So the issue
We can know the guest is panicked when the guest runs on xen.
But we do not have such feature on kvm.
Another purpose of this feature is: management app(for example:
libvirt) can do auto dump when the guest is panicked. If management
app does not do auto dump, the guest's user can do dump by hand
We can know the guest is panicked when the guest runs on xen.
But we do not have such feature on kvm.
Another purpose of this feature is: management app(for example:
libvirt) can do auto dump when the guest is panicked. If management
app does not do auto dump, the guest's user can do dump by hand
