• Remote Shutdown ESXi servers

  Good day everyone!

  I use ESXi 5.5.0 on Dell and HP servers. I can remote shut down all virtual machines inside servers, but I don't know how to stop remote servers.

  We will explain:

  When the power source is lost. I have only one auto power off server that plugs directly into the inverter. Before its closure, a command script will be executed at the stop other servers on the network (including virtual machines). But the ESXi server that still store virtual machines running. I do not know how to stop remotely (by command, or 3rd software...). I'm worried about my data may be lost if the ESXi servers are not safe stop.

  Another question:

  If I can stop the ESXi server remotely. Do I have to stop a virtual machines before you stop the real server? Or I can use 'virtual machine startup/shutdown' options to auto shut off all the virtual machine inside the ESXi Server?

  I use the paid license 5.5.0 of ESXi and vCenter 5.5.0.

  Thanks in advance!

  If the virtual machines are not safely stop and then start/stop option can be disabled in the host.

  launch the vsphere client session to the ESXi server and verify that the settings are activated.

  Regarding ssh, it is nothing more than a protocol like RDP connection for unix machines

  We have a tool called Putty to establish an ssh session to the ESXi server. Follow the steps in the article, select ssh shell alone is not necessary. Use the method to do, vsphere client it will be easier

• Can't connect after upgrade to ESXi 5

  After upgrading ESX 4.0.0. for ESXI 5, we are not able to connect console to esx server, there are two choices F2 or F12. I have already set up all the parameters F2, as Ip address, host name...

  Could you please tell how to get or connect to the console command root? even I can't use mastic to apply commands.

  Kind regards

  Ahmed

  Hello.  Even if SSH has been activated before the upgrade then reactivated later.

  Select F2 and log in as root.

  In the menu, select Troubleshooting Options

  Select enable the ESXi environment and press ENTER - this allows the shell local ESXi (use Alt - F1 to access)

  Select enable SSH and press ENTER - this allows SSH

  SSH can also be activated from vSphere Client host-> Configuration-> Security Profile

• 1000V - Importance of the ' system vlan "in port-profile

  Hi all

  Can someone help me understand the importance of the command "system vlan" in a profile of port?

  As I understand it, it was used to mark the criticisms of the system VLAN (package, data, etc.) to their config was pushed to vCenter so that they would continue to work the MSM should be down. Is this fair?

  All of the examples I have watch seems to just mark every VLAN (data VM even VLAN) as "system vlan" in their profiles of prot ethernet uplink. Now that is best practice?

  In addition, there is a reason to mark vEthernet with control panel ports vlan?

  See you soon,.

  P

  As you already wear that system vlan is to ensure access to the vlan vsm to go down and then the esxi host is reset. If the system vlan was not enabled host esxi would not be able to talk to the vsm, but this is only the case if the management port using the Cisco VDS and not a VSS or VDS.

  as I mainly use servers with only 2 ports 10 GB I use system VLAN for ESXi management / storage and vMotion and if the vCenter is a virtual machine, then also the vlan that uses. all other VLANS I don't not in the category system VLAN.

  I use also a VSM Layer 3 so no need to worry the VLAN the packet and data.  But I use that I have several farms esxi in a different subnets from the management and the 1000v in a subnet for network management.

  I hope this helps.

• Do we know how the data store is filled

  We do not know how the data store is filled, ran put space, is there a tool or a way to get the report how the data store is filled.

  1. go to the data store--> select storage views--> then apply different filters to see DS space utlization by VMs, instant.

  2. enable ssh esxi host and log in with the username/password of root and orders below

  #cd vmfs/volumes /.

  #du-sh *.

  This will list all the files/dir on this data store and its size in GB.

  3. or you can use DS to take a quick look at what.

  Thank you

• Updated NIC now I can't connect to vSphere

  I have a system with ESXi installed 5.x, I made changes to NICs because for some reason they were only running in half duplex mode for some reason any. The card has been set to Auto and I forced it 100 Full and then I lost the connection to vSphere. I now can not connect to vSphere because it was networking... What can I do now? Im not too experienced with ESXi so Im at a loss.

  TIA

  Hi AmDD,

  Great that you have access KVM! You can do the following to get management on your ESXi rogue server:

  1. Press and then logon with 'Root' and password
  2. Select Troubleshooting Options in the customization of the system screen
  3. Press to enable the ESXi environment so that it displays ESXi Shell is selected in the right pane
  4. Press to the local shell
  5. 'Root' login and password

  At this point, you should have a shell with ~ # on the screen and a cursor blinking on ready for the entry. If this is the case then continue

  1. Run network vswitch standard list esxcli (assumes that you use a standard vSwitch and not a distributed vSwitch)
  2. Note uplink associated with this vSwitch (read the physical network adapters)
     
  3. Run network nic set-n vmnic5 - esxcli has
  4. Repeat for all the vmnic related delinquency vSwitch

  Once you have confirmed you have taken over the management of the perpetrator, then you can store as follows:

  1. Press to return to the DCUI
  2. Follow steps 1-3 in the first section, but make sure that esxi Shell is disabled
  3. Press can again to disconnect from the DCUI
  4. Grab a cold beverage of your choice and sit back to relax

  Note: This is not strictly necessary but does not remove the fingerprints

  Let us know if it works!

• vMotion and new hardware (cluster) translates the decrease in performance

  Platform 1 is core 4 or 6 X 5550 X 5650 @2. 6 GHz (outside any cluster) on ESXi 5.1 r1312873

  Platform 2 is 4 core E5-2637v2 @3. 5 GHz (Cluster with Mode VCA SandyBridge) on ESXi 5.5 r2068190

  After platform vmotion 1-2 (database servers) users reported a degradation in performance.

