Hello,
in our inviroment we have VMware ESXi installation through ISCSI boot target image (file) . All inviroment basic on tgtd and dnsmasq service which define boot target file and after installation all changes write to that boot image file. Everything is working ok, but we need to know if that posible to do with Proxmox installation ?
One more, OS is booting from iscsi target file and all changes is writing online.
Thank you.
This is bash script for creating iscsi boot image file ( esxi67u3b20497097-installation-8GB-testing.img ) for VMware ESXi (just like example to better understanding)
