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.

what replication options are available for an Oracle DB running on windows server?
Does VMware SRM work for this or Xerto
Or which is best product to enable a seamless fail over and fail back?
Currently we are running on physical servers but these are due for replacement so need to decide whether to continue on physical or virtualize

I need to upgrade 2 Domain Controllers from Windows Server 2012 (not R2) to 2016. They are both in VM. I have a PDC and 1 that is replicating.
What is the best method to do the upgrade for both servers?
From what I am reading, the vmware version is a factor in getting the DC's upgraded to 2016.
Does this mean I need to upgrade to server 2012 R2 first, then upgrade the vmware version, then upgrade to 2016?

If keeping the same hardware and storage is my only option, what is the best path to get my DC's to 2016?

The environment is vCenter 6.5 update 2 with 4 vSphere 6.5 hosts.  We noticed our SQL cluster was complaining of clock skew every now and then, but it never lasted more than a second or two.  Yesterday it appears one of these events was in progress the moment I initiated a CPU migration on one of the VMs. SQL recorded up to two minutes difference with the DC on a different host. (also the authoritative time source)  Obviously the cluster was very insulted by this and went into fits.  It took about five minutes for the dust to settle and fortunately there was no damage.
Investigating a bit I found that when I moved a different VM onto the host with the DC, I could instantly create a skew of 30 seconds that would gradually correct itself over the next 40 seconds or so.
First I need a recommendation for a tool to that will record the time clock of multiple servers.  ws32tm seems to only talk to a DC. ( I did not know that till now!) And I need to be able to match this up to the host clocks also.
I am pretty sure I have the hosts and guests following vmware best practices for clock settings and sync, but suggestions are always welcome.  
Once I can quantify the problem, I will be bringing it to vmware support.  (ticket is already open, but they have not responded yet.)
Thanks Experts.

We have vCenter 6.5 installed on server 2012. We planned to go to 6.7 VCSA. However, the 2012 VM restarted and now vcenter web client doesnt come back up.  We get the following:


503 Service Unavailable (Failed to connect to endpoint: [class Vmacore::Http::LocalServiceSpec:0x000000deb87e6ca0] _serverNamespace = /vsphere-client action = Allow _port = 9090)

The problem we have is that there are still hosts that have 5.5 that had not been upgraded along with some distributed switches on older version that had not been updated.  What should be the route to restore access to 6.5 so we can upgrade hosts and vDS then move to 6.7 VCSA?

Hi All,

Do we have any script for cold migration of multiple vm from one cluster to another.

I have an IBM 3560 M3 server and wanted to know if I could dual/triple boot OS's? basically creating a bootloader for each separate hard drive. I would have hyper-v, vmware, zen etc on their own separate hard drives.

Data Protection Manager 1801 fails to create a replica for VMware 6.5 virtual machines
I'm using a disk as my storage pool.
The virtual machines are running Ubuntu 16.04.4 LTS
I have reset the cbt files for individual virtual machines already.



It fails with an error; DPM encountered error from VMware Disk Subsystem  Server x.x.x.x Error code 14009 (ID 33620 Details internal error code: 0x80990EF1)

Hi All

We currently run VMware 5.5 over two sites, one for production and one for recovery (managed by site recovery). We also use VDP. We are currently running 5 older servers (HP G5), 1 * management and 4* hosts running VMware 5.5.

we are about to purchase 5 new replacement servers and upgrade to VMware 6.5. What is the best way to accomplish this? I have been told that it is best to upgrade the vcenter server to 6.5 first. Is this possible on the G5, or would it be better to install  a new vcenter server on the new equipment? We will then need to failover one of the existing vms on a physical host to introduce a new one into the environment, is this correct? Any advice on the best way to approach this and avoid any pitfalls would be great.

Thankyou,
Paul

I have a Windows server 2008 R2 File server which name is serverA working on DELL poweredge R720.

Because the file server always fails to apply update, so I want to convert it to Virtual Machine and open it in VMWare Workstation, so that I can test and find the reason.

The VMWare workstation version is 14 and works on a Windows 7 Pro host computer.

I found the way is convert to VHD, then convert VHD to VMDK, but while I add VMDK into new VM, the VM cannot boot up.

Error message is A disk read error occurred.

what's the proper way to convert physical Windows Server 2008 R2 into VMWare Workstation virtual machine?

Thank you for any suggestion.

