VMware is virtual machine software that provides a virtualized set of hardware (a video adapter, a network adapter, and hard disk adapters) to the guest operating system. VMware virtual machines become highly portable between computers, because every host looks nearly identical to the guest. In practice, a system administrator can pause operations on a virtual machine guest, move or copy that guest to another physical computer, and there resume execution exactly at the point of suspension. VMware's enterprise software hypervisors for servers, VMware ESX and VMware ESXi are bare-metal embedded Hypervisors that run directly on server hardware without requiring an additional underlying operating system.

I have only experienced connecting ESXI hosts and a storage server to a Fibre Channel Switch, which allows me to connect the hosts to the storage.  
But if I were to try and use ethernet with 10GBe switch for the hosts and storage, how do the host and storage "see" each other?
In the FC switch I just had to connec them using the zone and WWN.
Does 10GBe switch use TCP/IP?
If VMWare if I go to add storage, there is no option for IP address of a storage. Only iSCSI or FC.

hello Guys ...


How i can solve error message that display before login windows and access deny to login .

I am using vSphere Client 5.1.0

Hi,  I have just upgraded to VMware 6.5 U1 and the gui is driving me nuts!  I also have some compatibility issues with the SANs I have attached via iscsi.  Is there a way to have multiple default policies for Multipath, one for one SAN and one for another?  If so how do I do it in v6.5 web client or vcentre?

Many thanks

if your SAN replicates to a DR SAN at hardware level, e.g. everything, does this reduce the need to have backup software that also has a software level replication element (i.e. veeam), e.g is this duplicating the same feature of the SAN's built in replication facility, or does it offer benefits above and beyond?
I have the last two VM's to migrate to a new Host.

1. Is there anything I need to consider with moving the vCenter vm to a new host (Usin Veeam quick migration)

2. I plan to use Veeam copy to copy the Veeam server to the new host - then power-off the original, then power on the copy on the new host - is this plan OK?

I'm trying to make a backup with VMware VDP 6 to two VMs one with Exchange server and another with File server, but I'm getting this error: An error occurred while quiescing the the virtual machine.
The two servers have windows server 2016.

Thank you in advance.
This is a VMware server installed with MS Windows Server 2008 r2. This is also a backup restored VM server.  We booting up this server, and run the sysprep with OOBE and generalize option. After that, this server stuck at booting up with error message:

    Windows could not finish configuring the system. To attempt to resume configuration, restart the computer

After that, I see the "Setup is starting services", and subsequently rebooting and rebooting. I heard that there could be some corrupted registry keys that need to be removed. How can I get the system boots into windows successfully?

Thanks in advance.
We are looking to test vSphere 6.5 for evaluating some of the new features.  We are currently running 6.0 but do not want to upgrade the entire test bed.

The configuration as it stands now is

 ESXi 6.0 installed on four Super Micro Servers and three Dell Servers
ESXi1-ESXi3 (dell)
ESXi4-ESXi7 (sm)
NetApp SAN is providing the storage to all ESXi Servers.
EqualLogc SAN is providing the storage to the Dell Servers.
Nexus 48 Port 10g Switch.

Infrastructure is on  This includes:

vCenter Server
ESXi Servers 1-7
Domain Controller
Horizon View Connection
Nexus Switch
Pfsense router
We will move the Dell r610 to vSphere ESXi 6.5 and have a new cluster.

 The idea is to connect to use a zero client on and  connect to a Windows VM and from there, launch a Web Browser to connect to the 6.5 vCenter.

Is this doable?

Can you use one DC and have a vCenter 6.0 and vCenter 6.5 on the same network?
HI Citrix Experts

i have this issue


To be honest this is not the first time I make golden image
But this is the first time I have such an issue
In the old time, I got the same problem with XenApp 6.5  PVS 7.0 and I fixed it by applying windows update KB2550978  
Now with XenApp 7.12   PVS  7.11  I got the same issue but applying KB2550978 does not help
I am a little bit confused kindly advice .
-What hypervisor are you using?   Vmware vsphere 6.0.0, 4600944
-What version of PVS are you using (target device software version and PVS server version )    7.11
•      Your windows updates are applied before imaging    I did 100 % plus I applied KB2550978 in order to avoid such issue even before I install any Citrix software on the image
•      followed this install order for preparing master VM for imaging https://support.citrix.com/article/CTX131481    I did this step by step other images worked very well with these steps just this which I use windows server 2008 R2 failed
•      You may want to test with just the OS updates and the bare minimum software needed i.e hypervisor tools and target device software, but no extra software installed on the master before imaging (sometimes the issue can be caused by some applications/software on the master)   I do this all the time in any imaging just build the OS – VMware tools – windows updates – Citrix imaging …
Hello everyone,

