• Advice on how best to configure the network adapters and virtual switch in ESX host

  I'm new to VMware and am its implementation.  I got my training a few weeks ago, and now I'm configing my hosts.  I have 3 guests, each have 2 network cards.  There is a virtual switch that ESX creates when it is installed (vSwtich0).  The books said that it is advisable to delete the VM network port of virtual machine that is assigned to the value group default virtual switch and put it on another virtual switch so that you keep your management network separated from the network of the vm for performance and security.  If I do this, all my virtual machines will have to go to 1 NIC b/c I only have 2 NICs per host.  I thought that I have just to keep all my groups of ports on the default vSwitch0 and add my second NETWORK adapter so that I can take advantage of the Association of NICs for redundancy and load balancing.  However, I'm not sure on the performance and the security risks.  Do you have any ideas or advice?  I could also create two virtual switches and put my virtual machines on one which would have a NETWORK card dedicated and put my service and Kernal VM console on another virtual switch with a dedicated network card.  However, in this scenario, I have no fault tolerance or load balancing.  We are a small shop and we have about 10-15 VMs on each host.  I don't have access to b/c distributed switching we paid only for the company (not more).  Thank you.

  Hi and welcome to the forums,

  With 10-15 VMs per box and I guess that I would seriously consider adding two extra cards for each host in the production machines. You could then do something like:

  vSwitch0 - vmnic0, vmnic2, vmnic3 - Console of Service, VM LAN network

  vSwitch1 - vmnic1 - VMkernel

  That would give you redundancy and performance to access your hosts (SC) and also for all your virtual machines. The VMkernel would get a NETWORK card dedicated for vMotion and could be on a separate network. He didn't need redundancy really as if the NIC sank the only issue is that you cannot vmotion virtual machines. In this case you would just move one of the NIC workgroup through to those switches manually.

  If you only have 2 network cards, then I would say having a vSwitch with two attached network adapters and VLAN the VMkernel may be off. I want absolutely to the redundancy of having two cards together.

  Hope this helps,

• Grouping of NETWORK adapters and NLB on ESXi 3.5

  I want to get ESXi to load balance the traffic to my NFS storage, but have had no success. My test set up is the following:

  • Two blades each with two physical network adapters dedicated to the ESXi for NFS kernel ports

  • Two switches

  • A NETWORK adapter on each blade is connected to each switch - it isn't an Etherchannel or trunking configured

  • Two NFS devices on a different IP address

  • Eight virtual machines on each blade, four to connect to a data store on each device of NFS

  • ESXi NIC teaming across two network cards with the option "route based on the virtual origin of switch port code.

  My understanding is that each virtual computer must use one of the network cards, but about half must use a physical NETWORK card and half the other. Instead, all the traffic of all eight VMs released a physical NIC if I disable the physical NIC, it moves the second NETWORK card without problem. Then they both work, but he never uses both at the same time. This behavior is consistent across the two blades.

  Is throughbut limited to ~ 110 MB per blade and the storage system can easily exceed this.

  I've attached a screenshot of a virtual switch in place.

  TIA,

  Will be

  Virtual machines are access NFS data warehouses directly? If Yes, then yes it should work that way - however if you are using the NFS data store to host the VM files, including virtual disks and then traffic will turn off the vmkernel port and if have vmkernel unique port then what you are experiencing is expected - the vmkernel selects the outgoing NIC based on the virtual port id so if you have a single port vmkernel will suffice a single port as well as a NETWORK identifier unique will be used.

• Network adapters and VLAN (optional) shaded in DCUI

  I'm studying for my VCP exam and I use a nested in workstation installation. Suddenly I don't have access to the network adapters in the DCUI. I've migrated the two network interface cards used for the management of a group of management vmkernel ports in a distributed switch.

  Anyone know what is happening here? Google gave me this indication Configure networking Greyed in DCUI
  

  But in my case, the hosts are always connected to vCenter and work fine no problems anywhere.

  

  As you migrate your management VMkernel service VDS, all virtual switch tasks, including managament VMkernel configuration interfaces / VLAN must be done on vDS and not on ESXi.

• Problem with external network profile and DHCP

  Hello

  Is it possible to create a network without IP range profile, in order to use the external DHCP protocol.

  If I create a network without ip range profile I got this error when I submit an application VM:

  [catalog] Com.vmware.vcac.platform.rest.client.error.ResponseErrorHandler.handleError:55 - [error rest] ERROR: {status code: 400}, {error code: 42300}, {error Source: null}, {Msg of error: a server error occurred.} Error the applicant unit. {The list of unallocated IP addresses for the network profile (mynetworkprofile) has been exhausted.}, {System Msg: error of Infrastructure service provider}

  I'm sure we can do it, but I don't know how

  Max

  Simply create the profile of any network. Just assign the reservation with the network that you want to use, and the virtual machine will get his IP from the DHCP server.

  vCAC will not be able to manage these addresses because DHCP manages them--if that's what you want to accomplish...

