#libvirt — Public Fediverse posts

My favorite hobby is my #homelab. It’s where I continuously improve my Unix administration and networking skills. It took me basically all weekend but I have my home lab completely isolated and virtualized on an 8th gen i7 Dell OptiPlex 7060 with 32GB of RAM. I also have a 14TB Iron Wolf HD

The hardest part was setting up the virtual network. I’d never done that kind of thing manually. I’d just used whatever default network that #libvirt created for me. This was hard and did require googling and reading #manpages. The problem with the wizard that creates networks is there’s no option for both DNAT and SNAT.

I learned a lot and got it working perfectly despite the garbage #verizon CR1000A router and its notorious bug. Yeah, you can’t add static routes. So I’m in a double NAT situation. Turns out this is okay because it effectively isolates the homelab. All I had to do was add static routing on my laptop and desktop.

Nobody else will be able to access my homelab unless they know its network and gateway addresses, much less how to configure a static route. It’s basic but works.

I think I've worked out what was wrong with my VMs on Fedora 44.

Looks like the firewall rules that Docker sets up do not play well with the ones libvirtd adds.

Forcing Docker to use nftables rather than iptables/firewalld appears to fix things

Anybody else seeing network problems with Boxes/Libvirt VMs on Fedora 44?

I imported an existing disk image and tried to create a new from a Ubuntu ISO and neither get NAT network access.

If so please add any details from here:

I've imported a VM disk image into Fedora 44 boxes (I forgot to export the XML) and while it has got a IP address on the default network it doesn't appear to have access to the outside world (no NAT).

Anybody know how to enable it?

PSA for anyone using #QEMU #KVM for #SingleGPUPassthrough
Guides are all over the net suggesting hooks scripts invoking pci devices, unloading/loading kernel modules, and other unnecessary things. Here's my current hook script for starting the VM:

systemctl stop display-manager

That's it. And the reverse for teardown:

systemctl start display-manager

#IOMMU groups still apply, and you need to pass the correct PCI devices to your VM, but everything else is handled automatically.

Disclaimer that this is how it works currently for my AMD card. I did have a working setup with my NVIDIA card that did unload/load kernel modules, however it seems things have come a long way since I set that up.

Asking the same question here as well.

When using libvirtd/qemu+kvm what is your preferred way for sharing a folder with a huge dataset >50TB into multiple guests especially in the case where you want the VM to be network isolated.

Are you using:
* the filesystem-"device": virtiofs, virtio-9p, mtp
* the disk-device: with dir-source
* link-local network with: NFS, SMB, ...
* a different architecture entirely?

Apparently there is no way to run dhcpd that binds to individual interface and #libvirt network on the same host. The solutions are:

1. Find a dhcpd that binds to *:67 (and then only responds to configured interfaces/networks), or
2. Manage the libvirt bridge network interface manually, or
3. Hack libvirt with a custom patch, or
4. Create a separate interface with different dhcpd port, and bind the dhcpd to that interface and prot. Forward dhcp packets from the desired interface to this custom interface and port.

I found this out the hard way when I planned to replace isc-dhcp-server with kea-dhcp4-server.

Apparently the kernel errors out if different applications want to bind to UDP *:port and UDP interface:port. Multiple apps binding to UDP *:port is fine and that is why isc-dhcp-server works with libvirt.

Two apps binding to different UDP interface0:port and interface1:port are of course ok, but unfortunately libvirt generates the bridge dnsmasq config in a way that doesn't allow specifying the specific interface for binding or excluded interfaces: https://github.com/libvirt/libvirt/blob/3f3cb3ab51740c30f1016c4fe657c48a14cc8462/src/network/bridge_driver.c#L1144

Just discovered libvirt ssh proxy with is working with systemd-ssh-generator to transfer ssh through vsock. So you can simply
$ virt-install --vsock cid.auto=yes --cloud-init user-data...

