From the Deployment and Configuration Guide vCenter Operations Manager 5
vCenter Operations Manager is a vApp that you import and deploy with a vCenter Server system.
So you will need to connect with your vSphere Client to a vCenter and then deploy the OVA to that environment.

Here is what I did to install vCli from scratch (tested with CentOS 6.3) :
yum install perl-Archive-Zip perl-Class-MethodMaker perl-SOAP-Lite perl-libxml-perl perl-XML-SAX perl-Archive-Zip perl-Class-MethodMaker perl-SOAP-Lite
Then I needed EPEL repository to install perl-Data-Dump with yum :

I tried perl-Data-UUID but it ...

You need the VMware Essentials Plus package or greater to leverage vMotion capabilities.
This is outlined in the VMware Editions comparison table.
With two hosts and no SAN, you can still perform a "shared-nothing" vMotion between the hosts, but it's only for a scheduled move. If a system fails completely, the VMs residing on the local storage would go ...

With beacon probing is is recommended to use at least 3 pNICs because that is the way the beacon works best. ESXi sends out a broadcast packet out of the physical NIC cards. The other pNICs within the same vSwitch then wait to see if they receive the packets from the other pNICs. Whichever pNIC doesn't receive the broadcast, ESXi then assumes it is a down ...

If you move to SPICE, it supports multiple monitors natively. Seeing how you are planning on using Fedora (in production?! wow...) you might want to try oVirt and build your openstack environment (if you really must have openstack for some reason) on oVirt.
Generally speaking oVirt/RHEV are built with VDI in mind, hence the included self service portals ...

Regarding the serial ports - seriously consider using an ethernet serial server, such as the DigiBoard port server TS series. You can install the drivers into the VM guest OS, and put the serial server anyplace on your network.
Alternatively, you can connect a VM guest to the physical ports on the ESXi server.

You certainly can have the VM migrated to ESXi, this would be rather easy.
Windows 2000 terminal services indeed did not support com port redirection via virtual circuits, but you might try to mimic this functionality through one of the freely available com port redirector software packages. If you do not have a Windows 2000 Server but only a Professional ...

It's possible... but probably not the type of thing that would go undetected. Most whole-VM backup solutions leverage temporary snapshots. This is the type of thing that will show up in the virtual machine's Tasks & Events log.
It sounds as though you're skeptical about what your outside consultant is actually doing. I'm not sure if there's a technical ...

Not sure why you got down-voted already but this question does look like "asked and answered" to me. The key phrase is "low-impact personal use".
Generally you gain little if anything by placing the OS on an SSD. Server OSes are a lot less "chatty" than desktop OSes, so there's a lot less disk I/O going on. Ordinarily you would put database transaction ...

For the disks themselves, you'll have use fdisk and increase the size of the partitions. After that you'll have to expand the filesystem that reside on it.
For an extension to a disk containing only vg stuff, you'll have to extend the pv, then extend the vg, then extend the selected lv and then expand the filesystem.

FYI, if all you need is basic control from OSX, check out Orbit-VM at https://code.google.com/p/orbit-vm/
It's aim is to provide an open source, cross-platform GUI for managing vSphere 4 servers.
However, I use this to manange my ESXi 5 box and it works great on Mountain Lion!

I have the same problem on a new ESXi 5.1 install. System has 12GB RAM. Under Configuration, Memory, Physical it shows 12068MB. But on Resource Allocation tab it shows Available Capacity 9325MB.
That's before I've even created any VMs. Where's the 3GB gone?

Plug the disks in and do whatever you need to in your BIOS/RAID controller to provision them. Consult the manual of your server if you're unsure of what this means.
Then rescan for storage within ESXi and add the discovered storage as a datastore. It is non-destructive.

I was able to figure this out with a lot of on the phone time with Wonderware. Basically inside each App Engine deployed to the Galaxy there is a configurable parameter called the "Checkpoint Period."
The Checkpoint Period is the period of time between when Archestra will write the current state (values, variables, etc...) of the application to disk. It ...

I never resolved this question but I was able to reproduce this graph signature on a few other hosts running ESXi 4.X. The solution was invariably to upgrade to ESXi 5.0+.

I agree with Nathan that this looks like a buffer filling on the receiver. You could confirm this with a packet capture, look for the receiver returning "TCP Zero Window". This is the receiver saying "stop, you're sending me too much!"
Another possible cause could be TCP Segmentation offload (TSO) on the sender. These old e1000 cards only had 64k buffers to ...

Upgrade vCenter first... A newer vCenter can typically see and connect to older ESX/ESXi hosts. You should be at version 5.1 at this time.
Do your virtual machines live on shared-storage? If so, you can disconnect them from the old cluster and add to the new... That's one option. Another is to join everything and migrate between.
Do you intend to continue ...

You're not really upgrading your hosts, you're replacing your hosts. The first step is always to upgrade your vCenter server first.

I'd do some basic network troubleshooting before returning to the applications that are driving you to distraction.
Do the arp tables make sense? Are there any routes on any of the systems? Are there firewall rules active? Can you verify which interface the management tools (web) are binding to?

You can safely add another vCPU. Upon boot, Windows will upgrade the HAL from Uniprocessor to Mutliprocessor.

You should generally be fine adding a virtual CPU to this configuration to ease contention issues. You don't mention your hardware configuration or the other guest virtual machines using resources on the host, though.
Do you have that visibility?
I would not mess with reservations at this juncture. Can you report back on the details from the Summary tab ...

So hopefully this will help someone else who has seen the same issue where using the datastore snapshot tool to copy. The issue was that we had the file system formatted as reiserfs, when we reformatted it as ext4 the we were able to use the datastore tools successfully.

