Description
Install Junos OS and host software packages on the device.
For installing the host software as well as Junos OS, specify
the package name junos-vmhost-install-x.tgz in the request vmhost software add
command. Junos OS installation alone can be achieved by specifying
the regular package name junos-install-x.tgz in the request system software add
command. However, installation using the vmhost package is recommended
as it upgrades both the host software and Junos OS.
You must load the PTX1000, PTX10008, PTX10016, PTX10002-60C,
and QFX10002-60C devices only with junos-vmhost-install-x.tgz package using the request
vmhost software add
command. The junos-vmhost-install-x.tgz package upgrades both the host
software and Junos OS. The PTX1000, PTX10008, PTX10016, PTX10002-60C,
and QFX10002-60C devices do not support Junos only upgrade. If you
try to load Junos only image, then these devices go down or vmhost
commands do not work or the device state is unpredictable.
Options

Additional Information
Before upgrading the software on the
device, when you have a known stable system, issue the request
vmhost snapshot
command to back up the software. After you have
upgraded the software on the device and are satisfied that the new
package or bundle is successfully installed and running, issue the request vmhost snapshot
command again to back up the new software
to the backup disk.
After you run the request vmhost snapshot
command,
you cannot return to the previous version of the snapshot, because
the previous snapshot is replaced by the new snapshot.
Before installing software on a device that has one or more custom YANG data models added to it, back up and remove the configuration data corresponding to the custom YANG data models from the active configuration. For more information see Managing YANG Packages and Configurations During a Software Upgrade or Downgrade.
