Containers or VM guests makes no difference here.

Rarely does.

(I know some Nutanix guys tried it but kept burning out SATA DOMs).

Sata dom? Who the f*** still uses them? Even when I was a c++ coder in automation industry we were phasing out them 3 years ago! Just mainteinance of production stuff.
Btw I see your point. For these applications
MS releases Windows embedded compact only

Hi @stacksofplates. Did you find something about virt module.
Here's https://docs.ansible.com/ansible/latest/modules/virt_module.html#virt-module link.

But, I cannot build a machine? with creating command.
by the way: your article is awesome.

Yeah that's why I wrote this. That virt module doesn't support cloning systems. I never got around to linking that module. I'll see if I can find it again. You just need to put it in your local module library and then you can call it like any other module.

@fateknollogee said in Fedora 26 Cinnamon KVM QEMU VM Guest dual-monitor:

Why not triple monitors at 2560 x 1600...

No need. I only have two 1080p monitors set up. So one at full screen and the other at 1600x900 works perfectly for my needs.

Any open source and free KVM backup software

FOSS is not a requirement to me.

If there was a robust package I could use to get agentless and CBT and file level restore on KVM, I will buy it, if it is reasonable.

There was a thread on the other site about Unitrends having agentless on it sometime this year. Ill have to see if I can find it.

But I cannot even install Unitrends on Hyper-V server.............

Are we allowed to post links from there?

Yes

Since when?

Since the person who made up that insane rule was removed from the site.

Would that insane person be Dave?

Who is Dave?

Nvm.

Oh, Dave from over there? I've never heard him called Dave before. Sorry, I knew it was a joke but couldn't figure out what the joke was.

@dashrender said in Port - How to go about setting up a client to be virtualized?:

As for Sharepoint - You don't get that much storage in Sharepoint in O365, so you'll likely be paying for more storage there. Sharepoint also has a number of files per site limit, just something else to watch out for.

For future reference to anyone wondering, I spoke to three different O365 reps today and they said the limit has been bumped to 1 million items so we'll be good for a while!

That's a bit more!

Solved
I posted this on https://www.redhat.com/archives/virt-tools-list/2017-August/msg00210.html

Laszlo Ersek posted the solution: https://www.redhat.com/archives/virt-tools-list/2017-August/msg00244.html
It can be mitigated manually: when the VM boots, interrupt it at the
TianoCore splash screen. In the setup utility, navigate to:

Boot Maintenance Manager
Boot Options
Add Boot Option

In the file chooser, select

<whatever device you have>/EFI/fedora/shim.efi

and enter a description (name) for the boot option.

Then,

Boot Maintenance Manager
Boot Options
Change Boot Order

and move the new boot option to the top of the list.

After you commit the changes, you can forcibly reset the VM, or else
return to the setup TUI front page, and select Reset there.

@r3dpand4 said in Compuverde: vNAS or Hyperconverged:

@fateknollogee I mean that's depending on your deployment, it's included with 2016 Datacenter....

So is Storage Replica and whole bunch of things you aren't going to use if you aren't within hyperconverged setup. VMware with a separate SKU for VSAN got a better idea. ImHO.

I'm having a hard time following this. So we have one(two) KVM host, fedora instance running virt manger, another fedora running vnc server?

Install Cockpit: dnf install cockpit cockpit-machines
Then do a dnf group install "Virtualization".

Set each VM to use SPICE and VNC. You can get VM console access via Cockpit and the VNC display.

cockpit gets installed on the KVM host?

Yes.

Can I create VMs within cockpit? I do not see an option for that.

No, but you can connect to your KVM host via virt-manager from another Linux PC.

