[libvirt] [PATCH 0/7] Update systemtap probing

[lvroyce]

I believe enable systemtap will be very helpful for debugging.But I 
encountered belowing  error when enable systemtap support:

*emantic error: probe point mismatch at position 0 (alternatives: __nfs 
__scheduler __signal __tcpmib __vm _linuxmib _signal _sunrpc _syscall 
_vfs begin begin(number) end end(number) error error(number) generic 
ioblock ioblock_trace ioscheduler ioscheduler_trace ipmib irq_handler 
kernel kprobe kprocess linuxmib module(string) nd_syscall netdev never 
nfs nfsd perf process process(number) process(string) procfs 
procfs(string) scheduler scsi signal socket softirq stap staprun sunrpc 
syscall tcp tcpmib timer tty udp vfs vm workqueue): identifier 'libvirt' 
at :130:7 while resolving probe point libvirt.event_poll.run
         source: probe libvirt.event_poll.run {
                       ^
Pass 2: analysis failed.  Try again with another '--vp 01' option.

*Here's my environment:
*    Ubuntu 11.04 amd64
     configured --with-dtrace --enable-shared=no --with-pic(fPIC flag 
also tried)
     dtrace installed and compile probe with dtrace -64*

Would somebody pls give me some advice with this systemtap issue?
Thanks a lot!
