There is an ESXi 6.7 server:
In Web Client, I can launch VMRCs
I would like some technicians to launch VMRC of some VMs without having to log in to the Web Client first.
How can I do?
Currently I'm forced to install a remote control tools on the VM, but it's something I do not want to do.
Thanks in advance for any advice.
I am confused about the information shown in the Web Client regarding the space occupied by the VMs.
For example, in ESXi 6.7:
A VM has a HD (Thin provisioning) of 100GB.
n Windows, 21.6GB are used.
36.11GB is reported in the Web Client
In a second VM there are two HD of 80 and 120GB (Thin Provisioning).
In Windows, 29.5 and 1.5GB are used.
213.13GB is reported in the Web Client
What is this data in Web Client?
Hi Experts,
We have a 4 Node Vsphere cluster (HPE DL380 Gen 10, with 2 x 10GB/s uplinks to Aruba 5406 switches, and 2 x 16GB/s FC to SSD HPE 3PAR 8200 Storage Array), running Vsphere 6.7. Vmotion and Storage Vmotion is extremely fast, as would be expected, but when copying data between Microsoft Windows 2012/2016 VMs, it slows down. Each VMware has 1 x VMXNet3 nics and all VM Tools are installed. It pics up as 10GB/s in the OS.
When I copy a Windows ISO file (5.7GB), I get 100Mb/s between VM/s, no matter how I copy the file and which direction. Virtual Machine Version is version 11, so the version should have no issue. LSI Logic is the controller.
Can you please advise on where to start looking for answers?
Regards
I have come across an interesting issue with a new HPE platform. The system is running within a C7000 BladeSystem, with BL460c Gen9 blades.
We have noticed some degradation in performance on iSCSI connection (using the Software iSCSI initiator), this traffic runs over vmnic1 and vmnic2 details from the NIC list are below.
| vmnic1 0000:06:00.1 elxnet Up | Up | 10000 Full | 32:a6:05:e0:00:be 1500 Emulex Corporation HPE FlexFabric 20Gb 2-port 650FLB Adapter |
| vmnic2 0000:06:00.2 elxnet Up | Up | 10000 Full | 32:a6:05:e0:00:bd 1500 Emulex Corporation HPE FlexFabric 20Gb 2-port 650FLB Adapter |
Each NIC is reporting at 10000 Mb full, however I am not able to set the speed on the ESXi server. vmnic1 reports the following for advertised link modes;
[root@ESX:~] esxcli network nic get -n vmnic1
Advertised Auto Negotiation: true
Advertised Link Modes: 1000BaseKR2/Full, 10000BaseKR2/Full, 20000BaseKR2/Full, Auto
Auto Negotiation: true
Where as vmnic2 reports the following modes
[root@ESXi2b-14:~] esxcli network nic get -n vmnic2
Advertised Auto Negotiation: false
Advertised Link Modes: 20000None/Full
Auto Negotiation: false
Confused, the settings are identical for these within OneView. Both NIC's are using firmware - 12.0.1110.11 from SPP 2018.06.0. The HPE ESXi image has been used including driver version 12.0.1115.0 which shows as being compatible on the comparability guide VMware Compatibility Guide - I/O Device Search.
Has anyone else seen this issue? If I try and manually set the speed/duplex settings via esxcli it fails with the following error in the vmkernel.log
2018-08-14T23:49:41.361Z cpu20:65677)WARNING: elxnet: elxnet_linkStatusSet:7471: [vmnic2] Device is not privileged to do speed changes
As a result of this when using HCIBench to test the storage throughput the 95%tile_LAT value is reading excessively when traversing vmnic2 - 95%tile_LAT = 3111.7403 ms
Any thoughts??
I have installed ESXi 6.0 on my machine and my server is having Network controller: Realtek Semiconductor Co., Ltd. RTL8111/8168 PCI Express Gigabit Ethernet controller which is not displayed in network adapters due drivers not found.
what is the solution for this
I've read up on forums, mailing lists and on The Register that there seems to be a severe hardware bug with Intel CPUs:
'Kernel memory leaking' Intel processor design flaw forces Linux, Windows redesign • The Register
There are Linux patches in the works, and Microsoft will release patches during January's patch tuesday. Is ESXi vurnerable, and if so, when can we expect a patch for this? Since it's a critical issue, it will require lots of patching and planning - any heads up would be appreciated!
Today I logged into vSphere and this notification came up.
Lost connectivity to the device mpx.vmhba32:C0:T0:L0 backing the boot filesystem /vmfs/devices/disk/mpx.vmhba32:C0:T0:L0. As a result, host configuration changes will not be saved to persistent storage.
And in the event log as well:
Bootbank cannot be found at path '/bootbank'
I did some research and it suggested that my USB drive (on which the ESXi was installed) had failed. Yes I know there are a gazillion of posts on this issue but I believe mine is a bit different:
So, I did not quite believe my USB drive died so fast (not even 1.5 years and I am not a heavy user), so I pulled it out and put it into my computer, and 3 partitions came up, the USB drive was successfully recognized.
