Sorry… by KVM, i mean monitor + keyboard in 1 RU. NOT kvm.

Didn’t edit the above post as you’d already liked it… :smiley:

That’s fine. The more options the better. Just looking for some generally solid recos.

The patching schedule is TOO DAMN HIGH.

Wish I had found this earlier in my auditd journey.

IPMI is such trash :expressionless:

Oh yeah, very familiar with that problem. Try IPMIView.

1031

That is IPMIView D:
Well, it’s iKVM which was launched by IPMIView.
I’ve seen IPMIView have the embedded display too but for some reason with this box IPMIView just has a button to launch iKVM. /shrug

Is this a decent place to ask if anyone has the libvirt XML magic to use a zvol as a disk? I can do it using the libvirt storage pool ZFS backend, but I just want to use the raw device because the ZFS storage backend for libvirt is lacking.

I tried this:

                <disk type='block' device='disk'>
                        <source dev='/dev/${voldev}'/>
                        <target dev='vda' bus='virtio'/>
                </disk>

The config validates but at start I get libvirt.libvirtError: unsupported configuration: unsupported disk type

edit: this seems to be working

                <disk type='file' device='disk'>
                        <driver name='bhyve' type='raw'/>
                        <source file='/dev/${voldev}'/>
                        <target dev='vda' bus='virtio'/>
                </disk>

edit 2:
jk still doesn’t work

edit 3:
actually maybe it worked

edit 4:
it’s not complaining about the disk anymore, but it’s not working either

edit 5:

edit 6:
it works. also this works

    <disk type='file' device='disk'>
      <source file='/dev/zvol/zroot/bhyve/12.1-STABLE/r354051/disk0'/>
      <target dev='vda' bus='virtio'/>
    </disk>

I was missing UEFI firmware blobs.

Get to tweak auto scaling for Fargate tommorow.

Isn’t zvol a native storage backend for bhyve?

Or is it just the libvirt part that’s not connecting the 2?

1035

Bhyve isn’t the issue, it doesn’t need any special configuration to use zvols. I was just fighting with libvirt.

Oh that’s weird. Is it new enough to have the html5 option? Those work really well. The older stuff has quirks.

1037

It’s old :confused:

I see. And you want to use libvirt for easy management?

This seems pretty definitive to me. Have you seen anyone say it works?

1039

I want to use libvirt for easy integration with existing software.
It’s already required a few improvements to the bhyve backend for libvirt, which I hope to upstream eventually.

Got that part working now. Again. I had it working already with a slightly different configuration. Now it’s not using libvirt to manage the storage pool, and I have scripted the generation of the VM images from whatever latest FreeBSD snapshots are available.

But once you can use libvirt on FreeBSD, what will people use Linux for?

That’s my next task once I get all this working: adding Linux VM templates. Gotta make sure things work for Linux too
