Java virtual machine authentication / ssl requirements. Need to enable.

Hello,

 

I have been tasked with closing a vulnerability in our esxi 5.5 vcenter deployment which would allow arbitrary code to run without authentication or encryption.

 

When I set wrapper.java.additional.2=-Dcom.sun.management.jmxremote.authenticate=true and wrapper.java.additional.7=-Dcom.sun.management.jmxremote.ssl=true in the wrapper.conf file, and comment out the original 'false' entries, when I restart vSphere web client, it won't come back up and the following error comes up in noUser.log:

 

 

com.vmware.vise.extensionfw.impl.SpringBundleDeployer             Error creating a JMX connection to dm Server java.io.IOException: Failed to retrieve RMIServer stub: javax.naming.CommunicationException [Root exception is java.rmi.UnmarshalException: error unmarshalling return; nested exception is:

 

 

So setting JMX to authenticate and use SSL breaks the connection and the web client fails to come up. Any idea how to set it up so jmxremote uses ssl and password authentication?

FT is configured, but does not appear to work.

Hi,

 

I am testing out VMware's HA and FT ability's.

 

I have a test environment consisting of two ESXi hosts and a Windows Server system that will be used for the VM shared storage.

I went through and set up HA and successfully tested it by simulating a power failure on a single host by pulling the power.

HA did what I expected it to do and successfully restarted my test VM on the other host.

 

My next test was setting up FT, which did take me some time but I managed to set it up, or so I thought.

When I use the Test Fail over option I get an alert on the VM but it is still up and running. But I do notice that when I look at the VM at the cluster level the Primary is running but the Secondary is not.

The Fault Tolerance status says that its protected and I have a green tick for LockStep.

Also the Cluster compliant status says that its compliant.

But when I simulate a power loss on a host the VM goes down.

 

I have over looked something or miss configured my test environment?

 

Thanks,

 

Mark

I am a VM running low on space, Host is ESXI 5.1 and the VM is server 2008 R2.  This drive is just a storage disk on the host and has no OS on it.  The drive is provisioned thick can I just up the disk space in vSphere and then expand it in the OS without having issues or shutting down the VM?

import/export ovf template of vms with sharedisk

hi all,

      May I ask that whether vmware support to export/import ovf template of vms with sharedisk configure?

That means I have two oracle RAC nodes, which are configured as sharedisk as below:

Capture.PNG

Right now, I want to export these two nodes (included in one vapp ) as ovf template, but I found that rac-node-2 and rac-node-1 have independent vmdk. However, in my understanding, rac-node-2 should share the vmdk with rac-node-1.


So, how to export the ovf which can perform this sharedisk, or how to perform this sharedisk function without configure in vmware manually ?


Thanks A LOT.

Missing iSCSI Partition

November 11, 2015, 9:16 pm

Hi All, hoping for a little guidance... (hopefully this is in the correct group - apologies if not)

 

We have a vCenter with multiple hosts. Many of these hosts connected to a Storage Server (RHEL6) via iSCSI.  The storage server had (/has) a 3.4TB RAID 6 partition that was the iSCSI target. Something bad happened on the array (lost a disk) and somewhere along the way, it seems the partition may have been lost!

 

I've been reading as much as I can about the recovery processes, but a little unclear on some elements and could use some guidance please - as a non-linux expert!

 

1) Given this is iSCSI, the target partition (on the RedHat server) - the VMWare ESXi tools are or are not relevant? i.e. partedUtil etc. are for use with disks attached to the actual ESXi host itself?

2) I'm currently running a testdisk analyze on the RedHat server and it's finding lots of partition data, such as:

 

<snippet>

Warning: number of sectors per track mismatches 63 (NTFS) != 32 (HD)

  NTFS                 43727 165  4 48842  32  3   41734144

Warning: number of sectors per track mismatches 63 (NTFS) != 32 (HD)

  NTFS                 48842  32  3 53956 154  2   41734144

  ext3                 63315  83 11 67080   8 10   30720000

  ext3                 76499   5 27 80263 185 26   30720000

  ext3                 88835   4 19 92599 184 18   30720000

  ext4                 92686 207  3 92812  77  2    1024000

<eo snippet>

 

Given there's quite a lot and also a mix, is this actually the partition information of the GUESTS that were on the iSCSI device?

 

On the RedHat server, the parition appears in fdisk -l, but not in cat /proc/partitions - should it?  In fdisk, it also shows as a GPT disk - which I believe is correct.

 

Thanks in advance for any tips.

 

Cheers,

 

Anthony..

P2V VM's or newly created VM's can not ping outside of local network. Other's on the same ESXi host can ping without issues.

