Access USB on ESXi Host to transfer iso to DataStore

November 19, 2013, 1:54 am

Hi All,

 

I just got Dell Poweredge C1100.

I was able to install ESXi 5.5 via USB as a boot device.

 

Now I want to install some VMs but I have trouble since this server does not come with CDROM and has 100 Mbps NIC cards.

I can connect the USB to guest VM and could access the device after Power On and Attach but that's not enough.

(1) I would like to setup so the client VM the USB as a boot device so can start installing from USB.

(2) The other option would be to transfer ISOs to datastore, but to do that over 100 Mbps NICs is a long process, I thought if I could access the USB on the host itself than I could quickly move ISO from USB to DataStore.

 

Can you provide me directions as to how to accomplish either (1) or (2).

 

Thanks!

network vmotion ??

Hi All,

 

I was reading the new features in network in ESXi 5.1 and found that there is a feature called Network vMotion. I am unable to understand it

 

A VM in vSS if vmotion'd between hosts >> then if I check the network history (under performance) >> I am able to see the network Stats for the VM.

If a VM is in vDS and if vmotion'd between hosts >> then if I check the network history (under performance) >> I am able to see the network Stats for the VM.

 

If the above is true then what is the difference (in terms of network stats during vmotion) in vSS and in vDS.

 

 

 

Thanks in advance

The link below takes me to my license key for ESXi 4.1. The key says it's good for 4.1 or later. Is this the same key I use for ESXi 5.1? I can't find a key for 5.1 on the 5.1 download page. There's no "manual download" button to select and no key in sight.

I know this a super easy question but I have searched this over and over and I just get more and more confused.    So I would love it if someone could help me without pointing me to other posts :-).

 

I'm currently running server 2008 that is running sharepoint on esxi 5.0 (free) and the cpu is spiking to 90 percent every 5mins so I think it's time to increase the cpu performance, What do I set the CPU settings to ? 

 

My hypervisor box is a Lenovo S5500BC with following specs   8 CPU's x 2.399 Ghz  (Intel Xeon E5620 @ 2.40ghz)   My current config is 1 virtual socket and 2 cores per socket.  I also have one windows 7 box that runs on this box too that uses  1 socket and 1 core.  (I can remove this if needed)

 

THANKS!!

Hello All,

 

 

I'm not one to get stuck troubleshooting something
and give up quite easily, but I have been working on the following issue for
quite some time now. I am trying to setup 2 nested ESXi 5.5 host to
familiarize myself with Horizon View. I am having an issue with my
virtual ESXi hosts seeing the same iSCSI storage as
my physical host. I have enabled promiscuous mode on the portgroup that both virtual host are assigned to, but i am still no
able to see the iSCSI storage from the virtual hosts.

 

 

I would like to have the virtual hosts use the
same subnets for management and iSCSI as the physical host if
possible. I am able to connect to both virtual hosts without a problem, I am
just not able to see the iSCSI storage one i setup the iSCSI adapter.

 

 

(Primary Lab) CL1

 

 

2 x physical 5.5 hosts

 

 

1 x vCSA managing these hosts

Hi, everyone,

 

Does vSphere 5.1 support 4K bytes sector volume?

 

I have a 512 bytes sector volume (volume_01), some VMs are running on the volume. Today, I upgrade my Dell Equllogic firmware to v7 (this version support 4k bytes sector volume).

 

I plan to create a new 4k bytes sector volome(volume_02), and migrate the VMs in volume_01 into volume_02. I don't know whether the different kind of volume is a risk factor.

Physical serial port to VM mapping - works fine or not - list of ESXi releases

Physical serial port to VM mapping can be configured at any ESXi release, but what if it doesn't work?

Guest machine will sometimes report the problem with the serial port, other times it won't.

 

To begin, enable in the VM BIOS only the port(s) you actually need.

Then start (Windows) VM and uninstall all serial ports, including ones not present, to exclude any possibility of conflict.

Rescan hardware, only the port you activated in the VM BIOS should show now.

If the serial port still doesn't work, check that the detected port/irq are the same as you set in the BIOS.

 

Still doesn't work? I find out that at some ESXi firmware releases it won't work no matter what I try.

 

Works:

   ESXi 5.5.0 133820

 

Does't work:

   ESXi 5.1.0.update01-1065491

   ESXi 5.5.0 1474528

 

Feel free to contribute or dispute my list.

