Hi,
The new qemu gdbstub in recent qemus/kvms is really nice and a
big improvement over earlier ones. Thank you.
I'm using qemu-kvm-0.10.6 on the plain Linux 2.6.30 KVM on VT.
One problem I noticed is that I cannot step on another CPU thread
than where it stopped.
e.g.
Ctrl-C
(stopping on thread 1)
(gdb) thread 2
(gdb) step
...
I come back to thread 1 after the step
On native gdb with multiple threads that seems to work.

You need vCont support in the gdbstub, and this feature is now finally
merged into 0.11. So qemu-kvm-0.11-rcX should be what you want.
