March 5, 20206 yr I changed domain share settings a few weeks ago and shut down one of my VM's a few days ago. When I tried to start it back up today I couldn't remote into it and I notice VNC Remote shows UEFI Interactive Shell. I then noticed it couldn't find the vdisk under cache folder so I pointed it to user and it still wouldn't start. I've now changed the domain share back to prefer, ran mover, pointed the VM back to cache, but it still will not start. I'm not sure what happened and how to resolve ... please find the XML, Diagnostics, and Log below and advise if you can see something I've missed... <?xml version='1.0' encoding='UTF-8'?> <domain type='kvm' id='2'> <name>001 -

March 5, 20206 yr What is your vdisk type? qcow2? raw? Are you sure you haven't changed vdisk type in the process when you changed the path? That is the most often issue with new user when changing vdisk on the VM template i.e. they don't know / check what vdisk type they are using.
March 5, 20206 yr Author I'm not sure. It's always confused me when setting up a new VM since I cannot see what my other VM's are set to in the basic config page so I suspect I stick with default which if I'm correct is raw. With regards to your comment, are you saying when the vdisk was moved and the VM was started the config would have changed from one to the other? FWIW - I've not changed any settings in the VM config and only changed the path of where the vdisk is located since it was moved from cache to user.

FWIW - I've not changed any settings in the VM config and only changed the path of where the vdisk is located since it was moved from cache to user. First check to make sure your vdisk file only exists under ONE of these possible paths: /mnt/cache/domains/001 - Windows 10/ /mnt/disk1/domains/001 - Windows 10/ /mnt/disk2/domains/001 - Windows 10/ ... and so on to the last disk Just ls each of the path. Does the vdisk exists under more than one path?
March 5, 20206 yr Author I've the vdisk under both /mnt/cache/domains and /mnt/user/domains. Should this be in both paths? What's the difference between user and cache paths? If I set the share to ONLY, the file exists only on the cache drive ... would user be a shortcut to (cache) or is user only for the array? If I set the share to Prefer and the cache fills up thus moving the file to the array, I believe cache path will fail whereas user will know its on the array but then will redirect to the cache when it's moved back?

March 5, 20206 yr Author I meant to say there's no domain folder under any of the /mnt/diskx folders but there is one under /mnt/user. Edited March 5, 20206 yr by bugsysiegals

Try creating a template from scratch with the same parameters to see if it boots. (note: you might also want to pick 4.2 instead of 3.0, which is very old). This is to eliminate a corrupt bios. Remove the virtio driver iso (i.e. leaving just the vdisk behind). This is to eliminate any interference by the boot sequence. Try changing the type from raw to qcow2. qcow2 and raw are the 2 most frequently used vdisk types. /mnt/user is the same as /mnt/cache if the vdisk is on cache.
March 5, 20206 yr Author FWIW - I have 2 other Windows 10 VM's which were not impacted. One has been running the entire time and the other has been offline for weeks but started up no issues. Should I still create some new VM's? Edited March 5, 20206 yr by bugsysiegals

March 5, 20206 yr Author Ok, I assume you mean to create a new VM from template and point it to the existing vdisk to see if I can get it to boot?
March 5, 20206 yr Author I've created 2 new VM's (qcow/raw) both as Machine: i440fx-4.2, no OS Install ISO, no VirtIO Drivers ISO, both with 2 network adapters for the 2 bridges I have setup and am using in my other VM's as well as the original. I then edit the configs and set Primary vDisk Location to Manual and select /mnt/user/domains/001 - Windows 10/vdisk1.img. Both times the VM boots to UEFI screen. FWIW - I noticed my other VM was using Machine 4.2 and I was considering to change this VM from 3.0 to 4.2 before restarting the other day. I don't recall if I actually tried it or not. but wanted to point this out in case it matters.