• 5.1 ESXi management no connectivity network with two network adapters connected

  IBM H chassis equipped with blades HS22

  Blades use Broadcom 5709 s dual gigabit NIC

  ESXi 5.0, system worked very well with both NICs connected (static IP) in network management parameters (able to ping in and out). Completed the upgrade to ESXi 5.1 preserving VMFS datastore. After the reboot, management network shows two NICs connected to static IP always assigned but I have not any (impossible in our out ping) network connectivity. If I disable one of the network cards and restart the management network, I can immediately ping inside and out.

  I took a spare blade and tested by passage of 5.0 to 5.1 and 5.1 installation clean, the two producers same results. A host with two active network cards 5.0 (if static IP or DHCP) can ping inside and out. A host with two active network cards 5.1 (if static IP or DHCP) can not ping in our out. 5.1 host cannot obtain DHCP address, but fails to APIPA.

  I found the problem. For some reason, both switches must be actively connected on the same network for observed networks provide correct information for the collection.

  Hello:

  According to the list of parts for your laptop, it has an Atheros wireless with bluetooth card or a wireless card broadcom Bluetooth, so those who are the only two drivers without wireless/bluetooth, you should try.

  It would be better if you knew exactly which Wireless adapter you have, so there is no worry about the bad driver causing the problems.

  HP wireless assistant software is not compatible with your model.

  Your model uses the latest Connection Manager HP software that does the same thing, as does the HPWA software on notebooks.

• Unable to connect to the internet with the NETWORK card and Windows Millennium Edition.

  Hello

  I turned on my old computer yesterday, who has installed Windows Millennium Edition. At the back of the computer is an Ethernet port which is marked as LIEN ACT. The NIC with this port is Realtek 8139 PCI Fast Internet Adapter. I spend two hours on the Internet configuration and I did and finally got connected, but then, a few hours after, something went wrong and the Internet and the NETWORK card has stopped working! And the card has disappeared from the Device Manager, but he's still showing in network in Control Panel. I opened the computer and I reconnected it to the slot, but it did not help. At the back of the computer next to this port are two LEDs - green indicates the power that lights up when I plug the Internet cable and the other orange indicates actual connection. But now these two LEDs are not indicating something even when I plugged in the cable to the Internet, which comes from my router. In the computer a Dial Up connection PCI is installed too, but I disabled it. I used Dial-Up in 2002. So, I need help.
  But I know that I can connect with this Ethernet card to the Internet because it worked for 3 hours, I've loaded the pages and downloaded programs.
  Please don't point, should I upgrade Windows!
  Thank you.

  Hi friend,

• Photosmart Premium C309G not detected during installation with wired network connection on Win 7 64 bit

  During the installation of the drivers and software on Windows 7 Home Premium 64-bit computer laptop, (previously upgraded from Vista), the installation software can't find the Photosmart Premium C309G, even if I provide IP address, that is on the same subnet. Same printer installed on three other computers on the same network for Windows XP. It is possible to find via windows 7 Add Printer function by using the appropriate base driver, but then if I try to print, it cannot print the test page, printing garbage, after much time and erases never status "printing" in the queue until I manually cancel. There is an Ethernet cable on the home network.

  The first thing to check is your firewall.  Disable the Windows Firewall and the firewall of your security system and try the installation again.

  If you had this printer installed on Vista, you can simply add this patch.  It's only for the patch software Vista works on Win 7, so if this is not the case, do not take into account.

• The message that it is has no network adapter and not configured. What's wrong???

  I have a Gateway LX6810 - 01 desktop runnning windows Vista Edition Albums Home Premium, 64 bit, 8 GB of RAM, all the latest updates and Service Pack 2. I connect to the internet through the network connection AT & T Uverse high-speed broadband (12gbps). He worked for over two years now with no problems until now. All of a sudden one day after I rebooted the machine there is no internet connection. When I went to the network and sharing Center, I receive a message that there is no installed network devices. SO, I went to the Device Manager window and there is no device listed network but when I opened the "hidden devices" he has been. (Why it is hidden I have not the slightest idea). SO, I went to the BIOS and checked for if ensure the LAN has been "activated" and it WAS.  I don't always get the same message "no network installed devices. SO then I went on the website gateway and downloaded the driver LAN for my machine and my LAN and reinstalled the driver... I ALWAYS get the same message and I still have no Internet connetion. WHAT could be the problem? Although I consider myself relatively smart, I'm NOT a computer guru, so be kind and state your suggestions in the jargon of the 'no' then I'll understand.

