But when I try to do on nightwish : $ wget www.qemu.org The opeth QEMU makes a segfault : "11586 Segmentation Fault" This phenomenon is not always present... If the Segfault does not appear, nightwish cannot enable a connection with internet :( Thanks Vince Which version of QEMU did you use? Can you still reproduce this issue with the latest version of QEMU? [Expired for QEMU because there has been no activity for 60 days.]
