Re: [libvirt] How to connect to console of domain on PowerPC?

For instance, /usr/bin/qemu-system-ppc -name demo -M ppce500v2 -enable-kvm -m 256 -nographic -kernel /media/ram/uImage -initrd /media/ram/ramdisk -append "root=/dev/ram rw console=ttyS0,115200" -serial tcp::4445,server Then to run 'telnet 10.193.20.xxx 4445' could connect the guest. The temporary workaround is not add '-device' string after '-serial' option.
