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.

This is something I should have been able to figure out but it is escaping me at the moment :

when I run this file I get the following output in the     @{n = 'Guest Service Interface Status'; e = {$GuestSvcStatus}}, section

Guest Service Interface Status : {True, True, True, True}

Can someone please show me where the error is.

Thanks,

Hello,

I'm facing a problem when lanching a new openstack instance it shows me this error message:

Error: Failed to perform requested operation on instance "ub15_flavor", the instance has an error status: Please try again later [Error: Exceeded maximum number of retries. Exhausted all hosts available for retrying build failures for instance f2b706fc-2619-4f15-8c07-5c216b4cc336.].

Note: I'm using Centos 7 - Openstack queens in Vmware workstation.
I have tried with cirros minimal (512M Ram) and tried also with Centos and Ubuntu.

Hi

We use VMware and VEEAM backup. Due to some database corruption on our Windows 2008 Exchange 2007 server, I am planning to run Eseutil /P and Eseutil /D on the server during this weekend.

The total size of the Mailbox database on the exchange is 365 GB and is hosted on D: Drive and the available free space on this drive is 800GB. I am planning to take a Snapshot or Clone the Exchange server before I run these Eseutil utilities.

After running these utilities, in case the database get into a problem and if data loss occurs, I can bring up the Cloned server OR the Snapshot.

In my situation please let me know what would be the best CLONING or SNASPHOT?
Any suggesting would be great!
Thanks in advance

Greetings,

We deleted a VM folder on a datastore but don't see the space the VM was taking up reflected in the free space of the datastore. The VM folder held a out-of-production VM that had not been used since 2016. It was 4TB. It may or may not have been removed from inventory back then. When deleting the files, delete from disk was chosen. The VM storage was not thin provisioned. It is iSCSI to an EMC 3250 SAN.

How can we reclaim the 4TB of storage?

Thanks a lot

This article is divided into two sections. 1) First describes how you can connect to server / service / device with Username and secure password in powershell. 2) Second part is to use secure credentials and connect to vCenters which are in Linked Mode or isolated environment.

Greetings,
I have an EMC VNXe 3150. I also have (3) ESXi 5.5 hosts in a datacenter. I have a few datastores over 2TB. However, I am unable to add a 2.5TB datastore from a LUN of 2.5TB presented to the hosts over iSCSI, just like all of the others. It is GPT, VMFS-5, 1MB. The stand-alone client shows 2TB max file size though. Error simply says an error occurred during host config.

Any help is much appreciated.

I am using ESXi 6 Update on all of our 110 VMware which is manged by  a vCenter 6 Update 3 vCenter server. Out mangement network is on and IP of 10.60.22.2 but we want to place our vmotioned traffic on 192.168.2.3. So I need to create a new gateway.  I did create a new TCP stack via the cli but was not able to edit it in the GUI once create. What is the best way to create a second gateway IP for my vmotion network

ESX host is greyed out in vCenter.  I recently lost some volumes from SAN storage.  After recreating the volumes and restoring vm's from backup , I can no longer connect to the host.  The vm's within the host are still available and online but not accessible through vCenter or vSphere client.  I am unable to connect to the console to restart the management interfaces.

We have a number of Windows Server (2008 R2 upwards) which store sensitive, shared data and we are looking to encrypt it. The Windows servers are currently running as VMware virtual machines all of which reside on a SAN.

I initially thought the simplest solution would be to enable BitLocker to encrypt the entire disk, but apparently there is an issue using BitLocker with virtual machines (due to limitations of TPM/BIOS) - is this accurate?

If BitLocker can't be used, what are the alternatives? As the data on the server is shared by many people in the business, I didn't think EFS could be used as that's encrypted using a particular persons account?

Hi Guys

I have a new Dell PowerEdge R430 server that is configured with ESXi 6.0. The server is RAID 5 configured and it has a single vmfs datastore set up.  It currently hosts 12 VMs with an average of 4 running at any one time.  The server is standalone, so is not part of a vSphere environment, it is managed through the VMware Host client.

We have been experiencing unexpected reboots of the server.  The ESXi logs haven't helped up to now as they were being stored in a ramdisk so getting lost after each reboot.  I have now reconfigured the logs to write to a scratch folder.

I am now keen to get OpenManage Server Administrator installed so I can see exactly what is going on on this server.  My question is, can I set this up in a standalone environment like I have, the documentation doesnt seem to mention installing through the VMware Host client, I assume it should just be the same, upload to the datastore and run the installer via SSH ??

How do I then view the OMSA ?  Is there a client I need to install on my laptop ?

Thanks
Matthew

ESXI 6.5

When I try to add a new iSCSI adapter for my new SQL Cluster servers
I highlight the Host  select configure tab then select storage adapters hit the GREEN Plus + sign select "software iSCSI adapter"
It fails with an error occurred during host configuration operation failed diagnostics report module iSCSI_vmk not loaded
I have 5 ESXI hosts and on three it works but on the two I need it does not

From the vmkernal log on both ESXI hosts it fails I get the same message.

