Xen project Mailing List

Hi, everyone.

I'm trying to run a Windows HVM vm with stub domain in xenserver-6.5, whose internal xen version is xen-4.4-xs88306. After I started the vm, both the vm and its corresponding stub domain crashed. Here is the related content in hypervisor.log. The domain ID of the windows vm is 1, and the stub domain's id is 2.
