[libvirt] libvirt-1.0.3 vs qemu-1.4

Hi guys, I used to go through libvirt (1.0.3) use cases with qemu-1.0 + linux-3.0.43. Recently I tried Linux-3.8.4 + qemu-1.4. But it can't start qemu domain. --------------------------------- root@p1022ds:~# virsh version Compiled against library: libvirt 1.0.3 Using library: libvirt 1.0.3 Using API: QEMU 1.0.3 Running hypervisor: QEMU 1.4.0 root@p1022ds:~# cat test.args /usr/bin/qemu-system-ppc -name test -M mpc8544ds -enable-kvm -m 256 -nographic -kernel /media/ram/uImage -initrd /media/ram/ramdisk -append "root=/dev/ram rw console=ttyS0,115200" -serial pty root@p1022ds:~# virsh domxml-from-native qemu-argv test.args >test.xml root@p1022ds:~# virsh define test.xml Domain test defined from test.xml root@p1022ds:~# virsh start test error: Failed to start domain test error: internal error no assigned pty for device charserial0 --------------------------------- I don't know if it depends on qemu version or kernel config. Do you have any idea about this issue? Best Regards, Olivia
