Re: [libvirt] [PATCH 2/8] Introduce virQEMUCapsDeprecated array

To prevent domains started with older libvirtd from disappearing, we need to be able to parse the string representation of QEMU capabilities, even if we no longer use them in the code. Put those in a separate array where we won't bother with enum constants.
