minfree Defines the amount of free space left in the LVM volume group pve. With more than 128GB storage available the default is 16GB, else hdsize/8 will be used.

This is space to leave behind for snapshots. They suggest 1/8th the size of your hard drive.

@scottalanmiller I have tried to connect via virtualbox before but after the windows and linux setups the screen would just turn black so i resorted to qemu and followed your discussion but now it wont connect on ubuntu

@stacksofplates What the what?

Install Fedora sudo dnf install -y kubernetes `systemctl enable --now podman1

That's all it takes.

Yeah I see you haven't actually done that.

Podman is not Kubernetes. Also when you install Kubernetes you don't get a podman1 service (or any type of podman service). When you install Kubernetes that way you don't get a Kubernetes service. You seemingly have to start the kube-proxy, kube-scheduler, kube-controller-manager, kube-api-server, and the kubelet separately. It installs docker, which is deprecated in k8s now. They have switched to using containerd which is pretty much the standard runtime now.

So I'll stick with my original recommendation.

Yep, this is why I need to mess with this stuff in my home lab. I can't even talk about it intelligently yet!

@Pete-S said in Script for Creating VMs from Template VM in KVM:

Not the exactly the same thing but you might want to look into how to create a VM from scratch.
Meaning a script that will set up a VM with vCPU, memory, storage, network etc and then boot it from iso and have it do an unattended install, create what users you want and install the packages you need.

That's one of the next things I'm looking into.

@EddieJennings Also remember about things like kickstart in RedHat based operating systems. In Fedora/CentOS/RHOS you can use a kickstart file to automatically select all the install time options for the OS. A short time later you've got a fresh server and all the time it took you to setup was running the creation script on your hypervisor.

One of the things I'll need to figure out going the Kickstart route is setting the hostname what I want it to be at the time of installation. Likely not difficult to do, I just have to figure it out. Or perhaps, I can just truly take the approach of just making a clean minimal install, and then later configure to whatever specific thing I'm wanting the VM to do for my lab / testing.

Inside the kickstart file you'll find something like this:

network --hostname=centos8-4.example.com

We use debian as our goto and then it's called a preseed file. The only real thing that can be tricky is to tell the installation what kickstart/preseed file you want to use. You can do it in different ways. If you don't want to rely on dhcp/tftp/pxe etc you can roll your own iso file. I think the kickstart file can also be mounted as a drive that the installation will detect when it starts.

I think the best approach is to make an automated installation with same basic settings and some of those will get changed later in the installation. For example you can use a fixed hostname that is later changed from ansible.

@EddieJennings said in MacVTap Modes:

One option I didn't see in the redhat doc was openvswitch. Don't they support it?

The link I posted was for RHEL 6. I just now saw that RHEL 8's documentation is online. I glanced through it and didn't see that mentioned. I'll read it more closely tomorrow.

https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/configuring_and_managing_virtualization/configuring-virtual-machine-network-connections_configuring-and-managing-virtualization

There's no mention of openvswitch anywhere in that document. I am aware of XenServer and XCP-ng uses it by default. So its possible RHEL just prefers using macvlan/macvtap instead of openvswitch.

EvTouch USB Graphics Tablet is the default when selecting Server 2019 config template.

That's the one.

And the template didn't load properly when we selected it! It kept going back to Alpine!

I asked if they really had customers who would pay that amount. They said hundreds... Ummm ok, not thousands? Really?

@stacksofplates said in Spin VMs quickly with KVM + virt-sysprep:

I usually use virt-builder to build the image, and then I can clone from that. Then you have nice really small images to build from.

Have you ever created your own repo using virt-builder-repository?

No I've always pulled from upstream. I've honestly never looked into that before.

@FATeknollogee said in Hypervisors: revisit your choices!:

One downside to KVM (in virt-manager) is lack of snapshots for UEFI VMs.

yes it is.

@black3dynamite said in Converting VMware VMs to KVM:

I haven't been keeping up with Windows Admin Center for awhile. Was that an option to manage Hyper-V?

It will be, but I'm not sure that it is yet. We've tried and not been able to get it working even internally anywhere, let alone externally. Once they figure out stability and authentication, I assume that it will be great for that. Being that this is 2016, it's going to suck hard. And if there is a Hyper-V issue, WAC would be down which is a problem in a small environment like this.

Mystery solved.

@stacksofplates said in Automated Provisioning - KVM & CM tools:

Terraform will do this and I have an Ansible role to do it also.
As @IRJ mentioned Vagrant will work also. However I feel Terraform is a better fit as you have more control over the specific pieces of your infrastructure.

You would still prefer Terraform over Ansible for this as well?

Yeah. My role can create the VMs, but Terraform had more functionality for that. Ansible overlaps in the infrastructure provisioning space a lot, but it lacks keeping states like Terraform does.

I'd like to learn both. I just started with Ansible a day or two ago. I have been (and still am) using SaltStack.

So this is ridiculous, but we just found out that it is actually 2003 R2, not 2000. So I assume that this will be way better.

Can you create it with virsh? Wondering if it's just a virt-manager issue since they are deprecating it.

Over my dead body. I love virt-manager they kick that out and I will be kicking them out. not everyone wants web gui using resources and being inefficient with VNC protocol and opening another port.

The web gui hardly use enough resources for you to even notice.

I do agree, cause I have split personality but that said I still want virt-manager to be around. It is very mature and snappy.

Deprecated is probably the same as how ifconfig is deprecated it will be around forever.
