QEMU (Quick EMUlator) it is a software that allows you to emulate systems x86, AMD64, PowerPC, MIPS e ARM.
QEMU v2.12.0: Download
Highlights include:
Spectre/Meltdown mitigation support for x86/pseries/s390 guests. For more details see:

Numerous block support improvements, including support for directly interacting with userspace NVMe driver, and general improvements to NBD server/client including more efficient reads of sparse files
Networking support for VMWare paravirtualized RDMA device (RDMA HCA and Soft-RoCE supported), CAN bus support via Linux SocketCAN and SJA1000-based PCI interfaces, and general improvements for dual-stack IPv4/IPv6 environments
GUI security/bug fixes, dmabufs support for GTK/Spice.
Better IPMI support for Platform Events and SEL logging in internal BMC emulation
SMBIOS support for “OEM Strings”, which can be used for automating guest image activation without relying on network-based querying
