@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.

@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?)

@stacksofplates said in Kvm network troubleshooting:

@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. 🙂

@Dashrender think of this as XOCE to XenServer/XCP-ng but with a desktop instead of a web interface.

Literally nothing different and is completely normal.

So following on from the Other thread.

Looks like i'm heading to the Install KVM, setup a Linux VM and use that to manage the KVM server from that.

@FATeknollogee the install itself has been covered too many times to mention 🙂 Maybe if he runs into a specific issue and solves it, that would be a good thing to share

Conversely, I over-allocated vCPUs across several VMs (ESXi) when I was new to type 1 hypervisors and ran into performance issues associated with high CPU ready times. After scaling down, performance improved dramatically.

@Dashrender said in Why I Feel KVM Is the Easiest HyperVisor to Learn the Basics On:

The question is - why is the quality so bad? Isn't the process supposed to catch bad quality?

Their process is consider the windows insider group (extreme power users) to be a good enough replacement for proper QE teams, and writing automated build tests.

Right, the new process isn't to catch bad things, it's actually to see bad things as "not all that bad." Presumably because a shift from viewing their products as being for business to being for entertainment. Remember when Windows 95 was a key tool for businesses, but by Windows 98 they had made sure to put a "for entertainment purposes only" label on the product to make sure no one confused it with something that was intended for business use?

I feel like that's where they are now. At least internally, no one is really thinking of this as a business tool.

@DustinB3403 said in With ESXi Licensing what happens if I let it lapse:

Microsoft started pulling Security patches off of their servers after your contract expires but the platform is still supported.

Microsoft no longer provides patches for XP Server 2003 unless you pay them a lot of extra money. It's basically a license with security updates for a fixed interval that can be extended for a ton of money...

@scottalanmiller said in KVM with Cockpit on Fedora 29 Network Type Options Greyed Out:

When building a new VM using Cockpit's web interface to KVM on Fedora 29, the Network Type option leaves most options like Bridge to LAN, Generic ethernet connections, and Direct attachment greyed out. Anyone know why?

Did you try with network manager? Any missing package?

@obsolesce said in Fedora 28 KVM Cockpit Doesn't Show All VMs:

Everyone is always waiting for someone else to report bugs and issues, that's why they take so long to get fixed. Not as bad with FOSS, but a big reason with MS for example.

But I don't know that it is a bug. It's reasonable that it might be, but it's just one possibility.

@wrcombs I do! If you don't want to build it yourself, check out Dan's stuff at https://www.techandme.se/

Specifically: https://shop.hanssonit.se/product/nextcloud-vm-microsoft-hyper-v/

I started with one of his builds, then as I became more familiar and comfortable, I started building them myself on Hyper-V. Now I have a couple on AWS LightSail. I don't use Nextcloud for too much, it's mostly for my pics, notes, and bookmarks.

@scottalanmiller said in Delete All Snapshots on KVM with Virsh:

Is this a personal alias to Remove-VMSnapshot perhaps?

No I had that first but edited it incorrectly. Missed the VM in front.

But ya I thought vmcheckpoint was an alias but it's not.

Remove-VMSnapshot is correct.

So weird, they renamed it to checkpoint, but never changed the PS commands.

@emad-r said in Nested hypervisors?:

also as vendor they dont want the complexity advantages of Virtualization

ftfy

Good stuff. Thanks for pointing this up and writing it up.

@jaredbusch said in KVM under fedora workstation - improve performance:

I have zero issues using virt manager viewr for my local guest VM

for remote, I would use RDP or ScreenConnect.

Nothing wrong with it when needed, but it doesn't need to perform well for its role.

At least you get 5 VMs, but the 5Nines gives you 6..

I'll bring it back around and say that now that I've gotten past the couple of annoying obstacles with Hyper-V and remote management, Hyper-V is freaking awesome. It seems lightning fast.

The annoying thing for me is the versioning needed to manage hyper-v. Example: For Hyper-V 2016 you need a windows 10 machine to manage it.

No you don't.

You can pay for stuff to manage it, but I mean it doesn't automatically allow that

Windows 7+ with RSAT.

I just did that at my last job and it didn't allow it

I used Hyper-V 2016 with Win7 RSAT before I loaded Win10.

Hm. I should try it again I guess at home

@penguinwrangler said in 5Nine Free Version:

I like 5nine when you are setting up a new environment and you don't have a domain setup yet. You don't have to go through the rigamaroll of setting up the hyper-v server and your machine to talk to each other. You use 5nine and get your Domain setup in a virtual machine and then join the Hyper-v and your machine to it.

Yeah, it is definitely good to get you going.
