  papertigers: not sure yet. Maybe Adélie Linux or DragonFly BSD.

  If I run Plex in a branded zone will it have access to the iGPU for transcode?
• 11:54
  sjorge
  wonko: no
• 12:57
  wonko
  Damn. There go my plans to run SmartOS. Thanks!

  you could probably use pci passthru to get it into a bhyve vm
• 14:00
  wonko
  I don't think you can though because it will be attached to smartos. Unless I can get smartos to blacklist it and use a serial console (if I can even get one on that thing).
• 15:30
  bahamat
  wonko: SmartOS has the serial console enabled by default. You can disable it after boot, but there's no way to completely disable it. It will boot up active every time.
• 15:32
  wonko
  Oh, so there's no way to mask it like with vfio on Linux? (Not that iGPUs typically play nice with that anyway)
• 17:25
  papertigers
  wonko: yes, thats what pci passthru is. If you have intel hardware you should be able to pass through something like a graphics card
• 17:25
  papertigers
  however we don't currently have ppt on AMD chipsets

  two examples

  the smartos specific guide might require a bit of tweaking as its a bit dated
• 17:32
  wonko
  This is Intel but it's an iGPU so I'm not sure how well that'll work.
• 17:34
  wonko
  I mean, I guess I can try and see what happens.

  Can I use qcow2 image with bhyve?
• 19:14
  bahamat
  you might be able to run zhyve manually, but if you want an image that you can use for an instance it needs to be a zvol.
• 19:14
  bahamat
  You can use /smartdc/bin/qemu-img to convert qcow2 to raw, then dd that to a zvol.
• 19:16
  Smithx10
  yea, im trying to just get this nvidia netq kvm qcow2 image to load up
• 19:16
  Smithx10
  ALERT! UUID=3756934c-31d3-413c-8df9-5b7c7b1a4451 does not exist. Dropping to a shell!
• 19:16
  Smithx10
  i qemu-img convert'd it to raw
• 19:16
  Smithx10
  but then qemu-image --shrink the raw image to 20gb
• 19:16
  Smithx10
  im wondering if it cut off the backed of the image
• 19:17
  Smithx10
  qemu-img convert to raw made it the virtualsize of the image .... which is 256gb :(
• 19:18
  Smithx10
  Guess i should tar.gz it and scp it over
• 19:18
  Smithx10
  will zfs compress it down or write out the 256gb?
• 19:35
  papertigers
  Smithx10: you might be able to resize the image with qemu-image before the convert
• 19:36
  Smithx10
  while its qcow2?
• 19:36
  papertigers
  I also have had to use qemu-image on linux with some newer qcow2 images
• 19:36
  Smithx10
  did you use linux.die.net/man/1/virt-sparsify ever?
• 19:38
  papertigers
  I have not
• 19:38
  papertigers
  I have mostly converted Ubuntu and FreeBSD cloud images
• 19:43
  Smithx10
  just resize qcow2 down and then convert to raw
• 19:44
  Smithx10
  virt-sparsify has some really cool graphics
• 19:44
  papertigers
  thats what I would try
• 19:44
  Smithx10
  but now im scared
• 19:44
  Smithx10
  Fill free space in /dev/sda1 with zero
• 19:44
  Smithx10
  hope thats the imageon loop rofl
• 20:25
  Smithx10
  Anyway in Bhyve to set a disks UUID ?
• 20:26
  Smithx10
  the UUID of /dev/vda is virtio-BHYVE-6EAB-6BE7-F459 instead of 3756934c-31d3-413c-8df9-5b7c7b1a4451
• 20:30
  bahamat
  That...I don't know.
• 20:30
  Smithx10
  Ill just mount the image see if I can chagen what its looking for
• 23:17
  Smithx10
  papertigers: bahamat figured it out
• 23:17
  Smithx10
  I ended up using virt-resize, but qemu-img resize was blowing up the partition table I think
• 23:18
  Smithx10
  i used parted and resize2fs to shrink down the /dev/sda1 ext4 partition from 255 gb to 20gb, but after doing that and writing out the new partition table
• 23:19
  Smithx10
  I wasn't able to see the partitions after running qemu-img resize --shrink on the qcow2 image
