I have what I think is the same problem. Windows XP guest on jaunty x86_64 host: $ kvm -hda windows_xp.qcow2 -boot c -m 1024 -localtime -serial /dev/ttyS0
Setting the baudrate on Windows also modifies the baudrate on the jaunty host, but no data is transferred. When I run: $ qemu -hda windows_xp.qcow2 -boot c -m 1024 -localtime -serial /dev/ttyS0 Could not open '/dev/kqemu' - QEMU acceleration layer not activated: Permission denied all works well, though very slowly ! -- ttyS0 pass through in guest running in KVM doesn't work and eventually hangs https://bugs.launchpad.net/bugs/370270 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
