+ QEMU CPU Compatibility Under KVM
+
+
+ By default, the QEMU build compiles for and targets 64-bit and x86
+ Intel Core2
+ Duo processors and 32-bit x86
+ Intel Pentium
+ II processors.
+ QEMU builds for and targets these CPU types because they display
+ a broad range of CPU feature compatibility with many commonly
+ used CPUs.
+
+
+
+ Despite this broad range of compatibility, the CPUs could support
+ a feature that your host CPU does not support.
+ Although this situation is not a problem when QEMU uses software
+ emulation of the feature, it can be a problem when QEMU is
+ running with KVM enabled.
+ Specifically, software compiled with a certain CPU feature crashes
+ when run on a CPU under KVM that does not support that feature.
+ To work around this problem, you can override QEMU's runtime CPU
+ setting by changing the QB_CPU_KVM
+ variable in qemuboot.conf in the
+ Build Directory's
+ deploy/image directory.
+ This setting specifies a -cpu option
+ passed into QEMU in the runqemu script.
+ Running qemu -cpu help returns a list of
+ available supported CPU types.
