On a Linux* system, QEMU runtime may be slow if the kvm kernel module is not enabled.
To check if the kvm module is enabled:
- open a terminal console and run the command:
$ lsmod |grep kvm
- If the output is not similar to what you see below, you need to insert the kvm-intel kernel module manually.
kvm_intel 42019 0
kvm 256808 1 kvm_intel
To enable the kvm-intel kernel module manually, please follow these steps:
- Enable the Intel® Virtualization technology in bios and reboot. Normally it is in the Security setting. You may be required to shutdown power and restart the machine after change.
- Boot the Linux* system, open a terminal console, execute the following command:
$ sudo modprobe –i kvm-intel
- After step 2, the command "$ lsmod |grep kvm" output should show the kvm-intel module.
You may need to upgrade your graphics card driver to the latest version that supports OpenGL* acceleration.
