vt-d enabled Ivy Bridge motherboard recommendations

I'm finding it difficult to find solid information about vt-d support on IB boards and was hoping the community could confirm/deny support on the current offerings.

 

The only manufactuer I've seen that claims support on any of their boards is ASRock; the manuals for the majority of their lineup mention it in passing.

 

I found this forum post which seems to indicate GIGABYTE is working on vt-d support and offer beta BIOS versions to enable it at your own peril: http://forums.tweaktown.com/gigabyte/48493-x58a-ud7-rev1-vt-d.html

 

As for ASUS, they seem to be claiming that vt-d support on newer chipsets is "impossible due to hardware limitations". Some useful information can be found on this forum: http://hardforum.com/showthread.php?t=1688360&page=6

The ASUS rep indicates that only Q-series chipsets were validated by Intel to be fully vt-d capable. Apparently ASUS is having trouble passing Intel's vt-d conformance test suite, which leads me to question whether or not ASRock is being disingenuous about their claim to support vt-d; evidently at least some people have had success with ASRock's boards, however.

 

Aside from motherboards, if anyone can offer advice on setting up VGA passthrough under ESXi, I'd be very appreciative. I know this isn't an officially supported feature, but it seems others have gotten it to work, and I'm willing to put in the time to make it work for me. I've heard various reports that nVidia cards are no good for this, but all I have right now is a GTX 460. I'd like not to have to buy a new card unless necessary; can anyone out there report success with this card and/or other nVidia cards?

We have a VERY old HP UX system (version 10).  We still use it as a production server and are afraid of a hardware failure.  What is the process to convert something like this to a VM?  I am using ESXi free right now.  Thanks!

ESXi 5 VLAN VST mode configuration issue

Hi, im trying to configure 2 vlans 1600 and 1601 for 2 vms

it works fine in VGT mode on portgroup with VLAN ID 4095

 

here is the config:

Untitled.png

 

But i think it would be much better to use VST mode because i have only 2 vlans and access to all vlan range is unnecessary

 

the configuration for VST is

Untitled.jpg

But it doesnt work at all, my vms cant ping their default routers and each other

 

Configrutaion:

ESXi 5 Server

 

1 port on a physical switch set in trunk mod with standard IEEE 802.1Q for VLANS 1600 and 1601 (both vlan subnets with 25 prefix length)

100Mbit full duplex auto negotiate

 

2 VMs with Linux RHLE 5.8

NIC teaming on bond0 and vlan interfaces bond0.1600 and bond0.1601

cxgb3i network driver with 8021q module

 

How can i resolve this issue?

 

Best regards

Hi Everyone,

 

Having a bit of a strange issue with vMotion today.  It's been working in my lab for months, and was still working fine after I upgraded to 5.1 last week.

 

Now, today, for whatever reason, it just refuses to progress beyond 14%, failing with timeout.  Here's the log snippet:

round-trip min/avg/max = 0.122/0.138/0.162 ms

 

 

I've tried restarting vCenter itself, no help.  Tried multiple different VMs.  Tried various combinations of my 4 hosts, and none of them work.

 

I just dont know where else to go - Ideas?

 

Edit:  Other things I've confirmed:  Time sync is good.  Disk free space is good.  FWD and REV name resolution is good.

Please spare me how I shouldn't be using the oboard NIC for anything on a server.  Anyway, I'm wondering if there are some drivers I can load that would allow me to use the onboard NICs on the PowerEdge t420 or if I'm SOL.  When I boot into esxi it tells me that there are no recognizable network adapters on the system.

Datastore partition table corrupt or missing on ESXi 5.1

I assume the yellow highlighting means that my partition table is jacked.

 

partedUtil get /dev/disks/naa.600605b0008753401647ba843bf15150
364485 255 63 5855465472

 

Original partition was a single VMFS 3 partition that had been upgraded to VMFS 5

 

ESXi is installed on a USB Key

 

This problem occurred when I shutdown all of my VMs, shut down the machine nicely and remove a datastore worth of drives from the raid controller and replaced them with new drives.  I configured the new raid 10 array and upon bootup all of my VMS are gone.  Obviously I missed some step which was likely that I needed to delete the data store first.

 

 

Please advise as I need this back on line soon.

