  How to monitor the TX and RX on PERFORMANCE for virtual network adapter BASP monitor?

  I have a virtual network adapter that is created with Broadcom.

  This virtual interface named "BASP eCard" visible on the performance monitor in the category 'Rhythm Pipe' but not in the category "Network Interface".

  This is problematic because the Tx and Rx (bytes received/send in second) is available in "Network Interface" that show physical network cards only.

  Someone has an idea?

  Thank you

  This issue is beyond the scope of this site (for consumers) and to be sure, you get the best (and fastest) reply, we have to ask either on Technet (for IT Pro) or MSDN (for developers)

• Adding a virtual processor for a host ESX 4 UP1

  Hi - I built a SLES10SP3/OES2SP2 guest and now know that she could really benefit from a second processor.  Simply change the '1' to '2' is not recommended - not to mention that it does not add a processor according to the operating system.  I've seen several articles dealing with the change in the number of virtual processors, but none seems to be right on the target.  Seems more talk about reducing the number of processors, talking about the Windows VM, etc..

  Can someone tell me the correct procedure to follow - if it is still possible to do!  The physical server is a physical processor 1 HP ML350 G6 which indicates 4 x 2,266 GHz processors cores in the vSphere client.  8 logical processors. Xeon E5520.  I use vShere 4 Enterprise Plus.  The use of CPU resources as is currently around 10% used on the horizontal bar to 1143 MHz chart.  From time to time, it stings at 2400 MHz. The capacity is 4 x 2.266 GHz.

  There are 11 active VMs (SLES, 2003 and Netware) running in a pool with the default settings of the Pool.  There's a VMs additional 4 in the same pool currently shutdown.

  If it works, I want to do on 2003 server as well.

  FYI - I also built a SLES10SP2 server from scratch with 2 virtual processors and operating system takes advantage of them.

  Thank you vey,

  In general, you should try to work with as less as possible processors. However, you can add more, if you need.

  The VMware point of view that is easy, just change vCPU th enumber.

  Depending on the guest operating system and the kernel/HAL used, you need to change this one a multiprocessor.

• Slow performance with P410i need to hardware upgrade?

  Hello

  I saw this chapter on the release notes (http://www.vmware.com/support/vsphere4/doc/vsp_esx40_vc40_rel_notes.html):

  "Slow performance during virtual machine put under tension, or disk IO on ESX/ESXi on HP G6 P410i or controller Smart Array P410 of platform

  Some of these hosts can show slowed performance over the power of the VM on or by generating a disk i/o. The main symptom is degraded performance of e/s, causing a large number of error messages similar to the following to be recorded in the logs.

  Solution: install the HP upgrade of P-series 256 MB Cache module: http://h30094.www3.HP.com/product.asp?mfg_partno=462968-B21 & pagemode = ca & JumpID = in_r3924/KC "

  Has anyone encountered this problem? I would like to know if this problem appears with the disk i/o of the service console (in its vmdk files?).

  Kind regards.

  M.A.

  We recently bought a ML350 G6 with disks SAS 3 x 146GM 15 k and base Comptroller P410i.  I was appalled when deploying a VM from a 20 GB model took 7 hours and slowed down the other virtual machine running on the box to a crawl.  We have added the cache of 512 MB with the dough and the difference is like night and day.  Deploy from the same model now completes in less than 15 minutes.

• Virtual Center audit for virtual machines and ESX hosts

  Hi guys.

  I need to audit a system with 1000 + virtual PCs and hope you guys knew a script floating around in the VMware community who could interrogate Virtual Center for more information on all ESX and VMS hosts. Did anyone done something like this before?

  Looking for information on ESX, versions hostnames, Virtual Machines running on each host and the types of each virtual machine, the IP address of each virtual machine OS.

  Thoughts anyone?

  Thank you

• Best tolerance\failover of fault for two identical ESX 3.5 hosts

  Hi, I'm wondering what the best way to configure ESX3.5 on two physical hosts making it fault tolerant\mirrored or for the best technique for tipping...

  VM slices are on a data store on another server. I hope that this question is not too vague? Thank you

  If vSphere isn't an option, then (by definition of VMware) fault tolerance is not possible. With ESX 3.5, the only option of failover is HA (make sure that you have the VMware license which includes HA), which requires vcenter Server as well.

  Yes, DRS and HA can be activated at the same time.

