Optimizing physical adapters
Imagine 3 VMware ESXi 5.5 servers members of a vSphere infrastructure.
Each server is confngured with:
- 1 physical adapter associated with FT and Management Network
- 1 physical adapter associated with Vmotion
- 1 physical adapter associated with iSCSI (on a dedicated physical switch)
- 2 physical adapters associated with production VM port groups
I need to reduce che number of physical interfaces.
Can I associate Vmotion, FT and management Network to the same physical adapter?
Can I associate all the production VM port gropus to the same physical adapter without recreating the port groups to be moved?
Is there any documentation about the best way to associate VMkernel ports and port goups to physical adapters?

ESXi 6.5 and Intel 750 400 GB problems
I installed an Intel 750 GB PCIe SSD last week, in order to get some of my VM's better disk performance. After running without problems for almost 7 days straight, something happened. All VM's that had their boot-disks on the SSD were inaccessible, and both the ESXI Web UI and the console was slow and practically unusable. Had to make "hard reset". After the reboot everything was back to normal. Same thing happened again after another 2 days. VM's that was running on the RAID-array wasn't affected and was accessible.
The nvme driver is "intel-nvme" version 1.2.1.15-1OEM.650.0.0.4598673.
Before I installed the drive I updated the firmware to the latest available.
Motherboard: Tyan S5510GM3NR, BIOS v2.02
CPU: Xeon E3-1265L v2
If/when it happens again I'll try extract the system logs and see if it give any clues.
Known issue? Possibly a bad drive?

ethernet0.pciSlotNumber silently resets
How do you set ethernet0.pciSlotNumber? Every time I try to set it back to 33 from 192 it resets itself back to 192. (I had removed and replaced the NIC card to change it from E1000E to VMXNET3.)

VC has lots of alert : alarm.HostConnectionStateAlarm event: host connection lost status=not respond
Hi,
Yesterday we entounter an issue that VC has lots of alert about host . events shows that host connecion lost not respond. but restored normall immediately.
we first thought that if has a short network outage was raised during the triggerd alert period. But network team definited sure that there is no any problem related network . so we foucsd on issue between vCenter and ESXi if has any problem. below is detail info
VC version ：5.5
ESXi version:5。5
issue time：UTC +0 8:47 20th July 2017
event: VC has lots of alert : alarm.HostConnectionStateAlarm event: host connection lost status=not respond. restored normall immediately.
I also checked vpxd vpxa vmkernel,hostd log files and actually not found any value info about host connection lost.
we sure that we have taking a snapshot for VC during that time(issue time)
I don't know if take a snapshot for vC caused ESXi host lost connection. (this VC connected hundreds of host. but only dozens of host happened host connection lost)
anybody if have an idea or methond to investigate this issue. Any suggestion provided will be appreciate . thanks for you in advance.

vSphere ESXi 6.5.0 Hardware Sensors
Hello Everyone,
I have a Q170 based motherboard and have successfully loaded ESXi 6.5.0. However, ESXi does not display any Hardware Sensor Data and reports "No Sensor Data Available".
Does ESXi require BMC or IMPI to obtain hardware database? Does it not get at least basic sensor information from the CPU sensors, etc.?
Thanks

Problem with PXE boot
Hello.
In our network I have a curious problem.
We have three hosts with vsphere 6.0 Update 2.
We're using XenDesktop 7.14 with PVS 7.14.
For the moment we're preparing Win7 x64 Prof. SP1 machines. The machines are booting over PXE.
The older machines (Win7 x86 Prof. SP1) are booting from all three hosts.
The new machines are booting only from the host, where are they created.
Machines, which are migrated to another host don't find a pxe device.
I compared the network setting. There are no differences between the network setting are equal. All machines are using vmxnet3.
For the moment I don't have any idea, where the problem is.
Any ideas???
Thanks in advance for your answers.
Best regards

ESXi 6.0 U2, Passthrough Video Card, Hang/Freeze
Hi,
I'm trying to build an ESXi home white box for gaming, but one of my requirement is to have a board with IPMI KVM for remote administration.
Right now i have this setup:
MB: Asrock Rack EPC602D8A
CPU: Intel(R) Core(TM) i7-3820 CPU @ 3.60GHz
RAM: 20GB
3 x 4GB DDR3 PC3-10600 (Kingston 99U5471-020.A00LF)
1 x 8GB DDR3 PC3-10600 (Kingston 99U5471-052.A00LF)
RAID CARD: LSI MegaRaid 8888ELP
GPUs TRIED: NVIDIA GTX480 and AMD Radeon HD7800
ESXi: 6.0 U2
The problem i'm having is that when i start my VM that has the GPU with passthrough causes the ESXi to complete hang.
Anyone as seen this problem before? Any suggestion? Does anyone knows of any motherboard with IPMI (AMD or Intel) that would work?

