Edit: still annoying but doesn't Hyper-V have startup priority? No it hasnt until I checked 6 months ago. Only way is build a delay schema by hand and assign delays to VM batch start them in layers Hyper-V had startup priority since 2012... fully configurable... startup action and startup delay. This is inaccurate. There is not a priority. Hyper has only ever had this. Okay, technically incorrect.... I'll give you that. The point I was trying to make, was you can artificially set priority VM booting by adjusting the "startup delay" for each VM.

I’ve only tested it with backing up nextcloud user data and it’s been working great so far. What are you backing up to? I only tried an external hard drive and sftp to a Linux Server. I would like to try Backblaze. I would like to check out Wasabi. At first glance, https://wasabi.com/pricing/ looks like it could be a little cheaper than B2. Would definitely be cheaper if you need to download significant amounts often. That was its selling point - a bit cheaper than even B2, but with full S3 compatibility.

Interesting read. I hope I never need to use it. Though, I would rather have it and not need it...

@phlipelder said in Hyper-V Server 2016 guest licensing question: The guests on an OEM licensed host can be moved to another host whether it's licensed OEM, VL, or Retail so long as the destination host is licensed to receive those guests. That makes no sense. That's not moving it, that's buying it twice. Very different things. That's like "can I move my house from here to there"? People mean take the same house and shift its location. Not buy a second house in the new location and give up the old one.

@oksana I doubt you will find the audience you are looking for at reddit, but good luck.

Go figure...CentOS-7 UEFI vm on Windows Server 2019 "Preview" w Hyper-V installs no problem!!!

@vhinzsanchez Containers are lighter and faster. And they are a type of virtual machine, Type-C virtualization. So things like performance and density alone are reasons that containers are popular.

You can restart the Hyper-V Virtual Machine Management service or the Windows Remote Management service and it should work.

@scottalanmiller said in KVM & Networking: I have currently maybe 65 VMs on my KVM host, they each have their own IPs and are bridged. But there is a firewall and NAT sitting in front of all of it. This is really how it is most cases regardless of hypervisor. The only exception is in non-production when dealing with KVM + Wireless NIC... I haven't had time to see if I could get it to bridge somehow, so I'm stuck with NAT on my laptop. But, this is not an issue with servers, as they don't use wireless and this seems to be specific to wireless.

@travisdh1 said in Storage Setup for KVM: @emad-r said in Storage Setup for KVM: @eddiejennings keep your images and ISOs in the default location of /var/lib/libvirt/images/? Yes I do, but I create 2 new folders there, iso and vm. Fedora will be presented a 4 TB block device ? Why dont you separe that a little, and have more fun. Block device I assume DAS, if no why dont you make the storage reliable and robust, and make it its own server, like another fedora or centos install, with RAID 10 and the simplest option to share is NFS, and this way you can have many KVMs and the migration feature will actually work, and you can do RAID on just /var, and you scan scale easily with KVM nodes + KVM nodes can be state file, think salt stack, and you can treat them as pure compute nodes. Because @EddieJennings is talking about his home lab, which will consist of a single 1U server. That hadn't been mentioned in this thread. Bah! Folks should be able to read my mind ;). There were some good ideas in this thread though. What I decided on was giving enough space to / live comfortably, and gave everything else to /var.

@eddiejennings said in Determining resources for hypervisor: @black3dynamite said in Determining resources for hypervisor: Instead of using Fedora as a firewall VM, how about using VyOS? https://wiki.vyos.net/wiki/User_Guide I was thinking of that as well, since the OS for the ERLs. EdgeOS and VyOS are cousins, both descended from Vyatta.

@olivier Thanks for the feedback. Ok... so I see that @julien-f just pushed out new versions of xo-server and xo-web. Anyone care to elaborate on how we could properly script this so that a week from now you could pull the source from this particular point in time?

