Random question let's say I have 2 PCI Nic cards is there away to assign then to a VM?
Create two macvtap networks with each one using a different NIC. Use one network when creating the VM and add the other network after.

I would have to change the plugin to write the xml (which is possible) instead of using the libvirt domain_disk_add function. I will look at it.

ryecoaaron could you give some guidance please?
I'm setting up linuxserver/netbootxyz docker image and dnsmasq DHCP in proxy mode
I've been following this article
https://wiki.jarylchng.com/boo…-has-locked-dhcp-settings
But I noticed libvirt using dnsmasq in the processes.
Can I add another configuration to dnsmasq without effecting the KVM plugin?
The additional dnsmasq.conf is as follows
port=0
##interface=eth0 ##not used, all 3 nics wanted for netbootxyz
bind-dynamic
log-dhcp
dhcp-authoritative
dhcp-range=192.168.1.0,proxy,255.255.255.0
pxe-service=x86PC, "NETBOOT (BIOS)", "netboot.xyz.kpxe", 192.168.1.253
pxe-service=X86-64_EFI, "NETBOOT (EFI)", "netboot.xyz.efi", 192.168.1.253

That said, if you are going to run dnsmasq in docker, I would consider giving the container its own IP address with macvlan.

If you switch to the kvm plugin, you won't have to worry about all of those virtualbox pains
New openmediavault-kvm pluginI followed you advice to avoid virtualbox pains
sure virtualbox had a nice ui but it was barely working any slight change makes it crash,anyways the kvm plugin is really nice. a bit over simplified but solid
migrated my VMs to it but faced an issue with usb hotplug as just adding the usb device from the plugin works but when its unplugged and plugged back it doesn't work in the VM.
I used a simple windows VM as a print server but the printer is not powered on all the time. so the hot plug was required.
after some tinkering I got it working so here is how it worked.- Create an XML file with the device info for KVM
You can get the product ID and vendor ID from lsusb command
Bus 001 Device 028: ID 03f0:3d17 HP, Inc LaserJet P1005
XML: printer.xml<hostdev mode='subsystem' type='usb' managed='yes'> <source> <vendor id='0x03f0'/> <product id='0x3d17'/> </source> <address type='usb' bus='0' port='1'/> </hostdev>- Get device path from command udevadm monitor and plug or unplug the device to detect it
Mine was "/devices/pci0000:00/0000:00:14.0/usb1/1-3/1-3:1.0"
- Create udev rule file
sudo nano /etc/udev/rules.d/90-libvirt-usb.rules
and add the following
change devpath, VM name and path to xml file to match your setup.Code: 90-libvirt-usb.rulesSUBSYSTEM=="usb", ACTION=="add", DEVPATH=="/devices/pci0000:00/0000:00:14.0/usb1/1-3/1-3:1.0", RUN+="/usr/bin/virsh attach-device Z0-PRINT-01 /mnt/ZFS/NVME/Data/KVM/printer.xml" SUBSYSTEM=="usb", ACTION=="remove", DEVPATH=="/devices/pci0000:00/0000:00:14.0/usb1/1-3/1-3:1.0", RUN+="/usr/bin/virsh detach-device Z0-PRINT-01 /mnt/ZFS/NVME/Data/KVM/printer.xml"Notes:
- For this to work the device must be plugged or unplugged to the same USB port.
- I used the DEVPATH in udev rule instead of vendor id and product id because that method detected only add action not both add and remove action for me.

anyways the kvm plugin is really nice. a bit over simplified but solid
Simple was my goal even though I plan to use it (and I'm a VMware admin all day and have used proxmox for years). If someone needs advanced options, editing xml/using virsh/using virt-manager was the route I think they should take. What did you find too simplified?

after some tinkering I got it working so here is how it worked.I will look at it but parsing udevadm output and maintaining udev rules might be a bit much for the plugin.

Sure simple is better OVM is mainly a NAS OS not a hypervisor, if I wanted to focus on just VMs I'd go with VMware (PS. I'm a VMware admin too
), I haven't tried Proxmox but I'm interested in it.I'm just missing a VM edit page not the devices drop down menu.
something like this -
I haven't tried Proxmox but I'm interested in it.
I actually want to move from Proxmox (at home) to the plugin. I have no problems with proxmox but it is overkill for home needs and running docker directly on the proxmox host is not a good idea.
I'm just missing a VM edit page not the devices drop down menu.
something like thisThe Devices menu in the plugin has the most used devices from the VM edit page to allow similar functionality. Are you missing something from there? virt-manager has it all otherwise.

While I'm not an expert, I wholeheartedly agree. The plugin will be an excellent solution for home and small business use.

Been following this thread with great interest.
But, one question: is the KVM plugin close to being finalized as a stable release (and moved out of the testing repo)? Or is that a while off yet?
-

I wouldn't call it unstable now. I will look at putting in the regular repo but I wouldn't let its location keep you from using it.

Hi, i didnt checked it for some time, the VM, but the noVNC link dissapeard:
the docker container for the VM is running, so I dont know what could happen.. any advice what to check? thx
-
any advice what to check?
If you updated to 5.1.0, it doesn't use docker anymore. So, I would stop the docker manually and start a new console.
-
and start a new console.
sorry for stupid question, but how and where to start the console? using what? so the noVNC column is now useless?
EDIT:
i deleted the noVNC docker container, when i click on create console, nothing happen, it asks to create noVNC on port 8081 and then html 5 on 8091, and those ports are not accessible..., in syslog no errors

orry for stupid question, but how and where to start the console? using what? so the noVNC column is now useless?
No, it is not useless. Instead of running noVNC in a docker, it is now running on the host. Everything from your perspective should be the same.

But something did happen if you were asked for ports. How are you trying to access those ports? Did you click on the links in the grid? What is the output of: ps aux | grep websock
Download Tight VNC -> here .
Then it's server ipaddress:port Example 192.168.1.50:5902
That should still work but skips using the new web consoles for noVNC and spice that I added.
