Re: Testing VMWare ESXi under Virtual Box

The file you requested is attached.

 

Just as an additional data point, I exported the VM from VirtualBox, and started it using VMWare Player, and I then successfully created and started a VM using this method. I'd still like to get it working in VirtualBox if at all possible.

I think ESXi running under VirtualBox is probably just a curiousity.  You'll be limited to running 32-bit nested VMs with binary translation, and the overhead of shadow paging in the guest hypervisor is going to result in abysmal performance.  But I'll see what I can do to help.

 

The core file indicates that the syscall instruction resulted in an illegal opcode exception.  The most likely explanation is that EFER.SCE went clear.  However, I'm not sure how that might have happened, and the current EFER value isn't in the core file.  Can you also upload the vmmcores.gz file?

Agreed, I only want to run ESXi inside a VM for evaluation purposes. Just need to satisfy myself it could replace my XCP box.

 

Particularly interested in whether I can convert the existing XCP VMs over to ESXi. 64 bit could be an issue there, as all my existing VMs are 64 bit. Will VMWare player allow me to create 64 VMs on an ESXi instance running within VMWare player?

 

Will upload the file you asked for in the morning.

 

Thanks again.

Yes.  You will have to enable virtualized hardware-assisted virtualization to run nested 64-bit VMs.  See Running Nested VMs.  It's not a very good way of evaluating ESXi, but it's far better than running ESXi under VirtualBox.

OK, sounds like this maybe the way forward. I'm particularly interested in the conversion process for getting my current XCP VMs over to ESXi. I would want this to be as painless as possible, so want to verify that this is the case before going ahead with the move.

 

Thanks again for the help.

That's a great script, thank you!  You seem to know exactly what I'm looking to do.

 

I'm relatively new to the scripting, I've written ones for changing all the root passwords, changing notifications, that kind of thing.  A few questions from this snippet:

 

$SourceVM = "DAServer" 

$DestinationVM = "DAServer_Clone" 

$DestinationHost = "mini2.vcaplab.local" 

$DestinationDS = "SSD" 

$SourceVMName = Get-VM -name $SourceVM 

$DestVMName = Get-VM -name $DestinationVM 

if (!$DestVMname) 

{ 

#VM Does not exist, create the new clone 

New-VM -Name $DestinationVM -VM $SourceVMName -VMHost $DestinationHost -Datastore $DestinationDS 

$DestVMName = Get-VM -name $DestinationVM 

 

Since we are cloning from one host to another, the $DestinationVM and $DestinationHost variables make sense.  I see $SourceVM as the source VM but where do you specify the host that holds that source VM? 

 

Thanks so much for your help, this is just what the doctor ordered and something I"ll dig into right away!

One of guest OS is utilizing 99% cpu.

Are you seeing this value from esxtop or from inside the guest?

 

Any detail abt ESXi version, guest details, vmware tools details would be highly helpful

after one or more days it isn't more active. so i look in the vSphere Client -> its not active.

So from vSphere client, it says tools not running, if I am understanding it correctly?

 

When i will connect via SSH to my VM, i can't create a connection and when this problem is coming, all services of the VM are unavailable after a time.

Looks like apart from tools the processes are either killed by kernel or not started either due to memory crunch or simply they are unable to be started. Can you let us know, if you are using a vmxnet3 or e1000 driver?

 

At this point, I am slightly inclined to say that either the server or the VM is heavily under pressure. I have seen this in my setup.

While performance validation has not been mine strongest topic, I do notice that "3D Studio Max" would in turn utilize a huge amount of graphics calls. Now, my focus would be the supportability of the heavy graphics in virtual machines rather than NUMA/Core affinity allocation.

Unable to format Esxi5.0 & install Esxi5.1

Hi All,

 

I need to format an ESXi5.0 blade server & install ESXi5.1 on the same blade (new setup) - boot from CD.

 

Issue:

 

unable to boot from CD to install new Esxi5.1 as the existing installed ESXi5.0 reloads instead.

 

Already checked:

 

- boot media/CD which is working fine - tested on a brand new server

- checked the boot order to be on CD

- can boot via a windows server CD for the purpose of erasing the config. However, unable to format the disk as it appeared to be not available.

 

Any help would be greatly appreciated.

 

Thanks

Hello,

 

you have to use VMware converter to reduce the VMDK size, it needs a brief downtime.

Well, than it is more problem of Windows. If VM is loading cpu to 99%, ESXi can not do a lot with it...

 

BTW svchost.exe is what MS calls "generic" process. It loads a few dlls and covers a many functions/services. You should have at least few of them running. It is not easy to find *what* exactly service is causing this load. But I give you a tip:

 

Open TaskManager, click on "Processes" tab, and do not forget to select "Show processes from all users". Then go to menu-option "View" -> "Select column", and activate "Command line". Then check which svchost.exe is causing problem, and have a look at its "command line" (the way it was started). You will see something like:

C:\Windows\system32\svchost.exe -k netsvcs (or dcomlaunch, regsvc, etc)

 

Then you will know which service (served by generic process svchost.exe) is causing problems...

Hi folks,

 

We have been bought new servers

 

old servers has vmware esxi 5.0

 

now i want to upgrade them when migrating to new servers, is it enough to re-register old vm's to inventory on new 5.5 esxi hardware ?

 

thanks for your replies

You can interactively upgrade the hosts using the CD-ROM without the need to re-register. In case the hosts are managed through vCenter Server, make sure you upgrade vCenter Server prior to upgrading the hosts. Also make sure the hosts are supported for the new version and also consider to upgrade the firmware.

1. I suppose your iSCSI vmkernel NIC and the storage are on the same subnet? Please also provide the output of:

esxcli network ip interface ipv4 get

esxcli network ip route ipv4 list

 

2. Can you ping the host on it's own iSCSI vmkernel IP?

 

3. There also used to be some issues with interface selection of vmkping in the past if I remember correctly, try this instead of vmkping:

esxcli network diag ping --df --interface vmk1 --ipv4 --size 8972 --host 192.168.100.50


4. Also make sure you're running a recent NIC driver and NIC firmware on your host. I also have some hosts with BCM57810-based (HP-branded) 10Gbe NICs and jumbo frames running fine with the recent bnx2x driver version 1.78.27.v50.1 and firmware 7.8.79:

ethtool -i vmnic1