/bootbank/boot.cfg question(s)

Let's say I have a customized .vgz file the contains some information (files) that normally wouldn't persist across reboots. I move the "customized.vgz" file to "/bootbank". Then I believe I need to modify the boot.cfg file's boot options.

 

If this is correct, could someone please post an example of what the boot.cfg file contents "might" look like concerning a "boot options" line/entry? I'm interested (primarily) in syntax and format.

 

 

Thx.

ESX5.0 Windows 2008R2 VM Hangs

January 14, 2013, 9:11 am

We recently deployed a Windows 2008 R2 VM in our environment. The server is also running Microsoft SQL and Microsoft SCCM. We have noticed that the server tends to hang or freeze every couple of days with no explanation. During the times it hangs, RDP is unavailable (hangs after accepting credentials), and the SCCM console (the whole purpose of this server) hangs as well. However, an inspection of resources (both inside Windows and in the VM enviroment) shows very little useage of memory or processor. The server also responds to pings and is very slow if a Windows session was already open. The only fix for the hang is to reboot the VM, OR to migrate the VM to a different ESX server. As soon as the migration is complete the VM is quickly active and responds as normal.

 

In our environment we have ESX5.0 cluster with 5 physical HP Blade servers (running HA) and attached to an HP 6000 SAN. We've been in this configuration for quite some time and run approximately 30 VM servers (mix of Windows 2003 and Windows 2008) with no performance problems. During peak times only 4 of the 5 ESX servers are actually running so I believe we are pretty efficient. During the times the server in question hangs, no other VM's appear to be affected and everything seems normal in the ESX cluster.

 

I've seen a few forum questions that were similar and related to video drivers, but that doesn't seem to be the issue here since the VM is running standard Microsoft display drivers. The VM is also running the latest compatible VMTools (8.6.5).

 

Any thoughts or suggestions as to what might be causing this hang? Thanks in advance for any assistance.

Active Monitoring VMWare ESXi Host

Hi all,

 

I want to monitor a VMWare ESXi Host in a active manner. In other words, I want that this host send performance informations to my monitor machine instead of my monitor machine ask for these informations. In Xen I can put a script or a Java application to run at Domain0, but in VMWare ESXi this seems to be impossible. Is there a way to do this?

 

Thank you all!

Local Storage Question

Is there a way for me to determine how the local storage on one of my ESXi5 hosts was configured / allocated? I have one HP DL host that has 8 local 146 gig drives and I have a need to re-create the identical config.

 

I did not setup the host so I'm not sure how the space was split up. I'm pretty sure it was setup RAID 5 with one spare drive, but that's about it.

 

The host is online and I can not reboot / take it offline to review with HP SMart Start.

 

Ideas?

 

Thanks

HP Flex 10 - Received Dropped Packets

VMware Community,

 

We are having a strange issue, which so far VMware/HP support has not been able to solve.

 

We have an environment where we are using 2 x 10GBps and 2 x 9Gbps adapters on a single DVS.

 

The DVS supports ESxi Management, vMotion, and Data traffic for the VMs.

 

We have Resource allocation turned on as well.

 

The blades are G7s.

 

Our problem is we are constantly seeing dropped received packets in this cluster. After a lot of research we thought it may be firmware/driver related and went down a whole path of updating our chassis, hosts, drivers, etc to the latest supported config by HP.

 

Still we are getting dropped received packets. We can recreate it quite easily, by initiating a vMotion.

 

We've tried running on just the 2 x 10gig and just the 2 x 9gig adapters but this made no difference.

 

Anyone got any suggestions?

ESXi 5.0 & DELL R720 Network Connectivity Loss

September 3, 2012, 11:41 pm

Ok there have been a lot of threads about trying to get the Dell R720 working with the Broadcom 5720 daughter card.  You can inject the drivers post build or you use the DELL recovery cd http://ftp.dell.com/FOLDER00609866M/1/ to build the server.

 

The problem I am highlighting in this post occurs when the servers are commissioned.  We put 4 DELL R720 servers in production.  They are configured using 4 ports on the 5720 etherchannelled and using vDs. Within 2-3 weeks at different times all 4 hosts experienced a network failure and caused production outages.  All Vm's were unresponsive & offline and a reboot of each physical host resolved the issues temporarily but would reoccur at a later date.  Calls to both vmware and Dell were not very productive and it took 2 months to finally work out the problem, involving a lot of time & effort on my part.  Basically specific to the DELL R720 server the below criteria must be enforced to ensure the hosts do not experience random network loss.

