Re: [pve-devel] [PATCH 0/7] Work around QEMU 5.2 windows incompatibility

[Fabian Ebner <f.ebner@proxmox.com>]

Didn't follow this issue too closely, but what about restoring a 
pre-QEMU-ACPI-patch Windows VM backup in a post-QEMU-ACPI-patch world? 
Those would need to get pinned as well, right? Doing the pinning itself 
on restore shouldn't be difficult, but a good way to detect when it's 
needed is needed.