We are overhauling our infrastructure and wanted to know some opinions on both of these SAN units. We are looking into the Netapp FAS2650 & Tegile T4100 IFA to house our VMs. Biggest concerns are how well both integrate and function with Veeam 9.5 and ESXi 6.5. Does anyone have major issues or gripes with either one of these? We are planning on using iSCSI for the protocol, but heard NFS is gaining popularity. Which is a better practice, still continue to use iSCSI or use NFS? Any benefits or cons of using one over the other? Here is a quick rundown of our proposed infrastructure:

2- ESXi 6.5 hosts (Cisco UCS C220 M5s)
~200 users
~25 Virtual Machines
Planning on using 2x Nexus 3524x for the server backbone (all 10Gig including SAN & hosts)

Would appreciate some opinions and recommendations.

Dear All

                I have upgraded esxi version from 5.5 to 6.5, and in the esxi i have a linux with 2 nic added, 2 are physical nic, and one of the nic is not attached to any network cable, after i turn on the linux, the 2nd nic has dhcp assigned, suppose if i added it correctly it will show no ip, any area i have configured wrong ? any help would be appreciated, thanks !

We have an old Dell PowerEdge 2850 server that we use in our DMZ for a FTP and Customer portal for our customers.  We had a 136GB RAID1 partition and 409GB RAID5 partition.  The server's OS was VMware ESXi 3.5 and it was hosting Server 2003 virtuals.  One for the FTP site and one for our Customer portal.  From what I gathered, one of the RAID1 drives and one of the RAID5 drives went down.  Don't know the cause.  After tinkering it for a while, I blew away the RAID1 partition and replaced the failed drive.  The only thing on it was ESXi.  The virtuals sat on the RAID5 partition.  I replaced the drive and rebuilt it within the server's BIOS.  When I reinstalled ESXi, it detected that the RAID5 partition was a vmfs partition.  I was able to log into VMware to try and add the partition to the storage array ESXi seen that it was a vmhba1:1:0 drive with 409GB capacity.  But, when I went to add it, I got the message "Unable to read partition information from this disk."  

Is there any way or any tool I can use to get the data off of this partition?  It is mission critical.  I don't know if it's a hardware issue or if VMware simply can't read it so I'm tagging both to this question.
When I want to create a new virtual machine I get the following error:  The portgroup for Network adapter 1, VM Network, could not be found. It has been assigned to VM Network.
I am trying to understand What Synthetic Full Backup backs up as data.
I thought it will create a full backup from storage and inject the incremental backup it has created the same day to the Full backup.

However looking at the Veeamone reporter, I see under Transferred (GB) column 48.13 GB,  it is less than the incremental one day before.

Any Veeam Expert to explain the report as shown in the screenshot below:

Thank you
How can i solve this problem?
At work it is all perfectly. At home I can't log in. It seems allright, but in stead of my workspace, I get a black screen en after a while the Error in the quenstion.

I have updated tot VMWare 4.7. My laptop has windows 10 home edition. The virtual location of my work is Windows 7 enterprice.

How can I log in the workspace?

Thanks for your answer.

I would like to disconnect a Host from a Cluster and wanted the correct steps to do this.  

1. I have an ESXi Host with 5 running VMs and need to disconnect the ESXi Host for testing purpose.
2. After disconnecting, where exactly should I  place it (since it will be operating as a separate Host with VMs running)
2. If I move the VMs to another ESXi Host in the current cluster; can I add these VMs back to the same ESXi Host who was disconnected.