  Looking at our charts of cactus representing the CPU usage, we see the following. (You can imagine when the vmotion arrived).

  

  Is this normal? Why is this?

  The specific virtual machine I'm showing here is a virtual machine in version 7 with 2 vCPU and 18G RAM using Linux SLES (kernel 2.6.27).

  Note After the full stop and restart, it's ok (tested on other machines affected in the same way)

  -Very well, we have now disabled power management in the new host BIOS...

• ESXi5 supports nested virtualization?

  Hi friends

  I have a requirement to install RHEL6 Guest OS on a host of ESXi5 RHEL6. Is it possible to install or do you need to change something or the ESXi5 does simply not support? I tried to install it like that and it is said that:

  Connection pooling error ' qemu: / / / system': internal error can not find the emulator suitable for x86_64.

  It is possible in VMware workstation. There is an option in the settings of the VM who: Virtualiza Inter VT-x/EPT or AMD-V/IVR

  but I could not find in ESXi5.

  Any suggestion is very grateful.

  Thank you

• Tech support mode

  Hi all

  I'm putting a vhv.allow = true,

  to my best knowledge, it can be done after the mode of tech support

  looking for some videos but tutorials describe to esxi 4.1 mode tech support, different of esxi 5

  so pls help

  How to activate the mode of tech support in esxi 5

  Thank you

  To get the login prompt on the screen of ALT - F1, you must first enable shell access in the DCUI as explained in the article that Dave provided.

  In short:

  • Connect on the DCUI by pressing "F2".
  • Select "Troubleshooting Options.
  • Select 'enable the ESXi environment '.

• Virtual ESXi / nested virtualization and VCA

  Hi all

  We tried to install some new virtual ESXi servers in our dev environment. to help our R & D.

  The problem is that our clusters must be activated EVC - Merom Genesis so that R & D for work stuff.

  I tried to use the following two articles:

  http://www.virtuallyghetto.com/2011/07/how-to-enable-support-for-nested-64bit.html

  http://www.virtuallyghetto.com/2012/02/how-to-configure-nested-ESXi-5-to.html

  After finishing the first link, the ESXi virtual is able to run 64-bit virtual machines. So all is well (although I stumbled upon both problems with this - apparently, you can't physical host the virtual ESX running in a CVS in the first place of accommodation).

  So after the ESXi virtual is able to run machines virtual 64-bit, I continue to the 2nd link and it doesn't work. I do exactly what the guy said there is still the virtual ESXi is not compatible with the EVC cluster and the 64 bit hosted on the virtual ESXi VM cannot run after changes to the CPUID mask.

  Someone knows something similar? Someone has ideas of what I'm doing wrong or can give me some ideas on what to do?

  Thanks in advance,

  Nitzan.

  In my view, the following option:

  CPUID.1.ECX = 00000000000000001010001000011001

  should be

  CPUID.1.ECX = 00000000000000001010001000111001

• Enable IPv6 on ESXi 3.5?

• The benefits of enabling LDAP authentication for ESXi hosts?

  Hello

  We have been and need to justify the advantages and disadvantages of joining ESXi hosts to Active Directory?

  Thanks 4 your help.

  I see a benefit for sure you can assign complete administrative privileges to individual users in a group. If you assume a group of 10 directors of ESX, individual users can connect to the host via LDAP. Will they make changes or crash the system, you will know who did it. You can follow the verification very easily using this method. Otherwise, everyone will connect as root, and we do not know who is to blame when something crashed, etc.

  It's pretty easy to join the ESXi host in AD and I don't see any problem that I respect. It is individual decision whether to implement or not.

• Enabling VCA with VirtualCenter VM

  I'll have some time to x - mas in power on all my virtual machines and need some ideas on my plan to activate CVS on my cluster.

  My environment:

  3 identical hosts - ProLiant DL585 G2

  ESX 3.5u2

  VirtualCenter 2.5u2 running in a virtual machine

  I can't migrate with virtual machines running. I get the "Incompatibility of CPUID" error when I try migrate running virtual machines in the EVC cluster enabled, so I will need to stop all my virtual machines to activate CVS. The following plan would work?

  1. Shutdown all computers, virtual and leave the VC running virtual machine.

  2. Set host1 in maintenance mode.

  3. Move outside the cluster host1.

  4. Exit mode maintenance on host1.

  5. VMotion VM VC on host1.

  6. Select CVS on the cluster containing host2 and host3.

  7. Clone VM VC - leave it turned off the power.

  8. Migrate powered off clone VC to host2.

  9. Shutdown VM VC.

  10. Plug VIC on host2.

  11. Turn it on cloned VM VC.

  12. Connect to VIC to cloned VM VC.

  13. Migrate original host2 VC VM power off.

  14. Cloned VC VM shutdown.

  15. Plug VIC on host2.

  16. Turn on the original VC VM.

  17. Connect to VIC to original VC VM.

  18. Set host1 in maintenance mode.

  19. Move host1 in the cluster.

  20. Exit mode maintenance on host1.

  21. Delete cloned VM VC.

  Hello

  It seems that it will work.  Not sure I would clone the virtual machine however. Here's what I'd do:

  Stop all virtual but VC computers.

  Stop host2 and Host3

  During feeding on the update of the BIOS to host2/host3 allow AMD - V and the NX/XD Bit

  Make a new Cluster.

  Join the host2 to the cluster

  Select CVS on the CLuster

  Join the host3 to the cluster

  Shutdown VC VM on host1

  migrate VM VC to new cluster

  Power on VM VC

  Make sure that everything in the works of cluster

  Power off Host1

  Updated BIOS for host1 to enable AMD - V and the NX/XD Bit

  Join Host1 to new Cluster

  Recreate Pools of resources

  Reorganize the VMs

  VMs boot

  There should be no need to clone the machine virtual of VC.
