Name : qemu
Product : Fedora 28
Version : 2.11.1
Release : 3.fc28
URL : http://www.qemu.org/
Summary : QEMU is a FAST! processor emulator
Description :
QEMU is a generic and open source processor emulator which achieves a good
emulation speed by using dynamic translation. QEMU has two operating modes:
* Full system emulation. In this mode, QEMU emulates a full system (for
example a PC), including a processor and various peripherials. It can be
used to launch different Operating Systems without rebooting the PC or
to debug system code.
* User mode emulation. In this mode, QEMU can launch Linux processes compiled
for one CPU on another CPU.
As QEMU requires no host kernel patches to run, it is safe and easy to use.

Update Information:
New CPU features for speculative store bypass (CVE-2018-3639) On Intel x86
hosts, the "ssbd" feature must be explicitly added to any virtual machines that
are not using host-passthrough/host-model CPU setup. NB this requires new
microcode too, which is not yet available in Fedora microcode_ctl RPMs. On AMD
x86 hosts, the "virt-ssbd" feature must be explicitly added to any virtual
machines that are not using host-passthrough/host-model CPU setup. There is no
microcode dependency for AMD as this is a virtualized CPUID feature. In both
cases, kernel >= 4.16.10-301 is required on the host and guest in order to
activate the fix.
