QEMU enhancement tackles floating point errors in Fedora 23, promoting better reliability and safeguarding. Explore the specifics!
* vnc: avoid floating point exceptions (bz #1289541, bz #1289542)

Summary

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:

* vnc: avoid floating point exceptions (bz #1289541, bz #1289542)
