Yes, I did try that, this is how I found out that on my system it is not possible to cleanly shut down VMs that hold PCI devices. If I try shutting down sys-net the VM Manager hangs for a few minutes, then the entire system stops responding then the machine gets killed, then VM manager throws an exception and then system becomes responsive again. After setting pci_e820_host to False I can cleanly shutdown sys-net and sys-usb just like any other VM. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