Then I put the USB drive back, SSH into the ESXi and "lsusb", my USB drive showed up as "Bus 02 Device 0b: ID 0781:5580 SanDisk Corp. SDCZ80 Flash Drive".
Now, if I am to play it safely, my best bet would be to replace that USB drive. However, I am not sure if my USB drive has actually failed?
Update: It does show "Input/output error" when I try to navigate into /bootbank in SSH.
/vmfs/volumes # ls
ls: ./79a964e1-88c0598a-7b89-b1a18986d360: Input/output error
ls: ./28b21ce3-3914b9a5-1fea-afb54459361e: Input/output error
ls: ./54b1487c-dce8d390-11e2-0cc47a455f8e: Input/output error
I am still a bit skeptical about whether my USB drive has actually failed. I am going to install ESXi on another USB drive and try it.
hi all!
i just upgrade from 5.5 to 6.5 and when i try to add my usb3 hd its not working ...
the only usb device available is this avocent mass storage function.. it was working fine on 5.5
any clue ?
regards
you see lsusb result and usbarbitrator is on
I am having problems with connecting a proprietary device to an Ubuntu 16.04 installation which is a guest on an ESXi 6.7 host using the physical RS232 port of the motherboard i.e. "Use physical serial port". The problem can be reproduced by connecting the failing RS232 port using a crossover cable to a PC running Ubuntu 16.04 on "bare metal". Install minicom on both Ubuntus and then configure them both to use 115200 8E1 (probably irrelevant) then enter 17 characters into the ESXi minicom. After the 16th character no characters are sent until a character is sent from the non-ESXi minicom. Characters flow correctly in the other direction.
I have changed my proprietary protocol to send a byte stuffing flag byte to "ESXi" after every 4th character sent from "ESXi" and this works well.
I am reasonably sure that the RS232 ports worked correctly with ESXi 6.5.
This was tested on multiple motherboards using the "embedded" serial port including an Asus P10S-X. I also tried Ubuntu 14.04.
I want to know how ESXi can share data between the Host and Guest os, such as shared folder in vmware Workstation. Or how can the Guest OS recognize ESXi storage?
Hello everyone,
This will be my First post ever on the VM Community.
I've been searching but i've found no solution so far.
First things first. I'm a Dutch IT Student researching alot of things for my internship at a security company.
Now of course they won't let me do wicked sick stuff but they do give me a lot of assignments. Wich i've succeeded so far.
But for my next challenge I'm really going to need some help!
Okay here goes. I'm researching how to connect 2 vms hosted on different physical hosts.
The picture below describes briefly what I'm trying to achieve.
I've left out my IP Table because i feel like there are alot of problems there to (or maybe im just looking over something really obvious.
So i have a 24 port Cisco SF300 Series Switch. and 2 physical machines.
One is a host with ESXI 6.5 The other runs ESXI 6.7.
Ive connected Host 1 to Gigabit port 1 and 2.
I've connected Host 2 to gigabit port 3 and 4.
Now i know there is a possibility to gain a 2GB Linkspeed and thats exactly what i'm trying to achieve here.
But somehow i'm not able to get it to work.
Can someone PLEASE help me out with a guide or example build? I feel like i'm missing things and I've been working on this for like a week now.
I'm clueless and i really want to learn how to do this. But i'm not really getting the support that i've hoped for.
Please educate me!
I want to add an esx 3.5 server (it is using a license server on Virtual Center 2.5) to vCenter 4.0.
Our new esx 4.0 servers are using a License Key, so we do not need a license server any more.
How do I add the esx 3.5 server to the new vCenter 4.0 with out any license problems?
I have 2 questions about my NVIDIA GTX 1060 6GB and ESXI 6.5
1) I have installed the above card on my server and set it to passthrough. Have reserved the same amount of memory as the RAM capacity to allow the VM to boot up.
When it gets into windows10 though, I can see the device, install the drivers but even after a reboot the device is not operational and has a yellow warning and reports:
This device cannot start. (Code 10)
Insufficient system resources exist to complete the API.
Can anybody shed some light on what windows is moaning about and especially what ESXi can do to make it happy?
2) I did a quick search on vGPU. Considering this is a standalone ESXi installation (no vSphere etc), can the physical GPU be shared amongst VMs (like the CPU does)?
Thanks
When PXE installing ESXi 6 on BIOS clients it seems the TFTP requests are not correctly handled.
kernel_bios = /NWA_PXE/$HEAD_DIR$/mboot.c32
append_bios = -c /NWA_PXE/$HEAD_DIR$/BOOT.CFG
ipappend_bios = 2
For every needed file a TFTP client usually perform a "Read Request" asking for the size of the file (tsize) answered by the
server with an "Option Acknowledgment" returning "tsize=xxxx", then the client "Aborts" the transfer and checks that the returned
file size is OK, then the client performs a second "Read Request" this time really transferring the requested file.
On BIOS targets the VMware provided mboot.c32is the TFTP client in charge of transferring the components listed at BOOT.CFG.
mboot.c32 BOOT.CFG but it "forgets to Abort" those request; next it requests
those 151 files "again" this time for really retrieving them.
