The WordPress.com stats helper monkeys prepared a 2011 annual report for this blog.
Here’s an excerpt:
The concert hall at the Syndey Opera House holds 2,700 people. This blog was viewed about 26,000 times in 2011. If it were a concert at Sydney Opera House, it would take about 10 sold-out performances for that many people to see it.
Future generations of AMD processors will not include 3DNow! CPU instructions. EVC mode is updated accordingly to hide this feature from older generation’s processors. So hosts which have 3DNow! Instructions will not be compatible with future generations AMD processors unless EVC mode is enabled. As future generation AMD processors will not have 3DNOW CPU instructions. So EVC mode must be enabled for vMotion compatibility between 3DNow! And Not 3DNow! CPU instructions. All AMD Opteron generations 3 are no 3DNow. Generations1 and 2 cannot be made vMotion compatible with hosts that have 3DNow! Instructions
AMD Opteron Gen.3 (no 3DNow) cannot be enabled while there are powered ON Virtual Machines in the cluster
Either migrate virtual machines out of the cluster or power off them. Migration only allows you to schedule a more convenient down time for virtual machine.
Configure EVC cluster by editing VMware EVC settings
If you have migrated virtual machines out of the cluster, power them off and cold migrate them back into the cluster.refer point 1
CPU compatibility masks allows per virtual machine customization of CPU features visible to virtual machine
vCenter compares CPU features of Virtual machine with that of CPU features of the destination host to determine whether to allow or disallow migrations. In cases where you have to decide whether to maintain vMotion compatibility or enhanced CPU feature which guest OS might need, VMware provides check-box to configure individual Virtual Machine.You can configure more advance features as well at the bit level.
EVC ensures all hosts in the cluster present same features to all Virtual Machine even if actual CPU’s on the host differs.
EVC masks only those features which affects vMotion compatibility.
EVC can be configured from cluster setting.
Enabling EVC does not prevent a Virtual Machine from using hardware virtualization features available on new processors
EVC cannot prevent application from accessing hidden features in all circumstances.
VMware EVC cannot be supported on ill-behaved application who does not follow CPU vendor recommended guidelines
Power off Virtual Machines of the Hosts which has greater feature set than EVC mode you intend to enable.
e.g.Cluster has two nodes each of Intel Xeon core 2 and Intel Xeon 45nm Core 2 . So in this case you intend to enable Intel Core 2 EVC mode, then Virtual Machine running on Intel Xeon 45nm Core 2 must be powered off or moved out of cluster before enabling EVC
All hosts in the cluster must be either Intel or AMD but not mixed
All hosts in the cluster must have advanced CPU features like Hardware virtualization Intel-VT/AMD-V must be enabled in the BIOS
EVC compatibility checks detects the absence of features which it expects it to be present for a particular CPU.
All CPU’s in the cluster must have supported EVC mode you want to enable
1. Click Submit error report to send the error report. The Submit Error Report window displays details about the specific error. 2. (Optional) Click the printer icon to print the error log report. 3. (Optional) Click the disk icon to save the error log report. The error log report can be saved as an HTML file. If you are working offlline, this allows you to use the HTML file to submit the error report to VMware at a later time. 4. Click Submit.
