Package: linux-source-6.1 Version: 6.1.106-3 Hi! One patch is missing from the kernel source, causing modern guest OSes to be broken in a nested environment. Affected Guest (for example): ESXI 8. with AMD CPUs ESXI 8.0 can boot, but any VM doesn't boot/work inside the nested environment. The guest VMs are work inside nested environment after applying the missing patch.