Core file in Home folder after installing VMware tools on Linux Mint 18.2
Fresh installs of Linux Mint 18.2 (Ubuntu 16.04 LTS)
After installing VMWare Tools and rebooting a core (program crash data) file is found in the Home Folder. This is happening on VM's on both ESXi 5.1 U2 Build 1483097 & ESXi 6 U2 Build 4600944.
The file is approx 6 MB in size. I've deleted it, but it is recreated the next time the VM is rebooted.
Viewing the file with Nano it appears to be related to the graphical x environment as there are a number of references to gtk-default-menu items, toolbars, styles, as well as listbox's, menu buttons, radio buttons, background colors, etc.
A Google search for this turned up a post in the Linux Mint Forum from Dec 2013 for this same issue, but the OP never posted a followup to say what the issue was.
It doesn't appear to be causing an issue with stability, but the VM's have only been running for a couple of days.
Has any one else seen this?

vmware deploy from template with guest customization error
customizon of a new vm from template goes in error
in the events of the vm i see :
"An error occureed while setting up network properties of the guest Os. See log file C:\windows\temp\vmware-inc\guestcust.log in the guestos for detail"
in this log file there's just an error reporting "[2017-07-21T14:52:08: : ERROR] error number 80010106, No error message found for error code -2147417850 (0x80010106)"
i've tested the sysprep manually inside the VM and it ends good
it happen after installing some application (about CAD environment)
if i get back to the snapshott taked before the application's setup , the deploy ends good
i also noted that, after installing hte application, when i deploy the VM from the template the network device comes up as disconnected (both "conncted" and "connected at power on" are not solected")
thank you for support

Stuck temporary snapshot (created by Veeam Quick Migration) - how to get rid of it?
This past weekend, I ran the VEEAM Quick migrate utility moving the VM from an NFS datastore to a local datastore. It got stuck at 99% but appeared to create the new VM machine. I started the VM and it is running fine and has been for almost a week. The datafiles on the old NFS datastore have not changed since Sunday thus there seems to be no interaction with those files.
I noticed that there is a snapshot called "Temporary snapshot for Veeam Quick Migration" on the new VM. When I try to delete then through Vcenter, I get this message:
Task Name,Target,Initiator,Queued For,Start Time,Completion Time,ServerRemove snapshot,VM2016,VSPHERE.LOCAL\\Admin,3 ms,7/18/2017 10:47:11 AM,7/18/2017 10:47:12 AM,vcenter.localdomain.com "A general system error occurred: vim.fault.GenericVmConfigFault
I contacted VVEAM support. They said that, even though the stuck snap shot is a snapshot called "Temporary snapshot for Veeam Quick Migration" that was created by the Veeam Quick Migration it was not Veeam's problem. The explanation was "When we make the API call through the manage object browser Veeam can't see that snapshot 4. This causes a timeout on our side because the host is not reporting back anything about the snapshot. Like I said before we only make API calls for snapshot creation and consolidation. I would advise to reach out to VMware to get that taken care of. "
So...all that said, I'm still stuck with a stuck snapshot.
Anyone have any ideas?
Thanks!

non persistent storage error message
Hello,
Have a fresh new install of vsphere 6.0 Update 3a dated 7-11-2017.
The vsphere client is giving me an error message on the splash screen.
"Configuration Issues
System logs on localhost.localdomain are stored on non-persistent storage"
I have other servers in the cluster that were upgraded from earlier 6.0 that are not getting this message at all and are in fact logging to the local datastore, just not /scratch though.
No configuration other than assigning an ip and password to the esx server has been done to the new servers.
We have no desire to log host information to shared storage.
Thanks

