Hello All,

 

I am not an expert in Vmware, kindly bear with me.

The customer is trying to deploy OVA of our application which is packaged into Ubuntu 14.04. Our application requires VT-X and EPT technologies also required nested virtualization.

The OVA is deployed in UCS-C240_M35, ESXI 6.0 and a cluster in which has EVC enabled and runs on EVC mode Penryn. when we power on the VM we get the following error.

We also get the following error while trying to migrate.

The Host CPU Intel Xeon E5-2680 supports VT-x and EPT, so there is no reason for that error to pop in. Will EVC limit the VTX capabilities running in EVC mode Penyrn?

 

Thanks in Advance,

Romal

Hi guys,

  could you help me please run ESXi 6 under Ubuntu 14.04.04  with kvm-qemu.

 

I have   Ubuntu 14.04.4 LTS

             ESX  6.0   vmware-201601001-3380124-iso

             Running hypervisor: QEMU 2.4.0

 

I try to run VM on EXSi  which running under KVM.  

So, ESXi was successfull installed,  the command in ps :

qemu-system-x86_64 -enable-kvm -name esx -S -machine pc-i440fx-2.4,accel=kvm,usb=off -cpu Nehalem,+invpcid,+vmx -m 8096 -realtime mlock=off -smp 4,sockets=4,cores=1,threads=1 -uuid b2c3b37b-9596-98ab-8e0d-f05df89d2920 -no-user-config -nodefaults -chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/esx.monitor,server,nowait -mon chardev=charmonitor,id=monitor,mode=control -rtc base=utc -no-shutdown -boot strict=on -device piix3-usb-uhci,id=usb,bus=pci.0,addr=0x1.0x2 -drive file=/var/lib/libvirt/images/esx-20.img,if=none,id=drive-ide0-0-0,format=raw -device ide-hd,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0,bootindex=1 -drive if=none,id=drive-ide0-1-0,readonly=on,format=raw -device ide-cd,bus=ide.1,unit=0,drive=drive-ide0-1-0,id=ide0-1-0 -netdev tap,fd=26,id=hostnet0 -device e1000,netdev=hostnet0,id=net0,mac=52:54:00:96:74:1c,bus=pci.0,addr=0x3 -chardev pty,id=charserial0 -device isa-serial,chardev=charserial0,id=serial0 -vnc 0.0.0.0:0 -device cirrus-vga,id=video0,bus=pci.0,addr=0x2 -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x4

 

But I always get error like :

Virtualized INtel VT-x/EPT is not supported on this platform. Continure without virtualized msg.intel.hvhwmmu? during starting VM on ESXi

 

cat /proc/cpuinfo  on 0 host machine

Nested ESXi 6u2 Host on VMware Workstation v12 for Linux Network Problems

May 28, 2016, 5:12 pm
$
0
0

I Hello everyone,

 

I have a virtual lab environment running in VMware Workstation v12 for Linux, and my ESXi hosts are not working properly on one of the virtual networks. All of my troubleshooting suggests an issue with the nested ESXi hosts that may be a bug of some sort, but I want to make sure that I have done everything correctly first. That is why I'm posting here with the hope that if I did make a mistake that perhaps someone else can point it out to me.

 

Physical System

8 core Intel Xeon 2.1GHz CPU

128 GB of RAM

OS - Linux Mint 17.3 64-bit w/3.19.0-32-generic Linux kernel (fully updated as of this posting)

VMware Workstation 12 Pro - 12.1.1. build-3770994 (fully updated as of this posting)

 

Nested ESXi Host VM

ESXi v6.0.0 (Build 3825889, fully update as of this posting)

4 "physical" NICs (only 3 being used for now)

    - all use e1000 NIC virtual hardware, but also tried vmxnet3 NICs with no difference

    - vSwitch0 uses vmnic0 & 1 on virtual network vmnet16 in an active/standby pair

    - vSwitch1 uses vmnic2 on virtual network vmnet18

    - vmk0 used for management on vSwitch0, and vmk1 to be used for iSCSI on vSwitch1

    - promiscuous mode and forged transmits enabled on all vSwitch Port Groups (enabling or disabling these features makes no difference)

 

Testing Done So Far

I have verified that all IP adresses and netmasks being used are correct.

Using vmkping I have pinged other nodes on the vmnet16 network successfully.

Using vmkping I have attempted to ping other nodes on the vmnet18 network, but that has been unsuccessful.

I have depolyed other non-ESXi VMs onto the vmnet18 network, and they are able to ping each other but are unable to ping or be pinged by the ESXI host.

I have tried various virtual hardware NICs as mentioned before, but with no changes in results.

I have tried using LAN segments instead of the host-only network vmnet18 with no changes in results.

 

When I view the state of the ESXi host's NICs via vCenter or the embedded host client vmnic0 & 1 both show network information, but vmnic2 shows no networks. Yet I know that there is a network with various VMs communicating on it. Furthermore I was able to get all of this working on a Windows system running Workstation 10 (this is the laptop that my employer provides me with).

