+`os_mount` defines the mount method of tbox's root partition.
+It has the following optional values:
- nfs
- cifs
- initramfs
- container
- local
+Usage example:
- submit iperf.yaml testbox=vm-2p8g os_mount=nfs
- submit iperf.yaml testbox=vm-2p8g os_mount=cifs
- submit iperf.yaml testbox=vm-2p8g os_mount=initramfs
- submit iperf.yaml testbox=vm-2p8g os_mount=container
testbox=dc-8g os_mount=container
Thanks, Shenwei
- submit iperf.yaml testbox=vm-2p8g os_mount=local
+# Optional Values +=================
+## Work flow when os_mount=local
+1. user submit job with os_mount: local
- optional kernel cmdline params: # can be added in kernel_append_root field of job.yaml
- keep_last_root: keep the original data of disk what last job generated, don't wipe it
+2. scheduler return the ipxe_str to tbox
- dhcp
- initrd http://$%7Bhttp_server_ip%7D:$%7Bhttp_server_port%7D/os/openeuler/aarch64/20...