 

To make Windows (2000, up to 7, at least) show non preset devices in a device manager, set value "1" to system environment variable "DEVMGR_SHOW_NONPRESENT_DEVICES" (without quotes).

Also, in the device manager: View --> Show Hidden Devices

All,

 

We are having one migration in pipeline. Where we have to migrate production application VMs from existing FC-SAN(NetApp,IBM) to new FC-SAN (Hitachi).

Current Infrastructure:- around 1000 of VMs are running on following hardware.

Hardware:- IBM HS21/22 BladeCenter, IBM rackmount server x3650M3,x3850M5

ESXi Version:- 4/4.1

vCenter Version:-4

VM Guest OS: Windows 2000,Windows 2003, Windows 2008, Linux 5.7,Linux 6.1

FC-SAN:- NetApp,IBM

 

New Infrastructure:-

Hardware:- HP BL460c Gen8 Blade

ESXi Version:- 5.1

vCenter Version:-5.1

VM Guest OS: As-IS

FC-SAN:- Hitachi VSP

 

High Level Approach:-

 

We'll built & make ESXi servers ready to host all of these VMs from old hardware & old FC-SAN (IBM ,NetApp)

 

1 Collate Migration Information

 

 

2 Connect VSPs to Legacy Arrays

 

 

 

3 Present Universal volumes to VSP

 

 

 

4 Discover External Volumes in VSP

 

 

 

5 Create and allocate Volumes to Host PiT copies.

 

 

 

6 Prepare & Test Hitachi Shadow Image Horcm configuration files

 

 

 

7 Migration Window Opens

 

8 Check Integrity of existing environment - Shut down hosts

 

 

 

9 Create ‘quick’ Replicas

 

10 Mount and test PiT copies

 

 

 

11 Run Remediation Procedure

 

 

 

12 Migration Window Closes

 

13 Delete Pairs and Disconnect External Volumes.

 

14 Continue to the Next Planned Volume Group

 

 

 

15 Decommission Legacy Storage

Once this storage activity completes then replicated LUNs will be visible to new ESXi 5.1.

What issue /steps needs to be performed to make these VMs up in new infrastructure.

Hello,

 

We have been able to create several vm running different OSX version like Lion (10.7), Mountain Lion (10.8), Mavericks (10.9) and even xServer (10.6) from their iso file.  But it does't worked with Snow Leopard (10.6).  Few second after powering on the vm it goes off by itself.  The iso file that we are using to create this vm was recently purchased for this project and contain all the drivers.

Does anyone have a clue on what could be done to troubleshoot this issue ?

Strange RDP Behavior

Hi all - hoping someone may be able to help me out with an odd issue I am seeing.

 

I have an ESX5.5 server installed which hosts some VMs. Within that server, I have some vSwitches defined which host different subnets. I have a virtual firewall (pfSense) that has a vNIC in each switch to perform routing from my physical router to the vSwitches and between the sites/vSwitches themselves.

 

Everything network wise seems to be working fine internally, all VMs communicate with no drop outs etc.

 

However, when I RDP from my laptop on my physical LAN to any VM, the RDP reconnects quite frequently. It basically hangs and then re-connects in about 15 seconds. I can continuously ping the servers with no drops and the trace route indicates that everything is going the route it should do. I have used this exact config in Hyper-V and do not see this issue.

 

This makes me think I have perhaps misconfigured something in ESX. Has anyone else ever experienced any issues with RDP to VMs in ESX? This is really frustrating me now

 

Thanks for looking.

 

Tom.

ESXi 5.1 on Dell PowerEdge R710

Hi,

 

I'm on task to install ESXi 5.1 on 6 new Dell PowerEdge R710 servers.

 

I downloaded the .iso's for ESXi and vCenter as soon as they became available

but I've recently been told that those .iso's will not work and that I will need to

create custom .iso images loaded with current Dell hardware drivers before I

can proceed with the install.  Is this true?

 

Technically, I was told that a custom installer would need to be created for ESXi 5.0 for Dell PE R720's but would also need

to do the same for 5.1 on R710's.

 

I recently found this .pdf on Dell's support site:  http://support.dell.com/support/edocs/software/eslvmwre/VS_5/Docs/ESXiDG/ESXi5DG.pdf

 

Under Creating the ESXi Installer Media it says to visit support.dell.com to download a custom installer image (.iso) for ESXi

 

I went there, punched in the service tag for one of our new R710's and did indeed find a custom installer image for ESXi 5.1

 

Shouldn't that image contain the required hardware drivers?

