# Summary
Here we provide three CLI tools **vm, ns, netns** that used to auto create KVM Guests, Containers and "net ns" on Linux hosts.
//The prefix **kiss** is taken from the [KISS principle](https://en.wikipedia.org/wiki/KISS_principle)

# FAQ & Examples
## [kiss-vm](https://github.com/tcler/kiss-vm-ns/blob/master/kiss-vm)
**Q:** how to create a CentOS/RockyLinux/Fedora KVM Guest from location(see also: virt-install --location option)?
**A:** vm create $distro \[-n $vmname] \[-L\[=$localtion_url]] #if there's url in default distro.db, just use -L
```
vm create CentOS-9-stream -n centos9s -L=http://mirror.stream.centos.org/9-stream/BaseOS/$(uname -m)/os/
```
**Q:** how to create a Linux KVM Guest from qcow image(see also: virt-install --import option)?
**A:** vm create $distro \[-n $vmname] \[-I\[=$image_url]] #if there's url in default distro.db, just use -I
```
vm create openSUSE-leap-15.3
```
**Q:** how to get the distro list in default distro.db?
**A:** vm create \\ #bash completion will show avalible distro list in distro.db
```
$ vm create #
# CentOS-8-stream RHEL-6% Windows-10 Windows-server-2019 debian-9 fedora-33 openSUSE-leap-15.3

CentOS-8 FreeBSD-14.0 Rocky-8 Windows-server-2016 debian-11 fedora-32 openSUSE-leap-15.2
```
**Q:** does [kiss-vm](https://github.com/tcler/kiss-vm-ns/blob/master/kiss-vm) support auto create FreeBSD Guest with sshd enabled?
**A:** yes, it does (by using vncdotool)
```
vm create FreeBSD-13.0 --msize 4096 --dsize 120G
```
**Q:** does [kiss-vm](https://github.com/tcler/kiss-vm-ns/blob/master/kiss-vm) support auto Windows/Windows-server Guest installing?
**A:** yes, it does since [kiss-vm](https://github.com/tcler/kiss-vm-ns/blob/master/kiss-vm) v2.0.0 (by using answer-file-generator.sh), and like Linux/FreeBSD it enable sshd by default on Windows Guest and support ssh login without password
```
vm create Windows-10 -C ~/Downloads/Win10-Evaluation.iso -f
vm create Windows-11 -C ~/Downloads/Win11-Evaluation.iso -f
```
**Q:** does [kiss-vm](https://github.com/tcler/kiss-vm-ns/blob/master/kiss-vm) support auto installing other systems besides linux/freebsd/windows?
**A:** not yet, but it support maually install other systems from iso/localtion/image/pxe ...
```
vm create OI -C ~/Downloads/OI-hipster-gui-20211031.iso
vm create Fedora-35 --pxe [--net=$pxenet] [--diskless]
```
**Q:** How does [kiss-vm](https://github.com/tcler/kiss-vm-ns/blob/master/kiss-vm) realize automatic installation?
**A:** We mainly achieve the goal of automation by implementing [Redhat based kickstart file generator](https://github.com/tcler/kiss-vm-ns/blob/master/utils/ks-generator.sh), [cloud-init generator](https://github.com/tcler/kiss-vm-ns/blob/master/utils/cloud-init-iso-gen.sh), [windows answerfile generator](https://github.com/tcler/kiss-vm-ns/blob/master/utils/answer-file-generator.sh); then in some special scenarios, we use [OCR](https://en.wikipedia.org/wiki/Optical_character_recognition) technology and [VNC CLI client](https://github.com/sibson/vncdotool) to solve the problem.

**Q:** does [kiss-vm](https://github.com/tcler/kiss-vm-ns/blob/master/kiss-vm) support boot from emulated nvme device?
**A:** yes, it does since [kiss-vm](https://github.com/tcler/kiss-vm-ns/blob/master/kiss-vm) v2.3.0, by adding --nvmeboot|--NB option.
BTW: the nvme driver has not been enabled on qemu-kvm in RHEL, it's only enabled on Fedora release.
**Q:** Does [kiss-vm](https://github.com/tcler/kiss-vm-ns/blob/master/kiss-vm) support creating aarch64,s390x Guest on x86_64 host
**A:** Yes, since [kiss-vm](https://github.com/tcler/kiss-vm-ns/blob/master/kiss-vm) v2.1.0. and it requires qemu-system-$arch has been installed on your x86_64 linux Host.
now we only verified by creating s390x,aarch64,ppc64le RHEL-8/RHEL-9/c8s/c9s Guest on x86_64 Fedora-35/Fedora-36 Host.
Update: Verified Guest list:
```
vm create --arch aarch64 CentOS-8-stream
vm create --arch ppc64le CentOS-8-stream
vm create --arch s390x CentOS-9-stream
vm create --arch aarch64 CentOS-9-stream
vm create --arch ppc64le CentOS-9-stream
vm create --arch aarch64 fedora-36
vm create --arch aarch64 openSUSE-leap-15.3
vm create --arch aarch64 debian-12
vm create --arch ppc64 debian-12
vm create --arch aarch64 debian-11
vm create --arch ppc64 debian-11
vm create --arch aarch64 FreeBSD-13.1
```
Update\[2023-06-06] now also support creating x86_64 Guest on aarch64 host(Fedora Linux Asahi Remix/M2)
**Q:** What other functions or usages does [kiss-vm](https://github.com/tcler/kiss-vm-ns/blob/master/kiss-vm) support?
**A:** just run: 'vm help' to get more usage/examples info; and there are some useful scirpts under the [utils](https://github.com/tcler/kiss-vm-ns/tree/master/utils) dir.
**Q:** ssh login to VM Guest fail with "Permission denied (publickey,gssapi-keyex,gssapi-with-mic)", why?
**A:** try add **-o "HostKeyAlgorithms ssh-rsa"** option to ssh command; see also **ssh -Q key**, **ssh -Q help**
