Issue when using fw_cfg string=

[alebeta]

Hi all,

Proxmox 6.1-5

I'm deploying a Fedora CoreOS VM on Proxmox.

Basically I use the follow syntax

-fw_cfg name="opt/com.coreos/config",file="/directory.ignition.file"

but to improve deployment I want to use the string option -fw_cfg name=foo,string=foo

this is how it looks like when I try to start the vm using string

-fw_cfg name="opt/com.coreos/config",string="{"ignition":{"config":{"replace":{"source":null,"verification":{}}},"security":{"tls":{}},"timeouts":{},"version":"3.0.0"},"passwd":{"users":[{"name":"core","sshAuthorizedKeys":["ssh-rsa AAAAB3NzaC1yc"]}]},"storage":{},"systemd":{}}"

and proxmox error

kvm: -fw_cfg name=opt/com.coreos/config,string={"ignition":{"config":{"replace":{"source":null,"verification":{}}},"security":{"tls":{}},"timeouts":{},"version":"3.0.0"},"passwd":{"users":[{"name":"core","sshAuthorizedKeys":["ssh-rsa AAAAB3NzaC1yc"]}]},"storage":{},"systemd":{}}: Invalid parameter '"verification":{}}}'

TASK ERROR: start failed: QEMU exited with code 1

I checked the json string and everything to be fine, and it seems to be related in how proxmox is parsing the data?

thanks

Did not really looked into it but you probably want to quote the json string with single quotes for the parameter:
-fw_cfg name="opt/com.coreos/config",string='"{"ignition"....'

Hi Thomas

thanks for your reply, the problem is the same after adding the single quotes