Purple Screen on Cisco UCS server with ESXi 6.5 Build 5146846 (March 9, 2017)
Last week I patched our (7) lab ESXi 6.5 servers to the current patch level (Build 5146846 - from March 9, 2017). The (5) Dell servers have been running flawlessly on this new patch level. However, the (2) Cisco UCS B200 M4 servers have been crashing constantly with Purple Screen of Death (PSOD). I verified that the Cisco UCS servers are running the current firmware (BIOS & VIC) supported by Cisco with ESXi 6.5, and I also used Update Manager to apply the current Cisco Image Profile ("Vmware-ESXi-6.5a.0-4887370-Custom-Cisco-6.5.0.2-Bundle.zip" from 2017-03-14), to get the current drivers, but that did not help -- PSODs continued. The PSODs keep occurring on both ESXi hosts in the 2-node Cisco cluster, rendering a complete cluster outage. First, one ESXi host PSODs. Then a little while later, the second ESXi host PSODs. Sometimes the PSOD takes 5 hours to occur, sometimes it only takes 25 minutes. (Another PSOD occurred while I was typing this post, after a reboot of the blade just about 25 minutes earlier.) I've captured dozens of PSOD screen shots, and every single one contains the following lines:
NOT_IMPLEMENTED bora/vmkernel/sched/cpusched.c:9581
On each PSOD, a different VM name is listed two lines below the above error code, so there is no consistency as to which VM triggers this panic.
The interesting thing is that the (5) Dell servers are humming along without issue on this patch level. The Cisco servers are using Intel(R) Xeon(R) CPU E5-2670 v3 CPUs, while the Dell servers are using earlier generation CPUs (Sandy Bridge or Westmere). Both the Dell servers and Cisco servers are using vSphere Replication 6.5. The Cisco servers are running a heavier load of VMs, many of which are using multiple vCPUs, so perhaps there is another vCPU scheduling bug that is being triggered?
We have vRealize Log Insight running, and the following are some of the last messages sent by the ESXi host after PSOD:
[Originator@6876 sub=VpxaHalCnxHostagent opID=WFU-491dcb0b] Applying updates from 215636 to 215637 (at 215636)
[Originator@6876 sub=PropertyProvider] RecordOp ASSIGN: guest, 45. Sent notification immediately.
The vRealize Log Insight VM is running in the Cisco cluster, so I might be missing some of the most important log entries right at the time of the PSOD.
Anyone else running into this?? (Note that this is a "lab" environment, so it's not production impacting. This is exactly why we have a "lab" environment!!!)
Below is one screen shot example of the PSOD. They all pretty much look like this:

More cores vs More GHZ (Microsoft licensing)
Hello,
As everybody probably know microsoft changed their licensing model for windows 2016 to a per core model.
In my hardware designs i always kept a 1:3 ratio for Cores/vCPU's and try to use a cpu with 2.6 ghz.
Now with the new modelling costs of licensing can go through the roof. so the question i have is pretty simple.
Can i use a higher ratio like 1:4 if i choose a cpu with more ghz per core.
I understand it is not an exact science..

onetime.tgz not found problem.
Hi there,
I recently installed VMware-VMvisor-Installer-201704001-5310538.x86_64 on my intel nuc skull cayon.
All things processed successfully during installation.
But after reboot of my installation, system stop at loading onetime.tgz
It is said onetime.tgz not found, and listed an checksum md5 and a caculated md5(which is 32 zero).
I'm pretty sure the iso file's md5 is exactly same with download page offered.
Anyone knows how to solve this problem ?

raspberryPi central UPS hub for shutting down VMs/Esxi?
ESXi: 6.0.0.33801214
vSphere: 6.0.0.3016447
vSphere on Win2008 sever
ESXi on its own machine.
regarding UPS and how to get VM's to shutdown gracefully and then ESXi shutdown gracefully...
small home network with:
i have 3 APC 1500 UPSs connected to a raspberryPi v3, running fedberry and apcupsd.
i have one APC 1500 UPS connected to a Synology NAS, this has the VM's installed on.
during power outage, UPSs kick in, but i don't think the VMs or ESXi are shutting down gracefully. luckily, all boots back up fine. the Synology with direct UPS connection does suspend the Synology disks, thus the VMs are not accessible during that time. then 15min later Synology shuts off.
instead of the UPS on Synology, i would like the raspberryPi to be able to signal the ESXi machine to start gracefully shutting down the VMs on Synology, and then have the ESXi shutdown a few minutes later & then Synology & the Win2008 server shutdown.
is it workable that apcupsd on this raspberryPi can signal the ESXi host to do this? or do i need to physically connect one of these APC UPS to ESXi host machine and configure something on the ESXi host?
i would like to have the raspberryPi be like a central hub for UPSs management versus connecting these UPSs to various machines.
