'''VMware Server''' (formalmente '''GSX Server''') è un software server per la virtualizzazione base di [[VMware Inc.]], una dipendenza di [[EMC Corporation]]. VMware rilasciò la versione 1.0 il [[12 luglio]] [[2006]]. La versione Server è la continuazione della linea di prodotti GSX Server. VMware Server può creare, editare ed eseguire macchine virtuali. Usa un [[sistema client/server]], permette l'accesso remoto alle macchine virtuali. Oltre alla possibilità di eseguire macchine virtuali create dagli altri prodotti VMware, può eseguire le macchine virtuali create da [[Microsoft Virtual PC]]. VMware Inc rende disponibile questa versione gratuita nella speranza di un [http://www.vmware.com/news/releases/server_beta.html aggiornamento] a [[VMware ESX Server]].

Riga 35 ⟶ 34:

Attempting to mount an [[Network File System (protocol)|NFS]] share from a NAT'ed instance of VMware Server may [http://www.vmware.com/community/thread.jspa?threadID=47413&tstart=0 result] in a permission-denied error. To fix the problem, switch the VMware instance to use [[Network bridge|bridged]] networking rather than [[network address translation]] (NAT). Bridged networking implies adding another device on a network, while NAT uses the VMware server to assign the instance an IP address, either through DHCP or through a static IP configuration. Another method of dealing with the permission-denied error involves using [[port forwarding]], but this results in more complexity.

VMware Server can swallow CPU [[interrupt]]s, making maintenance of accurate time difficult.<ref name=vmw_timekeeping_wp>{{cite web |title=Timekeeping in VMware Virtual Machines |url=http://www.vmware.com/pdf/vmware_timekeeping.pdf |format=PDF |date=[[2005-08-01]] |accessdate=2007-09-26 |publisher=VMware}}</ref> [[Network Time Protocol]] (NTP) servers should not run under VMware. -->
