[feature] how to install OS to single disk if multi disks persisted

[guazhangRH]

the KS autopart will use all disks to install OS, but sometime we need some free disks as data disk. so is there a easy method to install OS to single disk.

vm RHEL-8.9.% -n test1 --xdisk 20 --xdisk 20 --xdisk 20 --xdisk 20 --xdisk 20 --xdisk 20 --nointeract

seems some compose named like RHEL-x.y.z-updates-.d. released without guest image. please try:
vm create RHEL-8.9.?-2% -n test1 --xdisk 20 --xdisk 20 --xdisk 20 --xdisk 20 --xdisk 20 --xdisk 20 --nointeract -f

you will get expected result:

 ~]$ vm exec test1 -- lsblk
NAME   MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
sr0     11:0    1  374K  0 rom  
vda    252:0    0   64G  0 disk 
├─vda1 252:1    0    1M  0 part 
├─vda2 252:2    0  100M  0 part /boot/efi
└─vda3 252:3    0 63.9G  0 part /
vdb    252:16   0   20G  0 disk 
vdc    252:32   0   20G  0 disk 
vdd    252:48   0   20G  0 disk 
vde    252:64   0   20G  0 disk 
vdf    252:80   0   20G  0 disk 
vdg    252:96   0   20G  0 disk

just added new option --ks-only-use option to kiss-vm for installing with location:

[jiyin@fs-qe kiss-vm-ns]$ vm create RHEL-7.9  -n testvm --nointeract -L --xdisk 20 --xdisk 20 --ks-only-use=vda -f
.
.
[jiyin@fs-qe kiss-vm-ns]$ vm exec testvm -- lsblk
NAME          MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
