Just quick share from my experience: Use thin provision disk will not bring empty space to newly created guest VM. Change to thick (whatever type if you want) if it is necessary or justify (usually not). Side-notes: it have to be long enough process for the conversion to take place if you mentioned "consistency", ask your boss or system team to be ...

I am working with netapp NAS on nfs for couple ESXi clusters. The main way to run snapshots is using the ESX snapshots or this how it is done there. Using NetApp snapshots is mostly to allow "jumping" back no matter what is the state of the file which sometimes is a requirement. Deduplication is another story since it is good in many cases of central storage ...

It certainly works, but you should definitely keep some other means of accessing it around...

You'll need to look at the resource allocation policy for your dev environment (Organization VDC). If the RAM is overcommitted or there's a hard limit on the resource pool, coupled with HA “Disallow power on VMs that violate availability constraints”, you'll need to contact the administrator. This could also be something wrong with the VM template, but ...

I realize this is an old question, but my problem was not reading the available documentation for ghettoVCB/being a noob at setting up NFS. If you are using NFS as your target datastore, make sure your NFS export is set to use 'async'. Additionally, you can set "DISK_BACKUP_FORMAT = 2gbsparse" (as opposed to 'thin', etc.) in your ghettoVCB config, which will ...

You have to use nohup utility to prevent process exit on HUP signal

Ultimately this would come down to performance monitoring and profiling to see which sites are creating the most load. A 'busy' site might not cause performance hits depending on what it is doing. You would need to define the problem more specifically and ask specific questions. Do you have any resource contention issues (CPU, storage, memory, network) ...

The answer is clear: At the point where it's more beneficial to run the site in its own VM. What this point is is entirely dependent on your environment, but for low to medium traffic sites I always separated around technical concerns only, e.g. when I have contradictory technical requirements or need to separate more than it's possible with vhosts.

This is definitely look like a hardware error.You can try tool like mcelog which just act as a translator for any machine check exception(mce).You haven't menrioned which version of OS you are using but in RedHat/Centos you can install it via yum yum install mcelog and the message are logged in /var/log/mcelog For more info you can refer ...

Error message looks like you have a hardware problem with CPU or RAM. Have you tried running memtest or if available, a built-in hardware diagnostic tool which you can choose during the server boot?

The users on your Windows VM are local, right? I think you have to install SSO on this machine. That's the only option possible to make use of local operating system users. (see Identity Sources for vCenter Server with vCenter Single Sign-On) You'll have to reconfigure your VCSA to use this new SSO installation, though. edit: Change the vCenter Single ...

Here are a few suggestions. Is your ILO connected and configured? It will tell your exactly what's happening with the system. Please review the ILO4 log. View the system's IML log (available via ILO or vSphere "hardware" tab) Are there any indicators or error messages on the screen during crash or at POST? Are you using the HP-specific install of ESXi ...

My suggestion is to install a domain controller virtual machine. That's what the vSphere appliance works best with, and it's the native solution for your Windows RDS server. vSphere/vCenter is using Likewise to provide AD/LDAP integration. It expects either pure LDAP or Microsoft Active Directory. Think about the target market for paid vSphere; shops with ...

Notes Regarding ESX(i) AD Integration: What i've discovered (on ESXi 5.0) is when joining the ESXi host to the domain (GUI) the process via Likewise agent (on host) enumerates the trusted domains and domain controllers at the time of the join and populates a file in /etc/likewise/krb5-affinity.conf with each child/domain and associated DC. The process ...

The first thing to note is that you're not actually testing the SAN performance here. Since your IO benchmark is running on the C drive of the virtual machine, which I would guess is a virtual hard drive stored within the file system of one of those 2TB volumes (e.g. a VMDK stored within a VMware VMFS datastore). You have a lot of added layers to the I/O ...

If you're looking for an optimal full volume encryption solution, I'm not aware of one. An optimal solution would provide encryption on the host/storage level. This is easy to do with Hyper-V, but not so much with ESX. I'm surprised Microsoft does not use this more in Hyper-V marketing, but the reality is this scenario sadly demonstrates how important ...

So this is your setup: A bit complex, I would advise you to not do NIC bonding inside your VMs. Anyway: Both vmguest1 and 3 can ping host1 but not each other, right? To investigate this, start by issuing [root@vmguest1:~]# arp -a vmguest3 vmguest3.example.com (1.2.3.4) at <incomplete> on eth0 [root@vmguest1:~]# and use tcpdump to see what's ...

Bonding your NIC connections inside of a virtual machine is akin to using software RAID inside of a VMware guest. You can do it, but it's not a reasonable method of protection for a VMware system. Are you using managed switches? I'd recommend simplifying your solution: Place your VMs on the same vSwitch if they need to communicate with each other. The ...

Andre, One item that I always consider when replacing a motherboard is to ensure the exact same hardware is being replaced. As dartonw described if some of the components changed this may cause problems. The fact you received the copied/moved question in the "Summary" tab tells me the hardware is different. Just to be safe always check the HCL to be sure: ...

It looks like they aren't IDs at all but masks of what features are available: I assume that the "host" in hostCPUID is the actual raw CPUID bits reported to ESXi by the host's cpu GuestCPUID represents the feature bits exposed to the VM. In addition to your masking, there are masks applied based on the capabilities supported by the virtual ...

No, there's no way to make this work at present. ESXi only supports NFS v3.

As the size and number of snapshots on a virtual machine increase, so does the number of storage command operations within vmkernel. For each storage command issued by the virtual machine guest OS, multiple storage command operations may be necessary to traverse the entire snapshot chain to read the most appropriate block of data.

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 ...

Definitely try to 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, so 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 ...

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.

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 ...

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.

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?

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.