Or do a search for my Kimchi guide:

https://mangolassi.it/topic/14675/fedora-26-kvm-html5-remote-access-with-web-console-via-kimchi

Guide is here:
https://www.timothygruber.com/linux/fedora-26-kvm-html5-remote-access-with-web-console-via-kimchi-part-1/

I have tried connecting virt manger to my KVM host but I get all kinds of errors. Not sure if I am doing it right. Do you have a guide for connecting to a remote KVM host with virt manger for a non-root user? I get lots of accessed denied. I did end up finding your guide after searching cockpit on the forum.

You have to put your user in the virtual manager group. Forget the proper name of the group.

@romo now there's a workaround if I've ever seen one...

So I was playing with Kimchi and I noticed this, I supposed to be running Centos KVM host and not guest.

I researched and I dont want to read 1000 page from RedHat, I wondered anybody have more info about this, and is there CLI command where you can manage this ?

It's probably just an interface for tuned. The names look similar.

Correct, the file is

/etc/tuned/active-profile

And there is service called tuned, thanks for this.

And to check on profiles available:

tuned-adm list

@mlnews

Thread resurrected !!!

I see, interesting . Regarding Ovirt + GLusterFs my update on this is that did learn glustering and it was easy to perform. I didnt apply it in production or VMs. I did use Ovirt a month ago and it was very slow web ui experience.

I should write a thread about my and Gluster.

Libvirt is the one that provides the Backing Store, see below:

@john-nicholson said in Open Source Hypervisors: do we really have them? do we really need them?:

@msff-amman-itofficer said in Open Source Hypervisors: do we really have them? do we really need them?:

my take on this:

ESXi free is limited, 8 vcpu per VM and that limit can be easily reached limit.

It's easily reached if you starve a VM of IOPS or RAM and it's spinning cycles waiting on IO. In reality VERY few things need 8 vCPU. I've seen The ONLY exchange server for 5000 users not need that many resources.

Given modern Skylake hardware, and 4Ghz Intel Xeon Cores's if your hitting the 8vCPU limit I'm REALLY curious why your not willing to spend the one time ~$200 per host that is the Essentials bundle to get some more features is a rounding error in your budget (it's like less than a $1 a day per host).

Keep in mind it is not per hosts, but ~$600 per three hosts, so for much of the SMB that's either $300 or $600 per host and makes things like future upgrades potentially a problem. And $600 per host is enormous for the SMB market. Absolutely staggering. Given that 90% of the market can't even cost justify a server, let alone a server with that much additional licensing.

On a single host, how much value is that $600 getting an SMB versus getting free, unlimited use virtualization with $600 of faster hardware? When we are talking a $3,000 server, an extra $600 is anything but trivial.

The "only $200 per host" is really "holy crap, $200 per host with a minimum of three!!" That's not at all a small number, not in the SMB market. And especially not in an SMB market outside of the US.

@RamblingBiped said in KVM Installation and VM Creation on Fedora 25:

I did an article about a year ago about setting up KVM/QEMU on Ubuntu 16.04, it might be of some use: https://www.ramblingbiped.com/build-a-kvm-qemu-hypervisor-on-ubuntu-16-04-server/

I also wrote a short blurb on automating VM creation using a pre-built VM template, virt-clone, and virt-sysprep: https://www.ramblingbiped.com/build-a-kvm-qemu-hypervisor-on-ubuntu-16-04-server/

That is very helpful. Thank you.

I still love XenServer and XenOrchestra as my one of choice for now. But then i'm only running small Linux/Windows servers on it anyway like Zabbix, Radius, Unifi. Nothing full production like the DC or Dynamics/SQL

Same here, but cautiously watching...

@scottalanmiller said in KVM vs XenServer:

@kuyaz said in KVM vs XenServer:

Can memory be shared also between VM?

That depends on the hypervisor. VMware ESXi can do this. It's an extremely limited feature and of little value. It's neat and good for things like VDI, typically, but not very useful for servers and there is a reason most platforms don't work towards adding it.

I concur. For most workloads, it's more a pain than a solution.

yes I just realize that my question is stupid for the RAM part 😄
