Chris, I just tried a simple test this way:
./x86_64-softmmu/qemu-system-x86_64 -device virtio-serial-pci -device
virtserialport -S -monitor stdio -nographic
and it didn't crash for me. This was with qemu.git. Perhaps you can
try in a similar way.
I just tried it with the "stable-1.4" branch from upstream with my first
patch added on.
Anyway, it seems to boot up okay, which is better than what I was
getting before.
Turns out I spoke too soon. With the patch applied, it boots, but if I
try to do a live migration both the source and destination crash. This
happens for both the master branch as well as the stable-1.4 branch.
If I back out the patch, it works fine. If I leave the patch in and
disable kvm acceleration it works fine.
I'm running the source as
/tmp/qemu-system-x86_64-upstream -machine accel=kvm -m 1000
test-cgcs-guest.img -device virtio-serial -chardev
socket,path=/tmp/foo,server,nowait,id=foo -device
virtserialport,chardev=foo,name=myfoo -monitor stdio
and the dest as
/tmp/qemu-system-x86_64-upstream -machine accel=kvm -m 1000
test-cgcs-guest.img -device virtio-serial -chardev
socket,path=/tmp/foo,server,nowait,id=foo -device
virtserialport,chardev=foo,name=myfoo -monitor stdio -incoming tcp:0:4444
and I'm triggering the migration with
migrate -d tcp:localhost:4444
On the dest side monitor I get:
(qemu) qemu: warning: error while loading state section id 3
load of migration failed
I managed to get gdb working, but it's not very helpful. With gdb
attached to the destination process I just get:
[Thread 0x7f760f6dc700 (LWP 15328) exited]
[Inferior 1 (process 15326) exited normally]
