Agent Unreachable Status for VDI Clients

January 21, 2014, 10:33 am

Hey guys,

 

We have an automated pool of 150 desktops which get refreshed on logoff OR after being disconnected for >60 minutes. I've noticed that we have been gradually getting more and more "Agent Unreachable" status's for our VDI desktops over a period of 4 - 6 hours until I go in, remove the VM's from disk and let provisioning re-provision the VM's to reset them. Doing a desktop reset does not fix the issue. I have made sure that the VM's are receiving IP addresses from DHCP and they are. We are not running out of addresses since these 150 desktops have 250 IP addresses in the DHCP scope with 15 minute lease times.

 

We are running VMware View 5.2. If any more information is needed, just ask.

Gráfico de máquinas virtuais mostra uma informação de consumo de disco errada

Prezados,

 

Estou sofrendo com um problema muito chato que é o seguinte:

 

Atribui um disco de tamanho 100GB para uma VM. Até ai tudo bem, porém quando verifico no gráfico do vCenter "By Virtual Machines (Top 5), onde mostram as VMs que mais consomem disco, ela aparece consumindo bem mais... aliás, ela nem é uma das que mais consomem, porém ela insiste em aparecer neste gráfico afirmando estar usando praticamente o dobro.

 

Já procurei informações na internet, mas nada que pudesse ajudar a pelo menos saber o por que disso. E o estranho é que o alerta de espaço do Datastore já me alertou sobre o consumo excessivo. Alguém poderia me ajudar por favor?

NSX and VMware tools

January 6, 2017, 11:32 am

We are about to upgrade our underlying vSphere infrastructure that is protected by NSX w / DFW. 

 

-  we are moving from vCenter \ vSPhere 5.5 u3a to 6.02,   NSX is already at 6.2.4.  

 

-  We can't do this all in one window, it must be staggered

 

-  the order is vCenter first, then hosts, then VMtools in VMs, then VM vHardware.

 

-  I want to be certain that after we upgrade vCenter and the hosts, that we won't have any issues with out of date VMtools and NSX

 

 

When I accessed the VMware Solution Compatibility matrix, I run a query:   NSX 6.2.4  against all VMtools versions, see screen shot below..

 

- I don't see any mention of OVT, and am still uncertain if we can use them or if we must stick to native VMtools on ESXi

-  I get an output of compatible versions that doesn't make sense to me, the standard VMtools that accompany vSphere 6.02 is none of the below, its 10.0.6:

 

Can someone shed led on this for me?   It doesn't seem right to me at all since we have NSX 6.2.4 running now against 5.5 u3a with VMtools at "vmx-10"

 

So, I need someone to provide expertise:

 

1)  Can I use OVT tools with VMs protected by NSX DFW?

2)  Will I have any issues with NSX compatibility after upgrading VMtools to 10.0.6 after we upgrade to vSPhere 6.02?

 

Here is a screen shot from the solution compatibility guide:

HCIbench - IP Assignment Failed when running test

I've deployed the HCIbench ova on my VSAN, following the instructions in the User Guide. I logged into the web interface and setup a test, generated a parameter file, downloaded / uploaded vdbench, saved the config, and successfully validated the config. But the test fails with IP errors:

 

Deployment Started.

IP Assignment Failed, Deleting VMs If Deployed...

VMs Deleted

Testing Failed, For Details Please Find Logs in /opt/automation/logs

Please Cancel And Re-Run The Testing

 

When I look at the appliance in vSphere, I see that it has 2 IP's; one is correct for our network, and the other is not: 192.168.0.1.  I can obviously web into the appliance, so I know the LAN IP is working. I guess maybe I don't understand this part of the guide:

 

"...map the “Public Network” to the network which the HCIBench will be accessed through; if the network prepared for Vdbench Guest VM doesn’t have DHCP service, map the “Private Network” to the same network, otherwise just ignore the “Private Network”."

 

Help? Thanks!

Hello everyone,

I have been pulling my hair out to get my vsan health green with this AHCI controller compatibility. I'm using two Supermicro 5019S-MR 1U servers updated to the latest bios, I have also tried to disable the native AHCI driver and let it use the SATA AHCI with the correct version that is compatible with the VSAN list but it still gives me the warning. I am hoping someone can see something I don't. I have inputed the screen shots below. ANY guidance on this issue is greatly appreciated!vsan.pngvsan2.png

こんにちは。

 

ホスト ： Max OS X 10.6.8 (Snow Leopard ) 32bit

ゲスト ： WindowsXP Pro SP3 32bit　　です。

 

Mac OS X El Caritan へのアップグレードをして、VMware Fusion 3が使えないので、

バックアップストレージから、OS X 10.6.8 にダウングレードしました。

再起動後に、ゲストのVMware Tools が無くなっていたので、インストールし直しました。


以下、不具合です。


（１）起動モード？というのでしょうか？

　　マウスのカーソルが、ゲスト・デスクトップ内で止まらずに、

　　ホスト・デスクトップへもスムーズに移動します。

　　以前の正常時には、ゲスト、ホストそれぞれのデスクトップに切り替えてマウスを使用していました。

　　画面切り替えコマンドを使用しても同じ状態です。


（２）ゲストのウィンドウ画面を拡大すると、４：３サイズのままで、両サイドが黒画面になります。

　　ビデオコントローラ（相互VGA）のインストールができません。 ← これが原因なのでしょうか？


どうか、私に解決方法を、ご指南くださいませんでしょうか？

何卒よろしくお願いいたします。

Unable to Select VDP External Proxy Host

We have recently deployed qty(2) VDP appliances and loaded the patch so they are accessible in the vCenter web client. However, we also need to deploy some external proxies to backup some VMs via Hot-Add. However, after logging into the configuration portal for the VDP appliance and selecting "Add external proxy", the first page displaying Host and Storage contains blank drop down menus with no hosts available to select. I couldn't find any posts about this, any ideas?

