Ping or vmkping in ESXi

• difference between a command ping and vmkping in hosts esxi 4.1

  Hello

  I can't enter the vmkping command and the command ping when it is used in virtualization, esxi hosts, but correct me if I am wrong in my assumption

  1. the vmkernel which is the firmware if you like vsphere suite that manages all communications between the physical host computer and comments, is the hypervisor if you like, correct?

  2. the vmkernel has its own virtual ip stack that manages all vmotion, iscsi and fiber storage correct traffic?

  3 Let's say I have two esxi hosts (esx1 and 2) using two NICs to uplink where vmnic0 on both esxi hosts are virtual machine port groups and the vmnic 1 is used for the port of vmkernel on esi 1 and 2.

  the standard command ping ping ip addresses on both hosts of esxi vmkernel, but she would not use the internal ip stack of vmkernels to check the communication between the two ports uplink vmkernel, instead it uses the co-location host tcp/ip stack to resolve the IP address connectivity and would only check each link port communication.

  by using the vmkping command, it connects esx1 host using putty for example and issues a command vmkping to ESX2 to host esx1, which uses its own tcp/ip stack of vmkernel to achieve a connection from esx2, so indeed the ping moves port vmkernel esx1 directly on the port of uplink of the esx2 and back again check connection of storage correct

  apologies if I didn't explain better, but if you need additional information on my question let me know.

  Thak you.

  Hello

  Yes you are right. The VMkernel is hypervisor - the thing that makes the magic of the work of virtualization.

  The VMkernel has an IP stack to do the things that you have mentioned: vMotion, iSCSI, NFS, etc. which do not exist as on the VMkernel interfaces. Often, but not always, these IP addresses are not accessible outside the VMkernel. For example, if you run an isolated network dedicated to these services. Essentially by issuing a vmkping you issue a ping from the VMkernel interface for another interface, VMkernel not necessarily another interface.

  Compare this with the ping who seems just the Service Console interface.

  If we look at a simple ESX build - two hosts (ESXA and ESXB) with two NICs (vmnic0 and vmnic1). On the ESXA and B, we have the Service Console running vmnic0 with the natachasery connected to a switch. We perform a cross on the cable between the hosts connected to vmnic1 and have configured it for vMotion. In this scenario if you issue a ping from host you a submission in response to the Service Console of IP and other devices on the same subnet connected to the switch. However if you ping the address of vMotion you won't because it is on another inaccessible network - in steps vmkping.

  Trust that this assistance.

• Unable to ping Virtual Machines within ESXi host (vSphere Home Lab)

  I'm using VMware workstation 9, I have 4 virtual machines created inside the workstation.
  (192.168.1.0 network is defined inside VMware workstation VM network editor)

  Domain controller - 192.168.1.1
  ESX1 - 192.168.1.11 (2 NICs - vmnic0 and vmnic1 connected to n/w)
  Esx2 - 192.168.1.12 (2 NICs - vmnic0 and vmnic1 connected to n/w)

  I have 2 virtual computers created inside the machine Esx1

  machine to SQL - 192.168.1.4
  vcenter1 - 192.168.1.2

  I have 1 computer virtual created inside the Esx2 machine

  vcenter2 - 192.168.1.3

  I can ping all the machines in the administration server - no problem

  Question - I can not ping vcenter1 to sql, cannot ping vcenter1 to vcenter2, cannot ping vcenter2 to sql.
  There is basically no communication between virtual machines with the Esx host and in the whole of the host. Firewalls is disable on all these machines virtual esx internal hosts.

  Any ideas how to solve this problem?

  Make sure that virtual network on ESXi hosts maps are Sunrise promiscous mode networking.

• alternative vmkping for ESXi?

  Started the switch ESX ESXi and I'm looking for an alternative vmkping... tell powershell?

  I am aware of the possibility to activate the "unsupported mode" in ESXi, but I try to avoid doing anything that is not supported.

  With ESXi 4.1 'Tech support Mode' can officially be configured (enabled/disabled even with time settings) from the DCUI or the vSpere Client GUI.

  See http://kb.vmware.com/kb/1017910 for more details.

• Unable to ping ESXi 5.5 VM workstation 11 comments

  Hey all,.