This is Host 1

This is the first time I  added the iSCSI Adapters to these to hosts

How can it be already exists?
 

Any ideas?

Thank you

I cannot convert XP desktop using VMware vCenter converter standalone on Win 10 desktop. I am using IP addresses for the shares, permission to the shares and folders are full for everyone, passwords works fine.
XP is not on the domain, but Win 10 is. When I am starting the conversion task, I am getting Certificate warnings and fails at the end with status Unable to obtain the lock on virtual disks.

Thank you all in advance.

I have 10 Vmware ESXi, hosts and I am only seeing this issue on one of them

In the process of doing an in place upgrade from Vmware ESXi 6.5 to Vmware 6.5 U1.
on all hosts, which is all dell hardware, I have used the Virtual DVD option in the DRAC to load the iso.
The installed launches ever time without any issues.
On one host the installer does not find the existing install to upgrade, it just find volumes with VMFS partitions that will be over written. If I select the parition or disk where Vmare is installed, it treats it like a new install.
On all the other hosts, it recognized it as an install and ran the upgrade from 6.5 to 6.5 U1.
any ideas?
On all host of the 9 that went without issues, 8 are running Vmware from Dual SD cards. The host in questions has dual SD cards as well.

Any ideas why on this one host, the install is not seeing the current install?

Hi

We have an exchange 2007 server with C and D drive
On C: drive the total size is 88.2 GB and the free space 10.3GB

On D: the exchange mailbox database is hosted and the total space on this drive was: 612GB
Used is: 475 GB
Free is: 137GB

We use VMware I accidently increased the space on D drive to another 700GB and after rescanning the discs on the VMs disk management, I extended the disk and added the unallocated space.

Now it is showing 1.3680742TB as shown in the attached snapshot. I would like have a total size of 800GB  on the D:
Please let me know if these is a way of doing this.
Thanks any help will be great.

I have a poweredge VRTX. The chassis is set to use NTP and London Timezone. I connect to the vsphere 6.5 blades via ip_address in a web browser. The are set to use NTP also.The esxi blades can only show UTC time, the are an hour behind.
Is this a time mismatch that could be an issue with certificates ?
Does this mean an issue with NTP ?

Hi

We are using Exchange 2007 and Event ID 474 and 705 is occurring and the server goes offline  and I have to restart the information store when this event happens. I posted in the forums and I have been told either to do repair the database by using the eseutil/P , eseutil/D, isentig-fix OR to create a new database and migrate all the mailboxes to a new database.
So I would like to create new database and migrate all the mailboxes to a new database. On my exchange I have D drive where the corrupted database is located.

The path is D:\ExchangeDB\Mailbox Database.edb
The current drive size is 700GB

We use VMware, Is it ok to create a new database on the same D:
OR do I need to create a separate Drive and then to create a new database on this drive?
Please suggest.

Our Vmware environment considt of a Windows based vCenter 6 update 3 server and 110 ESXi 6 update 2 hosts. We are in the process of redesigning out network and want to  finally break out our vmotion network into its own vlan. The blades nic layout would look like below. I have read the having vmotion across vlans / subnets is not supported due to the risk of latency. Yet I have see other KB article stating you can do it yet it is not recommended Thoughts?

vmnic0 - mgmt
vmnic1 - mgmt
vmnic2 - vmotion
vmnic3 - vmotion
vmnic4 - guest traffic
vmnic5  -guest traffic

I need to increase the size of this datastore on an VNX 3500 presented to 3 esxi hosts. Do I simply type 6 in place of the 4 by VMware (VMFS) Size? I haven't worked with EMC in a few years and don't want to mess with this in production in case I am incorrect. If that is correct, I will go to the hosts and rescan then increase.

Thanks a lot.

Dear Experts

We are looking for backup and remote replication to achieve the  business continuity and disaster recovery at present we have server with vmware hypervisor we have vmware essential plus Vm running application server, understood from expert exchange expert we can achieve it though vmware essential plus, also we got proposal from the Quest BACKUP AND DISASTER RECOVERY SUITE- Rapid Recovery Soultion,  with Rapid Recovery solution, we can do following below given features:- Bare Metal Recoveries, Rel-Time Backup, Zero Backup Window, Near Zero RPO, virtual stand-By-Hosts, Compression, Dedupe and Encryption, Replication and DR .
would like to understand the difference between VMware disaster solution and Quest BACKUP AND DISASTER RECOVERY SUITE, if we go for vmware does it require vmware license at the recover site also in additional to primary site license, looking for cost effective solution please suggest .

IE 11 gives either "cannot open web page" or "Can not open search page".  Chrome works fine.

We are using Server 2008 R2 Enterprise. We recently moved a server from one VMware storage to another. We also took off the network card and put it back on. The ip address did not change. Also other programs can't access their services such as Malwarebytes can't do updates, teamviewer can't connect and one or two others. I get the feeling it is a network issue that is affecting several programs IE 11 being the most obvious symptom


So far I have:
-reregistered ie11 dlls
-flushed DNS
-changed to dhcp with reservation
-reset all advance ie settings
-disabled addons
