Troubleshooting QEMU SDK

ErrorSolution
(Step 1) Downloading or unpacking the image gives errors.Ensure that the MD5SUM matches:
$ md5sum <image file>

The images are large so you might try a download program that handles connection interrupts, such as wget:

$ wget --continue <link to file>
(Step 5) Launching QEMU gives error:
Could not access KVM kernel module: No such file or directory
failed to initialize KVM 
Your system must have VT support and have the KVM modules loaded.
  1. Check for VT support. The following should output something:
  2. egrep '^flags.*(vmx|svm)' /proc/cpuinfo
    
  3. Check that the kvm_intel or kvm_amd modules are loaded:
  4. $ lsmod | grep kvm
    kvm_intel              43816  0 
    kvm                   164576  1 kvm_intel
    

    If needed, load the module:

    $ sudo modprobe kvm_intel
    
(Step 5) Launching never finishes; no MeeGo UI. A new window appears but it is just black. Title: QEMU (MeeGo)
(Step 5) Performance in QEMU is slow
Please check whether the host machine has the hardware graphic acceleration by running below command:
glxinfo|grep "renderer string"
