All Guest Tools images are located on the server in the directory
/usr/share/parallels-server/tools/. In order to update Guest Tools in the Linux VM:
Connect Guest Tools ISO to the virtual machine
~# prlctl set VM_NAME --device-set cdrom0 --connect --enable --image /usr/share/parallels-server/tools/prl-tools-lin.iso
Login to VM via SSH or VA console.
Check if the Guest Tools CD image is mounted:
~# mount | grep iso9660
If this command returns nothing or the output contains
noexecoption, the image should be mounted manually (the first step is required if the image is mounted, the second one is needed if there is no directory
~# umount /dev/cdrom ~# mkdir -p /media/cdrom ~# mount -o exec /dev/cdrom /media/cdrom
/dev/cdromwith actual drive name in VM.)
Start Guest Tools installer:
~# cd /media/cdrom/ ~# ./install
The installer would suggest you either to upgrade or remove Guest Tools, proceed with "Upgrade" option.
