    @stormi I'm also getting error on some VMs while trying to export a disk and also trying to even start some VMs from NFS (that were fine before). xo-server[565]: 2026-05-13T02:53:15.746Z xo:api WARN admin | vm.start(...) [2s] =!> XapiError: INTERNAL_ERROR(xenopsd internal error: Storage_error ([S(Illegal_transition);[[S(Activated);S(RO)];[S(Activated);S(RW)]]])) xo-server[565]: 2026-05-13T02:53:40.652Z xo:api WARN admin | vm.start(...)

    Hi @mdm, Here is the response from a SME 1- XO get the VM metadata through soap api and create the vm /network XO use the nbdkit + nbdkit-vddk package , connecting to each disk XO connect through NBD to nbdkit XO list the allocated blocks XO create the disk XO read the block and import the data into the disk (though a vhd or qcow2 stream depending on the size) 2- though XO. There is a lot of disk transform occuring here 3- not anymore, it was too brittle, especially on when the disk are locked or not. Also it was not scaling too well 4- see 3- + vddk transfer is overwhelmly faster that previous access through http, is compatible with VSAN and don't lock the disks.

    @nasheayahu Hello, I do this with a my homelab disk since I imported it from a physical machine: mkdir /srv/NAS xe sr-create type=udev sm-config:location=/srv/NAS name-label="NAS Disks" Then you make a symlink to the device: ln -s /dev/sda /srv/NAS/sda #although it might be better to use a stable identifier if you have multiple disks xe sr-scan uuid=<UUID of the udev SR> The disk will appear as a VDI in the SR that you can then plug to a VM. I also renamed the VDI [NOSNAP][NOBAK] NAS Drive [NOSNAP][NOBAK] instruct XO to not snapshot and export the disk in backups (since it can't). It's not passthrough, as in the disk is not directly given to the VM, but tapdisk (the process virtualizing storage) will give access to the whole disk to the guest, so it can mount any FS on it. The udevSR is usually used for plugging USB from what I could gather from existing code. But users in homelabs have been using it like this for a while. Though you will likely not have native performance level since it's not exactly passthrough.

    @Mathieu-L linstor n l was included in my original post. All nodes were updated to May 2026 Security and Maintenance Updates for XCP-ng 8.3 LTS, all nodes were restarted. May 2026 Updates #2 for XCP-ng 8.3 LTS was released, and a couple days later I installed on all hosts. No host restarted. When xen04 was restarted, that is when this issue happened. I had used systemctl restart linstor-controller here (https://xcp-ng.org/forum/post/105309) to restart the controller.
