Disable Time Sync on resume from sleep/standby?

I'm trying to disable all guest time synchronization. Per the relevant documenation I've added the folowing keys to my .vmx file :

tools.syncTime = "FALSE"

time.synchronize.continue = "FALSE"

time.synchronize.restore = "FALSE"

time.synchronize.resume.disk = "FALSE"

time.synchronize.shrink = "FALSE"

time.synchronize.tools.startup = "FALSE"

Time sync via NTP in the guest OS is also disabled.

Despite these settings the guest clock still gets synched when the host OS wakes up from sleep/standby mode. How can I disable this?

My environment :

Hardware : Dell Latitude E6510

Host OS : Windows 7 x64 Ultimate

VMware : Workstation 7.1.2 build-301548

Guest OS : CentOS 5.4 (w/current VMware Tools installed)

Per the relevant documenation I've added the folowing keys to my .vmx file :

where do you find those outdated instructions ?

since version 6.0.1 you need




tools.syncTime = "false"
time.synchronize.continue ="false"
time.synchronize.restore = "false"
time.synchronize.resume.disk = "false"
time.synchronize.resume.memory = "false"
time.synchronize.shrink = "false"
time.synchronize.tools.startup = "false"

the line you forgot disables sync when a suspended VM is resumed

I added the one missing item to my .VMX file but I'm still having the same problem. After waking the laptop up from sleep/standby, any running guest OS gets its clock synched with the host OS.

My .VMX file now looks like ths :

tools.syncTime = "FALSE"

time.synchronize.continue ="FALSE"

time.synchronize.restore = "FALSE"

time.synchronize.resume.disk = "FALSE"

time.synchronize.resume.memory = "FALSE"

time.synchronize.shrink = "FALSE"

time.synchronize.tools.startup = "FALSE"

Any ideas how to prevent this time sync?

try to suspend the VM first - then let the host sleep or go into standby

thats more reliable
