[libvir] How to seek a running QEMU instance

Hi,
I have the following question. How can virsh (or, more accurately, libvirt)
detect a running QEMU vm, when latter was already started? For example, I
have got the following:

[aspsk at localhost Server-4.0.1]$ qemu -hda Server-4.0.1.img -m 256 &
[1] 12001
[aspsk at localhost Server-4.0.1]$ Could not configure '/dev/rtc' to have a
1024 Hz timer. This is not a fatal
error, but for better emulation accuracy either use a 2.6 host Linux kernel
or
type 'echo 1024 > /proc/sys/dev/rtc/max-user-freq' as root.
Could not open '/dev/kqemu' - QEMU acceleration layer not activated: No such
file or directory
Could not open '/dev/qvm86' - QEMU acceleration layer not activated: No such
file or directory

[aspsk at localhost Server-4.0.1]$ sudo virsh -c qemu:///system list --all
 Id Name                 State
----------------------------------

[aspsk at localhost Server-4.0.1]$
