• Two virtual machines running on a same PC network

  Hi all:

  I'm running both SUSE Linux Virtual Machines (VM) with VMPlayer on a PC with Windows server 2008. The two virtual machines are configured to the bridge at the same host physical ethernet port (bridge mode). Started the first virtual machine can access the network without problem, but the second VM started not. The order from VM has been changed in order to check if it was a configuration problem on one of the virtual machine, but according to the virtual machine that is launched in the first place seems if appropriate switch VMnet0 and block access to the second VM. Defined for each virtual computer LANs are different: 10.2.1.0/24 for a VM and 10.4.1.0/24 for the other.

  Any help will be really appreciated

  Case resolved, I realize that he had a message waiting in the toolbar of VMware by saying * adapter Ethernet0 do not have network connectivity. MAC 00 address: 0C: 29:58:61:19 adapter Ethernet0 is located between reserved address or is being used by another virtual card on your system. *. I just checked on google and found an identical case on the VMware communities with the solution: http://communities.vmware.com/thread/269465?start=0&tstart=0. To make the story short my VMs have been duplicated and used the same MAC address. So just stop a virtual machine and generate a new MAC for him in settings-> settings-> Advance-> ECS

• Two virtual machines on the same vSwitch

  If two virtual machines are on the same virtual switch, will they still send packets on the physical wire when talking to each other?

  It was my understanding that they would not send all packages and contain just the vSwitch traffic but I would just check that.  If they are not, is it possible to configure it so that they do.

  Thank you.

  Given that the vSwitches are not connected to each other, you need physical uplinks.

• You can force two virtual machines to run on different hosts?

  I'm looking to see if we can score two virtual machines to never run on the same host as the other. I thought I had seen this ability in later documentation but can't find it now.

  Thanks for any help!

  Hello.

  If you use the DRS, then you can use a rule of DRS 'separate virtual machines.  Go to the Cluster settings, change, then see the VMware DRS-> section to implement rules.

  Good luck!

• NLB - two virtual machines can't ping eachother when on separate hosts

  Greetings,

  I've been running some tests with NLB on the different desks as recommended here:

  http://KB.VMware.com/selfservice/microsites/search.do?cmd=displayKC & docType = kc & externalId = 1006558 & sliceId = 1 & docTypeID = DT_KB_1_1 & dialogID = 42912404 & StateID = 0% 200% 2041454115

  http://KB.VMware.com/selfservice/microsites/search.do?cmd=displayKC & docType = kc & externalId = 1006778 & sliceId = 1 & docTypeID = DT_KB_1_1 & dialogID = 42912404 & StateID = 0% 200% 2041454115

  I found that Unicast works better in our network environment, but it is still a problem:

  In http://KB.VMware.com/selfservice/microsites/search.do?cmd=displayKC & docType = kc & externalId = 1006580 & sliceId = 1 & docTypeID = DT_KB_1_1 & dialogID = 42912690 & StateID = 0% 200% 2041454807

  He says: "since all hosts in the cluster have the same IP Address and the same MAC address, there is no communication possible inter-hote between the hosts configured in unicast mode.» A second NETWORK adapter is required for any other host communication. »

  However, even with a second NETWORK adapter the virtual machines cannot ping eachother when they are on a different esx host. When they are on the same host esx virtual machines can ping each other. Also, when they are on different hosts, so that a virtual machine cannot reach each other on their dedicated IP address, virtual machines can reach other when ping the second card NETWORK (the one without an informed gateway).

  For example, the next 2 guests are connected unicast:

  VM1 has 2 network cards, NIC1 = 172.18.18.41 with gateway (dedicated IP) and NIC2 = 172.18.18.43 without gateway / WLBS enabled.

  VM2 has 2 network cards, NIC1 = 172.18.18.42 with gateway (dedicated IP) and NIC2 = 172.18.18.44 without gateway / WLBS enabled.

  When on the same ESX host VM1 can reach VM2 on 172.18.18.42 and 172.18.18.44, and vice versa.

  When on ESX different hosts VM1 cannot reach VM2 on 172.18.18.42 but it can reach VM2 thanks 172.18.18.44. In this case VM2 cannot reach VM1 on 172.18.18.41 but can reach VM1 on 172.18.18.43.

  I followed and applied the settings recommended in this article: http://KB.VMware.com/selfservice/microsites/search.do?cmd=displayKC & docType = kc & externalId = 1556 & sliceId = 1 & docTypeID = DT_KB_1_1 & dialogID = 42912404 & StateID = 0% 200% 2041454115

  I even tried the kb from microsoft as shown here: http://support.Microsoft.com/kb/898867 even if the virtual machines have 2 network cards, but of course that did not help either.

  Does anyone have an idea what is happening here?

  The fact that it works on the same host, but not on different hosts type advanced to a network within VMware issue.

  Thanks in advance,

  Bram

  It seems that ir can be a problem of IP routing, even with the hosts on the same subnet.  Make sure that your routing table that traffic on each that is to/from your mgmt that ips turns off your local management interface.  If it isn't, then update your routing table in order to.

  Or, you could try setting up your mgmt network cards on a different subnet from your IP NLB.  I suspect that this will solve the problem.

• Two virtual machines to communicate with each other - intent an SMS Lab for test deployment?

  Hi friends ,.

  I am a new user and would like your help pretty desperately. The scenario is that I want to implement a SMS Lab to deploy the application from the server to a client and test the application. I have all the necessary knowledge to the packaging of application is concerned, and would like to help as much as VMWare is concerned.

