wondering how to do the following
centos as host os on rpi3
gentoo as guest on rpi3
virt-manager comes with centos
but how to get gentoo run inside virt-manager as a qcow2 image?
any installer or steps to do so?
 
Split from Bootable 64-bit RPi3 Gentoo image (OpenRC/Xfce/VC4) UPDATED as its its own specialised question.

honeymak,
Looks like Sakaki has just done it. See the sticky.

i know sakaki's image
but that's rootfs
do i just mkfs.ext4 /normal_file.img
and then extract the tarball to that normal_file.img
and then convert the raw to qcow2?

Yes, just install it the regular way and then convert with qemu-img. If you really need qcow I mean.
The system inside VM doesn't care. |

honeymak,
Make a note of the start of the root partition in fdisk.
Delete the partition table entry using fdisk. This leaves your filesystem intact.
Make a new partition table entry with an *identical* start point, so it points to your filesystem.
Make the partition bigger though.
Now you have a filesystem that does not fill the partition it lives on.
will fix that. That's an online resize.
You can only 'grow' a partition like this into unallocated space as you must allocate contiguous space to a partition.