Thank you.
I have the following issue; I updated a machine running three servers (PDC, BDC and RDS) from VMWare 5.5 tot 6.5. Update went okay; updated VMWare tools. Network uses VMXnet 3, so VMware tools updated the driver. After booting I needed to configure the network cards again (the Ip adres was gone, as was DNS settings, gateway etc.). Rebooted and everything seems fine. But clients since then have had issues where connecting to a share (shared through Group Policy) works, but after some time the system returns an error that the share is inaccecable because of failed authentication. I also use roaming profile settings; so the whole client gives error (desktop, setting etc. all become inavailable). When login in the shares are always correctly made. One exception being; i map the home directory through AD settings (user > profile) directly. This mapping doesn't work, without any clear error.

I checked a lot of things; a lot of error seemed to relate to group policy; so I reset the complete set; made several authorative restores; disconnected client from the domain, deleted local policy and added to domain again. Nothing helps structurally. So I'm hoping somebody can help point to the one thing I'm missing in this case.
Dear all

                 I have a esxi test lab at home, just changed this mainboard "ASUS p7H55", after installed esxi 6.5, I can not detect the onboard nic card, and below is the nic model, but the other physical nic card I installed in the mainboard can detected, it is in intel nic, any idea how can I detect the onboard nic working ? any help would be appreciated, thanks !

Ok, so i have done V2V migration using Veeam Quick Migration / Veeam resotre.
no matter, what i do i get the attached error.
can anyone shed any light on this, is it something to do with Vmware version or incoparible H/w
i have tried :
1. sfc /scannow
2. chkdsk
Hello, I took over management of a HP ProLiant DL580 Gen8 hypervisor running VMWare. One of the hot-swappable hard drive lights gave an error so we purchased a new one, and swapped it out. After doing that, the system locked up, so we had to re-boot the hypervisor.

Then, the new hard drive would not sync, and continues to give a flashing amber light. Just to make sure it was not a bad hard drive we tried a 2nd one, with the same results.

How do I go about troubleshooting what is the problem with this hard drive not syncing?

Thank you,
I have a Linux server that is constantly maxing out CPU usage on my daily SolarWinds monitoring report. I checked the box out and it is part of our network team. They call it a "Radius/Tacacs and NAC. Networking asked me if I could just simply add my CPUs, so I checked out the configuration and it is configured with 6 virtual sockets all single core.
I doubt it is as simple as just adding CPUs. If I had set up this server I would have probably done 2 slots/2 core per slot, but that is only because that is how I have seen other virtual Linux boxes configured in the past. Can someone give me some suggestions and how I can prevent CPU from maxing out on this device? I know this is kind of vague but any trouble shooting suggestions would be welcome. Also does adding CPUs affect licensing?
Hi All,

I'm in the process of migrating an old file server to a new file server.  They both sit on the same SAN volume and are both thin provisioned.

I though as the data moved across it would release the space.  But this doesn't seem to be the case.

Is there a way to release unused thin provisioned space?

Many thanks
Using vSphere 5.5, with 3 esxi .
in Esxi1, i have a VM stored in a synology nas, called Unitrends. Yesterday, after the NAS had a power shortage, when i tried to restart the machine (without knowing at the time that the storage was not available), the name changed to /vmfx/volumes/530773a-4e463....... (inaccessible).
I powered back on the Synology NAS, and checked that the All Path Down error messages are cleared, and can browse the datastore. Still, i don't know how to rename this back to it's original name, and power on the machine...

Background Information:

- We have two separate but identical sites (Production and Disaster Recovery)
- Both sites will have their own infrastructure of 3x servers, 2x iSCSI switches, and 1x SAN
- Data from production site will be replicated to DR site quite regularly (may be real-time)
- Sites utilize VMware ESXi/vSphere 6.5 and will have Acceleration Kits

We are in the process of an infrastructure upgrade, and am in the planning phase of implementation.  Once we have all of the above fully implemented, how can I configure a proper fail over and fail back configuration?  I am pretty sure I may be able to configure High Availability on a single site for a failure of a single host; would it be possible to configure some type of fail over should a disaster completely bring down an entire site (if building hosting production equipment burns down)?

Is it even possible to utilize VMware High Availability to fail over to another site/SAN?  If it was a temporary failover (power at production site is lost, then comes back), would there be an automatic fail back?

Can I use this method to temporarily take down a site for maintenance while having no impact to end users?

Thank you in advance for any assistance provided.