  I created two virtual machines and one of them will be configured as a server and the other will be the client. I created a team with these two machines in it. I am trying to ping from one machine to the other and its does not work. I only use the method of configuration host. The idea is simply to make the two systems communicate so that I can finish the entire configuration and use the same SMS deployment lab.

  -First of all, I'm new to all this so I would like to know whther to everything I do is correct and what is the largest possible?

  -What I have to do something else to make sure that those two communicate about someother or any other configuration software is necessary?

  I would like to ask you guys to be a little more specific are you when you help others that I need you guys ore than a person who is used to working on VMWare.

  And just so you know if it helps, I use VMWare Workstation 6.0.

  What you are doing is reasonable.  Both of your virtual machines have an IP address on the same subnet?  In general, the scenarios no-ping, the first thing to check is the firewall in the guest computers.  Have you checked that allows ping traffic?  If it is disabled?

• Some virtual machines have intermittent network connectivity problems and rest work correctly.

• Two virtual machines share the same physical network adapter

  I have a virtual network adapter that I linked to a physical network adapter on my box where two virtual machines are running.

  I assigned two virtual machines to this vmnet adapter.

  On one I can ping other machines of physics on the same subnet as the physical computer, but the other VM can ping only other virtual machines.

  When I try to ping from one physical computer to this virtual machine I get the error message windows "ping transmission has failed. General failure. ».

  Is what I'm trying to are not not possible?

  First thing to do is to ensure the automatic bypass is enabled disabled in the VMnet virtual network editor your use to the bridge to.

  Second need to see the output of ipconfig/all on the Windows host and guests and or ifconfig on the Linux host and or guests.

  DO NOT copy and paste the output directly in the body of the response rather redirect the output of the commands in a text file and then archive (compress) files in a single zip archive and attach it to an answer.

  You can use the following example:

  Under Windows:

  ipconfig/all > "% USERPROFILE%\Desktop\host_ipconfig.txt".

  ipconfig/all > "%USERPROFILE%\Desktop\guest (n) _ipconfig.txt".

  Linux:

  ifconfig > ~/Desktop/host_ipconfig.txt

  ifconfig > ~/Desktop/guest (n) _ipconfig.txt

  Also include in the archive .zip .vmx and vmware*.log for two Virtual Machines configuration files.

• How to make a submission even as RDM for two Virtual Machines

  Hi I have a question.

  We have a server ESX4.0 with two Virtual Machines running on it. I presented a 100 GB of SAN storage to this particular ESX host, this storage space must be shared between two virtual machines as RDM.

  But when I add this storage on a computer virtual as RDM, it does not allow me to present the same storage another VM, of RDM is displayed under the name hidden. Is it possible to do so.

  Kind regards

  Khurram Shahzad

  This is only possible with the MSCS clustering functionality.  With the same logic unit or disc number to multiple hosts without clusting will damage the volume of data / as the new system will try to initialize the disk.

  Your RDM may also need to be in virtual compatibility mode to do this.

  The guide of vmware on clustering with MSCS and there should be information about it.

• can we run two virtual machines simultaneously on ESXi

  Hi all

  I created two virtual machines

  1 & gt; Windows2003

  2 & gt; Red Hat Linux 5

  but I'm not able to run two machines at the same time, when I try to turn on the second machine as the other machines it works throw me error saying "resource memory Admission Control failure".

  Second thing can we export machines, we have created?

  Thank you

  Carla

  You'll probably have to remove the virtual machine to add at least 600 MB - have you seen the instructions on post - http://communities.vmware.com/message/1026853#1026853.

• Network configuration for two virtual machines on a host

  I have two XP running on a Vista 64 host using 6.5 guests.  I would like to power instant message between the two guests.  I use the option open, and each guest can comminicate outward, very well.  However, if I send an instant message from one guest to another, the message can't.  All parameters in the virtual network editor are the default values on the two hosts.  Thank you.

  so IM between two virtual machines should work as well.

  There must be a factor that we haven't talked yet - any ideas?

• Two virtual machines running at the same time

  Fussion 1.0, I remember being able to use two virtual machines at the same time, and each me each own IP without worrying if I used the bridged network configuration or address NAT. With the Version 2.0.1 (128865), only one will get an IP address and the other, the two XP SP3, visit account disabled NETWORK card. Any recommendations?

  Yes, it's tru, but I updated the vmx file to have another MAC. NIC I get this error when I try to boot the secondary machine (which otherwise boots fine solo).

  As I mentioned in the linked post, there are several unique identifiers that MAC address. Fusion has a UUID, and Windows has a SID. All must be unique (my guess is that it's the SID).

  The network bridge on/dev/vmnet0 of the device does not work.

  Which will result in network bridge does not work. The only suggestion I have right now is to try to restart the host, but demand around other people seem to be seeing this as well.

• 2 virtual machines: 2003 & XP - networking

  Hello

  I would like to ask, how do I set the virtual network settings and network connections in two virtual machines.

  I have 2003, which is the DHCP and DNS, server in a virtual machine.

  And another one, XP, which is just a workstation.

  The two operating systems run in parallel in VMware Workstation.

  What should I do, to set up the Internet access (by host) on 2003 and XP connection for 2003?

  Should I use DHCP/NAT in the virtual network Editor?

  Thanks in advance

  If you want your virtual machine to Windows 2003 to provide DHCP, you will have to disable the VMWare DHCP server for the vmnet NAT.  (Or disable the DHCP service or the scope on your virtual machine Windows 2003).  But otherwise, NAT will work as long as any other machine on your LAN physical needs access to the virtual machine to Windows 2003.  If there is, then you'll want to bridged.  But then you'll want to disable any DHCP server that you have on your local network.  (Alternatively, disable the DHCP service or the scope on your virtual machine Windows 2003).
