Hi maintainers,

I found there is an issue when 'xm save' a pvm guest. See below:

When I do save then restore once, CPU(%) in xentop showed around 99%.
When I do that second time, CPU(%) showed 199%

top in dom0 showed:
    PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
   20946 root      18  -2 10984 1284  964 S 19.8  0.3   0:48.93 block
   4939 root      18  -2 10984 1288  964 S 19.5  0.3   1:34.68 block

I could kill the block process, then all look normal again.

xen and xen-tools are both generated with xen-unstable.
I tried xl, but it segfault.
I also tried ovm3.1.1(xen-4.1.2-18.el5.1 and xen-tools-4.1.2-18.el5.1),
can't reproduce.

Did anybody see similar issue before? Any fix already there?
thanks
