Tell your network guys to create the network 192.168.101.0. Then add it as an additional VLAN to your existing uplink and add a port group for this network to your virtual switch. Or create a new virtual switch for this network and get yourself an uplink (you've got 5 NICs left) for this network. You wont have any downtime. If your VMs in 192.168.100.0 ...

Right-size your VMs. If you have enough free virtual CPUs to be concerned about "CPU parking", you may have too many allocated to the VM. It's not a common request, and I'd just rely on the traditional resource management tools unless you're currently having a performance problem. Edit: You are having a performance problem. Make sure you have VMware ...

It wouldn't matter. If you want to save power, allocate less cores to the VM guest. Windows will try to manage its "virtual" cores, but it has no control over the hypervisor so it wouldn't affect the actual physical CPUs on the system.

Passthrough of storage controllers is a tenuous solution at best. It's definitely been done... I did it when I thought there would be dear advantages to it. See: Hosting a ZFS server as a virtual guest But you're suffering from limited compatibility of motherboards/controllers, suboptimal performance characteristics, and in your case, a chicken-and-egg ...

I think this is doing exactly what you're asking it to. You're throttling the I/O capabilities and profile of your VMs, causing them to perform poorly. Don't do this. Micromanaging resources at the individual VM level can have unintended consequences and will complicate future troubleshooting. My recommendation is to NOT try to outsmart the VMware ...

Check the vmware syslog, an easy way is move the /scratch/log in advanced configuration to a datastore then download the syslog using the file manager in vsphere. Can also use the syslog collector http://blogs.vmware.com/vsphere/2011/07/setting-up-the-esxi-syslog-collector.html If you have guest specific problems and the hosts are fine, then it points ...

Apart from that each VM wil consume the RAM that you have assigned plus the over head . For example if your 3GB VM have 4vCPU's it will consume 3 GB + 300 MB , it depends on how many CPU's you are assigning for the virtual machine.Depends on vCPU's + Memory Allocated.

I wouldn't access the database directly if I was you. VMware might change the schema any time if they think it necessary. (That's why there's no documentation: You're not supposed to access the DB directly.) Try to get the information you need via PowerCLI, Ruby vSphere Console or something similar. There are also libs to access the vSphere API like VI Java ...

your script would look like #Shutdown get-vm -name XXX | shutdown-VMguest #wait 30 sec start-sleep -s 30 #it should be off get-vm -name XXX | set-vm -memoryGB 999 #Start it get-vm -name XXX | start-VM

You can use Raw Device Mapping to have a VM on ESXi access the data on Disk C. See: About Raw Device Mapping @ VMware.com. I don't think there's a way for you to access the data on Disk C from within ESXi without creating a VM. Here's the relevant VMware KB article on how to map the disk: Create RDM mappings. Procedure Select a target LUN and click ...

ESXi is most defintely not Linux or BSD based. The console that you can SSH into looks like a Unix shell, but the kernel that is running is custom. http://en.wikipedia.org/wiki/VMware_ESX#Technical_description As of version 4.1, VMWare has dropped development of ESX and now focuses exclusively on ESXi which does not include a Linux kernel. The code ...

There's a fling, Ruby vSphere Console, that you can make use of. If your Linux admins prefer Python they could use pyVmomi, but it's more of a library (although you can start Python, import pyVmomi and then use it as a "shell"). There's also virsh but it looks like you can't deploy templates with it. However, googleing for virsh + deploy + template I found ...

The only option I've found would be using the PySphere SDK I've used it to do snapshot consolidation and cleanup, but it can certainly do VM creation from a template.


2

A couple of thoughts on this... It's almost easier to install Linux operating systems anew if you have a deployment solution and configuration management in place (e.g. Cobbler and Puppet/Chef). I tend not to use vSphere templates for anything other than canned Windows server installations. If that's not possible, and the template deployment process is ...

If your 4 uplinks are equally used your config should be correct. (Although the switch really should know what you're doing!) It's interesting that you get a combined bandwidth of more or less exactly 1 Gbit/s. As far as I understand you're connected to only one physical switch, right? A shot in the dark: Maybe it has only one (active) 1GbE uplink?


1

A more specific limitation is at play here. VMware vSphere editions below the Enterprise licensing level do NOT support LACP. And even then, LACP is only available on the Distributed Switch, not Standard vSwitch. Can you provide more detail on what you're connecting to and why 4Gbps throughput is necessary? Are you encountering limitations already? Have you ...

If you want true link aggregation, as opposed to simple failover, this needs to be supported by the switch you are connecting your server to; this is called an etherchannel in Cisco speak, I don't know how other vendors call it. You need to configure four ports on the switch for link aggregation, and then create a single vSwitch in ESXi and bond all four ...

