It’s in their guide. The array itself doesn’t write the zeroes anyways so you might as well as allocate it all upfront and avoid any risk of extra latency from allocating on demand. The array itself also thin provisions the actual volume so going thin on thin saves nothing and makes your storage allocation more opaque.

Of course, that's not something that's unique to VMware because there's no such thing as too many tests - even if you have unit tests and integration tests for everything, there are combinations of edge-cases that can only be hit by fuzzing, and even then you not guaranteed 100% coverage.

Holy cow the new vSphere 7 update 3 is bad. I still use esxi 6.7 but upgraded to vsphere 7 because the ui was better, now its worse than 6. All list views paginate at only 35 items and its not possible to shift select a bunch of vms. I suppose its going to force me to script everything like I should because batch operations though the web interface are too tedious now.

I really wanted to put ESXi on my old computer turned Hypervisor, but because there is no support for software RAID and I couldn't get my old Areca card's volume to show up I had to opt for something else and I think i will go with proxmox.

slightly random question for VM goons: what makes Win9x so difficult to emulate? I understand that virtualization companies largely target professional-use OSes and not consumer ones like 95/98/Me, therefore there is little incentive to provide support for it, but it seems to be the one major glaring hole in VM tech. Everything up to 3.1 seems to work great in DOSbox, everything NT4 and up works great in almost everything else. We can emulate 64 core CPUs and hundreds of gigabytes of RAM, but we can't emulate a single-core Pentium and a Rage 128 well enough to not have cursor trails all over the screen in normal use? Too much blue plate special spaghetti code?

Too much blue plate special spaghetti code? As the above already states: Emulation and Virtualization are different. The problem with virtualizing legacy tech is not that it can't be done: It can! The problem is you are basically putting a legacy system onto a modern architecture (i.e. If you install Windows 3.1 inside a Xenserver VM on AMD Opterons, guess what hardware that machine is going to have? That's right. Windows 3.1 running on modern architecture, at modern speeds). Emulation is neccessary because you have both be able to step down the architecture, step down the speeds to something more in line with the hardware the OS was made to live on in the first place. You gotta slow it down, and in the cases of stuff like graphics, you have to emulate older GPUs that look nothing like our modern equivalent. Otherwise, you can run any OS made for x86 hardware on any virtualization platform.

This coincidentally is why I came to this thread. I have a disc-based game from 1997 that I would like to play and I am rather at a loss as to how to do so. I had some success using virtual XP under Win7 and Oracle VM under Win10 Pro, but in both cases the game runs far too fast.

See: https://gaming.stackexchange.com/questions/8420/cpu-or-framerate-limiting-on-older-games Seems like there is some CPU limiter in Virtual Box.

Any KVM/QEMU gurus out there? Running a homelab Server 2012R2 in KVM. How can I give it access to another physical hard drive on the host? I would like to have the 2012 see a physical disk ( say D:) that it can read/write to but would be /dev/sdXX on the Linux host.? Looks like it's not gonna happen directly.

With the added "benefit" that the block device that you're suggesting features even more buffering that keeps the data away from the disks in order to manipulate it, in addition to what Linux does on its own - which risks dataloss.

I have a SAMBA share setup from sdc1 as ext4 fs. All my test Window instances can see that share just fine and are mapped to it. Last time I messed with NFS, I was able to gain root access on a university BSD server in the mid 90s. lol. Was able to mount / on my linux box via dialup. Since I was root locally.... boom done. Good times. I'm still wary of NFS.

Good times. I'm still wary of NFS. More than likely, you either had access the 'nobody' user, since that's historically the user that's been used for that, as the default UID of -2 means that you get errors when trying to mount as root. NFS has changed considerably since then, because NFSv4 no longer sends UIDs/GIDs over the wire and instead uses usernames (well, unless you set vfs.nfsd.enable_stringtouid (or its equivalent on not-FreeBSD), which exists to fix interoperability with NFSv4 implementations that still use UIDs/GIDs over the wire). Also, Rick Macklem, who documented the thing about mapping the uid of root above, is still the maintainer of FreeBSDs NFS implementation to this day.

Yeah NFS has changed significantly, there's still some compatibility issues which keeps SMBv3 king of the roost for file shares, but NFS has significantly improved.

How is the performance of setting up a linux distro as the main system, firing up some sort of virtualbox on that, installing windows 10 on that, and then giving it as much resources as possible, and gaming on the VM? I haven't tried it but I've been thinking about doing it for years.

Its much more common and doable but that doesnt make it easy. The UX is hit or miss depending on your system. You'll either need two GPUs or hope you can get a single GPU working, AMD seems to be more reliable for it. I couldn't get my 2070 super working the way I wanted, for example. You're honestly probably better off just dual booting still, most games run pretty well on Linux these days and for those that don't its 30s to reboot to windows.

This is right up KVM/QEMUs alley. It will turn into a rabbit-hole of forums and learning but its mostly do-able. I purchased a new Ryzen 9 system last year for just this reason. Of course I haven't had any time to try GPU Passthrough out yet..  MAYBE this winter.. Or maybe not.. Got a full plate at the moment.

What's cool out there in hyperconverged these days? I remember people saying that VXRail didn't make them as happy as they hoped but not why. We never did HCI before but we're pondering a new look at it for our on-prem VMware deployment. Nutanix, Cisco Hyperflex, and VXRail are all on my short list right now.

I do not like Nutanix at all. Licensing costs, support, general stuff all not great. If your workload works with HCI, and not all of them do, I liked Cisco Hyperflex at my last job. I wasn't a day to day virt guy, so take my advice with a grain of salt. To be fair our main issue was we were trying to use HCI for workloads that didn't really work with HCI.

Rumor is they're tossing over 20M we spent on Nutanix and hardware and just getting rid of it. The VP driving it left, and there's a new cloud first CIO. There's so much drama and bullshit there now people are really just collecting a check while they figure out what the hell is happening.
