Is anyone else experiencing a nearly useless qemu experience with the
latest versions?
I'm running -CURRENT from yesterday, and the latest qemu port (and kqemu).
These combinations segfault:
Anything with the -vnc option, when disconnecting the vnc viewer, will
segfault:
sudo qemu -hda /alt/images/fs.img -hdb /alt/images/swapfile -net nic
-net tap -snapshot -vnc :1 -serial /dev/ttyv8 -kernel-kqemu
This used to work nicely, now it dies when I connect to port 1111:
sudo qemu -hda /alt/images/fs.img -hdb /alt/images/swapfile -net nic
-net tap -snapshot -serial telnet::1111,server,nowait -std-vga -monitor
stdio -full-screen -kernel-kqemu
Which, when it dies, ktrace shows me:
