For Fedora you can just do

sudo dnf install vagrant-libvirt

1 .So can ovirt be run with only 2 nodes?
2. With those 2 nodes, do you need a separate shared storage device for live migrations, etc, or can you have local storage (Like "vsan")?

@FATeknollogee said in oVirt Host Choices for Production:

@EddieJennings I would start by using oVirt Node (it's based on CentOS), it's the simplest, least hassled way of setting up.

Yeah, they have their own Node deployer, I'd generally just use that.

Very Interesting!

@scottalanmiller so cloud is a buzzword?

Oh yes I used to see commercials with a kid talking about the "Almighty Cloud". This was several years ago but not much has changed in the marketing.

It's absolutely used wrong all the time, but that doesn't make cloud a buzz work, cloud is a real specific thing, but almost no one uses it correctly.

@Francesco-Provino said in virt-manager for Windows:

@scottalanmiller you don’t want a GUI on the virtualization host, ever. Just spin a VM with virt-manager and launch it on your local machine with xming or one of the other solutions in the other comments.

Right, bypassing Windows can be an option, but it's a crappy one. But I got it working directly on Windows, so no need for a heavy VM for one app.

@scottalanmiller I was considering rolling them back to last night as a last-ditch scenario is all fails since it is on Veeam and I have a Full from last night.

@Obsolesce said in Conatainers (Docker) vs VMs - When and Why?:

Are there many use cases in the SMB outside of Dev?

Not even in dev really for the SMB. Just use a single VM to do the work. SMB rarely needs to scale.

Other than as you stated, the solution is presented that way. Like UNMS.

Even enterprise rarely need to scale that way. It's more for hosting companies than anything.

@scottalanmiller said in Infrastructure Needed for Hypervisor Cluster:

Clustering is done when the cost of clustering is low versus the risk of not clustering.

I would change that slightly to Clustering is done when the cost of clustering is low versus the cost of not clustering. A risk is always a cost, but some costs are not risks. For example taking down a hypervisor for maintenance vs moving guests to another node and taking down a free node for maintenance.

Sure, using risk cost vs investment cost as cost v cost is a perfect valid way to look at it. I use that all the time in the opposite way.

You can say that risk is a cost. Or conversely, you can look at the clustering cost up front as essentially a "financial event" similar to an outage.

@JaredBusch said in Dashrender why did you migrate to Hyper-V from XenServer:

The XCP-NG team is a team that had a horrible business model that they were trying to implement around XenServer (XOA). Great concept, poor business model.

I wish them well but they are fighting a few things...

Citrix couldn't make any real money even when they charged more and people were taking the product seriously.

Last time I checked they were just replacing some management components and packaging some storage stuff. They are not investing in upstream and there's a lot of... changes coming in hardware that are going to require non-trivial investments for hypervisors to remain relevant.

The real problem with Xen is upstream investment is drying up. Citrix has pulled back, Amazon and other cloud providers have moved on to KVM, SuSE doesn't even market virtualization (SAP HANA support, containers, OS is as close to bare metal as they get). Outside of some people in ARM/automotive virtualization I haven't seen anyone picking it up for net new projects. In the enterprise Oracle is the only champion of it these days. KVM won the open source hypervisor war (although at this point does anyone really care?)

Can you reassign disks between VMs yet?

The hot add disks was a huge pain before. I couldn't believe I wasn't able to do that.

@scottalanmiller said in Kvm network troubleshooting:

Your server has an IP address of 192.168.122.1? Is that correct? Nothing wrong with that technically, but it would be exceptionally unusual. That's almost always the gateway address. What is the address of your gateway?

That's libvirts virtual bridge address for the NAT network.

Oh, duh, I missed the bridge. Carry on. 🙂
