• Basic QS:-a virtual machine can share the memory of the 2 hosts?

  Hello

  I am very new to VMWare ESX, but looking at the docs, it seems that there is a possibility to create pools of resources by consolidating physical ESX Server hardware.

  However, it is not clear if a SINGLE virtual machine can run on multiple physical hosts?

  I have 2 physical servers:-each with 4 GB of RAM in a single pool of resources.

  Can I then run a virtual machine and assign it 8 GB? (and actually use up to 7 GB?)

  I'm güssing it is not possible to do...

  No, a guest can run on two physical hosts at the same time. It cannot use the resources provided by an ESX host.

  Resource with Betclic let you group all the resources of all ESX servers with this pool.

  Let's say you have two ESX servers with 3.6 GHz each. So your pool has 7.2 GHz available for its guests in this pool. However, this isn't a contignous resource, it is cut in two on two ESX hosts.

  Also, if you can, do not use resource pools. He must know exactly what you're doing, and it is a good source to make worse things running.

  The best resource on hand programmer is ESX itself. If you have a license to DRS use. According to our experience, it is very good by spreading the load on your ESX farm. If you want to set restrictions to the guests I would level comments.

• 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!

• 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.

• 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.

• 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?

• back-to-back connection between two virtual machines on different ESXi servers

  Assume that a name of Virtual Machine VM1 is on ESXi Server 1 and Virtual Machine name is VM2 exist on ESXi Server 2.

  We can configure two Virtual Machines back to back as connect us two physical machine back to back via cross cable. is this possible?

  Sorry for typo's fault, should be separated vswitch, with dedicated physical network card adapter

• 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

• Multiple virtual machines can share a common hard

  I just confirmed that multiple virtual machines can share a hard if they all see it as non-permanent, which is great if you want to experiment with different linux packages at the same time.

  Except the hard. REDO_ * files that are produced by a virtual machine are removed when you turn it off, and all the work is lost.

  Any ideas how I could prevent the hard. REDO_ * files deleted?

  the non-persistent flag is to capture instant temporary vmdk is ignored when the virtual machine is turned off.

  The vmdk. REDO_ file is actually a type of snapshot. If you want to avoid that it gets deleted turned off the power, you must use a regular snapshot - but then your sharing of this vmdk with other virtual machines will no longer work.

  For your scenario of I don't know one solution stable AND well other than the use of network shares.

  There is a hack to really share VMDK between two virtual machines, but is more stable.

  Another solution may be that share this drive via iSCSI acrooss your machines virtual more.

  Some time ago I tried to interrupt the process of vmware-vmx.exe seconds before turning off the virtual machine and then copy the REDO far so that I can use it again... but if I remember right the next time that you start the virtual computer will be created a new REDO log and it is so pretty useless :-(

• 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 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.

• 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.

• 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.

• Open a virtual machine in a san on 2 different esx hosts

  Hi, I have a Vsphere essentials, 2 Esx hosts and an Iscsi san, I need to connect the virtual machine in the two esx hosts (I know I don't have FT and HA), in order to launch the virtual machine never the first Esx and if first host, does not have the virtual machine on the second esx.

  I tryied to connect the virtual machine to the second host, but the Vsphere client tell me that's not possible, because the virtual machine is already present at the first ESX.

  There is a way to establish this setting?

  For some it may depend on your application, if you can run multiple instances of the same application? If it is a web application? It stores its data in files on the server, or it stores it in a database locally? or remote database?

  -VM on a local storage of the army, would not really recommended if you need so that it starts the VMS on host b quickly.

  -If the two hosts have access to permits it storage even say and what the application can really be run only once.  He could only save it to HostA and if it fails at some point that it will be released the lock, have it on the virtual machine and you will be able to manually register the virtual machine to host b and start the virtual machine.  However, you will not be able to really get ahead.

  -HA out of here, as if a host or power failure shuts on HostA, HostB will feed into the virtual machine down automatically

  -FT - here in the spectrum creates a VM ghost on the secondary host in levels (what happends on HostA happens on host b)

  -Another option to the other end of things has implemented Microsoft MSCS Clustering with iSCSI support I think.  You can run VMS with iSCSI to your San and clustered like this application.  Just note that with iscsi client it uses some CPU to create iscsi packets.

  -Web Cluster, Cluster database.    It doesn't matter if one of the nodes of web servers or the database nodes go down really that the user will be redirected to another node in the cluster so really no need for HA/FT.

  Of course, with some of the here above are expenses and pro / con of and there's a few ways to increase availability.

  The error message "no more virtual tiles can be allocated" appears when I try to use the effects in the quick edit mode in my 13 elements. The OK wand has to press several times for loading all effects models. The error returns when you select the particular model.

  The problem does not appear, if PH 13 items is run in administrator mode.

  The available computer resources are rather big enough: INTEL CPU i7 4 cores, 16 GB RAM, 1 TB HDD + 32 GB SSD, Windows 8.1.

  Please, advice how to fix this problem? Perhaps, there is patch or update available?

  I had this problem with some of the choices menu in PSE13 when my drive to work was only a SSD with 53 GB of free space. I assigned a second disc of work (my data disc with ~ 2 TB of free space) and the error disappeared.
