I'm running Arch and updating recently has caused my VM to stop booting. Watching journalctl I see this when I try to start the VM:
"Feb 23 15:04:07 haze kernel: BUG: unable to handle kernel NULL pointer dereference at 00000000000000a8 Feb 23 15:04:07 haze kernel: IP: down_write+0x12/0x30 and some more. Full pastebin is here: https://pastebin.com/8u70XLWJ This happens when I try to start my domain (called "Win10Full"). When it occurs, virsh locks up -- if I'm in virsh and do "list" it sits indefinitely. If I ctrl-C at this point, "End of file while reading data: Input/output error" gets written to the log, and my host cannot be rebooted without a physical power cycle. There is nothing that gets written to /var/log/libvirt/qemu/Win10Full.log. I'm not sure how to proceed; I figured this mailing list would be the first place to start. Any suggestions? Thanks in advance, Will
