Takashi Kajinami dfd96286a2 libvirt: Disable VMCoreInfo device for SEV-encrypted instances ...

When VMCoreInfo device is enabled, the QEMU fw_cfg device in guest OS
requires DMA between host OS and guest OS through the device. However
DMA is prohibited when guest memory is encrypted using SEV, and
the attempt results in kernel crash.

Do not add VMCoreInfo when memory encryption is enabled.