Hi Kelsey, First of all, as previously mentioned in the thread, the IPOD scenario is absolutely atrocious no matter how you look at it. You pay more to get more hardware to manage to get lower resiliency. Here is a very short paper on why it's particularly important to have HA or FT in a virtual inrastructure: https://www.starwindsoftware.com/fault-tolerance-and-high-availability-page A way to play around IPOD is replicating local storage across the hypervisor hosts. Here is a doc describing how it's done: https://www.starwindsoftware.com/whitepapers/starwind-virtual-san-whitepaper.pdf Also, our forums are pretty helpful and you can ask different virtualization, storage, HA questions there: https://forums.starwindsoftware.com

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

@tim_g said in Hyper-V Network card setup?: @dave247 said in Hyper-V Network card setup?: Thanks. And this isn't for testing. I actually want to use this server for some production servers. Sorry, didn't know. I mistakenly assumed testing and lab because of the time frame. But you can't go wrong with doing it that way. If you have no need for an extra NIC you could do a 3-NIC team. If you are fine with no management NIC, do a 4-port team and share it with your management OS if for some reason you need that many NICs in a team. Though you probably don't. Yeah well it is for some low-risk servers, so, kinda almost testing, but not really, if that makes sense. lol

@black3dynamite said in Centralized Management of KVM Hosts: @scottalanmiller said in Centralized Management of KVM Hosts: @emad-r said in Centralized Management of KVM Hosts: @tim_g said in Centralized Management of KVM Hosts: @travisdh1 said in Centralized Management of KVM Hosts: That looks nightmareish for something that should be quite simple. oVirt is super simple. They have a live boot ISO ready to go to install. I dont think it is super simple at all, if you ask me it is big mess. Only usable in big IT corp. What's difficult about it? In using it, it was just "install and bam, it worked". An SMB would find it far easier than the competition, from what I've used. Isn’t there a script that can be reused at the end of setup, after installing the first time for quicker deployments? That's easily possible, but not something that I've noticed.

@storageninja said in VMware on Azure?: @nerdydad said in VMware on Azure?: Kind of interesting in concept. Charges has to be outrageous though because one would be paying for both Azure and VMware licenses at the same time. Suppose Azure annually would be comparable to physical hardware on-prem throughout its lifetime. Recently I discovered that I can restore a VM from Veeam on a VMware workload to Azure. I thought that was a twist. The issue with doing a restore like that is it's typically a one way trip as... Transit costs OUT of azure suck. You would have to switch to doing agent-based backups to get data out. In the case of this announcement, it's unilateral (With VMware saying they were not consulted). Considering VMware licensing for hosting providers is a special program and Microsoft is not in it this leads to speculation that... Are they trying to get another partner to deploy/manage it? This would likely breach the EULA on the hosting program as it prevented co-marketing/white label stuff like this the last time I read it. Microsoft thinks it can offer vSphere as a service without joining the VMware Cloud Provider Program (This will likely be met with legal). Azure is known to run on custom hardware servers. Unless they've got DL380's or something certified this will not be supported.  Wow, just wow.

@scottalanmiller said in Appropriate Use of Hyper-V Checkpoints: @eddiejennings said in Appropriate Use of Hyper-V Checkpoints: @jaredbusch said in Appropriate Use of Hyper-V Checkpoints: @eddiejennings said in Appropriate Use of Hyper-V Checkpoints: With this upcoming project of virtualizing our production stuff, I've been thinking through the appropriate use of checkpoints. I'm sure there are other articles on this, but this seemed to be a good read. My grand idea is that checkpoints would be used before installing Windows updates or some upgrade to an application. You take the checkpoint, apply the update, and if everything breaks, you apply the checkpoint. If nothing breaks, then you delete the checkpoint. I'm curious how this would be handled with a SQL Server VM or Redis VM. You'd update your VM, transactions start happening, then things break causing you to have to apply the checkpoint. Any transactions that were done would be lost, which upon further thinking probably doesn't matter, since you probably couldn't trust any data put into the database while the stuff was in the process of breaking. You have to make sure you don’t have transactions coming in. Simple as that. Anything is a headache waiting to happen. Makes sense. When I do maintenance on these normally, I stop IIS once downtime’s been announced, then do my work. So I’d just take the checkpoints at that point. I imagine once stuffs back up and I confirm things aren’t broken, Hyper-V just handles merging the avhdx file in such a way that SQL Server, etc is none the wiser. Or is there significant risk of stuff breaking if it’s running while that merge process takes place? No real risk. Just performance loss. And never enought to matter to any SMB workload I have ever had to deal with.