 

Having built working nested ESXi labs on various platforms as well as physical environments in the past I'm very confused as to why I can't get this particular setup to work. At this point my gut tells me that it is probably a bug of some sort with the nested ESXi hosts themselves. Since I can get everything working on vmnet16 including the ESXi host management and the VCSA that I am using I am certain that my vSwitch configuration is correct (other than IP space and vmnics the configurations are bascially identical). Since I can get other VMs to communicate over the vmnet18 network I do not see how this can be a VMware Workstation of Linux physical host issue. Is there something obvious that I am missing here? I have read about nested ESXi hosts running on VMware Workstation having known issues and bugs with networking. Has anyone else encountered this?

 

Thanks for any help that others can provide!

 

Regards,

 

Patrick

These two days I'm install ESXi in Workstation Pro 12.

 

(1) create VM in workstation, 4x cpu, 16GB member, create 100GB SATA harddrive, select OS ESXi 6.0, connect virtual CD to ESXi 6.0U2 iso file.

(2) Power on this VM to install ESXi ,  during the installation,  the installer cannot detect any SATA hard drive, so cannot proceed.

 

if I change the Hard drive type to SCSI, the installation has no problem,  installation and running is smooth, nested VM in ESXi also have no problem.

 

Any hints or idea?

 

I have tried to add the following to workstation vmx file, but no hlep

 

sata0.present = "TRUE"

sata0.virtualDev = "ahci"

 

sched.sata0:0.shares = "normal"
sched.sata0:1.shares = "normal"
sched.sata0:2.shares = "normal"
sched.sata0:3.shares = "normal"
sched.sata0:4.shares = "normal"

sched.sata0:0.throughputCap = "off"
sched.sata0:1.throughputCap = "off"
sched.sata0:2.throughputCap = "off"
sched.sata0:3.throughputCap = "off"
sched.sata0:4.throughputCap = "off"

VLANs in Nested ESXi Servers

November 7, 2016, 9:51 am
$
0

In my lab environment, I have an ESXi 6 host and 2 ESXi 6 nested servers that are working with VLANs set up on a physical switch.

 

Host vSwitch is configured on VLAN 4095 for vmKernel and VM port group.

Nested Guest #1 has its vSwitch configured on VLAN 4095 for vmKernel, and I have multiple port groups for the various VLANs that are configured on the physical switch. (180-Management, 181-Application, 196-Provisioning, etc.)

Nested Guest #1 and Guest #2 has its vSwitch configured on VLAN 4095 for vmKernel, and I have multiple port groups for the various VLANs that are configured on the physical switch. (280-Management, 281-Application, 296-Provisioning, etc.)

 

Here is the hurdle I am having difficulty getting over. I need to set up 6 more servers just like this one with the same VLAN configuration connected to he same switch. Since you cannot have duplicate VLAN numbers in the same physical switch, I am looking for suggestions.

 

Is it possible to not have the VLANs configured in the physical switch and use virtual switches or an appliance to simulate the physical switch?

 

Really would appreciate any suggestions.

Nested vmware workstation on KVM host

I am trying to run an instance of vmware workstation on top of KVM.

 

First problem related to "incompatible hypervisor", which I fixed by adding "vmx.allowNested=True" in the .vmx file

This is apparently something I need to put in all my .vmx files.

 

Question 1: can I set some default value to allow nesting?

 

Second problem:

 

When I start a 64 bit virtual machine, I get

"Binary translation is incompatible with long mode on this platform. Long mode will be disabled in this virtual environment and applications requiring long mode will not function properly as a result. See http://vmware.com/info?id=152 for more details."

 

If I click ok to that I get

"This virtual machine is configured for 64-bit guest operating systems. However, 64-bit operation is not possible.

This host supports Intel VT-x, but the Intel VT-x implementation is incompatible with VMware Workstation.

For more detailed information, see http://vmware.com/info?id=152."

 

I have tested with KVM on the same virtual machine, and it has no problem running the same type of virtual machine. My test machine a new machine with the debian 8 installer in the "CD" drive,

 

Question 2:

How can I make this work?

Do you have any hints, links, references, examples or such that might help me?

 

Versions

- host is debian 8

- virtual machine is also debian 8

- vmware workstation pro 12.5

Hi,

 

Has any one successfully installed Citrix XenServer 7 as a VM on top of ESXi 5.5?

I encountered hardware Dom0 crash during installation.  I have tried various tricks without any luck. 

I know I am not the only one who encounter this problem.  Someone was able to install XenServer 7 as a VM on top of ESXi 6 (Cant install XENSERVER 7 on esxi 5.5 - Server Installation - Discussions).

 

I was able to install Citrix XenServer 6.5 as a VM on top of ESXi 5.5, and also run VMs inside of XenServer 6.5.

 

Thanks for any tips.

