Anyone have an answer here. I'm keen to use the in-built dnsmasq to assist in setting up netboot.xyz on my local network.

Can anyone help out here? I'm still a bit stuck.

Hi
I'm after a working unraid / docker only solution for using serving up Windows/Linux PXE but more specifically ...
I'm running Unraid 6.12.4 and need to set up a PXE environment on my local network to upgrade and maintain a number of laptops and NUC machines. I came across the netboot.xyz project and its corresponding app/docker for Unraid have been installed and seem to be working fine.
I used Serva to test out PXE booting on one of the NUC's and managed to get it to work by running Serva in DHCP proxy mode.
I was running Serva on a Windows VM running on top of my Unraid instance and would rather have a native Unraid DHCP proxy setup instead.
Can someone please advise? I'm also aware of dnsmasq but don't know where to get a version for my version of Uuraid, how to install it or how I should configure it to point to netboot.xyz
Any advice, help or direct solution would be much appreciated .
Thanks for reading

Hi Linguafoeda
> any idea of tips of how to convert an existing Windows 11 install to this new type of template? Again - i'm a bit of a noobie when it comes to this so a bit unsure how to proceed
I'm afraid I dont have much experience in doing something like that. Someone else will need to advise you. Maybe someone from Lime Technology could help us out here?
You might try
Backup your XML for the VM
Create a copy of your vdisk that has Win11 on it
Create the New Windows 11 VM and go through the proper install and make sure its working.
If it's all good shutdown the NEW VM. Edit the new XML and have it point to the copy of your old vdisk instead.
Start the New VM
Cross your fingers
No quarantees on any of that but worth a try. Let us know bnack in here on you get on.

Anyone ? Is there even anyone from Lime Technology in these forums these days I see a lot of unanswered questions. It is so difficult to know where to go with these graphics card pass through problems. I feel like unraid could benefit from a definitive source of truth about what cards work and what configuration is needed to get them to work.
Gripe aside I love unraid and think its fantastic value for money.

Hi
The newest version of unraid has a template that using TPM emulation through the machine type. I would suggest testing a test WIndows11 install to see if that works and then figure out how you might upgrade the install that you have.

Hi
I have a clean install of Unraid (6.12.3) and have managed to get the Quadro FX1800 pass through work to an AlmLinux 9.1 guest VM. However it only works from a cold boot. In other words turn on the machine with the VM on autostart and it works fine. If I stop it though and try to restart it I get garbled video output.
The machine also has a Quadro M5000 card but I'm using that for my tests. I do have them both bound to the vfio at boot in the Tools setting though I must admit it's confusing as to whether this is need nowadays ? Give that it works the first time i'm ignoring this aspect of the problem.
In the logs for the VM I see the qemu startup log is

2023-09-20T01:35:29.116320Z qemu-system-x86_64: terminating on signal 15 from pid 2853 (/usr/sbin/libvirtd) 2023-09-20 01:35:30.537+0000: shutting down, reason=shutdown
I have a few questions that hopefully someone can answer
- The above command using qemu - where is that defined.
- Is it unique to each VM type or just in the template
- When trying to run the above command in the terminal it complained about a missing `Failed to open file “/var/lib/libvirt/qemu/domain-1-AlmaLinux/master-key.aes”` file. Are there other options that I can pass to qemu to help diagnose the problem?
- Is there some tool to dump the important information about the card that I can run before and after its started/stopped so I could compare and see what state it has been left in that results in it not working.
Happy to provide any further information as needed. Thanks for reading.
Cheers

Does anyone have a reply here seems like a lot of these DNS related questions are left unanswered.
