[Xen-devel] [PATCH] HVM qemu-pid in xm-test output log

[Rick Gonzalez <rcgneo@xxxxxxxxxx>]

This patch creates a new entry in "xenstored" under 
"/local/domain/<id>/" called "qemu-pid" containing the actual pid number 
for the HVM-domain created.
Then, xm-test probes that entry to include it in it's output log. This 
is usefull for debugging purposes.
