晋太元中，武陵人捕鱼为业。缘溪行，忘路之远近。忽逢桃花林，夹岸数百步，中无杂树，芳草鲜美，落英缤纷。渔人甚异之，复前行，欲穷其林。 　　林尽水源，便得一山，山有小口，仿佛若有光。便舍船，从口入。初极狭，才通人。复行数十步，豁然开朗。土地平旷，屋舍俨然，有良田、美池、桑竹之属。阡陌交通，鸡犬相闻。其中往来种作，男女衣着，悉如外人。黄发垂髫，并怡然自乐。 　　见渔人，乃大惊，问所从来。具答之。便要还家，设酒杀鸡作食。村中闻有此人，咸来问讯。自云先世避秦时乱，率妻子邑人来此绝境，不复出焉，遂与外人间隔。问今是何世，乃不知有汉，无论魏晋。此人一一为具言所闻，皆叹惋。余人各复延至其家，皆出酒食。停数日，辞去。此中人语云：“不足为外人道也。”(间隔 一作：隔绝) 　　既出，得其船，便扶向路，处处志之。及郡下，诣太守，说如此。太守即遣人随其往，寻向所志，遂迷，不复得路。 　　南阳刘子骥，高尚士也，闻之，欣然规往。未果，寻病终。后遂无问津者。 .

Older RHEL 7 kernels try to early load microcode even inside virtual
machine, which may lead to panic on some hypervisors.  In order to circumvent
that, microcode is installed into a kernel-version-specific directory (which
is not scanned by the dracut script, that constructs early microcode binary
in initramfs, by default), and path to microcode files provided only in case
initramfs is generated for the kernel version that properly handles early
microcode inside a virtual machine (i.e. do not attempts yo load it).
The versions of the kernel package that properly handle early microcode load
inside a virtual machine are as follows:
 * RHEL 7.6 onwards: kernel-3.10.0-930 or newer;
 * RHEL 7.5: kernel-3.10.0-862.14.1 or newer;
 * RHEL 7.4: kernel-3.10.0-693.38.1 or newer;
 * RHEL 7.3: kernel-3.10.0-514.57.1 or newer;
 * RHEL 7.2: kernel-3.10.0-327.73.1 or newer.
RHEL 8 kernels are not affected.

If you want to avoid early load of microcode for a specific kernel, please
create "disallow-early-intel" file inside /lib/firmware/<kernel_version>
directory and run dracut -f --kver "<kernel_version>":

    touch /lib/firmware/3.10.0-862.9.1/disallow-early-intel
    dracut -f --kver 3.10.0-862.9.1

If you want to avoid early load of microcode for all kernels, please create
"disallow-early-intel" file inside the "/etc/microcode_ctl/ucode_with_caveats"
directory and run dracut -f --regenerate-all:

    mkdir -p /etc/microcode_ctl/ucode_with_caveats
    touch /etc/microcode_ctl/ucode_with_caveats/disallow-early-intel
    dracut -f --regenerate-all

If you want to enforce early load of microcode for a specific kernel, please
create "force-early-intel" file inside /lib/firmware/<kernel_version> directory
and run dracut -f --kver "<kernel_version>":

    touch /lib/firmware/3.10.0-862.9.1/force-early-intel
    dracut -f --kver 3.10.0-862.9.1

If you want to enforce early load of microcode for all kernels, please create
"force-early-intel" file inside /etc/microcode_ctl/ucode_with_caveats
directory and run dracut -f --kver "<kernel_version>":

    mkdir -p /etc/microcode_ctl/ucode_with_caveats
    touch /etc/microcode_ctl/ucode_with_caveats/force-early-intel
    dracut -f --regenerate-all

In order to override the late load behaviour, the "early" part of file names
should be replaced with "late" (and there is no need to call dracut
in that case).


Please refer to /usr/share/doc/microcode_ctl/README.caveats for additional
information.