 

 

The above was implemented on all 4 hosts they have been stable for the last 8 weeks.

USB Boot - Logging to Datastore

January 14, 2013, 1:56 pm
$

We recently upgraded to ESXi 5.0 U1 and are utilizing booting to USB.  For this reason, we have chosen to have our logs redirected to a datastore on our SAN.  My understanding was that all we needed to configure to do this is the setting for 'ScratchConfig.ConfiguredScratchLocation' under "Advanced Settings -> ScratchConfig".

 

I realized that there are still events being logged actively to the USB in /var/log/.  From what I am reading, to stop this you need to configure 'Syslog.global.logDir' to point to a datastore also.  I've done this, and cleared out all logs from the local /var/log/, and I don't see anything coming back there.

 

But, I have both of these settings configured to the same directory on our SAN.  They have to be in different formats, but they both point to the same location.  Is that OK to do?  I'm assuming they are all the same logs so it should be OK, but I just wanted to verify with someone who knows about this first.

Variations on this question are asked fairly often, but I'd like to get further clarification for my scenario.

 

I have an ESXi 5.1 test server with a single i7-3720QM processor, with 4 cores, and 8 logical processors.

 

Considering only two (2) Windows Server VM's will ever run full time on this server, how many total CPU cores should I assign to each for MAXIMUM performance? 2, 4, or 8?

How to retrieve data returned by a target using vmk apis?

I am a newbie to VMWare plug-in development. I have written code to issue a SCSI READ 10 command to a target. After allocating memory for all the variables, I am calling vmk_CreateSCSICommand() to give me a scratch SCSI command. I then change the CDB based on the LBA I want to read and the bytes I want to read. I am using vmk_ScsiIssueAsynchPathCommand() to issue the command to the target. On the target side, I can see the read come in, and the data go out and successful status is returned to the initiator. I see the ->done callback that I set when I sent the command out being called by the VMKernel. However, how do I get the actual data that is returned by the target? I have the vmk_ScsiCommand structure available to me, but I do not see any way to get the data.

Any help on this by the guru's will be appreciated.

Thanks

Deploying OVF Template in ESXi v5.1

Hello All,

 

I am trying to deploy an OVF template that was created from a Windows XP SP3 VM in VMWare Workstation v9.0.1 to an vSphere Hypervisor (ESXi) v5.1 located on a Dell Poweredge server.

 

Every time I attempt to deploy the OVF template, the deployment errors with the same message - "Failed to deploy OVF package: A specified parameter was not correct."

 

The VM is a v6.5 - v7 hardware configuration. Could this be the problem? Do I need to upgrade it to a v8 hardware configuration?

 

All three disk format options (Thick provisioned Eager and Lazy Zeroed and Thin provisioned) all fail with the same message however the Eager Zeroed seems to 'run' longer than the other options which fail almost immediatedly.

 

I am not sure what I am doing wrong.

 

Any help would be appreciated.

 

Thank you.

Couldn't shrink vmdk with converter

I've red a lot of posts on how shrink a vmdk, but I don't know how to proceed. I have a 450GB vmdk containing only 40GB, ESXi 5.0 U2 and 2 datastore (500GB + 250GB). So this is what i've done:

 

  1. i've zeroed all the free space on the OS filesystem
  2. i've used 'vmkfstools --punchzero <src.vmdk>' to remove zeroed free space, now its size is 40GB (obtained with 'du -sh <path/*.vmdk>')
  3. i've moved it from datastore2 to datastore1 using 'vmkfstools -i <src.vmdk> <dst.vmdk> -d thin'
  4. i've repartitioned the filesystem from 450GB to 64GB

 

Now, what I want to do is to resize the thin provisioning of the vmdk, in order just to fit 64GB, and i've tried to do with Converter. The problem is that at the end of the conversion wizard, i can't select nothing else than option "copy all disks and maintain layout"

 

converter_prb.png

 

Of course this is not what I was expecting... but i don't know how to solve this problem.

Anyone can help me please?

 

Thank you,