 

This is VDP version 6.1.2, vCenter 6.0U2 and a mix of ESX 5.5/6.0. I did redeploy an appliance to be on the same subnet as vCenter, with similar results.

Pass-through USB controller stops working after 10 seconds of inactivity

Hi everyone,

 

I am having an issue with ESXi 6.5 when I pass-through an Intel 9 series USB controller to a Windows 10 VM. My mouse and keyboard stop working if left alone for what seems to be 10 seconds. I then see this in the log:

2017-01-07T00:31:33.995Z| vcpu-3| I125: PCIPassthru: 0000:00:1d.0 : barSize: 1024 is not pgsize multiple

 

I actually see that many times in the log before things stop working but always a final one at the 10 second mark after letting go of my mouse. If I keep moving the mouse it'll keep living.

 

Here's more from the log which relates to the controller:

Details of the VM:

Hardware version 13

EFI boot

All defaults other than CPU set to all for 4 cores and 4 cores per socket, removed SATA controller, and added PCI device (my USB controller pass-through).

Windows 10 Pro x64

Tried with and without vmware tools installed.

Device manager shows controllers and devices without any errors at any point.

 

Details of the host:

ASUS Z97M-Plus

Intel Core i5-4690K (3.5Ghz, 4 cores)

16GB DDR3 @ 2133mhz

Samsung 840 PRO 128GB SSD (using ESXi legacy AHCI drivers since the native drivers are buggy/slow)

9 Series Chipset Family USB EHCI Controllers


I've also tried using ESXi's vmkusb driver so that it reverts to the legacy driver instead, but it makes no difference.


Any help is much appreciated!! This is for a gaming VM setup and I have no room to try other controllers, either.

Snapshot reverts Automatically

Hello,

 

Recently a VM reverted back to a snapshot that was not invoked by human intervention. We currently have no automation tools or scripts setup to where this could have happened by some preprogrammed process. Also we only use persistent disks with these VMs. This has happened to us on one other occasion. At this point we are perplexed as to how this may have happened and we are looking to see if anyone else has experienced the same issue and if you have how have you prevented it from happening again.

 

Thanks for any insight.

Network problem about SR-IOV in VIO 3.0

Hi expert,

I have deployed a VIO 3.0 environment based on DVS. I want to use SR-IOV VF (intel 82599) to improve the network performance.

Currently the VM had already boot up, and the VF driver was loaded successfully. from the vsphere, I can see the VF occupying with command "esxcli network sriovnic vf list".

After I configured the IP address on the interface, it can't reach other servers, no matter the other server is located on the same host or not.

 

I captured the packets on the physical switch, and found out that the VM with VF could send the ARP request out, and other server had response the ARP reply,

but the VM could not receive the ARP reply.

And I also captured the packets on virtual switch's uplink interface. If the another server which located on the same host, the ARP reply packets could be captured on uplink interface;

but if another server which located on the different host, the ARP reply packets couldn't be captured.

 

I have been in puzzled for a long time...... Could anyone give some advice? Any help would be appreciated!

Добрый день!

У нас есть хранилище HP 3PAR 7200  и несколько хостов ESXI 5.5

Hardware Acceleration: Supported.

Делал тест работы VAAI миграцией виртуальной машины с одного Datastore на другой.

Виртуальная машина 350 GB.

При включенном VAAI время миграции составило 922 с.

При отключенном VAAI время миграции составило 1104 с.

Разница по времени как по мне не сильно серьезная всего 3 минуты.

Подскажите пожалуйста это нормальные показатели или я слишком много ожидаю от VAAI?

I'm only seeing a single adapter in my Storage Adapters section and it isn't iSCSI. Am I missing something in my configuration or is this just not possible?

Why the rx buf length and vmdq num of intel ixgbe are decreased in vCD(deployed with VxLAN) and VIO (deployed with VDS) scenario?

December 25, 2016, 11:07 pm

Hi expert,

 

We use intel ixgbe NIC in our host, and we have set the option as below to enable 8 VMDQ for each NIC.

esxcfg-module -s "InterruptType=2,2,2,2 VMDQ=8,8,8,8" ixgbe

 

If the host is not prepared by vCD(use VxLAN) or VIO(use VDS without VxLAN), the physical NIC's VMDQ numer is 8, and pre-set maximums rx buf is 4096.

 

Buf if we prepare the host with vCD(use VxLAN) or VIO(use VDS without VxLAN), the physical NIC's VMDQ numer is 4, and pre-set maximums rx buf is 512.

 

These change will obviously affect the network performance of our application. So I want to know is it the system implementation or something could be configured?

 

Any reply would be appreciated!

 

The normal situation of rx buf is like below:

Ring parameters for vmnic6:

Pre-set maximums:

     rx_queue_6_packets: 0

     rx_queue_7_packets: 0

     rx_queue_8_packets: 0

 

after prepared with VxLAN or VIo, the value was changed:

Ring parameters for vmnic8:

Pre-set maximums:

vMotion and USB connections through Console

I have someone that has a console session open and a USB device connected to the VM on a ESXi 5.5 host.  If that VM is vMotioned to a new host, is it normal for the USB to drop connection?  Again to be clear, the USB device is connected to his laptop and the VM is hosted on a server.  The USB is not directly connected to the host.

 

I have not tested this on ESXi 6 yet but I know this is a problem on 5.5.

 

Thanks in advance.
