Recently doing a P2V Server,Win2000 situation compared to other newer version a lot more,Encountered a problem which is specific to Windows 2000 VM,After installing VMware Tools are still unable to find Intel E1000 network card driver,Internet search abroad was also encountered the same problem,Some may Win2000,Some not。

Yesterday, try adding a third VM Host HA,While functioning,But there is a Integrated Lights Out 4 (iL04) (Active)Warning message,Expand will see if the IP is 0.0.0.0 iLo,ILo have set the IP impression,Puzzled how can this warning。

Today, under the VM you want to install Windows Server 2012 When R2,Failed BIOS Lock out of the error message,HP relationship should look like random limited edition,This change would like to catch a lot of the Authorized Version and then enter the random version number to see,But think not,The original authorization have said can be installed in a VM,Should not therefore no solution fishes,Later, the Internet search,Soon found solution,In the VM can only add parameters。

Last night for the first time through the Web, even into the vCenter Server Appliance,After a look at Information,Can be found directly through the Web patch update,They point down。After the update,Screen display needs to reopen,After restarting the vCenter Server Appliance,Will appear”NO NETWORKING DETECTED. PLEASE LOGIN AND RUN THE COMMAND /opt/vmware/share/vami/vami_config_net TO CONFIGURE THE NETWORK”Error message。

Try to put through a physical vCenter Converter Server Virtualization,Has been present in the last step”The object has already been deleted or has not been completely created”Error message,Internet to climb a lot of text,I felt my situation is different,Transfer log can not see what they were,After repeated testing and then the details of,Finally find out the reason makes me a little dumbfounded。

【vSphere HA】
When vSphere HA fault damage must occur ESXi host,In the only other surviving HA Cluster ESXi host,Will be stored in the shared storage resources of the virtual host VM restart。

If the underlying ESXi host failure damage incident did not happen,But within vCenter Server Hosting service stops when the operation itself,So vSphere HA high availability mechanisms are not helpful。 (It can make up by Watchdog)

【Watchdog】(6.0More than just support,Automatically enabled by default)
vCenter Server 6.0 adds "Watchdog" monitoring mechanism,When a fault event occurs while the operation of the service stopped working,When the former occurs twice,Watchdog will attempt to restart the service,If the third time is still unable to restart the service,VM virtual host will be restarted。

【VMware Data Recovery】
VMware Data Recovery (vDR) belong to the Disk-based backup,Is simple and easy to deploy features (because it is also a virtual host),Support Windows VSS (Volume Shadow Copy) backup,Also supports simple deduplication function (Data De-duplication)。

However, this backup tool has the following limitations related functions:

·Backup environment must have the vCenter Server,Can use this backup tool。
·Disk-based belong,Or can not use the File Level Block Level backup。
·Each vDR can only back up 100 virtual host。
·Not work on IPv6 network environment。
·Only supports backup operations Windows operating system (Windows 2000 / XP / Vista / 7、Windows Server 2003/2008) Web Hosting,Does not support other operating systems,Such as Linux、Solaris, etc. Web Hosting。

【VMware Fault Tolerance】
Web Hosting have a short downtime VMware HA mechanism to start if the company can not accept,The VMware FT may be a solution to the problem,But Enable VMware FT There are many prerequisites,For example, the virtual host can not take a snapshot (Snapshot)、Stoarge vMotion feature can not be used、The virtual host can only use one vCPU conditions, etc.。

VMware FT mechanism will be on two different were established Primary and Secondary Host Web Hosting,And the use of information technology to VMkernel Port vLockstep on the ESX / ESXi Host to transfer Primary Secondary virtual host to the virtual host,But the Secondary will not write the actual behavior of I / O。

When ESX / ESXi Host Primary fault damage which the virtual host,The Secondary virtual host will immediately take over the relevant job,Primary and become virtual host,At this time will be on another ESX / ESXi Host,Re-establish a new Secondary virtual host to synchronize data with the Primary Web Hosting

【總結】
·vMotion/DRS:This mechanism for "Project of" downtime for,For example when the ESX / ESXi Host entity server occur memory、Hard drive failure,Or when need be shut down for firmware (Firmware) update and annual maintenance,This work is scheduled good plan can use this technique,Will work on the virtualization platform of Web Hosting,Migrate to other stations ESX / ESXi Host,So that enterprises can maintain physical host in the case of service without interruption。

·HA / FT:This mechanism is suitable for "non-program of" downtime。When ESX / ESXi Host server entity without power system problems when power failure,When the host entity or motherboard damage leads to physical host to malfunctions of these non-human factors of non-fault condition occurs plan,Through this mechanism can automatically migrate to the virtual hosts on other stations ESX / ESXi Host to continue the operation of the boot。

But it is important that,These mechanisms are merely protecting ESX / ESXi Host Level level only,Rather than the virtual host operating system level (OS Level),As well as applications on the operating system level (Application Level)。

VMware HA mechanisms such as the previously mentioned,When ESX / ESXi Host fault damage,Equal to its operations on virtual hosts and it was improper shutdown,Although virtual host can be turned on again on another table Host,But it's possible the virtual host operating system has been shut down because of improper operation caused damage to the system,So even if you have migrated to other units on the Host,Success can not be a smooth start,So the backup job its necessity operating system。

The VMware FT mechanism is to make two virtual hosts operate exactly the same data,Therefore, if the situation when the crash occurred Primary Web Hosting,For example, the Windows operating system crash occurs blue screen (Blue Screen Of Death,BSOD),Because this time will vLockstep synchronization mechanisms,Secondary and makes the virtual machine host system when the situation also occurred。

As for application-level protection mechanisms,Currently, there are many manufacturers develop mechanisms,For example Application HA Symantec with Veritas Cluster technology development,Is to protect the application to run on a virtual host,Such as MSSQL、Exchange、Oracle、SAP, etc.。

【VMware DRS】
The auto-load the host entity , Automatic scheduling virtual location system , That is, when a higher host load station entity , Through DRS can be part of the subsystem through VMotion to move to a lightly loaded host entities。

VMware  昨天機房跳電後,Wherein when a VM using vSphere Client Connection,Appearance”cannot reach some of the management network addresses of other hosts and thus HA may not able to restart VMs if a host failure occur”。
