I've experienced this issue myself and I saw some people complaining about it on the mailing list. Sometimes Qubes takes forever to poweroff.
The issue is caused by the fact that for some unknown reason machines with PCI devices attached take forever to shutdown and sometimes need to be manually killed from within VM Manager. After manually killing them, the system will shutdown normally. So, here's the fix: In Dom0 run qvm-prefs -s sys-net pci_e820_host false Repeat that for sys-usb and any other machine that holds a PCI device. Your system should shut down normally after this. No, I don't know how or why this works but I know that it solved the issue on my machine. Explanation welcome. I'll add this to documentation once we have a confirmation that this is 100% reproducible. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
