Other than the usual cleanup some new flags have been aded which I found useful enough to make permanent:

  1. Flag(s) [-avoidVirtio/-noVirtio] to use generic virtual hardware such as e1000e for guest Ethernet among other comprompises for special cases.

    • If you don't have the virtio ISO handy during installation or are booting a kernel/initrd directly without virtio drivers baked in, this is a savior.

  2. Flag(s) [-cputhreads / -showpairs / -showthreads / -showcpu]

    • To quickly show which host threads belong to what cores.

  3. Flag(s) [-ignorevtcon / -ignoreframebuffer / -leavefb / -leaveframebuffer / -leavevtcon]
    Optional workaround for kernel Bug 216475 on Nvidia cards.

    • At the moment, unbinding and rebinding vtcon0/1 may cause a null pointer dereference in fbcon.c with certain video drivers. True for kernel version 6.0.11 at least.
    • With this argument I can resume passing my GPU from guest to host indefinitely in a single boot but at the cost of my virtual consoles.
    • I like my virtual consoles though so hopefully this is fixed soon and this flag gets deprecated.

  4. Added -kernel, -cmdline and -initrd options for various realtime kernel hackery and testing

As for other general changes since the last tag:

  • Squashed vcpu pinning bug introduced in earlier commit (Had the ampersand in the wrong spot, damn)

  • -m can now also be used instead of -memory

  • Script no longer relies on brctl, bash now traverses /sys/class/net itself.

  • Hugepage arguments now also get calculated in the dry run

  • Script automatically increments its spice port if already in use