  According to what the VMs system will do, I would recommend having at least 4 cards with 2 NICs by vSwitch network. In vSwitch0 I place the Service Console and VMotion VMkernel (VMkernel is required to connect to your NFS data warehouses) - all require unique IP addresses. In vSwitch1, I would create all groups of port VM (i.e. virtual local networks). According to future plans, performance requirements and others, I would personally use 6 cards per server, 2 by vSwitch and Service Console and VMotion in vSwitch0, VMkernel vSwitch1 and port VM groups in vSwitch2.

  If the plan is for 2 guests ESX 4 NETWORK ports in the NFS box should be fine.

• Slow network performance for non - vm with ESXi 4.0 machines

  I have ESXi 4.0 running on an IBM x 3850 M2 with 2 6-core Xeon, 64 GB RAM, 1.2 to SAS RAID 0 and 2 Gbit NIC connected to the 100 MB switch.  Two physical network cards is configured to use a vSwitch.  The management network use vmnic0 with vmnic1 as before.  The virtual computer network use vmnic1 with vmnic0 as before.

  I created a half-dozen VMs with VMware Tools installed, a certain Win XP, Win2003 Server.  Access to the network between the virtual machines is ok (_{270Mbits/s), but access to external guests is very slow (}2.5Mbits / s).  Here's the output of iperf, first between two virtual machines (tnealxpvm and rptkerbtest1), and then between a virtual machine and an external host (tnealxp03).  I guess the network access VM-on-VM is probably in memory and touch even the network hardware?

  Hello

  No reason to hardcode them guests at 100 Mbps.  Configure your guests to autodetect speed connection and duplex.  It's ok if your report speed/duplex of link guests that are different from your physical network.

  Try to configure your NIC Host (ESX) autodetect. Check that they autodetect to 100/Full.  Some older switches have problems with autodetecting link speed/duplex, but I prefer to configure NIC gear to detect automatically if possible.

• Possible for the host to read the files on virtual machines?

  Is it possible for a host read files on virtual machines?

  If you can get information using vmrun command, then I think that vmware-cmd command will help to define the variables that can think inside the vmx file. As vmx file is inside ESX server only so that you can shut down the VM and edit the vmx file, then you can register to the virtual machine using the vmware-cmd command.

  Thank you

• How to remove the host esx 3.5 virtual Center

  Can't find info on how to do to remove the host esx virtual center.

  How to do?

  THX.

  Right-click on your host in the left pane and click Disconnect and then once it is disconnected you can right click on the host again and click on Remove and which removes the host to vCenter.

• Trying to increase the capacity of virtual resource Flash, no host esx and no SSD is located

  In vSphere 5.5 WebClient, click host esx-> settings-> virtual Flash Resource Management.

  Then click on the button 'Add ability '. Empty the list of hosts/SSD devices.

  I followed the instructions with this announcement, but the list of hosts/SSD devices remains empty.

  https://communities.VMware.com/thread/464660

  Anyone know how to get around this problem? Thank you!

  It works indeed. You need to do some CLI commands to mark the device as a local and an SSD, but I outlined the steps in a post on my blog:

• DMZ Canals to allow the VM Update Manager 4.0 Update 1 for work FRO ESX 4.0 Hosts?

  Hi all.

  I'm trying to get two ESX 4.0 servers in the DMZ to be allow to get patched by our internal server VMupdate Manager... Having a few problems to work through our firewall and was hoping that someone who post the ports required to make this work? When I scan the host I get this error:

  Host cannot download Vmware Update Manager patch store files. Check your network connectivity and configuration of firewall and esxupdate logs for more details.

  ESX host connects to the Manager to update through port 80. The reverse proxy forwards the request to 9084.

  For host ESX sweeping and sanitation, Update Manager requires that port 80 be open on the ESX host.

• Setting up a virtual host Apache for Sites of the Complutense University of MADRID

  As the subject says: I am trying to configure virtual hosts with apache for the Sites of the Complutense University of MADRID. Now, we are trying to set up for each site of the Complutense University of MADRID, we have an ip address. Done on the browser when I see that someone typed in "http://www.myfirstsite.com" (through the magic of dns that they get routed to my server). Once they are at the level of the Apache Server I want to configure virtual hosts, so I can redirect the user to the appropriate site residing in the Complutense University of MADRID.
  
