Too little information to answer accurately. What type of virtual machines are you planning on? What will they be doing? Are you running a regular OS on top of the hardware or a bare metal hypervisor?

You'll easily be able to run as many VMs as you can fit on the SSD, which won't be many.

if he does thin provisioning he can definitely fit more than his ram load can handle.

What do you mean what type ?

Are they VMWare or Hyper-V? If VMs are, are they running on workstation or ESXi? Are they going to be on all the time?

Really not enough info but I'd say, run smoothly? Assuming you want them running at the same time smoothly I'd say 5-6 with 2-4GB each. Also assuming you'll be using the host computer for general computing while they are running? If not, I would look at acquiring a Hyper-V server license and going with that. You may also want to give Windows 8 Hyper-V a try.

 

I really can't say how well the i5 will do under the load of 5-6 VMs. If you get more serious about Virtualization especially with lots of I/O you may want to look at non-K processors which support VT-d.

Ok would a i5 handle at least 2 or 3 ok then ? I don't plan on running more than that at one time really. Maybe 4 to the most.

It'll probably handle 5-6 in general, smoothly. Depends on what they're doing and if they're doing it simultaneously. You have enough RAM you should be fine. I would monitor performance while recording, if they all perform acceptably then, you're good.

How do you figure?

Each installation will take about 20GB - this will mean 7 or so installations.

Each installation needs about 2GB of RAM (3GB if you are being generous) - therefore 7 installations could easily be run in 24GB.

 

Like I said - the size of the SSD is more likely to be a limitation.

You're both right. Using bare minimums, you are right. Using real world, Apex is right. The installations can be run in 24GB, but can the applications? Is it a hobby or business? That PVR I/O is going to put that i5 to work.

 

Though I would add the following for the OP to consider:

 

  • If you can use 2GB machines and meet your requirements, I would consider 32-bit OS for the VMs.
  • Assumption is you are NOT recording to the SSD that the VMs will live on.
  • Assuming you have a large secondary physical HD for video storage, I would consider that for y our VM hard disks as well and just put the VMs on the SSD.

My Thoughts

 

  • Going to need Raid
  • Use SSD Drives to host VM's and would recommend RAID again.
  • What about Hyper-V Server (Free)
  • Ask for help on reddit.com/r/homelab
  • Post update please would like to see setup and what happened.

    • AltSendme 0.4.1

      By Copernic · Posted

      AltSendme 0.4.1 by Razvan Serea AltSendme is a minimal, cross-platform application designed for fast, secure, and private peer-to-peer file transfers. It allows users to send files or entire directories directly between devices without relying on cloud servers, accounts, or any personal information. Everything is encrypted end-to-end using modern protocols like QUIC and TLS 1.3, ensuring both strong security and low-latency performance. Transfers are verified with BLAKE3 for data integrity, and interrupted downloads automatically resume, making the experience reliable even on unstable connections. You can transfer anything—images, videos, documents, and more. Integrity checks are performed on both ends, so your files are automatically verified for correctness during both sending and receiving. AltSendme works seamlessly across local networks or long-distance links, capable of saturating multi-gigabit connections for extremely fast delivery. With built-in NAT traversal and encrypted relay fallback, it connects devices almost anywhere. The app integrates with the Sendme CLI and will soon support mobile and web platforms. Fully free and open-source, AltSendme offers a lightweight, privacy-first alternative to traditional cloud-based services, removing size limits, upload costs, and unnecessary data exposure. AltSendme 0.4.1 changelog: Release Highlights Self-hosted relays: Run your own iroh relay so transfers don't rely on public infrastructure. Includes a full deployment template in deploy/relay/ with Docker Compose for a VPS and configuration examples for production use. Fly.io support: One-click deploy template for Fly.io, including a quick-start config (fly.dev.toml) for testing without a custom domain, plus production setup with Let's Encrypt and your own hostname. Relay settings UI: New Settings → Network panel to choose how AltSendme connects: automatic public relays, custom self-hosted URLs (with optional auth token), or disabled. Test connections, verify latency, and see live relay status in the footer. Disable relays: Turn off relay servers entirely when you only need same-network transfers (e.g. LAN). Direct connections only. No relay hop required when devices can reach each other. Android graduates from beta: Android is now part of the regular release cycle alongside desktop. APKs ship with each version (universal, arm64, and armv7). Other improvements Private relay access control via shared auth token Relay fallback notifications when a custom relay is unreachable Broadcast mode toggle in sharing settings Android release build fixes (split-per-ABI APKs, universal APK preservation) UI polish: mobile safe-area insets, dropzone layout, transfer progress animation Bug fixes for minification-related serialization issues and system tray icon loading What's Changed feat(relay): add relay status functionality and settings UI (a120cdf) feat(relay): implement custom relay server configuration and verification (51276c7) feat(relay): add configuration for private relay access and enhance observability features (48fbabf) feat(relay): enhance relay URL validation, display connection status (d4fffa0) feat(relay): add RelayChangeGuard component and enhance relay-related translations (16ba514) feat(broadcast): add toggle setting for broadcast mode in sharing UI (ca6d977) fix(relay): correct QUIC discovery port, pin image, templatize fly.dev (52a2ba5) fix: More broken serialization due to minification (67491a9) fix(android): preserve true universal APK across per-ABI builds (e9f256f) fix(ui): conditional safe-area insets padding on mobile (1182f0e) refactor(transfer): CircularRing component animation fix (944572b) chore(android): drop x86 and x86_64 release APKs, keep universal+arm64+armv7 (34ada0b) Download: AltSendme 0.4.1 | ARM64 | ~9.0 MB (Open Source) Download: AltSendme for MacOS | Android Links: AltSendme Home Page | GitHub | Screenshot Get alerted to all of our Software updates on Twitter at @NeowinSoftware
    • Why Delta Chat is the best decentralized messenger you have probably never tried

      By zikalify · Posted

      You are mostly right about the ephemeral nature of it. As I mention in the article, if you dont add a second device or take a backup of your account before uninstalling it, then yes you will lose access to your account. That said, in terms of actual user experience when you sync multiple devices your message history carries across and there's also a Saved Messages chat like there is on Telegram to send messages and attachments between your installs. But yh, what you point out are correct and its not trying to emulate Messenger or Telegram.
    • You've tried DuckDuckGo and Brave Search, now get serious with SearXNG

      By zikalify · Posted

      OK so SearXNG is a meta search engine that you can install locally or use via a public instance. It scrapes other search engines which you choose and then sorts the results. Not as complicated as multiple relays
    • The Trump administration doesn't want you to use OpenAI's GPT-5.6 without its approval

      By excalpius · Posted

      The only difference here is that you think you came up with these reasons. You didn't. These age old fearmongering lies (that were NEVER true) were funded by and the anger stoked by Putin through proxies like Farage (and later in the USA, Trump) and filtered down through the skinheads, Neonazis, etc. until it reached the uninformed, ignorant, and gullible -- never realizing they were being played for fools against their own best interests. Even now, despite all of the EVIDENCE proving that Brexit was a terrible mistake for ALL citizens of the UK and that its supporters were tricked by Putin's proxies into sabotaging their own nation, you're still here defending these well-known lies as if they were ever true. Not only are they not true. They NEVER were. So, when are you going to realize that you were lied to and actually get angry at the liars and charlatans who lied to you, instead of blaming the innocent people they lied to you about?
