Betriebssystem: VMware Server 1.x
Hotfixe:n/a
Gastsystem:n/a
Problembeschreibung:
Gastsystem läuft recht langsam.
Lösung:
Folgende Einstellungen in der VMX-Datei vornehmen:
| Zitat: |
| mainMem.partialLazyRestore = „false“ mainMem.partialLazySave = „false“ mainMem.useNamedFile = „false“ MemAllowAutoScaleDown = „false“ MemTrimRate = „30“ (kann auch 0 sein, wenn der Gast dann noch funktioniert!!!) sched.mem.pshare.enable = „false“ |
Hier die Beschreibungen zu den Parametern:
mainMem.partialLazyRestore
restore snapshots in background
mainMem.partialLazySave
take snapshots in background
mainMem.useNamedFile
doesn’t use named-file – use for VMs on USB-disks or other slow disks
Windows: useNamedFile= „FALSE“ causes memory to be backed by the host’s swap space.
Linux: useNamedFile= „FALSE“ causes a hidden file to be created in a temporary directory, which is immediately deleted when you power off the VM
MemAllowAutoScaleDown
Erlaubt der VM den Speicher des Gastsystems anzupassen, falls nicht genügend zur Verfügung steht.
MemTrimRate
Workstation checks which part of the guest OS virtual memory is not used and allocates it back to the host OS. This permits to have more concurrent virtual machines running but everytime the guest OS asks back for its memory it suffers a performance degradation.
sched.mem.pshare.enable
VMware uses a page sharing technique to allow guest memory pages with identical contents to be stored as a single copy-on-write page. Page sharing decreases host memory usage, but consumes system resources, potentially including I/O bandwidth.
