I am having the same problem. I am new to unRAID and built an AMD system and enabled all the AMD virtualization settings I could find in the BIOS. As soon as I start the VM, my unRAID server becomes unstable and unresponsive. I can't even do a clean shut down from the powerdown plugin via SSH. I am unable to shut down the VM - even commands from CLI hang. The only thing I could do was do a hard reset. I tried a Windows 10 and Ubuntu 14.04 VM. I thought maybe I had bad settings on the VMs - I tried Host Passthrough and Emulated CPU Modes, I tried different Machine type settings - nothing has worked so far. If anyone has any suggestions, I'd really appreciate it! tail -100 /var/log/libvirt/libvirtd.log 2016-05-09 20:02:45.771+0000: 5969: info : libvirt version: 1.3.1 2016-05-09 20:02:45.771+0000: 5969: info : hostname: beast 2016-05-09 20:02:45.771+0000: 5969: warning : virHookCheck:135 : Non-executable hook script /etc/libvirt/hooks/qemu 2016-05-09 20:06:27.703+0000: 5969: error : virNetDevSendEthtoolIoctl:3191 : ethtool ioctl error: No such device 2016-05-09 20:06:27.715+0000: 5969: error : virNetDevSendEthtoolIoctl:3191 : ethtool ioctl error: No such device 2016-05-09 20:06:27.727+0000: 5969: error : virNetDevSendEthtoolIoctl:3191 : ethtool ioctl error: No such device 2016-05-09 20:06:27.741+0000: 5969: error : virNetDevSendEthtoolIoctl:3191 : ethtool ioctl error: No such device 2016-05-09 20:06:29.040+0000: 5969: error : virNetDevSendEthtoolIoctl:3191 : ethtool ioctl error: No such device 2016-05-09 20:06:29.052+0000: 5969: error : virNetDevSendEthtoolIoctl:3191 : ethtool ioctl error: No such device 2016-05-09 20:06:29.054+0000: 5969: error : virNetDevSendEthtoolIoctl:3191 : ethtool ioctl error: No such device 2016-05-09 20:06:29.068+0000: 5969: error : virNetDevSendEthtoolIoctl:3191 : ethtool ioctl error: No such device 2016-05-09 22:06:54.911+0000: 5970: warning : qemuDomainObjTaint:2223 : Domain id=1 name='Ubuntu' uuid=b8345267-8517-5b86-3396-234afc63ab9b is tainted: high-privileges 2016-05-09 22:06:54.911+0000: 5970: warning : qemuDomainObjTaint:2223 : Domain id=1 name='Ubuntu' uuid=b8345267-8517-5b86-3396-234afc63ab9b is tainted: host-cpu 2016-05-09 22:10:47.006+0000: 5973: error : qemuAgentSend:898 : Guest agent is not responding: Guest agent not available for now 2016-05-09 22:11:03.323+0000: 5973: error : virProcessKillPainfully:398 : Failed to terminate process 13788 with SIGKILL: Device or resource busy 2016-05-09 22:36:13.695+0000: 5969: error : virNetSocketReadWire:1613 : End of file while reading data: Input/output error 2016-05-09 22:36:20.810+0000: 5971: error : virProcessKillPainfully:398 : Failed to terminate process 13788 with SIGKILL: Device or resource busy 2016-05-09 22:37:49.811+0000: 5970: error : virProcessKillPainfully:398 : Failed to terminate process 13788 with SIGKILL: Device or resource busy 2016-05-09 22:40:55.829+0000: 5972: warning : qemuDomainObjBeginJobInternal:1668 : Cannot start job (modify, none) for domain Ubuntu;

Rich, When I built my unRAID system, I had some crashes and determined that it was due to BIOS modifications I had made - specifically CPU overclocking. After I removed the overclocking, it's been running great. If you have modified your BIOS it could explain why you are not having issues running while in the BIOS versus crashing after booting into unRAID. Even if you haven't made BIOS changes, you may want to investigate BIOS settings that may improve stability/performance in unRAID - for example virtualization setting for CPU. Just wanted to share my experience. Hope this helps. Dave
