I am installing Gentoo in a libvirt qemu kvm virtual machine. The minimal install boot media does not include virtio drivers, making the whole bootstrapping process a big pain since I can't use Gentoo to install Gentoo. Reproducible: Always Steps to Reproduce: To reproduce the issue, simply boot a qemu virtual machine with a virtio based hard drive. The boot media does not load the appropriate kernel modules and the hard drive is unavailable. Expected Results: I do know that you can use some other distro that does include the virtio drivers to start the install, but that really is an ugly workaround. Depending on another distro to bootstrap Gentoo isn't really ideal. I should be able to use the Gentoo install media to install Gentoo on the popular virtualisation environments: libvirt, vmware, hyperv, etc. Here is a short lspci of the virtual machine hardware: # lspci 00:00.0 Host bridge: Intel Corporation 440FX - 82441FX PMC [Natoma] (rev 02) 00:01.0 ISA bridge: Intel Corporation 82371SB PIIX3 ISA [Natoma/Triton II] 00:01.1 IDE interface: Intel Corporation 82371SB PIIX3 IDE [Natoma/Triton II] 00:01.3 Bridge: Intel Corporation 82371AB/EB/MB PIIX4 ACPI (rev 03) 00:02.0 VGA compatible controller: Red Hat, Inc.

Quite a lot of virtio drivers are enabled: https://gitweb.gentoo.org/proj/releng.git/tree/releases/kconfig/amd64/installcd-4.14.52.config I am successfully using virtio here, I suspect something may be wrong on your end. # fdisk -l && lspci -k Disk /dev/vda: 20 GiB, 21474836480 bytes, 41943040 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: gpt Disk identifier: 57C07A1D-F76F-443B-A489-AB819AEB403A Device Start End Sectors Size Type /dev/vda1 2048 526335 524288 256M EFI System /dev/vda2 526336 41943006 41416671 19.8G Linux filesystem 00:00.0 Host bridge: Intel Corporation 440FX - 82441FX PMC [Natoma] (rev 02) Subsystem: Red Hat, Inc.

I tested on install-amd64-minimal-20200913T214503Z.iso just now since that's what I have on hand, but any recent amd64 installcd should work fine
I am mistaken, the minimal install ISO does include the virtio drivers. livecd ~ # lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT loop0 7:0 0 375.3M 1 loop /mnt/livecd sr0 11:0 1 413M 0 rom /mnt/cdrom vda 253:0 0 29.8G 0 disk
