Liu, Thanks for the suggestions and your time trying out on an 8548...tried your qemu binary ran into the same result (hang) - which meant most likely it was not a qemu issue... looked around again realized it was my bad - had built the guest kernel with the KVM and VIRT config options. Rebuilt the guest without any KVM/VIRT options, saw the kernel boot up - saw a hang when it was trying to mount the ramdisk - increased some free space on the ramdisk - which helped for it to mount rootfs and boot further up - saw a kernel panic for out of memory - increased the memsize for guest from 64 to 128 did not see the kernel panic again - did not see the login prompt initially - changed to ttyS0 in ltib as you had mentioned - booted all the way up and able to login to the guest from my telnet session I'll try to get networking configured next..thanks for all your help - appreciate that. -rahul -----Original Message----- From: Liu Yu-B13201 [mailto:Yu.Liu@xxxxxxxxxxxxx] Sent: Tuesday, March 17, 2009 10:46 PM To: Rahul Kulkarni; Hollis Blanchard Cc: kvm-ppc@xxxxxxxxxxxxxxx Subject: RE: qemu ppcemb illegal instruction Rahul, I tested qemu on 8548 target today. It works fine. Here is my command: ./qemu-system-ppcemb -enable-kvm -m 64 -nographic -M mpc8544ds -kernel uImage -initrd ramdisk -L . -append "root=/dev/ram rw console=ttyS0,115200" -serial tcp::4444,server You also can remove "-serial tcp::4444,server", but will lose the monitor. It's werid you got no output. You can send me the qemu binary so that I can try to find the problem. And don't forget to tell me the latest qemu commit, so that I can know the code. > -----Original Message----- > From: Rahul Kulkarni [mailto:rkulkarn@xxxxxxxxxxxxxxxxxxx] > Sent: Wednesday, March 18, 2009 5:33 AM > To: Liu Yu-B13201; Hollis Blanchard > Cc: kvm-ppc@xxxxxxxxxxxxxxx > Subject: RE: qemu ppcemb illegal instruction > > /bin # ./qemu-system-ppcemb -enable-kvm -m 64 -nographic -M > mpc8544ds -kernel / > tmp/uImage.8544 -initrd /tmp/rootfs.ext2.gz.small -L You need to gunzip rootfs.ext2.gz.small > /usr/local/share/qemu -app > end "root=/dev/ram rw" -serial tcp::4444,server > QEMU waiting for connection on: tcp:0.0.0.0:4444,server > -- To unsubscribe from this list: send the line "unsubscribe kvm-ppc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
