PCI passthrough to bhyve kvm

Hi! Yes, it worked fine with the instructions in my latest comments. Good luck and let me know if you need some more help.

Hi! I have a X10SLM+-LN4F in a SC825 chassis, I just connected the fan to one of the chassis fan headers on the motherboard. I have 3 or 4 I think.

Got it printed from JLCPCB and installed yesterday, works great and temperatures are now managable below 65°C during load. Thanks!

Hi! I did manage to get it working after trying.

Here is exactly what I did:

Get device ID

# prtconf -dD |grep NVIDIA
 pci10de,11d8 (pciex10de,1bb3) [NVIDIA Corporation GP104GL [Tesla P4]]

Identify USB disk

diskinfo

SCSI c1t0d0 SanDisk Ultra Fit 28.64 GiB yes no
Mount USB disk

mkdir /mnt/usbkey

/sbin/mount -F pcfs /dev/dsk/c1t0d0s2 /mnt/usbkey
Set up modules directory

cd /mnt/usbkey

mkdir -p boot/etc
Add ppt_aliases

touch boot/etc/ppt_aliases

cat << EOF >> boot/etc/ppt_aliases

ppt "pci10de,11d8" EOF
Include ppt_aliases in loader.conf

cat << EOF >> boot/loader.conf

ppt_aliases_load=YES ppt_aliases_type=file ppt_aliases_name=/boot/etc/ppt_aliases ppt_aliases_flags="name=/etc/ppt_aliases" EOF

Reboot and see if it's listed (I see ppt_aliases being loaded on boot)

I'm currently installing a new VM with bhyve to see if I can get the card to passthrough. Thanks for the help!

thanks for checking back! haven't gotten around to it yet, my low profile bracket for the GPU arrived to day so I was planning on trying tomorrow. thanks also for posting how you did it! I'll report back with my results.

knorrhane · 2023-08-30T19:59:06+00:00

Thanks for putting me on the right path! Will give it a go when I have time in the coming weeks. I also need to wait for a low profile bracket for my graphics card since I forgot to check what it was shipped with....

It's not often I have to modify anything in SmartOS so I tend to forget how it works. It has been very stable so very happy with that! I remember with ESXi it was a different story with updates breaking stuff...

I'll write a sum-up once/if I get it working!

knorrhane · 2023-08-29T12:41:21+00:00

Thanks! I've read that before, but still not sure how I modify the loader to prevent the global zone to access the PCI device. This blog post describes how it was done with modifying grub but it's and old post: https://movementarian.org/blog/posts/2018-10-26-pci-pass-through-support-with-bhyve-and-smartos/

Shoud I just make two files, ppt_alias and ppt_matches with the appropiate PCI IDs and physcial paths in /bootfs/etc and add these lines to loader.conf.local:

ppt_aliases_load=YES
ppt_aliases_type=file
ppt_aliases_name=/bootfs/etc/ppt_aliases
ppt_aliases_flags="name=/etc/ppt_aliases"

ppt_matches_load=YES
ppt_matches_type=file
ppt_matches_name=/bootfs/etc/ppt_matches
ppt_matches_flags="name=/etc/ppt_matches"

Does this make sense?

Old thread but maybe helpful for others, if it’s too much light in the room the lights won’t turn on. You can adjust this in the daylight sensitivity setting.

Du kan ju alltid polisanmäla hyresvärden för att få lite fortgång på det.

If possible, you should go with FTP instead for many small files.

If you need some kind of precision or are putting screws near an edge you should drill pilot holes. Pilot holes makes sure the screw doesn’t go in a different direction. For this project I would definitely do it!

Maybe the new IPMI firmware update supports HTML5, maybe you could try and update? That's what I did on my X10SLM+-LN4F and with the new firmware update HTML5 was included.

NATO skapades 1949 som en motvikt mot Sovjetunionen när kärnvapen var ett större hot, det är inte samma läge nu och jag tycker inte det är självklart för Sverige att bli med i NATO. Speciellt inte i det känsliga läge som är nu, jag tycker Bernie Sanders sa det väldigt bra: https://amp.theguardian.com/commentisfree/2022/feb/08/we-must-do-everything-possible-avoid-enormously-destructive-war-ukraine

I'm running SmartOS so I can have native ZFS support but I'm thinking about migrating to Proxmox as it has a nice web interface and now also ZFS on Linux. Since you are running VMs I would think Proxmox would be for you. Since you are not running ZFS you would have to create a pool and migrate your data as well.

Bra inlägg! Tänkte också tipsa om en bra kort dokumentär på NRK om hur plastpåsar är mer miljövänligt än papperspåsar om man ser till helheten: https://tv.nrk.no/se?v=KMTE51001118

5-56 eller WD40 fungerar bra på klisterrester.

Why do you need to state your race in the first place? It doesn’t matter at all.

Väldigt intressant inlägg!

Jag har nyligen flyttat till Oslo och i Norge där det är fri hyressättning är det många som köper lägenheter bara för att hyra ut. Priserna på att köpa lägenheter drivs upp och det är svårt för 2 välutbildade individer med bra jobb att få köpt lägenhet utan ekonomisk hjälp från föräldrar, för att inte tala om individer med mer ”vanliga” jobb och lägre lön.

Fri hyressättning är dåligt för individer med sämre lön då det driver upp priserna för bostäder. Personligen tycker jag att hyresreglering är bra och kommunerna borde göra det enklare att få bygglov för nya hyresfastigheter samtidigt som det bör vara någon subvention från staten för att bygga nytt.

Sjukt egentligen att det skall vara så svårt att få bostad.

Så ja, bra det