 

Any information on this would be appreciated.

 

Thanks!

Whenever I click on Emulex OneCommand tab I am getting "adapter information cannot be fetched from the server cannot proceed further"

Connecting from a window client also shows no adapter on the servers at all.

 

Just curious if anyone is having the same problem I am having and maybe how u solve it ?

Hi Guys,

 

We're trying to test Windows Server 2012 R2 Preview on out vSphere enrionment (Latest 5.1 U1 with updates).
Although it is not supported, we're trying to get it to work.

So:

1. Windows Server 2012 R2 (Hardware version 9) succesfully installed.

2. In order to sysprep, a problematic schedule task is disabled

ESXi 5.1 hosts no longer logging to vmkernel/vmkwarning logs?

I have 6 hosts all configured with the same syslog configuration:

 

   Local Log Output: /scratch/log

   Local Logging Default Rotation Size: 1024

   Local Logging Default Rotations: 8

   Log To Unique Subdirectory: false

   Remote Host: tcp://server.domain.com:514

 

Two of the 6 hosts no longer write to the vmkernel and vmkwarning logs locally for some reason.  They do write to other logs like syslog, vobd, vpxa, etc.  They are writing to the syslog server configured in Remote Host.  I've already tried reloading syslog via Powershell and from the console to no avail.  I've torn out the syslog server config and restarted and still doesn't log.  Are these vmk* logs separate from syslog?  Any ideas?

 

EDIT:  I should also add that it is not a disk space issue as other logs are being written to appropriately.

In a nutshell I increased the the LUN on the SAN to 3TB (let's call it A) and I'm now told that VMFS 5.54 only supports up to 2TB, so the question is, in my frantic state how would I get things back to the way it was (in that A is getting full and why I'm here now trying to reclaim the space on the SAN to give to another 2TB LUN), seamlessly and without interruptions (is that possible?), bear in mind we are running vSphere 5 Essentials Plus so no storage vMotion and please forgive my ignorance...

 

1. create a new 2TB LUN (B)

2. shutdown VMs on A

3. move the contents of the 3TB LUN (A) datastore to the above newly created LUN (B) datastore

4. destroy the 3TB (A)

5. create another 2TB LUN (C) to use as we needed more space to begin with...

5. tada? does that make sense? I'm thinking straight and any help would be greatly appreciated.

Change in checkpoint resume IO behavior between ESXi 5.0 and 5.5?

February 13, 2014, 12:41 pm
$
0

I've noticed something very interesting in migrating to ESXi 5.5 from 5.0. The short version is that it appears on 5.5, if your VM has IOPS limits on it (via througputCap), those limits affect reading the checkpoint file. Lower IOPS means longer resumes.

 

In 5.0 this doesn't seem to be the case, or at least something was different enough that we didn't see long resume times.

 

Some background: All our VMs are on NFS shares that we mount to the ESXi host prior to resuming them.

 

We're aware of this KB article ("ESXi does not apply bandwidth and throughput limits when both are configured for a SCSI virtual disk in the configuration file of a virtual machine (2059192)". However, it doesn't seem to apply to us as we're not using "bandwidthCap". Also, our problem isn't that IOPs aren't being limited; rather they're being limited at an inopportune time. Also, for what it's worth, our hosts are running with the "old" scheduler (non-mclock) as mentioned in that article. We had serious perf problems with the mclock scheduler enabled.

 

I also did notice something interesting in the logs. On all of our 5.0 resumes, we had a line like this, where pshared is always non-zero.

 

vmkernel: cpu0:3602473)Swap: vm 3565602: 14222: Finish swapping in checkpoint file. (faulted 511896 pages, pshared 336968 pages). Success.

 

On 5.5, all of our resumes have a similar line, but pshared is always '0':

 

vmkernel: cpu11:548952)Swap: vm 548944: 3922: Finish swapping in checkpoint file. (faulted 261731 pages, pshared 0 pages). Success

 

Given my background in OS development, this seems significant. However, I can't find any relevant documentation on what "pshared" means in this exact context, nor find any settings in 5.5 that might affect it's behavior.

 

Ultimately, the big issue is getting back to our speedy resumes. The pshared bit may be unrelated, but throwing it out there in case it helps trigger an idea from somebody.

 

Thanks,

 

Matt
