Recompositionisexpeditedthroughtheuseofanadditionalprotectedlinkedclone
desktopinVirtualCenter—calledasourcevirtualmachine—thatiscreatedalongside
thereplicawhenalinkedclonedesktoppoolisfirstdeployed.
Whenarecompositioneventtakesplace,thesourcevirtualmachineisthefirstdesktop
toberecomposedagainst
anewsnapshot.ViewComposerremovestheexistinglinked
clonedesktoppoolfromVirtualCenterandthencopiesthesourcevirtualmachineas
manytimesasnecessaryinordertoreplaceit.
Thismethodofpoolgenerationoptimizestherecompositionprocessandistypically
muchfasterthanindividuallyrecomposingeachlinkedclone
desktopinthepool.
Desktop Refresh
Adesktoprefreshissimilartoadesktoprecompositionbutwithoutanychangetothe
baseimage.Thisactioniscarriedoutinordertorestorethesystemdataforadesktop
pooltoabaselinestateandtherebyreducethesizeoftheoperatingsystemdataofeach
attachedclone.
Adesktoprefreshcanbecarriedouteitherondemand,asatimedevent,orwhenthe
operatingsystemdatareachesaspecifiedsize.Figure 6‐3illustratestheeffectofthis
action—notethattheuserdatadiskremainsunaffectedbythisevent.
