Hi sorry on mobile so replying top. I've got some 2016 guests running close to 12 months uptime. Just some ideas below: RAM allocation a little low for 2016 so bump that a little. I use zvol for ahci storage with 4k blocks but have run 8k blocks as well. MSSQL doesn't like anything more than 4k. Swap out the nic e1000 for virtio. You'll get better throughput without emulation. Drivers are available in places but I can provide you the iso version that we use in production. I think this is what is causing you issues. Cheers. Jason.
