[Bug 1906156] Re: Host OS Reboot Required, for Guest kext to Load (Fully)

[Russell Morris]

That makes sense, no issue at all. So I cloned from git (v5.2.0-rc3),
built, installed. All good so far :-). But then I tried to modify the
"emulator" in virt-manager, point to this build => I get the error,

Error changing VM configuration: internal error: Failed to start QEMU
binary /usr/local/bin/qemu-system-x86_64 for probing: libvirt:  error :
cannot execute binary /usr/local/bin/qemu-system-x86_64: Permission
denied

Thoughts? I have run into this before (without finding a fix sadly) -
thinking it's apparmor related somehow?

Thanks!

Title:
  Host OS Reboot Required, for Guest kext to Load (Fully)

Status in QEMU:
  Incomplete

Bug description:
  Hi,

  Finding this one a bit odd, but I am loading a driver (kext) in a
  macOS guest ... and it works, on the first VM (domain) startup after a
  full / clean host OS boot (or reboot). However, if I even reboot the
  guest OS, then the driver load fails => can be "corrected" by a full
  host OS reboot (which seems very extreme).

  Is this a known issue, and/or is there a workaround?

  FYI, running,
  QEMU emulator version 5.0.0 (Debian 1:5.0-5ubuntu9.1)
  Copyright (c) 2003-2020 Fabrice Bellard and the QEMU Project developers

  This is for a macOS guest, on a Linux host.

  Thanks!
