Hola:
he conseguido la solución del error una bestia, instalo anteriormente en el servidor de destino el vcenter standalone y por eso no permitia hacer la copia.
desinstalelo y despues hagan toda el proceso de copia de nuevo.

Both are very good, but I prefer PluralSight since it has a lot of more training options than CBT Nuggets.

Re: Thinapp Citrix XenApp with Native Citrix Receiver
Hi - I am pretty sure I tried to do this a few years ago for a web portal we had to use for a SaaS suite of applications that combined Citrix web interface with web applications this service provider used. They only supported IE8 at the time we were migration to Windows 7.
I struggled with this and gave up - so sorry that may not be much help for a solution, but I suspect there is no solution. If I had to guess the receiver or older ICA clients may be installing drivers, and drivers I am pretty sure cannot be ThinApped. That is just my guess though. Maybe it was more to do with how tightly integrated the client is with Windows once you install it.
What we ended up doing was finding a happy medium; a version of Receiver where we could still upgrade, but not as new as we wanted to use.

Re: unexplained high write latencies
Hi vtones
thanks for your response. I will do this test tomorrow since here in Switzerland it is late in the evening now ;-)
But what I did already, was to set up a ping with a 4k payload from one host to the other and I had a roundtrip time of about 1ms. But I will do your tests anyway.
Just for my understanding: The "compmgr" isn`t really the device latency, isn`t it? All 3 of these roles combined in addition to the device/kernel latency (gavg at esxtop) are the latency that the vm`s observe? And if I would set the failures to tolerate to 0 and move the vm to the host where the vmdk resides, it would be possible to exclude the network to test the performance right?

Re: packaging a windows 2003 service to run on windows 2008
I thought of a few things to check into.
- One is if you packaged that on a 32-bit OS it could be possible that the 64-bit Windows 2008 server won't run it. So if you did that maybe try a 64-bit Windows 2003 server for your packaging clean machine.
- The second thing might have to do with dependencies. Maybe something was present on your clean machine that you packaged with that is just missing from the newer 2008 server. Perhaps that is DotNet or a c++ redistributable. You could run Process Monitor to see what might be looked for by the services (if it is even starting) and then dying on. Another good tool is SpyStudio (this tool helped me a few times).
- check event logs - maybe something in there is a clue.
- can you run something else in the package and then start the service within the sandbox? that might lead to more questions or things to check depending on what you see if you could try that too.
These are just things I would look info if I was in your shoes. I have not tried to do what you are attempting to do.

Re: Some VMs ( 4 of 5) aren't migrate to second host when first host down.
All virtual machines are stored on shared datastore accessible by both hosts? I'm asking this because on your first picture, the second warning message says the following: vSphere HA did not reset this VM because the VM had file on inaccessible datastore.

Cannot use host NIC with guest only
Hello all
I am not able to use this idea on Workstation Player 12:
Using a network adapter only with the VMware Workstation guest virtual machine (1020359) | VMware KB
In virtual network editor I defined VMnet2 as bridged and linked it to host NIC.
For the host NIC I made sure only vmware bridge protocol is selected.
So guest with VMnet2 only is unable to obtain ip address from DHCP server, not even ping gateway (network unreachable error).
However when I also select both: TCP/IP protocol and vmware bridge protocol on the host NIC, guest obtains IP address fine and can ping internet sites:

Re: Connect-VIServer -AllLinked with Enhanced Linked Mode
From my understanding of Enhanced Linked Mode, the "-AllLinked" parameter unfortunately does not currently work as PowerCLI uses the same connection method as the vSphere Client (Desktop/C# Client).
"You can view and search the inventories of all linked vCenter Server systems within the vSphere Web Client. The vSphere Client does not support Enhanced Linked Mode."

storage vmotion throughput
Hi All,
trying to find any information around troubleshooting storage vmotion throughput. I have a new esxi6 cluster stood up in new datacenter, and working on getting some workload migrated in. Migrating (cold) a couple machines from different sites, and it's taking forever.
one site has 1GB link, 70ms latency, and i'm seeing an average of 10Mbps transfer.
other site has 100MB link, 120ms latency, and strangely i'm seeing more throughput from this link, at ~14Mbps.
(source and destination storage arrays are both good, sub 1ms response times, very little load, and 10GB connected.. )
in either case, the throughput is far below the available bandwidth, although i could see latency potentially causing some of the slowdown. But even with that, i just cant see it being that bad.
Looking around for any configuration options which can be tweaked (TCP buffers or window sizes), or anything else which i can do to improve this.
Thanks
Jared

