When you install a virtual machine, the system uses a slightly different configuration than the normal running configuration (e.g. the installation ISO may be mounted, or PXE boot may be configured). Once installation finishes, the installer is expected to reboot, and instead of rebooting, virt-install shuts down the VM. This is so that it can be ...

you could try looking at the host Get-VM -VMMServer hyper-vhost1

One noticeable difference is paravirtual doesn't support GPU Instances. I'd have created it as hvm had I known that I would want to relaunch it as a GPU instance. edit: Hmm, actually, it seems like we can change from paravirtual to hvm while create an AMI.

are there any disadvantages to allocating RAM in quantities that are not powers of two, or multiples thereof? First of all. Remember that every integer is a multiple of a power of two. So the real question to be asking is if you should restrict yourself to certain multipliers or certain powers of two. Physical machines usually come with memory which is ...

Use something that lets you change the allocations later. ext4+lvm, btrfs or zfs.

Other directories should not grow to significant extent. What you show seems reasonable.

There's no downside. You can add what you need in terms of RAM. Same for CPUs. If you need 3 vCPU or 4 or 5, you can assign as required. Some admins like to see multiples of 512 and 1024, but it really doesn't matter.

No, there are no advantages / disadvantage. Sysadmins tends to prefer the round size, I do. I can build a very small linux system and give it 403 MB of ram, the system will allocate what it is needed for it to work. But, you will not find modules of ram of 403 MB, because everything works with the powers of 2. So simply round to what best fit your build. I ...

If you are fencing hosts with for example impi and one node gets shot in the head with your backup DB running then it's very possible that you will corrupt the database unless it's on a fault tolerant partition that the other host can pick up- can't you use something like galera across the corosync cluster? ...

If you compile it from source? Damn near any version that you can load the required libs for. Sidenote: I found Proxmox to be more flexible than docker.

Perhaps there was a time early on in the development of VT-x when it would reduce performance by a single percentage or two but those times are long gone and I wouldn't expect to see any impact whatsoever now. Obviously if you're using any form of virtualisation disabling it will have enormous negative impact but I'm assuming you know that. The reason it's ...

Umm... no. The original VHD(X) is put into a READ only state and all new writes are written to the snapshot disk. By using the original VHD(X) to get the VM going again you essentially reverted the data back to the point it was in before the first snapshot was taken. You should probably bone up on your snapshot knowledge. Additionally, why are you creating ...

Enabling Intel VT makes CPU hotter, I've had a Desktop and Laptop that have had this behaviour, both with stock CPU coolers. I'm refering to Home Computers but it's the same feature. I know that AMD-V comes enabled by default, but I don't know if it makes CPU hotter.

how any vendor can reliably ensure storage throughput (which is critical for DW performance) without creating a configuration bottleneck? By hiring really smart people to design their back-end systems. Why do we still talk about 'shared nothing' when every single cloud supplier uses virtualization and therefore shared storage? Shared ...

I've heard rumblings that bhyve will be in an upcoming release. But. This really is not something you should consider doing. PFSense is a purpose-built appliance, tuned for routing and network security tasks. Sure, it may be technically possible to do what you propose, but it's a horrible idea. Let your router do what it's good at, and use another ...
