| jayjo_ | I'm trying to test running a pfsense VM on ubuntu as a router/firewall. I'm using netplan. Can I set the first ethernet port as a bridge to only forward to the pfsense VM, and then the second port for pfsense to use as the LAN? | 02:43 |
|---|---|---|
| jayjo_ | This netplan example: https://netplan.io/examples/#configuring-network-bridges looks like it would forward all traffic to a VM. I have four ethernet ports. Can I use the first as a WAN, the second as a LAN for the VM, and the 3rd & 4th for the ubuntu host? | 02:45 |
| sarnold | jayjo_: it's possible the device passthrough described at https://ubuntu.com/server/docs/virtualization-libvirt could also do what you want | 02:47 |
| jayjo_ | I've looked at that article a bit. Do you mean to generally use the xml file to make the edit permanent? I'd like to have the VM running like: https://bpa.st/LXNQ but that requires the network defined prior | 03:20 |
| jayjo_ | Do I just need the VM to have access to both ethernets, and it's really a pfsense question? | 03:23 |
| sarnold | jayjo_: I think that's how I'd approach it first -- give pfsense both nics, and try to stay out of the way otherwise | 03:25 |
| jayjo_ | each of those actual nics would have to have a separate bridge, right? So I can just expand the netplan.io examples by adding a second interface? | 03:31 |
| jayjo_ | My ubuntu host has 4 NICs: enp1s0, enp2s0, enp3s0, and enp4s0 | 03:33 |
| jayjo_ | I would then have two virtual bridges for enp1s0 and enp2s0. The first still gets DHCP from the ISP https://netplan.io/examples/#configuring-network-bridges like using dhcp: true | 03:34 |
| jayjo_ | is the second just a 'plain' bridge? | 03:35 |
| sarnold | jayjo_: I don't understand this terminology, and haven't used pfsense myself. I'm just accustomed to hearing folks using pci passthrough or interface passthrough to give the port to the VM *entirely* and let it do whatever it's going to do; then you use the other two nics on the machine for your host os, other guests, etc, with bridges etc as necessary | 03:41 |
| sarnold | jayjo_: it's time for me to run, have fun :) | 03:41 |
| jayjo_ | thanks for your help! I appreciate it! | 03:45 |
| jayjo_ | Is multipath a way to interact with SAN machines? Or with RAID arrays? Or is it an abstraction for both? (As you can probably tell, I'm not currently using it) | 18:00 |
| stgraber | jayjo_: it's a way to handle any storage device which can be access by more one path | 19:01 |
| stgraber | jayjo_: this is most commonly found with fiber-channel SANs that can have multiple controllers and/or go through multiple switchs, giving your HBA possibly dozens of paths to the drives | 19:02 |
| stgraber | jayjo_: but you can also get that just locally on some server when using a SAS backplane with multiple uplink ports | 19:02 |
| stgraber | jayjo_: and it should also be possible to have multipath for things like iSCSI devices or other ethernet/ip based storage | 19:02 |
| jayjo_ | I have two extra HDDs not being used in my desktop (1TB and 500GB) via SATA connections. Can I use multipath + LVM with them to see it in action? I'm reading through a bit more of the docs.. it seems to be the layer above raid. Would multipath be used to access the RAID 1 array? Or, it could be, but only if there were multiple paths to the array? And in my case connected directly to the bus, there | 19:33 |
| jayjo_ | aren't? | 19:33 |
| jayjo_ | I do see "You cannot group different disks with multipath, only disks that have more than one path/connection." | 19:51 |
| TJ- | jayjo_: that's the point - multipath mean multiple physical paths/lanes/wires/fibres to the target device (somewhat muddied when playing with multipath in virtualised environments) | 19:53 |
| Aison0 | question to initramfs.conf: can I set MODULES to most and netboot? or can I only set one? does most include netboot? | 20:45 |
| tomreyn | Aison0: did you look at the man page, yet? | 20:49 |
| tomreyn | it explains what these settings do. | 20:49 |
| tomreyn | and you can only set one. | 20:50 |
| Aison0 | I would like to use netboot, but also for most hardware ;) | 20:53 |
| Aison0 | I think, the man page is not that helpful | 20:54 |
