      @obsolesce that's annoying. . .

      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 recently come across Restic and looks great:

      Site:
      https://github.com/restic/restic

      Documentation:
      https://restic.readthedocs.io/en/latest/

      I haven't tried it yet, but it's on my list to try on my KVM server using Google's cloud as a test.

      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.

      I'm using Fedora 28 Workstation with KVM running on cinnamon... i just use copy/paste (ctrl+C/V)

      Or do you mean on a KVM-only host? (gui-less)

      I haven't tried drag n drop... no idea why, but I will tomorrow!

      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.

      And actually looking in the existing directories that I was going to use, nothing was there. .

      Why didn't you set this up before you installed Fedora using custom partitioning?

      Now, why aren't you fixing it via Cockpit?

      Because im tired and running around raged.

      Also I feel like the most popular instructions were a blog post, rather than official documentation.

      I'm not even sure they have a dedicated techwriter. This is why it is better to just follow the official RHV docs. You'll have to filter out the Red Hat specific details, like subscription-manager, but you'll definitely have a better experience

      Runs ScreenConnect.

      So does Fedora.

      Always fail when I do it, there is some trick to it. Happen to know what's needed so that it doesn't just put hashes on the screen for forever?

      Uh there’s no difference. If you freeze the system it can’t be used. This is to run on live systems so they remain running the whole time.

      They definitely get a break if you pour coffee on them.

      @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.

      @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.

      @emad-r If you want diskless, look at setting up a PXE server to boot them from the network.

      If you just want minimal drives locally, then go with the small SSD. I've not found a USB stick that has the same sort of write endurance yet, and have had many fail on me when being used for the OS, temp files, and logging.

      Gluster would just be a normal network mount point to the compute nodes, and DRBL is another way to network boot.

      Converged or hyper-converged really doesn't matter, you want the most cost effective hardware to do the job.

      Without knowing more about what you're trying to accomplish, we can't give anything but generic advice, and even that could be completely wrong.
