[pve-devel] [PATCH qemu] api: qemu: create: default cpu to x86-64-v2-AES

[Shannon Sterz]

note that the gui's default is a bit "fake". it pre-sets the field to
`x86-64-v2-AES`, but if you click the little "x" next to it, the field
will be cleared and if you submit the form like that the default ends up
being `kvm64` again. this happens because the final config file does not
specify a cpu type in this case and, hence, the old default is used for
compatability reasons.

so, this effectively removes the ability to set *no* cpu type via the
cli if i'm not mistaken. might be worth considering.
