Any thoughts or ideas on where to look next? Not only do they run very sluggish, they take about an hour to reboot. I am completely our of ideas on what to check next and what to look at to increase their performance. The only errors I ever get are VSS related, and its always because VSS is timing out due to the sheer slowness of the guests. Both came back without errors.Įvent viewer shows really no relevant errors (at least that I can find). I have also ran SFC and DISM hoping I could find a resolution to why its being so slow. They now average a read/write speed of about 375Mbps.
Originally the disk read write speeds were pretty bad for the virtual disks (each guest has 2) but I was able to optimize that by moving stuff around on the host and converting to fix disks rather than dynamic etc. I have ensured abundant ram and CPU resources available and are not coming close to their caps. Now both the guests boot and appear to work fine, but they are both incredibly slow. I had to do some more work to get it to work perfectly, but I got it there. After a weekend of crying and fixing it booted and all the data I cared about was there. IE the parent file was recovered from months prior, and the avhdx file was from a recent recovery. I went into the after math and was able to restore it from some avhdx checkpoint files, and some old versions of their parent file. Someone else had made an attempt to restore it, and had failed pretty badly accidentally deleting all the data (Or so they thought). It has two guest VMs, one DC running windows server 2016 Essentials, and one application server running windows Server 2016 Standard.Ī while ago the server had crashed due to windows updates. It is a single host running windows Server 2016 Essentials (not domain joined) and running Hyper-V. I am not sure if this is a virtualization issue or more of Windows itself, so I can move/re-post if necessary.
