Hi,
I tried to use kvm on TWR-LS1021A according to QorIQ SDK 1.8 Documentation.
I worked on QorIQ SDK 1.8.
I used fsl-image-full as host rootfs and fsl-image-virt as guest rootfs.
I configured kernel parameters too.
I tried to start qemu-kvm as follows:
`qemu-system-arm -enable-kvm -m 512 -nographic -cpu host -M virt -kernel /boot/zImage -serial tcp::4446,server,telnet -initrd /boot/rootfs.ext2 -append 'root=/dev/ram console=ttyAMA0 earlyprintk' -monitor stdio`
But it outputed only as follows:
```
QEMU 2.2.0 monitor - type 'help' for more information
(qemu) QEMU waiting for connection on: disconnected:telnet::4446,server
```
I tried to connect 0.0.0.0:4446 using telnet, but it failed.
I also tried to start guest OS by libvirt as follows:
```
echo "/usr/bin/qemu-system-arm -name kvm -smp 2 -enable-kvm -m 512 -nographic -cpu host -machine type=virt -kernel /boot/zImage -serial pty -initrd /boot/rootfs.ext2.gz -append 'root=/dev/ram0 rw console=ttyAMA0 rootwait earlyprintk' " > kvm.args
virsh domxml-from-native qemu-argv kvm.args > kvm.xml
virsh define kvm.xml
virsh start kvm
```
But it failed:
```
error: Failed to start domain kvm
error: operation failed: domain is no longer running
```
Why did such errors occurred? Are there any methods to debug this error?
