Hey #freebsd #bhyve users!

[mwl@io.mwl.io]

@dexter @ctuffli @Tubsta @dch vm-bhyve, because I'm lazy

[mwl@io.mwl.io]

@Tubsta @dch @dexter @ctuffli

bhyve seems to work well, but yeah, those command lines are

[dexter@bsd.network]

@mwl @Tubsta @dch @ctuffli I am speaking purely from a diagnostics perspective. I believe, to their credit, their log shows the command that was executed. Which is kinda important, given the many “bhyve” bugs along the lines of “it’s treating my boot drive as if it is a CD-ROM drive …” #TrueStory!

So yeah. Share the underlying actual stuff please because very few vm-bhyve bugs are bhyve bugs.

[dexter@bsd.network]

@mwl @Tubsta @dch @ctuffli I mean like, I didn’t write an OpenBSD bug report when I found that typo in Absolute OpenBSD. In of course the one chapter you didn’t trust me to have in advance. Nosiree. THEN you tasked me with raising over $150K to date (USD no less, not that Looney stuff) for a conference.

But yeah sure, blame bhyve.

Until of course it comes time to write a book on the subject… ahem!

[mwl@io.mwl.io]

@dexter @Tubsta @dch @ctuffli

Sure, I ask if something's weird and file a bug.

But sometimes, I'm doing something actively daft. If bhyve-vm hangs trying to launch a host with 75 drives, my first instinct is to say "well, this would be because I'm a damn idiot trying to use 75 drives on one VM..."

[dexter@bsd.network]

@mwl @Tubsta @dch @ctuffli Bruh. bhyve now supports NUMA domains, because test ALL THE THINGS. 75 drives is like… a good start. All scaling issues should be explored to their unholy extremes.

U got this!

[dexter@bsd.network]

@Tubsta @dch @mwl @ctuffli Thar u go.

[mwl@io.mwl.io]

@dexter @Tubsta @dch @ctuffli

okay then, I'll send you my stupid failures.

@mwl
I use 48+ disks zpools on bare-metal hardware, did not see any limit here...

[mwl@io.mwl.io]

Finally getting back to my 72-disk draid bhyve VM for #openzfsmastery.

Turns out that setting ahci_device_limit="8" in the vm-bhyve config let it boot just fine.

Thank you everyone for your suggestions, but especially @dch for this one!
