[pve-devel] [PATCH-SERIES qemu-server/manager 0/7] VM CPU flags: introduce vendor-agnostic 'nested-virt' CPU flag

The flag will automatically resolve to the flag required for the
current CPU on the host. The 'nested-virt' flag takes precendence over
the CPU-specific flag for nesting which might already be present with
custom CPU models. In that case, a warning is printed.

Moves the cpu flag descriptions to qemu-server and introduces an API
endpoint for querying. Could later be extended with further
information, for example, which flags are actually supported on the
current host (some are specific to vendor or CPU).

Dependency and build-dependency bump pve-manger -> qemu-server needed!

qemu-server:

Fiona Ebner (4):
  cpu config: style fix: avoid multiline post-if expressions
  cpu config: style fix: avoid overly long ternary conditional
    expression
  api: add endpoint for querying available cpu flags
  cpu config: introduce vendor-agnostic 'nested-virt' CPU flag