  A lot of research and have not found good results. Currently impossible to ping to my VM ESXi from my Windows 10 laptop that runs 11 workstation.  I installed a custom VMnet (host only) with a specific subnet to the ESXi management interface. I loaded this VMnet even to my ESXi VM settings. I dropped my windows firewall, disabled the anti-virus software, disabled firewall ESXi and reconfigured NIC drivers to vmxnet3 without success. I know the VMnet I created works because I have an XP machine VMnet even we are able to ping successfully between my laptop and the XP VM.

  Any guidance would be appreciated.

  Fixed with the help of collaborator. I'm all new to VMware and I have a lot to learn.

  With the configuration, it is indicated in my previous post, I made the following changes.

  Modification of my trade to VLAN ID 0

  Configured for vmxnet3 NETWORK interface drivers

  I can now my computer vSphere mobile host in my ESXi 5.5 VM guest.

• How is it that I can ping between ESXi vmkernel interfaces with the sizes of package exceeding the value set in my passage upstream and one located in my vmkernel port group itself?

  
  I have a 10 GB dell powerconnect 8024f the switch and the firmware is OLD, but the port config shows maximum frame size = 9000 to all cable ports

  2 guests ESXi 5.5 wired, build 1331820, put each host computer network is managed by a single port dual qlogic 8150 ANC

  When I connect to my windows VM to check my new 10 GB connectivity (it is configured for jumbo mtu = 9000 frames) and ping-l 8190 against ESXi vmkernel interface that was MTU of 1500, I get an answer without any packet loss... How can it be if the port is configured for only 1500 MTU?  I thought that the two vmkernel port group and vswitch properties must have 9000 mtu defined, it appears that the vswitch properties override the port group properties.

  But I know I must be missing something, a few important concepts, somewhere, because when I connect to ESXi via ssh I can ping devices with values greater than 8190 and not just windows virtual machines that reside on the same host where the ping uses the internal bus, but I am referring to the connections of the host of other ESXi on the switch management.

  In summary - how the VMkernel does ping and response to pings of bigger sizes greater than the value of the switch upstream?   and why do ping with large packets get answers when the vmkernel port group is always set at 1500, is this a bug or is this feature obsolete?   I remember specifically in ESXi5 that I had to configure the vmkernel port group and the vswitch for this property to work.

  Unless you specify "Don ' t fragment" (-f for Windows) you will be able to use any size package successfully.

  For ESXi, take a look at Troubleshooting ESXi Jumbo Frames.

• two virtual machines on esxi, vm linux server can ping and ping to the outside, windows can ping but incoming requests timeout

  Hello

  I have an ESXI server with two network cards, each connected to separate the subnet in the same Cisco switch.

  First interface is in 10.231.5.0/255.255.255.0 and the second is 192.168.118.0/255.255.255.0

  Initially, I built a virtual machine with MS Windows 2003 R2 Standard with two network interfaces with static IP addresses on both subnets. 10.231.5.153(Gateway configuré sur cette carte réseau) and 192.168.118.153.  It has also installed vm tools.

  Second built vm is Ubuntu 8.10 with two network interfaces and two static IP a linux server in each subnet. This virtual machine has never had no problem contacted subnets one bit and he can go out on all of the subnets that are routable through the switch. Static IP addresses are 10.231.5.152(gateway est configuré sur cette carte réseau) and 192.168.118.152

  The Windows virtual machine has always been a bit flaky. Sometimes he would not be able to ping on all interfaces (while the State of the network in Windows showed the incoming and outgoing packets).  Sometimes he could ping another Vm and ESXI management IP but could not ping to the outside on the network 10.231.5.0 or 192.168.118.0. Deactivation and activation of network interfaces seem to make a difference with outgoing network access is enabled. However, if I try to ping back part of the same subnet a machine outside the ESXI Server ping timeout. It's weird as after having activated a deactivation of the network interface, that he even manages to ping subnets a bit far, but pingees machines cannot he ping back. However, these machines have no problem ping to the management of ESXI or Linux VM interface. Restart the machine virtual Windows translates the EPS of no longer being able to ping up to deactivation and activation of cards network again.

  I tried to activate the Promiscuous (the Accept value) mode on computer management virtual and vSwitch (vmnic1 and vmnic0 appear in the collection of NETWORK adapters window), but it did make a difference.

