QEMU KVM Setup for t1024rdb on Ubuntu VM

[zhicheng1]

Hi, I am trying to setup QEMU with KVM  for t1024rdb on ubuntu(14.04) VM running on my windows machine.  I followed the steps in the document QorIQ-SDK-2.0-IC-Rev0.pdf. I  have been able to complete the fsl-image-virt and have verified that the linux kernel has all the required features enabled.

I also followed the instructions in section  12.2.3.6. I get some errors when I run command as follow

"------------------------------

"kvm" accelerator not found.

No accelerator found!

"----------------------------

the command log: 

$ ls -1 /var/lib/hugetlbfs/

Could you please tell me how to resolve this error?

I change the config file of the QEMU to enable "CONFIG_KVM", but compilation failure, so remove the option "enable-kvm" and change QEMU command as below:

sudo qemu-system-ppc -m 512 -M ppce500 -cpu e500mc -no-reboot -nographic -chardev stdio,id=con,mux=on -mon chardev=con,mode=readline -serial chardev:con -kernel uImage_new -initrd rootfs.ext2.gz -append "root=/dev/ram rw console=ttyS0,115200 ramdisk_size=1000000"

it can load kernel but fail to run the init command in the rootfs, the error log as below  and I create a question to track it.

Hello,

No accelerator found means that is not found the emulator itself in the code, in this case you have to compile the code and check this situation.

Hi,

Do you mean " Building Linux with KVM "? I have done it but not work. Could you give me some suggestions to check it? 

Thanks,
