Currently the choice of whether to use nettle or gcrypt is
made based on what gnutls is linked to. There are times
when it is desirable to be able to force build against a
specific library. For example, if testing changes to QEMU's
crypto code all 3 possible backends need to be checked
regardless o

When encrypting/decrypting data, the plaintext/ciphertext
buffers are required to be a multiple of the cipher block
size. If this is not done, nettle will abort and gcrypt
will report an error. To get consistent behaviour add
explicit checks upfront for the buffer sizes.

This is the only thing which i e
If no IV is provided, then use a default IV of all-zeros
instead of crashing. This gives parity with gcrypt and
nettle backends.

OK but that's only if MQ is set. If now, we need to do

Current implementation depends on the order of resets getting triggered.
If a cpu reset is triggered after the ipl device reset, the CPU is stopped and
the VM will not run. In fact, that hinders us from converting the ipl device
into a TYPE_DEVICE. Let's change that by ma
From: David Hildenbrand
The cmma reset is per VM, so we don't need a cpu object. We can
directly make use of kvm_state, as it is already available when
the reset is called. By moving the cmma reset in our machine reset
function, we can avoid a manual reset handler.
