Using QEMU for MeeGo development requires that your system be capable of VT support and hardware accelerated graphics. The following sections describe the steps to check for support on your platform.
Contents |
Your system must have support for virtualization to enable the QEMU virtual machine to accelerate graphics performance using the platform hardware. To check for VT support, run the following from a terminal. It should output something.
$ egrep '^flags.*(vmx|svm)' /proc/cpuinfo
Any output is success. Here's an example:
flags : fpu vme de pse tsc msr pae mce cx8 apic mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe lm constant_tsc arch_perfmon pebs bts pni dtes64 monitor ds_cpl vmx smx est tm2 ssse3 cx16 xtpr pdcm sse4_1 lahf_lm tpr_shadow vnmi flexpriority
Check that the kvm_intel or kvm_amd modules are loaded:
$ lsmod | grep kvm kvm_intel 43816 0 kvm 164576 1 kvm_intel
If the module is not loaded, load it as follows:
$ sudo modprobe kvm_intel
$ sudo modprobe kvm_amd
If the kvm modules are not available or fail to load, VT may be disabled in the BIOS.
Reboot your system, go into the BIOS, and enable VT.
Check that graphics acceleration is enabled on the host hardware:
$ glxinfo | grep "renderer string"
Good output: OpenGL renderer string: Mesa DRI ...
Bad output: OpenGL renderer string: Software Rasterizer
If you get the bad output (software) then acceleration is not fully enabled, your graphics driver might not be capable, and QEMU performance will be poor.