I have a ESXi 5.5 host that has 3 NICs connected in different networks. These networks are untagged and switchport does not have any security enabled on it. I see the arp changes on my firewall and the ACLs allow all traffic. The VMs are Windows 2003 R2 servers. Others that I have converted from physical seem to work fine without issues however there are some that just don't want to seem to behave correctly. Looked at routes on VMs and they look identical. This happens on both newly created VMs from scratch, aka DVD ISO build, and P2V. Any ideas?

As "Timekeeping in VMware Virtual Machine.pdf"says:

VMware virtual machines provide a  set of pseudoperformance counters that software running in the virtual machine can read with rdpmc instruction to obtain fine-grained time. To enable this feature, use the following configuration file setting:

monitor_control.pseudo_perfctrl=TRUE

How to customize username/password for Linux VM during deployment?

Hi,

 

I'm using the pyvmomi Python API binding, and deploy Linux VMs.

Part of this is to create a customization for hostname, NIC, ...

I'm currently looking at the available customization options, but not able to find one which would set a local user/password.

Is there something like this available, or do I need to do it myself once VM has been deployed?

 

Thanks,

Hello Dear community

I would like your opinions and advice on a very annoying problem.

We have a cluster of six ESXi servers 5.5U2 working well

Since now 1 month, each time after we vMotion some VM from one host to another

About 30 minutes later, the source host crashes, it starts with very slow VMs running on this source host

We are unable to connect directly on it using vSphere client

Destination host has no problem,

We tried several combination for source ---> destination, and it's always the source host that hang.

Hardware servers are up to date with firmware and are all exactly the same model

No errors in ESXi log file or server console

You help will be much appreciated

Cheers

Flip Flop Mouse Wheel

Hello.  Sometimes I think that the boss just doesn't think we have enough to do so he sends us off on a wild goose chase.  Maybe there is a logical reason for this request but I just don't know what it is.

 

So here we go.

 

We have been asked to find a way to reverse the default behavior of the mouse scroll wheel for users who request it in their desktop VMs.  Yes, they want to roll the wheel down on their mouse and have the document scroll up and vice versa.  (Maybe they are gamers and would find this useful during their lunch hour or something.)

 

On a physical Windows PC there is a registry key called flipflopwheel that can be changed to do this.  In a VM though, that key does not exist.  In fact there do not appear to be any Mouse Hardware ID related keys in the registry.  There is nothing in VMTools that I can see to alter this behavior either.

 

Any thoughts or suggestions?

ESXi 5.1 host craches few minutes after HA is configured on it

Hi everybody!

I have two hosts running ESXi 5.1 hypervisor. I manage both of them using vCenter. Everything is fine at this point. The issues comes when I create an HA Cluster and I move the hosts inside the cluster. In that moment HA is configured on the hosts and few minutes later a purple screen crash occur on both of them, not at the same time but they always crashes. The message wrote on the top of the purple screen is always like this:

 

#PF Exception 14 in world 8218:idle26 IP 0x418027ab7e7f addr 0x0 (The world value and CPU vary, but always is the same exception)

 

I analyzed the core dump file after the purple screen event and they always report some error when they try to access to the local disc just before the fail event.

The path "vmhba1:C0:T32:L0" referred in the error is the path to local disc. But here there is something weird. Because I have a Syslog Collector in my environment too, and when the hosts were outside the HA cluster, they reported the same, and they never had failed before. Do Anyone have some idea about what's happening?

We have an IBM Storwize 3700 SAN with two old IBM hosts connected via HBA-cards. They are on vSpehere 4.1 and work perfectly.

 

Two new HP Gen9 with dual HBA-cards have been installed with vSphere 5.5

 

On the SAN we have configured port mappings and all looks great there but only one LUN is actually recognized (there are actually 3) on one of the new servers.

 

The new servers have all patches and updates installed. Performing a Rescan won´t find any of the other LUN´s.

 

Rebooting the new servers did not help.

 

I kindly ask for advice.

 

Best regards

Trouble installing ESXi 5.5u3 on RAID-1 Setup (HP DL380 Gen9 / Intel B140i)

Hello,

 

 

I'm currently trying to setup an ESXi 5.5u3 on a HP DL380 Gen using a dual disk RAID1 configuration (Intel B140i SW controller). The image used for the setup ist the HP customized version (VMware-ESXi-5.5.0-Update3-3029944-HP-550.9.3.26-Sep2015.iso). After having setup the disks as a mirror they are accessible as a logical device during the installation. After the setup has finished the system boots the installed ESXi from the first disk but fails to load completely becaus it detects a second installation/disk with the same UUID of the first disk. After doing some research on this issue I disabled the lookup for duplicate images using the boot option "overrideDuplicateImageDetection". Afterwards I was able to configure the machine but I can not uses the configured RAID1 as a data store. My only option is to configure each disk seperately. Since I'm using the proposed Image by HP containing the drivers for the chipset I have no idea how to proceed from here. If anybody has an idea or similar issues any help would be greatly appreciated. Thanks in advance!

 

 

 

best regards,
