Running ProxMox and many VMs.

VMs

Hive - AbtDev1 - Bandit - Positronic - Morosoph - Glam - Matryoshka - Hoard

Usage

Copy media

On melange, you can plug microSSDs into the melange hub, and you can also reach samba shares.

So direct copy from shares to microSSD is possible without 1Gbit network bottleneck.

sudo su -
mount /media
rsync --progress /spiceflow/... /media/...

Turns out that's not much of a bottleneck yet... my best cards were only getting 100MB/s write speed... test more cards maybe! In the meantime, just use Nautilus on cast.

Reading should def be faster though, if you need to copy from microSSD to shares.

Configuration

Start order

Each VM has a "Start/Shutdown order" Option. We want some VMs to start first. To do that, we set them to a specific order number, with a delay, which will slot them to start before the default VMs. You can also specify an up value, allowing for a pause before starting the VMs in the next order. Nice.

We want hive to start first, so NAS drives can be connected on startup of other VMs.

We might want positronic to start before AbtDev1.... But to do that right, we need to set ALL other VMs to order 2, and AbtDev1 to order 3. It's not even really needed though - AbtDev1 won't be connecting to positronic until I go there and run a development build, and by then positronic should be well under way. So I'll go the much-easier route and leave all VMs other than hive to the default.

NOTE that bitpost is on bare metal, and needs positronic, so manage that manually on any restart of melange!

Hive: order=1,up=60
All other VMs: order=Any (the default)

Upgrade

Proxmox uses apt for upgrades.

6.3 > 7.0

I followed this, for the most part.

  • Update all VMS
  • Shut down all VMS
  • Fully update current version's apt packages - this took me from 6.3 to 6.4, a necessary first step.
sudo apt update
sudo apt dist-upgrade
  • Upgrade basic apt sources list from buster to bullseye
sudo sed -i 's/buster\/updates/bullseye-security/g;s/buster/bullseye/g' /etc/apt/sources.list
# instructions discuss pve-enterprise but i needed to change pve-no-subscription instead - but same exact steps, otherwise
# ie, leave this commented out, but might as well set to bullseye
# /etc/apt/sources.list.d/pve-enterprise.list
# and update this to bullseye
# /etc/apt/sources.list.d/pve-no-subscription.list
  • Perform the full upgrade to bullseye / pm 7
sudo apt update
sudo apt dist-upgrade
  • Reboot

Melange VMs come back nicely. The only snag I caught was that bandit samba shares don't mount (it comes up too fast perhaps?). So restart them then restart qbt nox:

mh-setup-samba-shares
sudo service qbittorrent-nox restart

Looking good!

apt dist-upgrade

I did another round of `apt update && apt dist-upgrade` without stopping containers and it went fine (with bandit fixup still needed after reboot, tho).

sudo apt update
sudo apt dist-upgrade
ssh bandit
mh-setup-samba-shares
sudo service qbittorrent-nox restart

Hardware

  • 4 SAS connections on mobo, with a SAS-to-SATA cable; make sure to turn on "SATA mode" for U.2 in BIOS; all passed through to hive
  • 4 SATA ssd connections on mobo; 3 are passed through to hive
  • 1 TB M.2 nvme
/dev/mapper/pve-root / # /dev/nvme0n1p3
/boot/efi /dev/nvme0n1p2

Passthroughs

We pass the LSI PCI-E board (and its 8 ssd drives), the 4 SATA SSD drives, and the 4 U.2 SSD drives to Hive, for storage management.

LSI PCI-E board passthru

TODO (I don't remember)

SSD drives passthru

USB

Plug something into melange and see what it sees:

lsusb
Bus 004 Device 002: ID 05ac:12a8 Apple, Inc. iPhone 5/5C/5S/6/SE

Now we will pass that port through:

proxmox UI > Datacenter > Nodes > VMs > 111 (matcha) > Hardware > Add > USB > it will actually show up in a pick list!

Hell yeah so easy.

macOS

That doesn't work on macOS. Tried setting usb mapping via console, following this:

sudo qm monitor 111
qm> info usbhost
qm> quit
sudo qm set 111 -usb1 host=05ac:12a8

No luck, same result. Reading his remarks on USB forwarding, try resetting machine type:

machine: pc-q35-6.0 (instead of latest, which was 6.2 at time of writing)
remove this from /etc/pve/qemu-server/111.conf: -global ICH9-LPC.acpi-pci-hotplug-with-bridge-support=off

Hmm.. perhaps it is a conflict between Nick's usb keyboard config and my usb port selection... try plugging usb into another port and remapping...

No luck. FFS. Reset to 6.2 and see if we have any luck with hotplug line removed from config... Nope.

Keep trying permutations... nothing from googling indicates taht this shouldn't just FUCKING WORK...

Remove this and re-add the hotplug line, on the off chance it shouldn't be used with q35 v6.2:

-global nec-usb-xhci.msi=off

Nope, that jsut caused a problem with "Springboard", not working on this Mac, or some shit. Re-adding the line...

Well what now? Google more?

Update and reboot proxmox and retry... no luck.

Try changing from blue to light-blue port... the device is mapped so it should be passed through... nope.

Try this guy's approach to mount an EFI Disk

lsusb
  Bus 004 Device 009: ID 05ac:12a8 Apple, Inc. iPhone 5/5C/5S/6/SE
ls -al /dev/bus/usb/004/009
  crw-rw-r-- 1 root root 189, 392 Jul 22 16:10 /dev/bus/usb/004/009
sudo emacs /etc/pve/qemu-server/111.conf
  lxc.cgroup.devices.allow: c 189:* rwm
  lxc.mount.entry: /dev/bus/usb/004 dev/bus/usb/004 none bind,optional,create=dir

Nope.

Try mapping the port instead of device ID, from the Proxmox UI... Nope.

How can i check the apple side for any issues? straight up google for that, macOS not seeing a USB device.

System Information > USB > nada

hrmphhhh. Never got it working. RE-google next month maybe...

Installation

Add samba shares manually

sudo emacs /etc/fstab # and paste samba stanza from another machine
sudo emacs /root/samba_credentials
sudo mkdir /spiceflow && sudo chmod 777 /spiceflow
๐ŸŒ m@melange  [~] mkdir /spiceflow/bitpost
๐ŸŒ m@melange  [~] mkdir /spiceflow/grim
๐ŸŒ m@melange  [~] mkdir /spiceflow/mack
๐ŸŒ m@melange  [~] mkdir /spiceflow/reservoir
๐ŸŒ m@melange  [~] mkdir /spiceflow/sassy
๐ŸŒ m@melange  [~] mkdir /spiceflow/safe

Now you can mount em up and hang em high!
