.

Thought I might be missing something since the tab doesn't exist with the virtio drivers. Windows has no clue about the WOL packet, it's being parsed by the plugin, which in turn runs the virsh command to start the VM. The VM is dead as far as networking is concerned until a virsh command starts it. A shut down guest will be set to power on when you send a properly formed WOL packet with the MAC address of the guest virtual NIC.