• Moving from a static network to and auto IP network

  I'm running Vista 64 home premium on my lap top. At my office, I have a router linksys running on a static IP address. At home, I use a router linksys on an IP to auto. Windows seems not to be able to tell the two apart, he still thinks it is the router to work and I have to go the IP4 setting and set it to automatic. When I go to the Office I have to go back for the IP4 setting and set it to static and re-enter-the all the info and safety. I'm at whits end with this and any help would be great.

  I set up a network for each at each stop. Even if I select what I want, I still have to change the settings.

  The office is secure and reception is open and those affecting must be changed also.

  Hello

  Since you are using a single network adapter for the configuration of static and dynamic IP addresses, it is not possible to switch the IP addresses automatically on the same network adapter. However, you can use two network adapters and configure the static IP address on the an and a dynamic IP address on the other network card that should solve the problem.

  Alternatively, you can also use a network Ethernet controller to configure the static IP address for the office and a wireless network adapter to configure the dynamic address access to the House.

  Hope the helps of information. Please post back and we do know.

• Fusion on Mac Pro - dedicate a guest only NETWORK card (and have the OS ignore)

  As the subject says. Such a thing is possible?

  I don't know if I'm looking in all the wrong places, or just to ask the question properly.

  Here's what I was wondering:

  I have a Mac Pro with two network adapters. I want to use one for the host (OS X) and the other only for the guest OS. And using it for the guest OS, I want OS x to ignore it completely.

  If possible, how to apply such a facility?

  1 OS X > system preferences > network > Hardware icon > set order of Service

  • In the Service order worksheet, have the NIC priority placing the card NETWORK to use for the host at the top of the list, followed by the NETWORK card dedicated to the virtual machine, and then click OK.

  2 OS X > System Preferences > network

  • Select the card NETWORK dedicated to the virtual machine, and then to configure IPv4: stop selection, then click on apply.
  • Then to configure IPv4: check the DHCP with manual address.
  • Then for IP address: use a reserved address of 169.254.0.0 to 169.254.255.255 IANA Internet Assigned Numbers Authority () and then click on apply.  It's the range of addresses for the automatic private IP addressing, which normally would be affected if the NETWORK adapter does not have a connection but not to worry, it will be... only for the bridge of VMware which will be defined in the next step.

  3 target Virtual Machine settings > network adapter > Bridged Networking, select the NETWORK adapter chosen for the use of the dedicated virtual computer.

  • Now the Virtual Machine will acquire its network router for the LAN Host Configuration information, or you can assign an address appropriate static IP, mask, subnet, gateway and DNS server IP addresses in the configuration of NIC in the guest OS if you wish.

  Note: If this doesn't work for you, even if as described, it works for me, you may need to manually select to configure IPv4: and use a reserved in the meantime address previously mentioned with a 255.255.0.0 subnet mask while providing the appropriate Host router LAN Gateway and IP addresses of the DNS servers.

  Another problem can occur if using a WiFi NIC dedicated to the virtual machine, some WiFi routers will not fill several IP addresses to the same MAC address.   If this is the case for you, then you will have to use wired Ethernet for NETWORK adapter dedicated to the virtual machine!

• ESXi 4.0 host network adapters

  I'm kinda a noob here, so forgive me if this is a stupid question. I have an ESXi host with two network adapters. My configuration is to have an adapter connected to the Internet and an adapter connected to my internal network. I want to do in order to implement an router ISA in a VM and use a NAT to clients internal and other virtual machines. Is this possible?

  I thought it would be as simple as the external adapter with DHCP configuration to obtain the address of my ISP and configuration of the adapter internal staically and then simply using vSwitches to connect the adapters with my computers invited to use the appropriate physical card. The problem is that when I go in the shell of ESXi, you can only configure dynamic or static for the management network and there is no options to configure two adapters separately. I see my internal adapter properly configured with a static address in the vClient, but the external adapter shows a range of IP addresses observed of 10.229.128.1 - 10.229.129.254. Where did that come from? Do I need to use the command-line utility to configure this? If so, what commands can do that? Thanks in advance!

  No need to reboot the host. Basically, all you need are two vSwitches. The first one connected to the LAN internal groups of 2 ports, one for the VMKernel (with the configured IP settings) and one for the network of the Virtual Machine. The second vSwitch only requires a Virtual Machine port group.

  Configure the virtual machine (your router ISA) with two network cards virtual, a related internal and external vSwitch. Make sure the settings for virtual network cards are set to "Connect at Power On" and are in the 'connected' State when the virtual machine is up and running.

  Depending on your ISP, you should get a DHCP IP address on the external vNIC by configuring it to "Automatic" in the guest OS.
