Re: About host memory - does maxing = crashing?

July 19, 2017, 2:50 pm

Hello,

 

Short answer - No, this is extremely unlikely (VMs would likely hang or crash a long time before this could happen).

 

ESXi hosts use a multitude of methods to allow over-provisioning of memory to VMs above the physical memory including:

- Memory sharing (as similar workload/Guest OS VMs will have an amount of identical data).

- Ballooning (reclaiming least used memory from VMs using VMware Tools provided this is installed on the VM).

- Memory compression (as it is faster to compress and read than read from disk if it were have to resort to swapping).

- Swapping (swapping out memory to disk into the main .vswp file of the VM, this is a last resort and impcacts performance).

p27-44 of this explains all of these concepts better:

https://docs.vmware.com/en/VMware-vSphere/6.0/vsphere-esxi-vcenter-server-601-resource-management-guide.pdf

 

More info:

https://docs.vmware.com/en/VMware-vSphere/5.5/com.vmware.vsphere.resmgmt.doc/GUID-9D2D0E45-D741-476F-8DB1-F737839C2108.html

 

You can likely use more than 60GB here but VM performance may impacted as it has to use the more aggressive methods.

(check if/how much you are have as memory reservation for VMs as this can end up reserved and will not be reclaimed using some of the above methods, check that VMs have VMware Tools installed).

DL380 G7 stuck loading at vmkibft loaded

Hi,

 

I have an old DL380 G7 on which I have run an SPP update from April this year, and runs Bios P67.

This model is listed on the HCL for old version like 5.0 and 5.5, including 6.0 plus updates.

 

I have installed on a USB key and am trying to boot (same happens for the installer), but the boot just gets stuck on "vmkibft loaded successfully"

 

Am at a loss on why this is getting stuck here, and looking for some guidance.

Have also tried ensuring the inbuilt raid controller has no default volumes set for boot.

 

Cheers

James

Re: CloudClient with global properties and property groups

Ok, well I guess that answers that question.  I've been googling the answer for a couple of days now.  And now I see there are none.  Well here goes the honorable task of schlepping property-groups (global/viewable by All tenants) by hand between instances and hoping for no human error.

 

Did no one think that through in development?

 

Is there a way through vRO, or another way, to set the property-group view from "All tenants" to a particular tenant?

 

Can't change it, or copy it through WebUI.

Re: The file specified is not a virtual disk error when opening a snapshot (original disk descriptor is missing)

The prepopulated size is the .vmdk file's size in bytes, and usually doesn't need to be changed.

If the Magic Number (the first 4 bytes) is iinvalid, then it's at least the file's metadata which is corrupt. At this point I'd usually ask to send me the first ~640kB of the .vmdk files, which is the metadata part. However, with overwritten files this part of the files could contain user data, so it may not be a good idea to post it on a public forum.

What might be an option is to use a hex editor and post a screenshot of the first few hunded bytes (for one of the .vmdk files). This might already be sufficient to see whether there's a chance to repair the files.

Hello James,

 

You may be able to get more specific logging about why/what component this is stalling on during this process by using ALT+F12 which will display the boot logging, can you upload a screenshot of this?

 

What version and build are you updating to and from and where did you procure the iso?

What other devices such as disks and SAN are attached to this host?

Re: Metal -- DX shaders not previously in OpenGL?

In this Tech Preview release, we're focusing on replacing the renderer from GL to Metal yet maintain the same DX library for the guest. Our graphics engineer can provide more info, but AFAIK, Metal provides less command compare to GL, e.g. there is no geometry shader available in Metal, where we actually need to implement as a part of the middle layer.

 

We're hoping to gain some performance improvement using Metal, as well as lower CPU load and longer battery life. But please keep the feedback flow in, we'd like to identify the gap and keep improving it down the road.

Hi jmtella,

 

Running Workstation on a Windows host which has Hyper-V enabled is not supported today. This is a nested virtualization across two different hypervisors.

 

Out team worked with the corresponding team at Microsoft and recognized this issue. Both parties would like to work together to resolve this issue but we don't have a specific timeline yet.

Dragon age origins has a similar problem, and the gamma adjustment is non-functional.  Not sure if it's a missing shader problem, or something else.

THe port on the ESXi host am able to Telnet to port 902 so that is working on the VMWare Host Machine.

Actually they are all filled with nulls for a solid part starting from the beginning, so seems like the snapshot is unrecoverable. But at least I will keep in mind what to do in the future in such cases, and it's good to know that I was able to properly recreate the descriptor file. Thank you for your help.

Re: VMware Horizon Client 4.5.0 REBOOT=Reallysuppress still reboots?

We discovered that even when specifying the correct "/norestart" switch there are some mandatory prerequisites that will still unexpectedly restart the system (This also happens with the Horizon Agent). We've only tested with Horizon Agent 7.1 and Horizon Client 4.5 but we found that if the following prerequisites were missing it will install them and restart the system. You then have to run the silent install again. We've seen multiple restarts depending on how many of the prerequisites are missing from the system.

Hi Bob,

 

Interestingly, I just removed the two drives that were in raid 0, leaving just a single disk (technically in raid 10), and it boots ok.

So must be something to do with the hard disks configured in raid 0.

 

It's a brand new install, not an update/upgrade, and the ISO was procured directly from vmware download site (latest build of 6.5).

 

Will try reconfiguring the two disks in some other fashion and see what happens

 

Thanks

James

Hi,

 

I was about to suggest to update to 12.5.7 but then remembered something else.

 

Are you running AVG or Avast antivirus at the host OS?


If so then see:

XP VM suddenly slow, Win 7 fine


for a solution on using both antivirus products along with VMware

TL;DR

In Avast Settings, troubleshooting you should uncheck the "Enable hardware-assisted virtualization" feature.

In AVG Settings, troubleshooting, uncheck "Enable hardware-assisted virtualization" feature.


If you are running BitDefender 2017 at the host then the only solution that I am aware about is to uninstall and revert to an older version of BitDefender.

 

If you are not running any of those antivirus products then my initial suggestion to first update to 12.5.7 still stands (which might be a good idea anyways)

Hello James,

 

That is good to hear, one of the reasons I asked what was locally attached is it could have been stalling at a similar point on drives as this:

experts-exchange.com/questions/28504727/Server-stuck-on-'vmkibft-loaded-successfully-5-5'.html

 

Same server model (DL380 G7) so was thinking it may have same or similar disks and thus the same issue.

What drives are these, how are they attached and do they have compatible firmware installed?

 

Bob