And then ssh with
$ ssh qemu:system/myvm

no need to predict or discover the IP address (or even to have a network interface)

In my (short) dad time this morning, I've tried to install mgmt [1] to run a distributed hello world on my main machine running on Ubuntu LTS. The built-in binaries depend on augeas which was easy to fix. But also libvirt which is surprisingly old on Ubuntu compared to Debian (latest). I tried to build it myself but I couldn't install nex (the lexer). I then built the binary using Docker thanks to the quick start guide.

I first started to run mgmt in standalone mode. It's nice to see etcd embedded in the binary (at least for testing). Then I tried to deploy multi mgmt nodes with a standalone etcd using docker-compose. I've lost a lot of time trying to override the command because I didn't remember the expected syntax.

I was trying to make etcd listen to all interfaces so mgmt could connect when my daughter showed up.

Finally got my VM hosts updated to the latest AlpineLinux release. Browsing Ceph RBD pools is still broken in `libvirt`… no idea why but one RBD pool works fine, the other refuses to start. (They are configured identically apart from the name of the pool being connected to.)

It tells me "An error occurred, but the cause is unknown". No logs. I asked on `libvirt-users` mailing list: no answer. It's a mystery.

But… if I hand-configure the XML (usually by taking the `dumpxml` output from another VM and hand-editing), I can link to RBD volumes just fine and it just works, so whatever.

The other gotcha was VM types becoming unavailable. A lot of my VMs were `pc-i440fx-3.1` or `pc-q35-3.1` machines. Moving from `pc-q35-3.1` to `pc-q35-10.1` was painless, but going from i440FX-based VMs to Q35 took a bit of hand-massaging the XML: remove PCI IDE/SATA/USB controllers then change the `pci-root` node to `pcie-root`.

Everything is now running `pc-q35-10.1`; so that should kick that can far down the road.

Man the terraform libvirt provider has matured so much. It still seems like a struggle to get bridge networking setup as expected. Something tells that’s strange is even attaching a dom interface to a nat network it won’t pickup an IP.

Creating a domain with `virt-install` seems to work as expected. The domain xml that appears to be relevant is all the same.

Time to dig back into this today.

Some udev rules later and the Palm is syncing again in #debian and #libvirt

Alright, using #talosLinux with #terraform and #libvirt to build out all the #kubernetes infra to run the #selfHosted bits.

So I have 2 5950x with 64gb of ram and 4tb of storage. Then a 3950x with 1tb and 32g, and finally some small older boxes.

My desktop w the 5950 used to be a gaming machine but the steam deck has 100% replaced that functionality.

Eventually I may just run talos natively on either of the larger boxes but libvirt is a much nicer api.

I want to share management of existing #LXC #containers (that I handle with the command line tools) with other people who prefer to use GUIs… (oh, preferences…)

I'd rather not have to "convert" or "migrate" of whatever, but just have the GUI tools manage existing containers without screwing them up…

As I understand, at least #Proxmox will want to create them by itself so it's a no-go.

Anyone experiences with #libvirt / #virtManager can tell me if it's the same or not?

Linux libvirt qemu: Ich war etwas erstaunt, daß die Konfiguration von vCPU = 8 bei einer Windows 11 Gastmaschine zu nur zwei "logischen Prozessoren" führt. Nach der Änderung von "Netzstruktur" auf Sockets = 1, Kerne = 4 und Threads = 2, klappt es dann auch wie erwartet (und gemäß Doku prognostiziert 😉 aber wer liest schon vorher Doku). Jedenfalls ist diese virtuelle Maschine nun auch wieder schnell.

Just learned that you can pass the pci bus address and slot parameters to the #network paramters of #virt-install and thus get stable enp network device names in the VM for use with e.g. #ubuntu #autoinstall.yaml files.

For example:
--network network="testnet",model=virtio,address.type=pci,address.bus=0x02,address.slot=0x00
will be enp2s0 in the VM.

Neat.