  Now, it is possible for me to access the sites by this "http://myservername/myfirstsite". But what I want Setup of Apache, is that when someone types in "http://www.myfirstsite.com" they see site whatever, I want them to see in the Complutense University of MADRID. But mann I just don't know what would be the document root or how could I go to get users to SEE what I want them to see. Can someone help me with this please? Thanks in advance.

  You should be able to stick with the default apache configuration where he will answer for any host name and create virtual servers for each instance with the root of the document appropriate for this instance of CS. Then you should be able to use rewrite rules to direct users to the virtual host appropriate depending on what URL they access the server with. See the documentation for Apache mod_rewrite around: http://httpd.apache.org/docs/current/rewrite/

• Adding more than one host ESX and the upgrade at the same time.  What is the order of preference of the operations here?

  We are budgeting for more licenses and hardware for 2014 and want to do immediately in January.  I am trying to decide what is the best order of operations for adding two vmware hosts additional to our current installation of vsphere and also upgrade our vsphere / esx 4.1 u3 for the latest and best.

  We have 3 Dell PowerEdge R710 running ESX 4.1 U3.  In this vmware cluster, there is a vcenter server 4.1 U3 virtual machine handle this.  The three servers are about 90% memory used so we add 2 additional servers.  Probably the Dell PowerEdge r.620 since we get up 2 in the space of a 710.  Storage is on a san EMC NX4 NFS which will become too but not yet, let's just deal with the vmware part.

  When adding additional r.620 2, should I install ESX 4.1 on them and join them to the existing cluster and THEN pass vcenter and each one esx?  I ask precisely because 90% of use on 3 current servers, I need 2 other servers to support the update operations take place.  They would be able to repel vmotioned vm while each host receives an upgrade at the same time.

  So which is the best way to go about adding of the hosts and the upgrade?  Would I add as 4.1, then they would be available as targets vmotion and so I have room to start the hosts one upgrade at a time?

  If I update vcenter to the latest version, it is comparable backwards and can manage the 4.1 hosts, but also hosts 5.x?  I guess version 5.5 is the last one I would get from VMWare?  It is right of ESXi, then, how is this ESX ESXi 5.5 4.1 upgrade?  How much storage space do I need for ESXi 5.5, as I'm dechatoiement out of these r.620 Dell and need to know what hard drive to put in.

  The steps that you must follow

  -Updated vCenter Server

  -Upgrade of the ESX hosts (because we do a updating of the material we will install 5.5 on our new guests and add them to the cluster and then dismantle our existing)

  -Upgrade VMWare tools

  -Update data warehouses

  ESXi 5.5 has these storage requirements:

  • Installing ESXi 5.5 requires a boot device is at least 1 GB in size. When booting from a local disk or SAN/LUN iSCSI, a 5.2 GB drive is necessary to allow for the creation of the VMFS volume and a scratch 4 GB partition on the boot device. If a smaller drive or logical unit number is used, the installation program attempts to allocate a region scratching on a separate local disk. If a local drive is not found, the scratch partition (/ scratch) is located on the disk virtual ESXi host, linked to the/tmp/scratch. You can reconfigure /scratch to use another drive or logical unit number. For best performance and memory optimization, VMware recommends that you leave no /scratch on the ESXi host ramdisk.
  • To reconfigure / scratch, see Configure the Scratch Partition of vSphere Client vSphere Installation and Installation Guide.
  • Because of the sensitivity of the I/O devices, USB and SD, the installation program does not create a partition scratch on these devices. Therefore, there is no tangible benefits to the use of the great features of USB/SD that ESXi uses only the first 1 GB. When installing on USB or SD, tent Setup devices to allocate a region scratching on a local disk or the data store. If no disk is local or data store, /scratch is placed on the virtual disk. You must reconfigure /scratch to use a persistent data store after the installation.
  • In Auto deploy facilities, Setup attempts to allocate a region scratching on a local disk or the data store. If no local disk or data store is found /scratch is placed on the virtual disk. You must reconfigure /scratch to use a persistent data store after the installation.
  • For environments that start from a San or use Auto Deploy, it is not necessary to assign a separate logical unit number for each ESXi host. You can co-locate areas scrape for several hosts ESXi on a single LUN. The number of hosts assigned to a single LUN must balance the size of the LUN and behavior I/O virtual machines.