Yes, I've done this with G7 and Gen8 HP ProLiant servers running on X5660 and E5-2690 CPUs.
This works just fine, as long as you enable VMware Enhanced vMotion Compatibility (EVC) at the cluster level. At this point, you should enable EVC while all of your machines are still the same processor generation. Set it to the Intel® Westmere (L3) level.
When you ...

According to this document you can use multiple processor architectures with EVC.
However, because the Xeon E5 series uses the Ivy Bridge architecture, you will need to use vCenter Server 5.1 - see the final table.
Also, you may not be able to use the whole feature-set of the E5-2600 if you use EVC. The X5675 is based on the Westmere architecture, which ...

Unless you have a very compelling reason, I would split off some of your services on VM2, so that a problem in SQL doesn't knock out your file server, filling the file server knocks out your IIS, etc. With the thin-provisioned disk (as ewwhite recommends), you should still have plenty of room for everything.

The problem is due to localhost dns query on my local network, initiated by my VMware ESXi during the kickstart installation. Indeed, a DNS server was temporally down, and the DNS query timed out.
Theses queries delays VMware service start and induces the command failed (503 service unavailable).
The /etc/hosts file contains « localhost.localdomain» but ...

Yes, there are a few design mistakes here...
Why not use an array of four equal-sized disks in RAID 1+0? Better performance and resiliency and more flexibility.

Will you have write-cache on your RAID array?

For VM1 you could setup a Windows Server Core installation, without a GUI, which only needs around 512MB RAM. I've done that here for our second domain controller, and it's ideal for a 'fire and forget' solution. Remember that it's highly recommended that you have >1 DC, and that at least 1 is on a physical box.

The error means that Veeam cannot identify what blocks have changed. This could have numerous causes, for example, your storage was powered down without to shut down the VMs via guest OS first.
The fix is fairly simple but it does require powercycling the VM, see KB:1113 - How to reset CBT. From the KB article:

Update your ESXi installation to the current build to get around any particular bugs - Right now, the current build is #1065491, so you're behind.
Do you have VMware tools installed inside of your guest virtual machines? You'll want that. For Ubuntu (and other Linux) systems, I prefer to use the VMware OSP packages to handle the tools. See this post for ...

You can convert the drive from a thick-provisioned disk to a thin-proivisoned disk. We're missing a little information, though. How much of the 100GB is in use right now? If it's say, 60-70GB, is this exercise worth it?
The process is simple in a vSphere situation where you have the ability to migrate the VM to another datastore. If you need to do this via ...

I don't even bother checking VMware tools versions on my Linux guest virtual machines now with the frequency of updates to ESXi and vSphere.
I'm a heavy proponent of VMware Operating System Specific Packages (OSPs).
This allows me to handle VMware guest tools independently of the host and control updates/installation at the Linux package manager level. I ...

For those who've wound up in this scenario and have found this forum, I hope you read all the answers because Choppers is wrong - IT_Architect is correct.

This was solved by making the SAN connections 1 to 1 via the switchports. Allowing all the SAN vlans on all the ports messed the setup up.

This is happening because you have more than one path to the same disk, but ESXi doesn't support that using LOCAL. VMWare only supports other methods such as ALUA.
If your array supports ALUA (for instance), you can manually tell ESXi just that:
esxcli nmp satp addrule --satp="VMW_SATP_ALUA" --vendor="SCST_BIO" --model="^r* \
--description="SCST with ...

Make sure you have a working backup of the VMs and of the ESXi configuration. Schedule a downtime of at least a few hours.
You can download a Dell OMSA 7.1 Live, boot the ESXi from the CD and reconfigure the array. You can expand the current volume, or you can add a new volume.
Then you will be able wither to create a new VMFS or to expand the current one, ...

The answer is NO, kinda... But probably no in your situation.
I use LACP (with a switch) over 10GbE ethernet to my NexentaStor storage servers... but that's something that is only possible via VMware 5.1 and through the use of distributed vSwitches. That's a feature only available at the vSphere Enterprise Plus license tier.

I noticed that the resource was named tsclient. After a little search I realised that it was the RDC I'm using to connect that shared my local files. The share disappeared after it was disabled in the RDC settings.

I'd first want to know how you've configured your ESXi server(s). I'm assuming you're running a single ESXi instance with local storage (i.e. SAS drives in a RAID configuration) so you're not having to deal with storage networking like iSCSI, etc.
Assuming you have two NICs, I would dedicate a single physical adapter as your VMKernel adapter and keep that ...

There are too many ways to do this, you'll get tons of answers that are really just opinions on how it should be done.

I don't know Wonderware, but if you're using the pagefile then you're out of memory and everything is continuing more slowly using virtual memory - disabling the page file won't necessarily fix that, it could well just make everything run out of memory and crash instead.

After some (long) conversations with VMware support, I have come to the following understanding:
The number in "Reserved Capacity" is not a function of the memory configuration for the cluster's VMs. It is the sum of several factors: any memory reservations declared on VMs, a value calculated from the HA admission policy, and an additional amount for ...

Not to my knowledge - just the Free or Enterprise edition of the Standalone Converter are available now. I don't think there's any real advantage in having it as a Plug-In.

HyperV runs LINUX systems without glaring issues, but you're subjecting yourself to needless blame whenever their VM's have issues that might not be relevant to the underlying Windows 2012 Server or Hyper-V.

The vmx file simply holds the virtual machine configuration. Simply create a new VM using the vSphere Client and associate your current vmdk files with it.

Looks to me like this is a function of you having set the HA cluster admissions control policy to "Percentage of cluster resources reserved" and given it a 50% reservation. So that's working as intended.

Your question is pretty vague, so use whatever you have expertise in. If your people know Hyper-V then use that, if they know VMware use that.