Had to reboot a ESXi 5.5 server.  It decided that it wanted to pull an DHCP ipv4 address.  When trying to set it back to static. it tosses out an error that it cant save it because of iPv6.  We have that disabled.  It can pull a DHCP address no issue.  Never seen this before.  Where do i start?

hi guys
i have a very confusing problem that caught and get me crazy. please and please anyone help me

i have a Asterisk base PBX VM (Issabel 4) and a SIP Trunk Line that connect to a modem.
my modem IP is "10.192.6.25/30" and i connect that directly to an ESXi server and attached that to a VM(my PBX)
my PBX IP is "10.192.6.26/30"
when i setup entire system  i had no problem and system goes very well but after 1 or 2 day my SIP TRUNK calls suddenly lost and every body's call has been terminate!!
i have other connection via a sangoma Vega50 External Gateway(for my analog telephone lines) and it's work very well ... i mean i'm pretty sure my PBX does not have a problem but when i ping my SIP TRUNK's modem in a period time like 24 hours , i see errors like this :

hello all

after some machine's boot ( and possibly also from time to time ), i receive email related to the operation of vmware service.
email is sent by the guest machines to the local root user with no subject.
the vmware service is (open) vmtoolsd 10.0.7.52125 (build-3227872) packaged with ubuntu xenial.
the hosts are esx6.

i'd like to know what the hell sends those email and how to disable them

here is an example of the most frequent email received ( apparently the same content as /var/log/vmware-vmsvc.log )

VM Information on Edit Settings

On the Edit Settings of the VM, I see:
VM disk  is Thin Provisioned , provisioned size : 60GB  ---Maximum Size : 300 GB
 so the VM disk will fill up till it reaches 300GB , if that space is available on the Datastore.


** let 's say Datastore has 200 GB
 if they set up Maximum Size to 300 GB, will VMware system warn the Administrator that the Datastore the VM is on does  not have that  much space ? or they can put any number on the Maximum Size field, and Vmware system will not care ?

Thanks

Good afternoon,

 I am currently trying to migrate and update my vcenter 5.5 to VCSA 6.5.

 When executing the migration wizard, it indicates the following error (See image). Validating the logs, does not indicate more information.

 I would like to validate if you have seen the error and the possible solution.

 I am running the installer from another Windows server, which are in the same VLAN of the vCenter and in the same ip range.

 I remain attentive to your answers.

I'm using VSphere ESXi 6.0 U2 for a home lab and after editing my .vmx file to allow for iMessage use (following this guide) on a macOS High Sierra VM, the file type is simply recognized as "file" and not "Virtual Machine". My edits consist of:


deleting this line:

ethernet0.addressType = "generated"


and adding these lines:

Im trying to setup a windows 2016 server on vultr with my own iso and license key

I have to use this guide
https://www.vultr.com/docs/windows-custom-iso-with-virtio-drivers

However, instead of a fresh install, I want to image one of the physical Dev servers and use this to quickly get going

Do you think it will be possible, and what would I need to do?

Hello there. In a couple of days we will be migrating a small business with a single 2012R2 Server/DC in VMware to a new server box hosting 2016 Standard, and we'll be creating a new HyperV DC using one of the licences that come with 2016 Standard Ed. I'm wondering about what specific settings I should use for creating a Hyper-V server that will function as everything (DC and all roles). To clarify, I'm not going to migrate the VMware VHD file to Hyper-V, but instead migrate the data over and create a new Hyper-V, as if they were both physical boxes.

So my questions are:
1. What are the ideal Hyper-V settings (generation 1 vs 2, secure boot, etc) for this server configuration?
2. Even though 2016 Stnd comes with 2 Hyper-V licences, will it let me create the Hyper-V without the installation media (or do I still need to download a 2016 Stnd ISO?
3. Anything else I should know as someone unfamiliar with hyper-V in general? I want the transition to be as smooth as possible.

hi,

adfs1 server => active directory federation service started properly

adfs2 server => active directory federation service unable to start

During my standby today, ADFS2 server seem there is a improper shutdown and the roles are ADDS, ADFS, DNS, FS, IIS, NAP.

Encountered some error and explain how incident happened as follow:

ADFS service unable to start at ADFS Server 2. Should be started for this adfs2 server? As the adfs service is already started in adfs1 server is consider (primary active server) and adfs2 server is consider (secondary standby sever) from mt own checking but these servers are not configured by me. When adfs1 is down then should failover to adfs2 but there is no failover cluster in ADFS1 & ADFS2?

Currently, SAP is down and IBM/App team are checking now. Not sure this will be escalated back to the server team as i need to troubleshoot whether cause by ADFS or other issues for now. ps advice me clearly with the steps as i am not very familiar what need to check or ask so far.


Q1: Should adfs2 should be started as trying to start it but with error.
adfs_Issue.jpgQ2: how to troubelshoot the paging files issue
paging_issue.jpgQ3: how to troubleshoot the shutdown issue whether is caused by VMware,  Guest OS level, Vdisk on LUN storage or SAP Application
