The patching schedule is TOO DAMN HIGH.

Wish I had found this earlier in my auditd journey.

Spent a good amount of time on this.

IPMI is such trash :expressionless:

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

1031

That is IPMIView D:
Well, itā€™s iKVM which was launched by IPMIView.
Iā€™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 doesnā€™t work

edit 3:
actually maybe it worked

edit 4:
itā€™s not complaining about the disk anymore, but itā€™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.

Isnā€™t zvol a native storage backend for bhyve?

Or is it just the libvirt part thatā€™s not connecting the 2?

1035

Bhyve isnā€™t the issue, it doesnā€™t need any special configuration to use zvols. I was just fighting with libvirt.

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

1037

Itā€™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.
Itā€™s already required a few improvements to the bhyve backend for libvirt, which I hope to upstream eventually.

 18520   FreeBSD-13_0-CURRENT-r354057   running

Got that part working now. Again. I had it working already with a slightly different configuration. Now itā€™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?

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

@SgtAwesomesauce have you looked at tlog for recording terminal sessions? I stumbled on it because itā€™s has a cockpit plugin, but it looks like it might be relevant to your session auditing adventures. It has some built-in interface for working with elastic.

The cockpit plugin plays back the terminal session in realtime which is pretty nuts.