OpenStack (KVM/QEMU) in vSphere - Occasionally segfaults occurring in OpenStack VMs with more than one vCPU configured

January 18, 2017, 12:48 am
$
0
0

I am running OpenStack Newton as HA deployment on Ubuntu 16.04 vSphere VMs in conjuntion with a Ceph Storage (Jewel). The deployment comprises:

  • 2 controller VMs
  • 3 compute VMs
  • 3 storage VMs

Everything is up and running. There are no configuration issues known regarding the OpenStack environment. The same setup is working properly on "real" hardware-based machines.

 

Unfortunately, I am confronted with segfaults occasionally occurring at startup of my OpenStack VMs (tested with Ubuntu 14.04/16.04). These segfaults appear randomly in different Ubuntu services, unforeseeable where and when. Theses faults are definitely not software-related and appear only when OpenStack VMs are configured with more than 1 vCPU. The probability to create a broken OpenStack VM rises with the vCPU count which means segfaults occur more frequently in an OpenStack VM with 4 vCPUs than in one VM with only 2 vCPUs configured and never happen in VMs with only 1 vCPU. I was able to spawn and destroy 500 VMs successfully in series using only 1 vCPU.

 

I am using KVM/QEMU as hypervisor on my compute nodes, so there must be a problem when running KVM on ESXi-based nodes. Hardware virtualization support is activated for my vSphere VMs:

$ egrep -c '(vmx|svm)' /proc/cpuinfo

4

$ kvm-ok

INFO: /dev/kvm exists

KVM acceleration can be used


I have also tested using a different clock source for my vSphere VMs and switched from tsc to acpi_pm, but the issue is still occurring when more than 1 vCPU is configured in my OpenStack VMs. All OpenStack guest VMs use kvm-clock as clock source.


The problem must be related with ESXi, because KVM on real hardware works without any issues independently of how many vCPUs are configured for an OpenStack VM.


Any hints what to do?

KVM on ESXi causes segmentation faults in guest VMs with more than one vCPU

This post is related to this one:

OpenStack (KVM/QEMU) in vSphere - Occasionally segfaults occurring in OpenStack VMs with more than one vCPU configured

 

I was able to narrow down the problem described above. I have setup a vSphere VM based on Ubuntu 16.04 and installed KVM. I defined several guest VMs based on different Linux operating systems. When you add more than one vCPU to one  KVM guest VM, you occasionally receive segmentation faults in different processes unforeseeable where and when. The probability increases when you add more vCPUs and when the hosting machine is under high load.

 

I know that nested virtualization is not officially support, but we are so close. The scenario can be reproduced easily.

 

Is someone out there, who can support me getting KVM properly running?

Jens

VM player runs smoothly in 5 years old PC, but super slow in an alienware laptop

I tested a few VMware player created vm, all hosting ubuntu, 12.04, 14.04 and 16.04. They all works smoothly in 5 years old PC, embarrassed to mention its specs. The confusing fact is that none of them works well in a new alienware 15R3 laptop, 16GB memory, SSD, Nvidia 1070 graphic card. Even a text editor needs wait time of a few second to tens of seconds to refresh the view.

Linux tool update has been conducted in the vm running in the new laptop. Before than after the update, no difference. This upgrade was not conducted in the old desktop and it runs smoothly.

8GB RAM allocation in the new laptop, 2 GB is more than enough, which has tested in the old desktop.

Disk defragmentation in windows has been conducted.

The VM ware player data file is one big file instead of spreading into multiple smaller files.

The VM ware player data file is stored in SSD drive.

Any suggestions?

Hi guys
I request some suggestion on pc system setup in my office

we currently have a setup of 5 pc's connected by a single server over a ethernet switch

but soon business is expanding and i need a better IT infrastructure
with around 12 system  and couple of laptops all will be connected ,

 

How can VMWARE be usefull to my organisation , and which software,

initially i was going to buy 3 servers, but after coming accross vmware i think i dont need that

i need some sort of security as well, so that my employees have only .limited access to the system,

 

1-I run Autocad on 3 systems

2-is Thin Client a good idea to implement
as i am looking for a secure sytem, where user access is limited to read only files

3-or a simple 12 desktop systems and network it the way it is ,

Suggestion would be helpfull

Any ITIL people out there?  I'm wondering how many folks we get on the site who are focused on ITIL v3, or specific topics like Capacity Management?

 

If you're not ITIL focused - is there someone in your org that is?  Would they benefit from some proven practices that show how things change with virtualization?  Why not send them a link to VIOPS and get them involved?

 

We already started a couple of these..  The specified item was not found.

 

We could add a lot more... but only if folks are interested...

Please vote, and pass comments on this poll.  In VMware we have built up quite a bit of knowledge over the years on the impact of virtualization on ITIL processes - it's not everyone's cup of tea, but ITIL seems to be more ubiquitous these days, especially in large or governmental organizations.

 

The results so far show 93% say yes, whilst the other 7% think this is more applicable to someone else in their organization - who are those people, how do we get them on VIOPS?