  Pointers would be very much appreciated.

  Thank you

• VMotion fails - vmkping does not work but does ping

  I got vmotion fail on the client of the vm (with current vmtools) trying to vmotion with disks (15 GB) of an ESX 3.5 up3 host to another host of up3 ESX 3.5... (the same two build...)

  has failed with the error: "failed to connect to host".

  1002662, 1005892

  so I check the KB and followed the documents there and made some typical changes to the host with both file list hosts in each of the other hosts file among the changed items.

  but no change... still getting an error...

  I don't know if this typical, but I can ping but not vmkping of one or the other host...

  what the meaning of the work of ping and vmkping does not (no route found host)?...

  Rpaker are you saying fall or remove the vswitch vmotion and time it?

  Bingo!  Yes, that's what I say.  Sometimes I get these strange and removal errors / time will fix it.

• cannot ping vmk2 on other servers with jumbo frames

  I had 3 servers esxi 5.1 configure each with 2 NICs vmk - vmk1, vmk2

  vmk1 is on fabA

  vmk2 is on fabB

  the chassis is connected to the FI and the FI, its goes directly to the heart of nexus 7 k. Frames is enabled on the core switches.

  I have CoS of vmotion gold and a Qos policy of gold with the default values shown.

  the problem is each esxi host, when I try to vmkping (vmkping s 8000 vmk1 or ip vmk2), the vmk2 of another esxi host, it does not. but the fact of vmk1.

  I checked my vmnic political and especially on fabB models and they are all set to 9000.

  any ideas here?

  I ping the host local esxi itself and vmk1 vmk2

  Tony,

  One of the things to keep in mind is that traffic of FI - A IF-E passes by the upstream layer 2 network site.  Make sure the LAN past what uplink you also have enabled jumbo frames.

• Virtual MACHINE is unable to ping host and vice versa

  It is a very strange problem.  VMWare support tried to understand this output as Dell.  So, I just throw it to the community to see if anyone else has experienced this problem and may have a solution.  I have 3 identical Dell R720 servers.  2 work with no problem, but 1 (let's call it vm8) gave me problems since day 1.  Reference verified Dell equipment today and has updated me the BIOS, firmware and drivers on vm8, which did not solve the problem.  VMWare technicians checked each parameter network in recent weeks and currently, they are not the cause.

  VM8 have ESXi installed 5.5.0.  The Server 4 has 2 NICs with 4 ports each.  Current configuration is vmnic 0-3 is connected to our LAN, 4-5 on our DMZ and 6-7 in our SAN (iSCSI). The AP will go up and down because VM8 loses connectivity to our isolation address (gateway).

  VM8 (Mgmt IP network is 172.20.100.9) has only 1 VM (172.20.100.40). Same subnet (255.255.255.0).  .9 happens to ping expiration.40 using vmkping.  When I ping.9 de.40, the first package gets a quick response, then all following packets timeout.  According to VMWare, when you ping in (VM to host) it does not go out through the card physical network to the physical switch.  Everything is internal with vmnic and vSwitch.  When I ping my gateway (172.20.100.1), the ping is successful.  When I ping.9 from my workstation, the first packet times out, then answered the following packages.  It is the exact opposite of ping the virtual computer.

  Here's a better ventilation-

  .9 VM8 host

  .40 VM on the host VM8

  .1 gateway

  .122 workstation over LAN

  .25 vRanger connection (physical server on LAN)

  Ping

  .9 40 (100% packet loss)

  first package de.40 a.9 (75% packet loss) Gets the response, then 3 timeout

  .9 a.122 good ping (0 packet loss)

  .122 a.9 (0 packet loss) good ping

  vmkping (75% loss).9 a.25 does not appear each packet that it is sent.  But other results, can I assume first package times out.

  first package de.25 a.9 (75% loss) has expired, the following 3 got a response

  .40 a.122 good ping (0 packet loss)

  . 122. 40 (100% packet loss)

  The 3 can ping a.1 (every 20 minutes on VM8 I get a "vSphere HA agent on this host failed isolation address 172.20.100.1"

  Also, throughout the day, I get the message - "vSphere HA agent on this host cannot reach some of the management of the addresses of network of other hosts, and HA is perhaps not able to restart the virtual computer if a failure of the host is displayed."  I came to work in the morning, and all my VMS on VM8 migrated to my other 2 hosts.  My backups don't work on VM on VM8.  I use vRanger connection and when I ping connection vRanger VM8 (physical server), the first package expires and the following packages get a response.  Then, when connection vRanger goes to back up my VM, runs aground due to loss of original packet.

  These are things I've already tried.  I tested individually each physical NETWORK adapter.  I removed all the ports on the two NIC to try to isolate a specific port. All the 4 vmnic is active adapters in network properties NIC Teaming management and I moved each vmnic individually to unused to test each port.  I replaced the Cat6 cables.  I used different Dell switches and various ports of the switch.  I even swapped the switch ports that host another employee, exclude a switch port configuration problem. In addition, port security is disabled on the ports.  I upgraded ESXi 5.5.0 to a newer version.  There is a known issue with the tg3 driver, which I've updated to the latest version without problem.  I also used tg3 workaround by disabling NetQueue.  And we do not use of VLAN. Dell technical support says that it is not a hardware problem and thinks it's a matter of layer 2, but does not know where.  Basically, it's an internal problem (meaning strictly on VM8) with vSwitches or vmnic or it's a material gremlin in our Dell R720 box.

  The final recommendation of Dell is to blow the ESXi server and install a clean copy.  It's extremely frustrating and I'm out of ideas.

  Thanks in advance.

  Any luck that you have an IP address that is duplicated on your network?

• Cannot add 6 ESXi to vCenter

  Hello

  I hope someone can help, I'll through in circles!

  I am using ESXi for years, but always as unique hosts. Recently, I obtained a license for vCenter 6 essential elements and put on the creation of a laboratory.

  
  

  I have two ESXi hosts, a Mac Mini (192.168.1.0/24) and a Dell PowerEdge (192.168.10.0/24), the two v6 ESXi running. vCenter v6 is running on a virtual computer on the Dell Poweredge server and works. Can be connect/license/administer etc. Also, I added successfully to the Mac Mini to the new data center.

  
  

  However, I can't add the Dell Poweredge server. Whenever I pass by the host process add I get the following:

  
  

  "Unable to contact the specified host (hostname.domain.local). "The host may not be available on the network, may have a network configuration problem, or that the management on this host services may not respond"

  
  

  Also, when I have RDP on the vCenter virtual hosting machine I ping the server Poweredge ESXi by IP, host name and the FULL domain name, but I can not connect to it via vSphere Client. However, if I use my laptop (192.168.1.0/24 range GOLD 192.168.10.0/24) I can correctly connect the Poweredge ESXi server.

  
  

  Can I add a host ESXi, vCenter vCenter is running on this host?

  
  

  Any help would be appreciated!

  Can I add a host ESXi, vCenter vCenter is running on this host?

  Yes, you can, but you must ensure that the appropriate network ports are open between ESXi and vCenter. VCenter Server both the ESXi (to PowerEdge) are running on the same subnet?

  Found the problem as vCenter 6.0 version I was running. I was running an older version of the VC and the current version of ESXi.
  Downloaded the current version and reinstalled and all good.

• 5.5 ESXi

  Hi all

  I'm a new student who is very interested to learn from VMware. Now, I am facing a problem that I didn't know. I installed two hosts, windows 2012 server and the other is darn Linux and none of them is able to connect to the internet.

  I can't even ping the gateway. Could someone please direct me the problem and how to fix it.

  Please, check references on attachments.

  Thank you for your help and have a great day.

  Are you able to ping network management VMS ESXi host address?

  What type/model of physical switch are you using? Some switches have port security enabled by default, which restricts the number of MAC addresses that are allowed on a single physical port.

• After that stright connected to iSCSI (initiator) Host cannot ping the server iSCSI (target), but the target can, why?

  After that host on vSHere 4.0 strightly connected to iSCSI (initiator) host cannot ping the server iSCSI (target), but target can.  And iSCSI works well. I mean I can create and use the iSCSI disk, why? It makes me confused.

  Thank you!

  Geoarge,

  iSCSI traffic uses a VMkernel port, instead of using the command 'ping', use 'vmkping '.
