VMotion CPU Compatibility, PERF_MSR Extended-Feature Bit, and Intel Dempsey (and subsequent) Processors (4893083)
Dempsey (and subsequent) Intel processors have bit 15 (PERF_MSR) set in their extended features. For VMotion to occur between Dempsey (or other servers based on Intel Pentium 4 family 15, model 6, such as Pressler, Cedar Mill, and Tulsa), or between servers with older Xeon processors, VirtualCenter Server must ignore bit 15.
Run the following command:
The command returns the following information for a Dempsey processor:
family = 15
model = 6
extFeat = 0x0000e43d
Locate the VirtualCenter configuration file, config.ini (usually located at C:\Documents and Settings\All Users\Application Data\VMware\VMware VirtualCenter).
If the config.ini file does not exist, create a text file and save it with that name.
Add the following line to the file:
migrate.ignore.extfeature.bits = 0xE5A0
Restart the VirtualCenter management server.
