    Chuckz said: For example, important security features in Windows 11 such as core isolation do work on my Windows 11 guests... Edit: That is a typo. I meant to say that core isolation does not work on my Windows 11 guests, and I suspect it is because of the lack of the NV feature in Xen and XCP-ng. So my point is that over time, you can forget about running Windows on any other hypervisor except Hyper-V if it is true that we can never use NV in production.

    @poddingue there is a notion of appliance too (group of VMs) https://docs.xcp-ng.org/appendix/cli_reference/#appliance-commands where you can start/stop a group of VMs, never tried it, doesn't seem to have a boot order in the vAPP neither

    @dthenot said: @ccooke Hello, You should be able to make the XOSTOR SR work again if you update sm and sm-fairlock on the other hosts. yum update sm sm-fairlock Then you should be able to re-plug the SR on the master and proceed with the RPU. Hello, Had the same problem, the command resolved the issue. It needs to be run on every host. Everything is working fine again. However, I had to complete the pool update manually.