LSI 9217 SAS is insanely slow, even with SSDs on ESXi 5.1
Hi folks,
I've got a little bit of a frankenstein Dell server and I'm noticing that the storage is insanely slow. What makes it a non-standard Dell is that the original PERC H700 adapter has been removed, and in its place is a LSI 9217-8i controller with a pair of mirrored SSDs. The card was purchased as an 9207, but it was flashed with the compatible 9217 to give it the RAID firmware. There's also an LSI 9200-8e SAS controller in the system with nothing attached to it.
After noticing VM cloning being very slow, I tried from SSH in my /vmfs/volumes/<datastore> directory:
# time dd if=/dev/zero of=testfile bs=1M count=100
100+0 records in
100+0 records out
real 0m 7.59s
user 0m 0.23s
sys 0m 0.00s
That is, create a 100MB file on the SSD mirror. This takes almost 8 seconds! I think that comes out to about 13MB/sec for a sequential write. With a linux live CD, the same command takes a fraction of a second, and dd reports over 700MB/sec data transfer rate.
Just to make sure that my test is fair, I did the same sort of test on a similar server running ESXi, but with spinning-platter disks hung off of the H700:
# time dd if=/dev/zero of=testfile bs=1M count=100
100+0 records in
100+0 records out
real 0m 0.42s
user 0m 0.31s
sys 0m 0.00s
ESXi is the latest available 5.1 patch. The LSI driver has been updated as outlined here: http://adriank.org/how-to-update-mpt2sas-driver-on-esxi-5/
The LSI firmware has been flashed to match the updated version of the driver used by ESXi (19.0)
Why is the LSI SSD storage so slow? I wouldn't expect it to be because of the RAID-enabling flashing, as when booted to Linux the storage is amazingly fast.

Re: Some VMs ( 4 of 5) aren't migrate to second host when first host down.
Hi,
If you are having able to access the datastore from both the ESXi host then just try to re-configure HA i.e. disable and re-enable HA and check it out.

vmware ws 12 - network issues
I am suddenly unable to connect to the network on any of my VMs. I have uninstalled and installed vmware and installed the latest 12.5 build. I have used the network editor (run as administrator) to reset the network configuration. The problem exists across every VM, so it is not machine dependent. It appears to be an issue with the underlying application. Of interest is that the network editor is recreating "Ethernet 2" and does not create the more standard "VMnet8". VMnet1 does get created. the system has now created four separate Ethernet 2 connections.
Both bridged and NAT have been tried and neither works.
Anybody having similar struggles?

Re: Upgrade vCenter to a different host with new hostname
This is what I do because I am not a fan of upgrades from one version to the other. There are migration scripts out there than can help you do this. InventorySnapshot on the Flings website is one of the ones I use. I have two large user environments (2000+ VMs each) with lots of folders with the same name so the first thing I do is run a PowerCLI script that renames all entities to its database name. Then I run the InventorySnapshot utility to do the data dump and then the insert into the new vCenter. After everything is in the new vCenter I run the rename script to put all the original names back. There are always a few things to clean up by hand but I've been doing this for several upgrades now. When you are done you have a new vCenter and a new database. Of course, there is no history so if that is an issue this may not be the best thing for you. For us, it is not an issue. I like starting with a "fresh" setup every new version.

Re: SCCM VCM overlap
Depends on your environment. We currently have VCM for compliance reporting, but use SCCM for Windows patching and patching compliance. VCM is great because we can report compliance on Windows, Unix/Linux, and our Virtual Infrastructure. Basically you can report on your entire environment and see the compliance status in vCenter and/or vRops.
That being said, the road map for VCM is that compliance will eventually be rolled up into vRops but I haven't been able to get much more out of VMware. The latest vSphere 6 Hardening Guide is already supported in vRops.

Re: vRO & Downloading via REST
Thanks again for the response. I've been messing with this for a little bit now, and after making various degrees of progress using various methods (attempting to use a PowerShell host to do the REST command to download the binary, trying the Download plugin, etc), I'm circling back to your initial suggestion to using the Command scripting class.
The vRO 7 documentation states that "By setting the com.vmware.js.allow-local-process system property to true, you allow the Command scripting class to write anywhere in the file system. This property overrides any file system access permissions that you set in the js-io-rights.conf file for the Command scripting class only. The file system access permissions that you set in the js-io-rights.conf file still apply to all scripting classes other than Command."
What I'm seeing, however, is that any command that tries to create a file in the file system (via curl or even something as simple as date >> newfile) results in errors. Manually running the commands while logged into the vRA appliance, of course, works. Is there something else I'm missing that I need to do to allow these commands to work?
Thanks again for any assistance.

Re: LSI 9217 SAS is insanely slow, even with SSDs on ESXi 5.1
It might be worth mentioning that the SSD drives are SATA. This configuration works fine with FreeBSD and Linux, so it'd be strange if that were related to the problem here. I'm mentioning it just in case, though.
