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: * Rebased to version 2.3.0-rc2 * Don't install ksm services as executable (bz #1192720) * Skip hanging tests on s390 (bz #1206057) * CVE-2015-1779 vnc: insufficient resource limiting in VNC websockets decoder (bz #1205051, bz #1199572) -------------------------------------------------------------------------------- References: [ 1 ] Bug #1199572 - CVE-2015-1779 qemu: vnc: insufficient resource limiting in VNC websockets decoder https://bugzilla.redhat.com/show_bug.cgi?id=1199572 -------------------------------------------------------------------------------- This update can be installed with the "yum" update program.
