This is the default NIC emulated by QEMU.

I don't use.

We have EXT4 which can work with both ext2 and ext3. Besides that I
don't use any ext filesystems currently as root under QEMU is mounted
over 9P.

There is no leds to control from under QEMU.

There is no backlight to control under QEMU.

We have VIRTIO_GPU to be used under QEMU.

QEMU does not support joysticks and I do not need it at all.

Under QEMU we have network support via VIRTIO_NET.

There is no need to load firmware under qemu.

No need to load CPU microcode under QEMU.

We are running "QEMU Virtual CPU", not Intel.

There is no possibility a virtual CPU could get overheaten on something
similar.

+ enable CUSE (this is needed to test OSSPD).

CONFIG_KASAN_STACK=1 is selected automatically on GCC:

	git.kernel.org/linus/6baec880d7

Debian's cpuburn was removed from the distribution.

To be able to use e.g. bpftrace.

To debug fuse itself.

Inspired by gendiff from RPM. Defaults to .nxd0 suffix but suffix can be
set explicitly. See details in script header how to use & make local
changes so gendiff-nxd0 works.

Иначе без модулей не работает сеть.

То, что было =m, не включал (и проверил 95%) что модули не загружены.
То, что было =y - включил.

The same one as using on lab.nexedi.com backend.

Currently only oldconfig-extracted from latest mini64.conf.
Will adjust in following commits.

Spot in comments to recent LWN article.

- nice -19 for cpu
- ionice with idle scheduling class

From 2010. Needs fixing with recent Git. And better be upstreamed
