For optimal performances, use 16 bit -color depth in the guest and the host OS. - -When using a 2.6 guest Linux kernel, you should add the option -@code{clock=pit} on the kernel command line because the 2.6 Linux -kernels make very strict real time clock checks by default that QEMU -cannot simulate exactly. - -When using a 2.6 guest Linux kernel, verify that the 4G/4G patch is -not activated because QEMU is slower with this patch. The QEMU -Accelerator Module is also much slower in this case. Earlier Fedora -Core 3 Linux kernel (< 2.6.9-1.724_FC3) were known to incorporate this -patch by default.