This presents several problems with TFTP servers (i.e. Serva ) that control the number of orphan TFTP transfers in order to prevent
resource abusive TFTP clients.
On the other hand installing ESXi 6 on UEFI targets presents the classic TFTP initial sequence not leaving behind orphan transfers.
"Read Request"->
<- "Option Acknowledgment"
"Abort" ->
In this case it is VMware BOOTX64.efi (not mboot.c32) the one in charge of the client side of the TFTP transfers.
kernel_efi64 = /NWA_PXE/$HEAD_DIR$/EFI/BOOT/BOOTX64.efi
append_efi64 = -c /NWA_PXE/$HEAD_DIR$/BOOT.CFG
ipappend_efi64 = 2
See the attached Wireshark traffic capture

Dear VMWare community,
Before in version 5.5 i have no issue, but now in 6.5 and also 6.7 my swap datastore is not used by the VM's.
I got this issue with an new installation at a customer, so i created a test setup, where i also have the same issue.
My Hypervisor is stand-alone.
I have 2 datastores, one for the VM, one for the swapping.
VM name = WinSrv with 4GB RAM.
Below: Host \ Manage \ System \ Swap \ Edit Settings, i have set the following settings:
Enabled: Yes
Datastore: datastoreSwap
Host cache: Yes
Local swap: Yes
(VM is restarted)
On the datastoreSwap there is only the sysSwap.........swp
The WinSrv.....vswp of the VM is still at the datastore of the VM.
At the settings of the VM, when u go to VM Options. below at Advanced.
The settings is set to: Default (Use the setting of the cluster or host containing the virtual machine)
It does not matter if i change this to: Datastore specified by host.
I also couldn't find any errors that the datastoreSwap could not be used or anything.
allot of documentation is or old or for vCenter, because i dont have the following "buttons"
The following doc says its for 6.5 but this version does not have vSphere Web Client navigator anymore...Configure System Swap
The following doc says its for 6.7 but this version does not have cSphere Client anymore... Configure Virtual Machine Swapfile Properties for the Host
hopefully someone can help me.
Hi,
I'm using ESXi 6.7. Now I'm having the problem that the snmp service is automatically stop, repeatedly. After the service stops, I can manually restart it and everything seems okay for only 2-3 days.
Here is some log of the /var/log/syslog.log file:
2018-10-17T14:13:44Z Unknown: out of memory [2296311]
2018-10-17T14:13:44Z Unknown: out of memory [2296311]
2018-10-17T14:13:44Z Unknown: out of memory [2296311]
2018-10-17T14:13:44Z Unknown: out of memory [2296311]
2018-10-17T14:13:44Z Unknown: out of memory [2296311]
I found that there is a same issue on ESXi 6.5 here Re: SNMPd stops on ESXi 6.5 and the issue has been resolved in its next patch. So I'm wondering why this problem come back again in ESXi 6.7 and is there any solution to resolve it now?
Thanks
I have a VM with Windows 2016 in Terminal server mode.
Periodically the server has power down with not records in Windows Log, but in log of ESXi is next (screenshots in attachment's)
It can be at work time, when server is using or at night when active is minimal (as well - just closed rdp sessions)
I'm posting this so others might not have to spend hours on the line with support figuring this out.
My environment is older and has the Emulex LPe11000 hba cards. This card isn't discovered oob.
Obviously a problem right. After spending hours on the phone with VMWare support they pointed me to Emulex.
The issue really is that some of VMWare's support personnel don't know where they keep all the VIB files for their OS.
I was able to find the attached VIB here. Import this and apply it and your Emulex card will start working and you can take your hosts up to ESXi 6.
I downloaded the Windows 10 1809 and Server 2019 ISOs the day they became available so I can start working on my templates.
I built the templates with EFI, paravirtual for the C drive and vmxnet3 adapter. I've been using this combo for other versions of windows 10/8/7and windows server 2008r2/2012r2/1016 without issue.
So far Windows 2019 (with desktop experience) seems to be ok at least for a basic vm and guest customization. Haven't tried anything else yet.
Windows 10 1809 on the other hand is very, very slow to reboot after the initial install or even just rebooting after making some changes post install. After installing the OS it took 10-15 minutes for the initial windows setup stuff (user, security settings, etc) to appear . I tried a VM set to BIOS and it seemed faster but was still quite slow. Server 2019 and other versions of windows 10 have no issue.
The hosts are esxi 6.5 and 6.7.
I haven't had a chance to try every combo of BIOS/EFI/vmxnet3/e1000e/paravirtual/lsi sas to see if one is the cause of the issue but was wondering if anyone else had noticed any issues or if it was just me?
Thanks
Hi Community,
this may be kind of an odd question but would it be possible to hook up 4 monitors (and 4 usb mouse/keyboard) to a single physical machine so that 4 people can sit there and each of them uses its own VM fullscreen on one of the monitors?
Reason for this: Retro video gaming with Windows 95/98. I don't have "enough" old hardware so I wanted to use a retired XEON server (since each of the VMs only need at max 500 Mhz of CPU speed) with 4 VMs and the 4 users each have their own Screen and own VM, all connected to the server standing in the middle.
Thanks
Martin