You can either have an internal vSwitch that is internal and can interconnect them with GRE-tunnels (which you don't want) or make the vSwitch external. There is no other way to interconnect vSwitches accross different networks.

It's the new ESXi 5.5 coredump partition. VMware found that it was often getting truncated logs because coredumps were running out of space. This makes troubleshooting very difficult so they created this partition for that. I haven't tested deleting it myself for a critically low space system but worth finding out if you have a testbed. The documentation ...

I had the same question. I use my servers for projects and have no need to run them 24/7, however, the problem that I've run into is the array batteries not charging and giving errors when I do finally boot up the servers again.

There's a fling that might help you: VMware OS Optimization Tool The VMware OS Optimization Tool helps optimize Windows 7/8/2008/2012 systems for use with VMware Horizon View. The optimization tool includes customizable templates to enable or disable Windows system services and features, per VMware recommendations and best practices, across ...

This doesn't look like something you should be rsyncing to/from an ESXi host. VMware is NOT a general-purpose operating system and the use of rsync is not supported. Hence the fact that you had to compile a static version of the utility. Can you find another approach to move/copy the data you have? If this is for backups, you really should be using ...

Here is what I discovered that the problem was. After being called away from this project due to a corporate merger, it was dumped back on my plate and I decided to restart from scratch. This time I created a LUN, RH_ISCSI_LV_001, and shared it out via the iscsi daemon. I was able to mount and format it in vSphere. Once again I unmounted the LUN and ...

Maybe try a basic approach of this issue : satisfy to the VMware High Availability requirements : All hosts must be licensed for vSphere HA (Licensing by features), You need at least two hosts in the cluster, All hosts VMKernel Management Network need to be configured with static IP addresses, There should be at least one management network in common among ...

There are different ways to change this option. All these solutions are listed in the VMware KB 2003637. About SSH, you might find useful the esxcli way with : vim-cmd hostsvc/advopt/update UserVars.SuppressShellWarning long 1 The full documentation : Cluster warning for ESXi Shell and SSH appear on an ESXi 5.x host

The defaults will do what you need without issue... That is, there's nothing in the default configuration that would preclude proper operation of vSphere 5.5. You may want to modify a few other BIOS settings, depending on your workload and usage patterns: Power Management: My applications care about latency, so I tend to disable the power and CPU-scaling ...

Sorry there has been a IP mistype in my original post. vswitch0 and vswitch1 is of same range apart from the subnets freesco range is 192.168.1 and it would ping and access 192.168.0 range with no issue but not the other way around my esxi host has two nics out of which only one is in use and its connected to another external unmanaged switch I have 9 ...

Depends how far you want to take it... This is less of a ESX question and more of general networking. Vlans if enforced properly are secure and if you put management on a separate VLAN, it will be isolated from the main data network. Just make sure you don't mess up your trunk ports and send a trunk to the ESXi data port that has management traffic. I ...

From the screenshot, I'm trying to guess : I noticed 7 virtual machine port groups in the "Networking" tab, that was created under this sub link of "Configuration" tab in your selected host. You have to specify which configuration you created. An example, if you created VM Network in the Standard Switch: vSwitch0 with only the Physical Adaptater vmnic0, VM ...

Try to define the username as MYDomain\MyUser E.g. {$USERNAME} => "vsphere.local\monitoring" Zabbix has a bug if you use @ in the username.

I have BL460c G1, and I simply use standard settings, but ensure Intel VT technologies, and Execute Disable Bit, or INTEL TXT (if you have) are enabled, they are madatory for ESXi 5.5

The extension module only helps you if you are using iSCSI with the host itself. Since you are using iSCSI from within the guest Dell's MPIO DSM for Windows should handle MPIO though I doubt that is possible with your current setup. Since the DSM relies on the fact that it has two physical NICs and not two virtual NICs connected to the same vSwitch which ...

The Dell Equallogic MEM is never required, even when you are using it for VMDK storage. VMware's built-in path selection policies will get the job done, though not quite as well (e.g. Round Robin, or the less-desirable default "Static" PSP). Since you're doing direct iSCSI access from your virtual machine, the host integration tools installation directly on ...

I have punted for this array, the problem I am having seems to be pointing back at the NAS4Free array, since I can use 9000 MTU for VMotion just fine (over the same NICs and switches, just different vNICs). I am going to create two iSCSI storage networks, one that operates as 1500 MTU and one that operates at 9000 MTU. When I transition my other SAN units to ...

It's available with a plugin. List of plugins for Vagrant are there: https://github.com/mitchellh/vagrant/wiki/Available-Vagrant-Plugins And there, it's the plugin for vagrant with vsphere as a provider: https://github.com/nsidc/vagrant-vsphere/ .

The Dell R900 is a quad-socket RAM and CPU-optimized server platform. The internal disk place is limited because it's intended to be connected to some form of shared-storage. PCI-X is defunct.
