Truenas Scales VM failed to start

olivierlambert

I can't guess the device you are trying to passthrough and how/if it's used by another VM or the dom0.

The fix is to be sure no other VM is using this device (including the dom0). If you added a passthrough device, you know which one you added, and nobody else can guess it

@olivierlambert I know the other vm which are using the passthough. So do you know I can remove the passthough from the others vms

@jag5cof I imagine it's something like:

List the param of your VM with xe vm-param-list uuid=<uuid>
Find the line like other-config:pci=0/0000:04:01.0
Then you can remove with xe vm-param-remove other-config:pci=0/0000:04:01.0 uuid=<uuid>

jag5cof

@AtaxyaNetwork ok and thanks

jag5cof

@AtaxyaNetwork I'm gettin this error when I run this command

Required parameter not found: param-name
xe vm-param-remove other-config:pci=0/0000:03:00.0 uuid=vm#

I add the correct pci id and vm uuid

AtaxyaNetwork

@jag5cof Maybe xe vm-param-remove param-name=other-config param-key=pci=0/0000:03:00.0 uuid=<uuid> ?

jag5cof

@AtaxyaNetwork I got this error when I ran your cmd - Key pci=0/0000:03:00.0 is not in map

I aslo ran xl pci-assignable-list
0000:03:00.0

@jag5cof I just discussed this with @olivierlambert, the right syntax is:
xe vm-param-remove param-name=other-config param-key=pci uuid=<VM UUID>

He will add the procedure to delete PCI passthrough in the docs

olivierlambert

I updated the doc, it's now available: https://docs.xcp-ng.org/compute/#detaching-a-pci-device

jag5cof

@AtaxyaNetwork I appreciate you working with me on this. It is a learn experience.

jag5cof

@olivierlambert I'm still getting this error - Key pci is not in map

olivierlambert

Check if you have the PCI parameter enabled on the VM first:

xe vm-param-list uuid=<VM UUID>

jag5cof

@olivierlambert What line am I'm looking for on the vm after the
cmd is run

olivierlambert

The other-config line Paste it here

jag5cof

@olivierlambert I'm not sure what you ar asking?

olivierlambert

Paste the output of xe vm-param-list uuid=<VM UUID> in here.

jag5cof

@olivierlambert Do you think it would be easier to re-install truenas and not applied passthough

olivierlambert

No. Just paste the result so we can see the content of the other-config field.

jag5cof

@olivierlambert ok, it's is very long.

olivierlambert

You can just paste the line with other-config:
