• Best way to migrate virtual machines to new ESXi hosts with a different configuration of networking.

  We currently have a cluster of 6 Dell machines that move VM 120 or so on ESXi 5.5. Networking consists of a dVswitch with 6 uplinks that map to 6 x 1gig physical NETWORK adapters on each host ESXi... These are grouped into 3 trunks / gal, so we have 2 GB by SHIFTING of the bandwidth and failover. The LAGS are configured as follows:

  LAG1

  Traffic to our (NFS) shared data store and management of ESXi. (vmk0)

  LAG2

  Access to the network of the VM - groups of different ports on different VLANS

  LAG3

  vMotion (vmk1)

  We just bought 6 new Dell machines that have connections fiber 2 x 10gig each. The idea is to bring together in a 20Ggig LAG by machine that will handle all of the traffic, so traffic NFS data store, network traffic from the VM, vMotion and traffic management ESXi.

  
  

  What is the best way to migrate the virtual machine in the cluster existing to the new machines? Many of the virtual machine are essential, so we cannot stop time.

  
  

  Can I create the new DELAY on existing dVswitch and put it as an auxiliary card? I'll be able to do it for all 3 of the above both above LAGS?

  
  

  Thanks for the info Alistar, it's almost here. The bit that was me stumping was that after establishing a new dVswitch I received messages that the new dvSwitch was not reachable on the old host, when I tried to migrate the virtual computer.

  The solution (with the permission of VMware Support) was that I need to add the two dVswitches to one of the old hosts, then assign a physical alternative on this host uplink to a temporary 3 uplink on the new dVswitch. I then tag all the relevant VLAN that uplink.

  This way I can first migrate the virtual machine to the new dVswitch networking so I can move the computer to the new cluster.

  Obviously I can only migrate from old to new cluster with a single host. each virtual machine must be a double for the host with 2 switches, and then to the new cluster. I also had to have the two dVswitches to the same version.

  Fortunately, I had a physical rising spare on the hosts of the old, otherwise I would have had to break one of the trunks and re-use of one of these uplinks.

  Oh and be aware, impossible to use the same names for groups of ports 2 DV switches, they must be unique!

• Slow network traffic / expires at ESXi4 host starting from a different subnet, but customers are very well

  I set up a test server ESXi4 and spin various Windows 2003/XP clients and a guest of Vyatta VC5 as my core router.  This has been a strange problem that all traffic to the guests and also are very good, but I can handle only the host with the VI client on the same subnet.  If I can host on a different subnet (even if I leave the cable connected to the same port and vlan), then it becomes unusable.  Many things time out including just trying to download the VI client from the host https page.  Anyone seen this before?

  I have 2 configured vSwitches, one on one vlan isolated to my iSCSI traffic to my storage, and the other as a trunk with the VLAN network management and guest vm on it.  My management network is in the same vlan as one of my comments to VLAN.

  Thanks in advance.

• Cannot access ESXi host in Vcenter after moving to accommodate different subnet

  I moved a different host EXSi 5.5 on a new subnet at a physical site.  The host has been identified by IP not the DNS name.  After the start of Vcenter, I realized my mistake.  The host is always identified by the old IP so it appears as disconnected.  I was hoping I'd be able to simply change the identification of IP address, but have not been able to see how to do this.  I also tried to remove the host (this configuration has a data center and a host), but I can't do it.  I can't add the host (with the new IP address) I get an error message that the data store is identified with the original host.

  Is there an easy way to this?

  Welcome to the community - you need to remove the old entry in your inventory (using the command delete inventory) and then re-add the ESXi host FULL domain name.

• vMotion between hosts on different subnets

  Before you start, I'm a network engineer, not a server guru, please bare with me

  Is it possible to vMotion a virtual machine to a host on an IP network to another host, on a different IP network?

  Example:

  Data Center 1 - 10.1.1.1/24 with VM in the 10.1.2.0/24 ESX Server

  Same city, different site, binding fiber 10 GB between facilities 2ms latency

  Data Center 2 - 10.2.1.1/24 in the 10.2.2.0/24 with VM ESX Server

  Scenario:

  vMotion a computer virtual network 10.1.2.0/24 to the 10.2.2.0/24 network where virtual machine, on arrival on the ESX 2 data center server, now uses a IP address of 10.2.2.0/24.

  Any guidance towards a white paper or a guide would be greatly appreciated.

  Thank you all for your time.

  vMotion is possible between hosts on different subnets, but unless your discussions presented to the virtual machines are on the same subnet, you will eventually drop the virtual machine on a VLAN different and IP addressing will fail.

  There are ways around this, you could script the change of IP address / present several IP addresses of the virtual machine / or reservations DHCP to use, but you will need to ensure DNS etc. records are updated.

  If you have some kind of load balancer, you could in theory balance workloads on 2 IPs hosted on the same VM, to solve the network ip address issues, although in the end, you'll want a VLAN tended to port VM coverage groups.

  Good luck

• Allowing access to ESXi host to other subnets

  Hi all

  I use the free version of ESXi and it is in course running on the network. 10.32.125.x I noticed that if I try to connect to the host via the Client vSphere from another network, such as 10.32.126.x, I can't.  I can't ping or SSH host either form the 10.32.126.x network.  All right if I'm on the 10.32.125.x network, which is the same network that the server is running on (10.32.125.63 is the IP host address).  I can access services on thin virtual machines from other networks, just not the ESXi host itself.

  Any ideas of how I can allow access of networks other than that on which lives on ESXi?

  Thank you

• 5.1 ESXi host is showing that does not

  Hi all

  We are to vCenter 5.5 with Environment 5.1 ESXi hosts. On one of our ESXi hosts, we sometimes get to see 5.1 ESXi, (build 799733) host is not responding and the virtual machines on this subject are displayed as status disconnected at the end of their names.

  When this happens, we are able to ping on the ESXi host and virtual machines are also able to ping / react to what is good, but he continues to be on different hosts at different times, all what I do when this occurs is to try to reconnect on the ESXi host and it connects fine and machines virtual hosting on she will return to the State normal and everything will be normal on this host. I want to understand why this is happening at different times and on different hosts of ESXi and ensure that this should not happen again in the future or find the before root cause is even worse.

  so, could someone please look at this and let me know where to start troubleshooting this to find the root cause.

  Thanks in advance

  Your vCenter and ESXi host is on the same subnet? In any case, I recommend you take a look at this article and apply the patch suggested: VMware KB: hosts ESXi and ESX disconnect randomly VMware vCenter Server

• Setting up a virtual computer on a different subnet?

  How to set up this configuration is all new to me.
  Current context:
  Internal subnet: 192.168.1.x
  2 - 5.5 ESXi hosts. Each with 4 physical NETWORK adapters
  Configuration is attached.
  I have a physical server I want to virtualize but is in a different subnet.
  Replacing the subnet: 192.168.10.x.

  I reason assuming that I'll need to add a physical NETWORK card to each host and assign this NETWORK adapter on the computer virtual requiring a different subnet? Or am I way off?

  Thanks in advance!

  If your physical switches supports VLAN's then I would say you think to reconfigure the ports for the ESXi host and tag/trunk ports to the VLAN necessary. And create groups of ports VM with the differnet VLAN-ID on the ESXi host. In this way, you can use different subnets on the ESXi host without the need for having dedicated physical rising for each subnet.

• 5.0 ESXi hosts all say "not responding" after a while

  Hi all

  First of all, yes I know this is a repetition of something that is posed before but I tried all the resolutions that I can find - nothing has worked so far.  In the vSphere client, all hosts currently have a status of "not responding". For reference, however, here is what I have tried/checked so far:

  -vCenter and ESXi are all in evaluation mode.

  -I do not use the brand HP ESXi ISO (as referenced by http://communities.vmware.com/message/1852500 more numerous other positions of the community).  Material * is * HP hardware, though.

  -Change of the security policy of vCenter Server (as referenced by http://communities.vmware.com/thread/271809).

  -Go through all checks VMware published listed in http://kb.vmware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1003409.

  -Network connectivity verified using PING, nslookup and telnet on port 902.  All ESXi hosts respond on port 902.

  -AD DNS monitoring verifies that all say "Pass".

  -There is no firewall on the network (it has physically isolated from everything, including the internet... obviously I am writing this post on another network).

  -Direct connection to the ESXi hosts works very well - this only happens when connecting through vCenter (so running virtual machines are available and usable without any problem... There is no HA).

  -/etc/VMware/VMware.LIC has a license of '0' key (confirms the status of the evaluation, I think).

  -/etc/vmware/vmware.lic mode is the following... - rw - T.

  -All hosts are on the same version of ESXi.

  -There is only 1 Server vCenter.

  A strange thing is that some items, including VMware ones, say to run 'rpm' and 'service' in a variety of different ways.  'Rpm' or 'service' are valid commands on my ESXi servers.  This seems odd, unless ESXi 5.0 withdrew these commands to the shell.

  Can anyone suggest anything else that might be the cause?

  Thank you!

  If VC is virtual and the problem that happens on the same ESXi what they are and all on the same subnet, I am almost sure that something on your windows it blocks. Check the steps in KB http://kb.vmware.com/kb/1029919 to try to discover what is happening.

• MD3220i - install the drivers 'to host' on ESXi hosts

  We bought a MD3220i to use as shared to our vmware datacenter storage.

  I'm a little confused by the documentation...

  She says that she needs to host software installed on each host that connects to the MD3220i and the software grouped: the driver agent and multiple paths to storage. And that any host servers that connect to the storage array need.

  Without doubt, this also includes ESXi hosts?  If so - how do install on ESXi hosts?

  Or I completely understood you something here...

  Advice would be appreciated,

  S.

  You have no software special 'host' because all the parts needed is already bundled with vsphere ESX (i). The essential parts are to check if the right HOME is used and that configure you the initiator of swiscsi in the right way. In terms of vsphere4 you need some Voodoo (remote control) command line to use esxcli to bind the VMKs created together.

  Reference Dell have a best practice on how to connect the md32x0i to vsphere which has been found at the momemt. The guide shows the ip network configuration and all the necessary parts in vsphere. Dell uses a subnet of grand for all ports of 2 controllers. If you are looking for in this forum you will also find configurations where a single subnets are used to place a port for each controller. The two works configuration but I do face "LUN is not on preferred path" errors from time to time during the use of the first installation.

  If you call technical support Dell will send you the necessary guide but I do not know google can help as well. Its like for many other iscsi bays and rules applied (several VMKs, binding, etc.). If you can't find something I can dig in my Inbox if necessary.

  Edit:

  OK... after a google search hard that I found the former guide who use a single subnet, but the guide describes the installation with different subnets. Then you should follow this path. Take a look at http://www.dell.com/downloads/global/products/pvaul/en/md-family-deployment-guide.pdf

• Running the software iSCSI on a different subnet than the management traffic

  I hope I'm missing something obvious you smart people might be able to help with.

  I am trying to put in place a small instance of vSphere using ESXi 4.0 Update 2 and unlike most of our environment, we use the iSCSI instead of fibre SAN storage.

  The intention is to set up a network on subnet A, for management and Vmotion traffic which will have 2 natachasery attached.

  We have a second 'B' allocated for iSCSI storage subnet and have 2 separate natachasery which will be implemented through two vSwitches, 1 Teddy for each.

  We have implemented the switch management/vmotion on a subnet and, of course, the default for this subnet gateway entry when asked.

  The iSCSI subnet naturally has a different gateway and so when I entered IP address on subnet B in the port of core, it seems always trying to route through the gateway to subnet an attack to storage not being is not visible.

  We have verified that the problem is not with the storage or the ESXi put in place by proving that if we give the iSCSI port IP subnet A (and also the storage) then we can see storage without problems - simply, the question seems to be everywhere to try to operate on a completely isolated subnet.

  Isolation of storage traffic is a customer demand, and not something that we cannot ignore.

  Anyone know if it's possible (and if so what should I do to solve the problem) OR should we look for to move to ESX Classis and use his ability to use 2 different gateways?

  I feel that I must be missing something pretty obvious I don't know there must be a way to achieve segregation of traffic on subnets for the other core activities such as vmotion, fault tolerance and management traffic.

  There is only one door of entry for VMkernel, then you can separate VMotion / iSCSI / fault tolerance than if not routable subnets, i.e. all hosts on the same subnet.

• several networks on esxi host

  Is it feasible to have virtual machines belonging to different subnets on the host single esxi?

  For ie) Esxi host has 3 network cards

  VM machine 1 belongs to the 10.10.10.0/24 network

  VM machine 2 belongs to the network 10.10.20.0/24

  VM machine 3 is part of the 10.10.30.0/24 network

  I just need to create 3 virtual switches for each network on the ESXi host and machinery VM 1, 2 and 3, assign the IP address accordingly?

  Then the machine 1, VM on the machine itself, assign 10.10.10.10/24 and VM Machine 2, grant of the 10.10.20.10/24 and VM Machine 3, 10.10.30.10/24 and routing will be supported by the ESXi host?

  Or do I need to create default routes on the ESXi host or VM machines?

  If you use a VLAN, do I need to specify the VLAN ID, when the creation of the virtual switch within the ESXi host?

  Since you use vLAN tagging to the vSwitch level rather thean the virtual machine port group level it will work as long that virtual machines are connected only to their approriate vSwitch configured to their vLAN.

• Target subnet mask and the gateway in different subnets and clock error

  Hi all:

  Need help. I have a standalone PC operating a direct VI on a CFP with a crossover ethernet cable (developed on my laptop, compiled and installed as a standalone on the PC). When the VI runs on standalone PC version, everything works (click the button, analyzers are read), but the time being pulled from the CFP is wrong, and infact resets to December 1969, a default value. I am error checking, and no error is marked with the CFP, slaughter programmes. When I go to the MAX function, the time playing of the CFP is the funky time. Looking at the IP addresses, I generally use a very standard protocol (192.168.000.001 for the PC, 192.168.000.002 for the CFP currently running on the subnet for the pc and the PSC 255.255.255.000). However, when I apply this Protocol on the CFP through max, it gives the error "the subnet mask you entered puts the target and the entry door to different subnets." I am not versed enough well understand this, and what I read in 2 postings here, I tried to harmonize the IP numbers and the subnet, and they do not seem to help. When I put intentionally in false numbers IP or subnet default time synchronization time correct (pc), but functions block (as expected). It is certainly not an issue of PC zone.

  Anyone can offer any guidance?

  Currently runnig LV 8.2 with drivers of 2009. PSC 1804 with MAX 4.6.

  I appreciate all help.

  Best regards;

  GIS.

  OK, I solved it. FYI: for those who are not aware of the IP: IP of the host and default gateway server to the same value. My work for the host computer are 192.168.000.001 and subnet masks can stay 255.255.255.000. The CFP has been set to 198.162.000.002 with a 90.00.00.03 DNS. Time server has been blocked by the Norton 2009 Firewall (even with an exception) and thus the cruxt of this issue together. I had to uninstall completely from this "software". I hope this helps.

• OME 1.3: update R910 5.5 ESXi host through iDrac fails

• RV180W ping hostname between VLAN & different subnets

  Hello

  I had a RV180w with 1.0.3.10 closes. According to the name of position, I'm not able to resolve host names between different VLANS which affected to different subnets, for example, allows said I have the following hosts:

  CASA:

  192.168.241.100/25 (wired - VLAN 1)

  Router: 192.168.241.1

  DNS: 192.168.241.1

  XBMC: 192.168.242.100/25 (Wi - FI - VLAN 2)

  Router: 192.168.242.1

  DNS: 192.168.242.1

  If I try to ping from two sources to one of the two destinations, the only one I get is a message 'impossible '.

  Authorized additional information routing between vlans & proxy DNS and if I try to look at the hostname under the 'nslookup' command, I could not resolve the host name, but if I do a "ping - a 192.168.241.100 ' it is said ' response from CASA (192.168.241.100) blah blah blah."

  So what I'm missing here?

  Hi Bruno, you can usually solve different subnet host name because the host does not know the subnet that treats it as a security measure.

  Disable the firewall feature on your computers and which must fix, otherwise you will probably have to change the lmhost files.
