Hi,
We test VirtualDomain on Xen.(at RHEL5.5)
But, a problem is taking place when stop processing is carried out somehow or
other.
VirtualDomain_Status carried out by stop processing returns "no state" at
considerably high frequency.
For this problem, it is worked to destroy the guest(VM).
When VirtualDomain_Status gives back a right state, there is not the problem.
However, this problem happens in Xen environment, but does not occur in the KVM
environment.
We hope for the following improvement in the case of the Xen environment.
And we wish a guest(VM) is stopped definitely.
* When "no state" was provided by VirtualDomain_Status, carry it out again.
* And, based on a stable state, carry out processing
--------------------------
