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.

Can anyone give some clew about how to fix this? Thanks:-)

s/clew/clue/

I presume you mean a stub qemu domain? At a very minimum, you need the stub domain booted completely *before* starting windows.

The windows VM is crashing because of:

(d1) [ Â135.566884] *** HVMLoader assertion '(devfn != PCI_ISA_DEVFN) || ((vendor_id == 0x8086) &&Â

(d1) [ Â135.566968] (device_id == 0x7000))' failed at pci.c:112

(d1) [ Â135.567012] *** HVMLoader crashed.

because the stub domain is emulating a PCI bus at the point at which HVMLoader is looking for one.

Sorry. "is not emulating a".
